In 2007 the residents of the town of Sannieshof in North West Province declared a dispute with the Tswaing Local Municipality on the grounds that the state of local service delivery left much to be desired. The ratepayers then formed the Sannieshof Inwoners Belastingbetalers Unie (SIBU) which literally took over the functions of local government of the town, functioning as a local government within a local government.
This article provides a historical narrative of the conflict between SIBU and Tswaing Local Municipality, a dispute which was taken as far as the provincial High Court. Then follows an outline of conditions in Sannieshof and the townships of Agisanang and Phelindaba. Attention is given to the perceptions of local residents on the prevalent conditions, specifically in respect of water supply and sanitation service delivery. In the third section there are some theoretical perspectives on political culture, socialisation and happiness. A debate is provided on how these phenomena manifest under existing conditions in Sannieshof, and more particularly, in its adjacent townships of Agisanang and Phelindaba.
Orientation: Local football contributes significantly to the social- and economic welfare of South Africa through its spectators. Understanding the motives and experiences of football spectators could provide opportunities for capitalising on football as revenue stream feeding the South African economy.
Research purpose: To investigate how motives for sport consumption predict intrinsic psychological reward of South African premier league football spectators.
Motivation for the study: Sport - particularly football - is an untapped resource for stimulating economic development and growth through its consumers. Spectators, who often experience their investment in the sport as deeply rewarding and meaningful, should participate more frequently in purchasing products or services associated with the sport. Through understanding the motives for sport consumption of South African premier league football spectators and the impact of these motives on intrinsic psychological reward experiences, football clubs are able to provide a targeted experience or service to spectators in order to further stimulate economic growth.
Research design, approach and method: A census sample of 806 football spectators attending various matches at a football stadium in Soweto was drawn. A cross-sectional research design was implemented. This research was exploratory and descriptive. Structural equation modelling was implemented to assess the factor structures of the constructs, to confirm composite reliability of the measures and to assess the structural paths between the variables.
Main findings: A predictive model for intrinsic psychological rewards (life satisfaction and meaning) through the motivation for sport consumption (individual – and game related factors) was confirmed. It was further established that motivation for sport consumption is significantly positively a) related to and b) associated with the experience of intrinsic psychological reward by South African football spectators. Practical/managerial implications: Football clubs should tailor spectator experiences around both individual and game related spectator motives in order to develop experiences associated with intrinsic psychological reward.
Contribution/value-add: The study contributes to consumer psychology research relating to the motives associated with the consumption of football within South Africa.
Orientation: Publishing methodologically sound, empirically based studies in reputable accredited scientific journals are essential in order to advance knowledge and evidence-based practice in the field of industrial and organisational psychology.
Research purpose: The purpose of the research was to conduct a broad content analysis of the articles published in the South African Journal of Industrial Psychology (SAJIP) between 2004 and 2013. The study aimed to provide a descriptive overview of the most frequent content themes,published authors and institutions, research approaches, strategies, designs and analysis techniques, software packages and sample sizes in industrial and organisational (I-O) psychology utilised in the publications.
Motivation for study: The periodic analyses of published content in scholarly journals provide an index of the extent to which the publications reflect the scope of practice in a given discipline and broaden insight into the direction and relevance of research published in a journal.
Research design, approach and method: A broad systematic content analysis was conducted of 342 documented articles published in the SAJIP between 2004 and 2013. Descriptive data(frequencies and percentages) were used to report the findings.
Main findings: The publishing pattern of the SAJIP appeared to correspond with its focus and scope. Manuscripts utilising mostly cross-sectional quantitative correlational research designs with large samples (n > 201) were published in the SAJIP. The University of Johannesburg and Professor Sebastiaan (Ian) Rothmann were the largest contributors to publications between 2004 and 2013. Organisational psychology and psychometrics were the most prominent domains in I-O psychology research. Data were predominantly processed utilising SPSS.
Practical implications: The insights derived from the findings can be employed to plan future research initiatives in the field of I-O psychology.
Contribution/value-add: The findings provide valuable insight into the current status of the foci of I-O psychology research as published in the SAJIP between 2004 and 2013 and the contribution made by the SAJIP to advancing knowledge and evidence-based practice in I-O psychology.
Orientation: The work of industrial/organisational (I/O) psychologists presents an interesting and relevant context for studying meaning and engagement as components of happiness. Research purpose: The aim of this study was to determine how I/O psychologists experience the meaning of their work and to investigate the relationships between their experiences of work-role fit, meaning of work, psychological meaningfulness and work engagement, utilising the happiness framework proposed by Seligman (2002). Motivation for the study: I/O psychologists spend more than 88% of their working day with people, and they are primary role models for happiness in the workplace. Information about their work engagement and experiences of meaning is therefore needed. Research design, approach and method: A survey design was used. A convenience sample (n = 106) was taken of I/O psychologists in South Africa. A biographical questionnaire, the Work-Role Fit Scale, the Work-Life Questionnaire, the Psychological Meaningfulness Scale, the Work Engagement Scale and a survey measuring the actual and desired time spent on six broad categories of work were administered. Main findings: Work-role fit predicted psychological meaningfulness and work engagement. The calling orientation to work predicted both psychological meaningfulness and work engagement. Work-role fit mediated the relationship between the meaning of work and psychological meaningfulness. Work-role fit partially mediated the relationship between a calling orientation to work and work engagement. Practical implications: A calling orientation to work should be fostered in I/O psychologists because it contributes to experiences of work-role fit, psychological meaningfulness and work engagement. Contribution/value-add: The results of this study contribute to scientific knowledge about work-role fit, engagement and meaning as components of happiness of I/O psychologists.
In view of the aging and dejuvenation of the working population and the expected shortages in employees’ skills in the future, it is of utmost importance to focus on older workers’ employability in order to prolong their working life until, or even beyond, their official retirement age. The primary aim of the current study was to examine the relationship between older workers’ employability (self-)perceptions and their intention to continue working until their official retirement age. In addition, we studied the role of potential antecedents of their perceived employability at three different levels: training and education in current expertise area as well as in an adjacent expertise area (individual level factor), learning value of the job (job level factor), and organizational career management practices (organizational level factor). Data were collected by means of e-questionnaires that were distributed among two groups of Dutch older (45-plus) white collar workers. The samples consisted of 223 employees of an insurance company, and 325 university workers, respectively. Our research model was tested separately in each sample using Structural Equation Modeling. We controlled for effects of respondents’ (self-)perceived health and (self-)perceived financial situation. Similar results were found for both samples. First, the relationship of perceived employability with the intention to continue working until one’s retirement age was positive, whereas the relationship between a perceived good financial situation with the intention to continue working until one’s retirement age was negative. Secondly, as regards the potential antecedents, results showed that the learning value of the job was positively related to perceived employability. In addition, an employee’s perception of good health is a relevant correlate of perceived employability. So, whereas perceived employability contributes to the intention to continue working until one’s retirement age, a good financial situation is a push factor to retire early. In order to promote the labor participation of older workers, this study indicates that organizations should focus on the learning possibilities that are inherent to one’s job rather than on providing additional training or career management. Further research is needed to test the generalizability of our results to other samples.

Perspectives of female leaders on sense of coherence and mental health in an engineering environment
(2013)
Orientation: Positive organisational behaviour impacts strongly on various individual and work-related outcomes. Gender perspectives in this paradigm have not yet been comprehensively researched.
Research purpose: This article explores female perspectives on mental health and sense of coherence. The aim is to promote an understanding of gender-related subjective perceptions on mental health and sense of coherence from an emic perspective.
Motivation for the study: Limited research exists regarding the perceptions of positive leadership behaviour of female leaders within South African who experience unique challenges within the business environment and remain healthy at the same time.
Research design, approach and method: Data from a mixed-method research study are presented, thereby providing insights into quantitative and in-depth qualitative empirical data from 15 female leaders. The study followed a single, embedded case study approach.
Main findings: The main findings show that sense of coherence, mental health and gender awareness are connected. Female leaders with a high sense of coherence refer to gender in a positive or neutral way in a male-dominated work environment. The results emphasise individual and social health-promoting strategies in an organisation and the way personal life orientation contributes to individual (mental) health.
Practical/managerial implications: Organisations need to focus more on promoting mental health in terms of gender and gender-related positive psychology frames.
Contribution/value-add: This study contributes to the literature on gender within the positive organisational behaviour paradigm, presents recommendations for future research and highlights the practical implications for organisations.
Orientation: Employees’ perceptions of their leaders’ behaviour play a role in creating empowering environments where employees are willing to do more than what is expected, with retention of employees as a result. Research purpose: The aim of this study was to theoretically conceptualise and empirically determine the relationships between employees’ perception of their leaders’ empowering behaviour, psychological empowerment, organisational citizenship behaviours and intention to leave within a manufacturing division of an organisation. Motivation for the study: In the ever-changing work environment, organisations must capitalise on their human capital in order to maintain competitiveness. It is therefore important to identify the role of employees’ perception of leadership in contributing to the establishment of an environment where employees feel empowered, are willing to do more than what is expected and want to stay in the organisation. Research design, approach and method: A non-experimental, cross-sectional survey design was used. The total population (N = 300) employed at the manufacturing division was targeted. Two hundred completed questionnaires were obtained. The Leader Empowering Behaviour Questionnaire, Measuring Empowerment Questionnaire, Organisational Citizenship Behaviour Questionnaire and Intention to Leave Scale were administered. Main findings: Employees’ perception of their leaders’ empowering behaviour (keeping employees accountable, self-directed decision-making and people development), psychological empowerment (attitude and influence) and organisational citizenship behaviours (loyalty, deviant behaviour and participation) predict intention to leave the organisation. Practical/managerial implications: Organisations should foster the elements of a positive organisation, in this case leader empowering behaviours, if they want to retain their employees. Contribution/value-add: The results of this research contribute to scientific knowledge about the positive effects of employees experiencing their leaders as empowering.
Orientation: Lack in congruence amongst industrial and organisational psychologists (IOPs) as to the conceptualisation of its profession poses a significant risk as to the relevance, longevity and professional identity of the profession within the South African context. Research purpose: This study aimed to explore the professional identity of IOPs within the South African context. Specifically, the aim of this study was four-fold: (1) to develop a contemporary definition for IOP, (2) to investigate IOP roles, (3) to determine how the profession should be labelled and (4) to differentiate IOP from human resource management (HRM) from IOPs’ perspectives within South Africa. Motivation for the study: IOPs do not enjoy the same benefits in stature or status as other professions such as medicine, finances and engineering in the world of work. IOPs need to justify its relevance within organisational contexts as a globally shared understanding of ‘what it is’, ‘what it does’ and ‘what makes it different from other professions’, which is non-existent. In order to enhance its perceived relevance, clarity as to IOPs professional identity is needed. Research design, approach and method: A post-positivistic qualitative content analytic and descriptive research design was employed in this study. Data from practising industrial and organisational psychology (IOP) within South Africa (N = 151) were gathered through an electronic web-based survey and were analysed through thematic content analysis. Main findings: The results indicate that IOP in South Africa seeks to optimise the potential of individuals, groups, organisations and the community by implementing scientific processes to support both individual and organisational wellness and sustainability. ‘Work Psychology’ was considered a more fitting professional designation or label than industrial and/or organisational psychology. The industrial psychologist’s major roles related to the well-being and development of employees. A clear distinction between a more dynamic, pro-active approach of IOP compared to a more transactional approach of HRM was also evident. IOP within South Africa appears to have a community development function. Practical/managerial implications: The longevity, relevance and impact of IOP as a profession requires alignment amongst practitioners as to shared common professional identity. Contribution/value-add: This study provides a contemporary understanding of the roles, functions, labels and unique value proposition of industrial and organisational psychology within the South African context.
The information and communication technology (ICT) sector within the Netherlands is a major driver of globalization, the country’s economic growth and innovation. The Dutch ICT sector’s performance is increasingly becoming dependent upon employee driven innovations in order to address the needs of the sectors they service. In other words, the ICT sector within the Netherlands is largely dependent upon the performance and innovative capacity of its employees; both of which are functions of employee engagement. Given the high demand, and low supply of talent within this sector, ICT organizations need to develop innovative ways to enhance the performance capacities of its people. Developing an engaged and highly innovative workforce seems to be an efficient way to activate employees’ performance. As such, the aim of this paper was to investigate the mediating function of employee driven innovative work behaviors in the relationship between work engagement and task performance within the a Dutch ICT consulting firm. A cross-sectional survey-based research design, employing a census-based sampling method, was employed to obtain data from a global ICT consulting firm within the Netherlands (n = 232). The Utrecht Work Engagement Scale, the Innovative Work Behavior Scale and the Task Performance Scale was used to assess the associative subjective experiences of ICT employees. The results showed that work engagement is a significant driver for innovative work behaviors, which in turn affects the task performance of employees. Further, innovative work behaviors are therefore important to translate the engaging energies of employees into performance. This paper discusses the theoretical and practical implications of these findings.
The purpose of this study was to identify distinctive mental health profiles for industrial psychologists based on the Mental Health Continuum. Further, it aimed to determine how these profiles differ with respect to work-role fit, meaningfulness and work engagement. It also aimed to investigate whether industrial psychologists within managerial or specialist differ in respect of different types of mental health. An online cross-sectional survey design was employed to draw a census sample (n = 274) from all South African industrial psychologists. A biographical questionnaire, the Work-Role Fit Scale, the Psychological Meaningfulness Scale, the Work Engagement Scale, and the Mental Health Continuum–Short Form were administered. Descriptive statistics, correlations, latent profile analysis, MANOVAs and ANOVAs were computed. Three mental health profiles for industrial psychologists were identified: languishing, moderately mentally healthy and flourishing. Significant differences between the three mental health profiles and experiences of meaningful work-role fit and work engagement were found, but not between experiences of managerial roles. The results show that individuals with different mental health profiles, experience work and its related outcomes, differently. Therefore, in order to enhance meaningful work-role fit and work engagement of industrial psychologists, a one-size-fits-all model may not be appropriate.
Psychological ownership is a cognitive–affective construct based on individuals’ feelings of possessiveness towards and of being psychologically tied/attached to objects that are material (e.g. tools or work) and immaterial (e.g. ideas or workspace) in nature. Research suggests that psychological ownership could be influenced by various individual, organisational and contextual factors. The South African Employment Equity Act, which was implemented to grant equitable opportunities to previously disadvantaged employees, could be a significant contextual factor affecting psychological ownership, due to perceptions associated with inequality. Ethnicity may also act as a moderator for the relationship between perceptions of employment equity and psychological ownership. The objective of this study was to investigate the relationship between employment equity perceptions and psychological ownership and to explore whether ethnicity plays a moderating role in the relationship. A cross-sectional survey design was employed with a purposeful sample of 202 respondents employed in a large South African mining house. Pearson product–moment correlations and structural equation modelling confirmed that employment equity perceptions could predict the five components of psychological ownership. However, the results revealed that ethnicity has no moderating effect on the relationship between perceptions of employment equity and the emergence of psychological ownership. By implication, organisations that seek to retain employees targeted through equity initiatives need to find ways to enhance and develop the psychological ownership of these employees. The research contributes new insights into and knowledge of how contextual factors could influence employees’ psychological ownership.
Objective: Although meaning making and specifically autobiographical reasoning are expected to relate to well‐being, findings tend to be mixed. Attempts at meaning making do not always lead to meaning made. We aimed to disentangle these complex relationships and also explore the role of level of education.
Method: Ninety participants (mean age 36.73 years, SD = 7.27; 74.4% women, 25.6% men) who had experienced the loss of a parent through death, going missing, or Alzheimer's disease narrated this loss, a sad, a turning point, and a self‐defining memory, and completed questionnaires assessing depression, trauma symptoms, and protracted grief. Three aspects of autobiographical reasoning (quantity, valence, and change‐relatedness of self‐event connections) were related to meaning made (sophistication of meaning making) and symptom level.
Results: Years of education correlated both with positive implications of autobiographical reasoning and with meaning made. The quantity, positivity, and change‐relatedness of attempts at meaning making (self‐event connections) predicted accomplished meaning made, and positivity alone predicted less prolonged grief.
Conclusions: Adapting the life story after a loss such that change of the self is acknowledged and positive change can be constructed helps finding meaning and lowering protracted grief. These changes in narrative identity are supported by more years of education.
The relationship between exhaustion and work engagement has received considerable attention during the past decades. Although the theoretical proposition exists that work engagement may increase exhaustion over time, previous research has been mixed. Drawing on the transactional stress model and applying latent growth modeling, we aim to provide a more comprehensive picture of the work engagement–exhaustion relationship over time. In two longitudinal studies, with four measurement points each, we found consistent evidence that a higher initial work engagement related to increased exhaustion over time. Consistent with our hypotheses, a higher initial work engagement also related to less initial exhaustion, and increases in work engagement related to decreases in exhaustion over time. However, contrary to our expectations, a higher initial exhaustion related to elevated work engagement over time. In conclusion, our findings suggest that engaged employees are less exhausted but face a higher risk of exhaustion over time. At the same time, exhausted employees are less engaged, but they have the potential to become more so over time. The theoretical and practical implications of these findings will be discussed in this paper.
This study investigated whether prompting children to generate predictions about an outcome facilitates activation of prior knowledge and improves belief revision. 51 children aged 9–12 were tested on two experimental tasks in which generating a prediction was compared to closely matched control conditions, as well as on a test of executive functions (EF). In Experiment 1, we showed that children exhibited a pupillary surprise response to events that they had predicted incorrectly, hypothesized to reflect the transient release of noradrenaline in response to cognitive conflict. However, children's surprise response was not associated with better belief revision, in contrast to a previous study involving adults. Experiment 2 revealed that, while generating predictions helped children activate their prior knowledge, only those with better inhibitory control skills learned from incorrectly predicted outcomes. Together, these results suggest that good inhibitory control skills are needed for learning through cognitive conflict. Thus, generating predictions benefits learning – but only among children with sufficient EF capacities to harness surprise for revising their beliefs.

This article reports an investigation of how inhibition contributes to fluid reasoning when it is decomposed into the reasoning ability, item-position, and speed components to control for possible method effects. Working memory was also taken into consideration. A sample of 223 university students completed a fluid reasoning scale, two tasks tapping prepotent response inhibition, and two working memory tasks. Fixed-links modeling was used to separate the effect of reasoning ability from the effects of item-position and speed. The goodness-of-fit results confirmed the necessity to consider the reasoning ability, item-position, and speed components simultaneously. Prepotent response inhibition was only associated with reasoning ability. This association disappeared when working memory served as a mediator. Taken together, these results reflect the inhomogeneity of what is tapped by the fluid reasoning scale on one hand and, on the other, suggest inhibition as an important component of working memory.
In this explorative study, we investigate how sequences of behaviour are related to success or failure in complex problem‐solving (CPS). To this end, we analysed log data from two different tasks of the problem‐solving assessment of the Programme for International Student Assessment 2012 study (n = 30,098 students). We first coded every interaction of students as (initial or repeated) exploration, (initial or repeated) goal‐directed behaviour, or resetting the task. We then split the data according to task successes and failures. We used full‐path sequence analysis to identify groups of students with similar behavioural patterns in the respective tasks. Double‐checking and minimalistic behaviour was associated with success in CPS, while guessing and exploring task‐irrelevant content was associated with failure. Our findings held for both tasks investigated, from two different CPS measurement frameworks. We thus gained detailed insight into the behavioural processes that are related to success and failure in CPS.
Workaholism and overcommitment are often used as interchangeable constructs describing an individual’s over-involvement toward their own job. Employees with high levels in both constructs are characterized by an excessive effort and attachment to their job, with the incapability to detach from it and negative consequences in terms of poor health and job burnout. However, few studies have simultaneously measured both constructs, and their relationships are still not clear. In this study, we try to disentangle workaholism and overcommitment by comparing them with theoretically related contextual and personal antecedents, as well as their health consequences. We conducted a nonprobability mixed mode research design on 133 employees from different organizations in Italy using both self- and other-reported measures. To test our hypothesis that workaholism and overcommitment are related yet different constructs, we used partial correlations and regression analyses. The results confirm that these two constructs are related to each other, but also outline that overcommitment (and not workaholism) is uniquely related to job burnout, so that overcommitment rather than workaholism could represent the true negative aspect of work drive. Additionally, workaholism is more related to conscientiousness than overcommitment, while overcommitment shows a stronger relationship with neuroticism than workaholism. The theoretical implications are discussed.
Virtual reality (VR) headsets offer a large and immersive workspace for displaying visualizations with stereoscopic vision, as compared to traditional environments with monitors or printouts. The controllers for these devices further allow direct three-dimensional interaction with the virtual environment. In this paper, we make use of these advantages to implement a novel multiple and coordinated view (MCV) system in the form of a vertical stack, showing tilted layers of geospatial data. In a formal study based on a use-case from urbanism that requires cross-referencing four layers of geospatial urban data, we compared it against more conventional systems similarly implemented in VR: a simpler grid of layers, and one map that allows for switching between layers. Performance and oculometric analyses showed a slight advantage of the two spatial-multiplexing methods (the grid or the stack) over the temporal multiplexing in blitting. Subgrouping the participants based on their preferences, characteristics, and behavior allowed a more nuanced analysis, allowing us to establish links between e.g., saccadic information, experience with video games, and preferred system. In conclusion, we found that none of the three systems are optimal and a choice of different MCV systems should be provided in order to optimally engage users.
The article reports three simulation studies conducted to find out whether the effect of a time limit for testing impairs model fit in investigations of structural validity, whether the representation of the assumed source of the effect prevents impairment of model fit and whether it is possible to identify and discriminate this method effect from another method effect. Omissions due to the time limit for testing were not considered as missing data but as information on the participants’ processing speed. In simulated data the presence of a time-limit effect impaired comparative fit index and nonnormed fit index whereas normed chi-square, root mean square error of approximation, and standardized root mean square residual indicated good model fit. The explicit consideration of the effect due to the time limit by an additional component of the model improved model fit. Effect-specific assumptions included in the model of measurement enabled the discrimination of the effect due to the time limit from another possible method effect.
Recent research has identified significant correlations between traumatic events and depression in refugees. However, few studies have addressed the role of acculturation strategies in this relationship. This study explored the relationship between cultural orientation, traumatic events and depression in female refugees from Syria, Afghanistan, Eritrea, Iran, Iraq, and Somalia living in Germany. We expected acculturation strategies to moderate the effect of traumatic experiences on depression. The sample included 98 female refugees in Germany. The depression scale of the Hopkins Symptom Checklist (HSCL) represented the dependent measure. The trauma checklists derived from the Post-traumatic Diagnostic Scale (PDS) and the Harvard Trauma Questionnaire (HTQ) as well as the Frankfurt Acculturation Scale (FRACC) were used as independent measures for traumatic events and orientation toward the host culture as well as orientation toward the culture of origin, respectively. A moderation analysis was conducted to examine whether the relationship between the number of traumatic events and depression was influenced by the women’s orientation toward the culture of origin and the host culture. We identified a significant model explaining 26.85% of the variance in depressive symptoms (Cohen’s f2 = 0.37). The number of traumatic events and the orientation toward the host culture exerted significant effects on depressive symptoms. The moderating effect was not significant, indicating that the effect of the number of traumatic events was not influenced by cultural orientation. Based on our results, orientation toward the host culture as well as traumatic experiences exert independent effects on depressive symptoms in refugees.
A question of striking the right balance : how do digital media influence how we think and act?
(2020)
What influence do digital technologies have on human perception, thinking and action? Do computer games harm the development of young brains? And is there really such a thing as »digital dementia«, an increasing forgetfulness caused by the use of modern technologies? For some of these questions, answers are available that are empirically corroborated.
Auf das richtige Maß kommt es an : wie beeinflussen digitale Medien unser Denken und Handeln?
(2020)
Welchen Einfluss haben digitale Technologien auf das menschliche Wahrnehmen, Denken und Handeln? Schaden Computerspiele der Entwicklung junger Gehirne? Und gibt es tatsächlich so etwas wie eine »digitale Demenz«, eine durch die Nutzung moderner Technologien bedingte wachsende Vergesslichkeit? Auf einige dieser Fragen gibt es bereits Antworten, die empirisch belegt sind.
Background: The year 2016 has marked the highest number of displaced people worldwide on record. A large number of these refugees are women, yet little is known about their specific situation and the hurdles they have to face during their journey. Herein, we investigated whether sociodemographic characteristics and traumatic experiences in the home country and during the flight affected the quality of life of refugee women arriving in Germany in 2015–2016.
Methods: Six hundred sixty-three women from six countries (Afghanistan, Syria, Iran, Iraq, Somalia, and Eritrea) living in shared reception facilities in five distinct German regions were interviewed by native speakers using a structured questionnaire. Sociodemographic data and information about reasons for fleeing, traumatic experiences, symptoms, quality of life, and expectations towards their future were elicited. All information was stored in a central database in Berlin. Descriptive analyses, correlations, and multivariate analyses were performed.
Results: The most frequent reasons cited for fleeing were war, terror, and threat to one’s life or the life of a family member. Eighty-seven percent of women resorted to smugglers to make the journey to Europe, and this significantly correlated to residence in a war zone (odds ratio (OR) = 2.5, 95% confidence interval (CI) = 1.4–4.6, p = 0.003) and homelessness prior to fleeing (OR = 2.1, 95% CI = 1–4.3, p = 0.04). Overall the described quality of life by the women was moderate (overall mean = 3.23, range of 1–5) and slightly worse than that of European populations (overall mean = 3.68, p < 0.0001). The main reasons correlating with lower quality of life were older age, having had a near-death experience, having been attacked by a family member, and absence of health care in case of illness.
Conclusions: Refugee women experience multiple traumatic experiences before and/or during their journey, some of which are gender-specific. These experiences affect the quality of life in their current country of residence and might impact their integration. We encourage the early investigation of these traumatic experiences to rapidly identify women at higher risk and to improve health care for somatic and mental illness.
Background/Objectives: Sharing the bed with a partner is common among adults and impacts sleep quality with potential implications for mental health. However, hitherto findings are contradictory and particularly polysomnographic data on co-sleeping couples are extremely rare. The present study aimed to investigate the effects of a bed partner's presence on individual and dyadic sleep neurophysiology.
Methods: Young healthy heterosexual couples underwent sleep-lab-based polysomnography of two sleeping arrangements: individual sleep and co-sleep. Individual and dyadic sleep parameters (i.e., synchronization of sleep stages) were collected. The latter were assessed using cross-recurrence quantification analysis. Additionally, subjective sleep quality, relationship characteristics, and chronotype were monitored. Data were analyzed comparing co-sleep vs. individual sleep. Interaction effects of the sleeping arrangement with gender, chronotype, or relationship characteristics were moreover tested.
Results: As compared to sleeping individually, co-sleeping was associated with about 10% more REM sleep, less fragmented REM sleep (p = 0.008), longer undisturbed REM fragments (p = 0.0006), and more limb movements (p = 0.007). None of the other sleep stages was significantly altered. Social support interacted with sleeping arrangement in a way that individuals with suboptimal social support showed the biggest impact of the sleeping arrangement on REM sleep. Sleep architectures were more synchronized between partners during co-sleep (p = 0.005) even if wake phases were excluded (p = 0.022). Moreover, sleep architectures are significantly coupled across a lag of ± 5min. Depth of relationship represented an additional significant main effect regarding synchronization, reflecting a positive association between the two. Neither REM sleep nor synchronization was influenced by gender, chronotype, or other relationship characteristics.
Conclusion: Depending on the sleeping arrangement, couple's sleep architecture and synchronization show alterations that are modified by relationship characteristics. We discuss that these alterations could be part of a self-enhancing feedback loop of REM sleep and sociality and a mechanism through which sociality prevents mental illness.
Members of conflicting groups experience threats to different identity dimensions, resulting in the need to restore the aspect of identity that was threatened. Do these needs translate into specific goals in social interactions? In the present research, we examined the hypotheses that (1) experiencing one’s ingroup as illegitimately disadvantaged or victimized arouses agentic goals (to act and appear assertive and confident) when interacting with the advantaged or victimizing group, while (2) experiencing one’s ingroup as illegitimately advantaged or perpetrating transgressions arouses communal goals (to act and appear warm and trustworthy) when interacting with the disadvantaged or victimized group. Study 1 (N = 391) generally supported both hypotheses across diverse intergroup contexts involving gender, national/ethnic, and consumer identities. Study 2 (N = 122) replicated this pattern in a context of occupational identities. Study 2 further showed that the effect of ingroup role on agentic and communal intergroup goals was not moderated by participants’ general dispositional preferences for agentic and communal goals in interpersonal interactions, thus demonstrating how ingroup role exerts a distinct and robust influence on goals for interactions with other groups. Theoretical and practical implications are discussed.
The present research investigates if and how a more digitally centered communication between supervisors and employees satisfies employees’ needs regarding the communication with their supervisors and influences employees’ attitudes toward the supervisor and the job. In a cross-sectional online study, 261 employees rated their supervisors’ actual and ideal use of different communication channels (i.e., telephone, face-to-face, email) regarding quality and quantity. Employees’ job satisfaction and their perceptions of their supervisors’ effectiveness and team identification were measured as dependent variables. Employees perceived face-to-face communication to be of higher quality than telephone and email communication, and they indicated a preference for more face-to-face communication with their supervisors than they actually had. Moreover, the perceived quality of communication, especially via face-to-face, was strongly and positively related to the dependent variables. These results provide insights into potential problems of increasing e-leadership in organizations. We conclude with recommendations to reduce these problems.
Background: A growing number of studies are questioning the validity of current DSM diagnoses, either as "discrete" or distinct mental disorders and/or as phenotypically homogeneous syndromes. In this study, we investigated how symptom domains in patients with a main diagnosis of obsessive-compulsive disorder (OCD), panic disorder (PD) and social anxiety disorder (SAD) coaggregate. We predicted that symptom domains would be unrelated to DSM diagnostic categories and less likely to cluster with each other as severity increases.
Methods: One-hundred eight treatment seeking patients with a main diagnosis of OCD, SAD or PD were assessed with the Dimensional Obsessive-Compulsive Scale (DOCS), the Social Phobia Inventory (SPIN), the Panic and Agoraphobia Scale (PAS), the Anxiety Sensitivity Index-Revised (ASI-R), and the Beck Depression and Anxiety Inventories (BDI and BAI, respectively). Subscores generated by each scale (herein termed "symptom domains") were used to categorize individuals into mild, moderate and severe subgroups through K-means clusterization and subsequently analysed by means of multiple correspondence analysis.
Results: Broadly, we observed that symptom domains of OCD, SAD or PD tend to cluster on the basis of their severities rather than their DSM diagnostic labels. In particular, symptom domains and disorders were grouped into (1) a single mild "neurotic" syndrome characterized by multiple, closely related and co-occurring mild symptom domains; (2) two moderate (complicated and uncomplicated) "neurotic" syndromes (the former associated with panic disorder); and (3) severe but dispersed "neurotic" symptom domains.
Conlusion: Our findings suggest that symptoms domains of treatment seeking patients with OCD and anxiety disorders tend to be better conceptualized in terms of severity rather than rigid diagnostic boundaries.
Professionalization of service-learning in higher education – an academic development approach
(2018)
In an attempt to professionalize service-learning in higher education, teachers and their teaching skills are considered a determining factor and require particular attention. To promote the teaching skills necessary for service-learning courses, an academic development approach addressing these specific requirements has been implemented at Goethe University Frankfurt as part of the academic development program for teaching staff. This article presents the particularities of this approach and illustrates one of its central elements, i.e., the concept of a workshop on planning service-learning courses. Both practical and research implications are discussed.
Body dysmorphic disorder (BDD), together with its subtype muscle dysmorphia (MD), has been relocated from the Somatoform Disorders category in the DSM-IV to the newly created Obsessive-Compulsive and Related Disorders category in the DSM-5. Both categorizations have been criticized, and an empirically derived classification of BDD is lacking. A community sample of N = 736 participants completed an online survey assessing different psychopathologies. Using a structural equation modeling approach, six theoretically derived models, which differed in their allocation of BDD symptoms to various factors (i.e. general psychopathology, somatoform, obsessive-compulsive and related disorders, affective, body image, and BDD model) were tested in the full sample and in a restricted sample (n = 465) which indicated primary concerns other than shape and weight. Furthermore, measurement invariance across gender was examined. Of the six models, only the body image model showed a good fit (CFI = 0.972, RMSEA = 0.049, SRMR = 0.027, TLI = 0.959), and yielded better AIC and BIC indices than the competing models. Analyses in the restricted sample replicated these findings. Analyses of measurement invariance of the body image model showed partial metric invariance across gender. The findings suggest that a body image model provides the best fit for the classification of BDD and MD. This is in line with previous studies showing strong similarities between eating disorders and BDD, including MD. Measurement invariance across gender indicates a comparable presentation and comorbid structure of BDD in males and females, which also corresponds to the equal prevalence rates of BDD across gender.
Within the context of eHealth interventions, a shared understanding of what constitutes engagement in and with eHealth technologies is missing. A clearer understanding of engagement could provide a valuable starting point for guidelines relating to the design and development of eHealth technologies. Given the cross-disciplinary use of the term “engagement,” investigating how engagement (and its components) is conceptualized in different domains could lead to determining common components that are deemed important for eHealth technological design. As such, the aim of this paper was 3-fold: (a) to investigate in which domains engagement features, (b) to determine what constitutes engagement in these different domains, and (c) to determine whether there are any common components that seem to be important. A comprehensive systematic scoping review of the existing literature was conducted in order to identify the domains in which engagement is used, to extract the associated definitions of engagement, and to identify the dimensionality or components thereof. A search of five bibliographic databases yielded 1,231 unique records. All titles, abstracts, and full texts were screened based on specific inclusion and exclusion criteria. This led to 69 articles being included for further analyses. The results showed that engagement is used in seven functional domains, categorized as follows: student (n = 18), customer (n = 12), health (n = 11), society (n = 10), work (n = 9), digital (n = 8), and transdisciplinary (n = 1) domains. It seems that some domains are more mature regarding their conceptualization and theorizing on engagement than others. Further, engagement was found to be predominantly conceptualized as a multidimensional construct with three common components (behavior, cognition, and affective) shared between domains. Although engagement is prolifically used in different disciplines, it is evident that little shared consensus as to its conceptualization within and between domains exists. Despite this, engagement is foremost seen as a state of being engaged in/with something, which is part of, but should not be confused with, the process of engagement. Behavior, cognition, and affect are important components of engagement and should be specified for each new context.
In the present paper, we tested the ability of individuals to judge correctly whether athletes are lying or telling the truth. For this purpose, we first generated 28 videos as stimulus material: in half of the videos, soccer players were telling the truth, while in the other half, the same soccer players were lying. Next, we tested the validity of these video clips by asking N = 65 individuals in a laboratory experiment (Study 1a) and N = 52 individuals in an online experiment (Study 1b) to rate the level of veracity of each video clip. Results suggest that participants can distinguish between true and false statements, but only for some clips and not for others, indicating that some players were better at deceiving than others. In Study 2, participants again had to make veracity estimations, but we manipulated the level of information given, as participants (N = 145) were randomly assigned to one of three conditions (regular video clips, mute video clips, and only the audio stream of each statement). The results revealed that participants from the mute condition were less accurate in their veracity ratings. The theoretical and practical implications of these findings are discussed.
The marketing materials of remote eye-trackers suggest that data quality is invariant to the position and orientation of the participant as long as the eyes of the participant are within the eye-tracker’s headbox, the area where tracking is possible. As such, remote eye-trackers are marketed as allowing the reliable recording of gaze from participant groups that cannot be restrained, such as infants, schoolchildren and patients with muscular or brain disorders. Practical experience and previous research, however, tells us that eye-tracking data quality, e.g. the accuracy of the recorded gaze position and the amount of data loss, deteriorates (compared to well-trained participants in chinrests) when the participant is unrestrained and assumes a non-optimal pose in front of the eye-tracker. How then can researchers working with unrestrained participants choose an eye-tracker? Here we investigated the performance of five popular remote eye-trackers from EyeTribe, SMI, SR Research, and Tobii in a series of tasks where participants took on non-optimal poses. We report that the tested systems varied in the amount of data loss and systematic offsets observed during our tasks. The EyeLink and EyeTribe in particular had large problems. Furthermore, the Tobii eye-trackers reported data for two eyes when only one eye was visible to the eye-tracker. This study provides practical insight into how popular remote eye-trackers perform when recording from unrestrained participants. It furthermore provides a testing method for evaluating whether a tracker is suitable for studying a certain target population, and that manufacturers can use during the development of new eye-trackers.
How is semantic information stored in the human mind and brain? Some philosophers and cognitive scientists argue for vectorial representations of concepts, where the meaning of a word is represented as its position in a high-dimensional neural state space. At the intersection of natural language processing and artificial intelligence, a class of very successful distributional word vector models has developed that can account for classic EEG findings of language, that is, the ease versus difficulty of integrating a word with its sentence context. However, models of semantics have to account not only for context-based word processing, but should also describe how word meaning is represented. Here, we investigate whether distributional vector representations of word meaning can model brain activity induced by words presented without context. Using EEG activity (event-related brain potentials) collected while participants in two experiments (English and German) read isolated words, we encoded and decoded word vectors taken from the family of prediction-based Word2vec algorithms. We found that, first, the position of a word in vector space allows the prediction of the pattern of corresponding neural activity over time, in particular during a time window of 300 to 500 ms after word onset. Second, distributional models perform better than a human-created taxonomic baseline model (WordNet), and this holds for several distinct vector-based models. Third, multiple latent semantic dimensions of word meaning can be decoded from brain activity. Combined, these results suggest that empiricist, prediction-based vectorial representations of meaning are a viable candidate for the representational architecture of human semantic knowledge.
Background: Depression is a widespread disorder with severe impacts for individuals and society, especially in its chronic form. Current treatment approaches for persistent depression have focused primarily on reducing negative affect and have paid little attention to promoting positive affect. Previous studies have shown that metta meditation increases positive affect in chronically depressed patients. Results from previous trials provide evidence for the efficacy of a stand-alone metta meditation group treatment in combination with mindfulness-based approaches. Further research is needed to better understand the implementation of meditation practice into everyday life. Therefore, mindfulness and metta meditation in a group setting are combined with individual cognitive behavioral therapy (CBT) into a new, low-intensity, cost-effective treatment (“MeCBT”) for chronic depression. Methods/design: In this single-center, randomized, observer-blinded, parallel-group clinical trial we will test the efficacy of MeCBT in reducing depression compared to a wait-list control condition. Forty-eight participants in a balanced design will be allocated randomly to a treatment group or a wait-list control group. Metta-based group meditation will be offered in eight weekly sessions and one additional half-day retreat. Subsequent individual CBT will be conducted in eight fortnightly sessions. Outcome measures will be assessed at four time points: before intervention (T0); after group meditation (T1); after individual CBT (T2); and, in the treated group only, at 6-month follow-up (T3). Changes in depressive symptoms (clinician rating), assessed with the Quick Inventory of Depressive Symptoms (QIDS-C) are the primary outcome. We expect a significant decline of depressive symptoms at T2 compared to the wait-list control group. Secondary outcome measures include self-rated depression, mindfulness, benevolence, rumination, emotion regulation, social connectedness, social functioning, as well as behavioral and cognitive avoidance. We will explore changes at T1 and T2 in all these secondary outcome variables. Discussion: To our knowledge this is the first study to combine a group program focusing on Metta meditation with stateof-the art individual CBT specifically tailored to chronic depression. Implications for further refinement and examination of the treatment program are discussed. Trial registration: ISRCTN, ISRCTN97264476.

Background: While the efficacy of cognitive therapy (CT) has been well established for social anxiety disorder (SAD) in several randomized controlled trials, there are still large differences between trials with respect to effect sizes. The present study investigates the question of whether enhanced training and the use of behavioral experiments (BEs) increases the efficacy of traditional CT, based on verbal methods of cognitive restructuring. Methods/design: A mixed within/between conditions design will be applied, with therapists and patients being randomly allocated to one of two conditions: (1) training of CT plus BEs, (2) training of CT “as usual”. Sixty patients with the primary diagnosis of SAD will be recruited and treated in the outpatient clinic of the Department of Psychology, University of Frankfurt. To ensure adherence to therapist protocols, all therapists will be trained and supervised by the project coordinators. In addition, videotaped treatment sessions will be independently evaluated to guarantee both adherence to protocols and the quality of the intervention. Treatment effects will be assessed by independent SAD symptom ratings using the Liebowitz Social Anxiety Scale as the primary outcome measure and self-report measures as secondary outcome measures. Discussion: The present cognitive behavioral therapy (CBT) trial will be the first to clarify the contribution of BEs to the efficacy of CT in a randomized controlled design. Study results are relevant to clinical training and implementation of evidence-based treatments.

Children with reading and/or spelling disorders have increased rates of behavioral and emotional problems and combinations of these. Some studies also find increased rates of attention-deficit/hyperactivity disorder (ADHD), conduct disorder, anxiety disorder, and depression. However, the comorbidities of, e.g., arithmetic disorders with ADHD, anxiety disorder, and depression have been addressed only rarely. The current study explored the probability of children with specific learning disorders (SLD) in reading, spelling, and/or arithmetic to also have anxiety disorder, depression, ADHD, and/or conduct disorder. The sample consisted of 3,014 German children from grades 3 and 4 (mean age 9;9 years) who completed tests assessing reading, spelling as well as arithmetic achievement and intelligence via a web-based application. Psychopathology was assessed using questionnaires filled in by the parents. In children with a SLD we found high rates of anxiety disorder (21%), depression (28%), ADHD (28%), and conduct disorder (22%). Children with SLD in multiple learning domains had a higher risk for psychopathology and had a broader spectrum of psychopathology than children with an isolated SLD. The results highlight the importance of screening for and diagnosing psychiatric comorbidities in children with SLD.
Cognitive modeling studies in adults have established that visual working memory (WM) capacity depends on the representational precision, as well as its variability from moment to moment. By contrast, visuospatial WM performance in children has been typically indexed by response accuracy—a binary measure that provides less information about precision with which items are stored. Here, we aimed at identifying whether and how children’s WM performance depends on the spatial precision and its variability over time in real-world contexts. Using smartphones, 110 Grade 3 and Grade 4 students performed a spatial WM updating task three times a day in school and at home for four weeks. Measures of spatial precision (i.e., Euclidean distance between presented and reported location) were used for hierarchical modeling to estimate variability of spatial precision across different time scales. Results demonstrated considerable within-person variability in spatial precision across items within trials, from trial to trial and from occasion to occasion within days and from day to day. In particular, item-to-item variability was systematically increased with memory load and lowered with higher grade. Further, children with higher precision variability across items scored lower in measures of fluid intelligence. These findings emphasize the important role of transient changes in spatial precision for the development of WM.
As a relevant cognitive-motivational aspect of ICT literacy, a new construct ICT Engagement is theoretically based on self-determination theory and involves the factors ICT interest, Perceived ICT competence, Perceived autonomy related to ICT use, and ICT as a topic in social interaction. In this manuscript, we present different sources of validity supporting the construct interpretation of test scores in the ICT Engagement scale, which was used in PISA 2015. Specifically, we investigated the internal structure by dimensional analyses and investigated the relation of ICT Engagement aspects to other variables. The analyses are based on public data from PISA 2015 main study from Switzerland (n = 5860) and Germany (n = 6504). First, we could confirm the four-dimensional structure of ICT Engagement for the Swiss sample using a structural equation modelling approach. Second, ICT Engagement scales explained the highest amount of variance in ICT Use for Entertainment, followed by Practical use. Third, we found significantly lower values for girls in all ICT Engagement scales except ICT Interest. Fourth, we found a small negative correlation between the scores in the subscale “ICT as a topic in social interaction” and reading performance in PISA 2015. We could replicate most results for the German sample. Overall, the obtained results support the construct interpretation of the four ICT Engagement subscales.
Based on a meta-analysis, Redick and Lindsey (2013) found that complex span and n-back tasks show an average correlation of r = 0.20, and concluded that "complex span and n-back tasks cannot be used interchangeably as working memory measures in research applications" (p. 1102). Here, we comment on this conclusion from a psychometric perspective. In addition to construct variance, performance on a test contains measurement error, task-specific variance, and paradigm-specific variance. Hence, low correlations among dissimilar indicators do not provide strong evidence for the existence, or absence, of a construct common to both indicators. One way to arrive at such evidence is to fit hierarchical latent factors that model task-specific, paradigm-specific, and construct variance. We report analyses for 101 younger and 103 older adults who worked on nine different working memory tasks. The data are consistent with a hierarchical model of working memory, according to which both complex span and n-back tasks are valid indicators of working memory. The working memory factor predicts 71% of the variance in a factor of reasoning among younger adults (83% for among older adults). When the working memory factor was restricted to any possible triplet of working memory tasks, the correlation between working memory and reasoning was inversely related to the average magnitude of the correlations among the indicators, indicating that more highly intercorrelated indicators may provide poorer coverage of the construct space. We stress the need to go beyond specific tasks and paradigms when studying higher-order cognitive constructs, such as working memory.
Imageability and emotionality ratings for 2592 German nouns (3–10 letters, one to three phonological syllables) were obtained from younger adults (21–31 years) and older adults (70–86 years). Valid ratings were obtained on average from 20 younger and 23 older adults per word for imageability, and from 18 younger and 19 older adults per word for emotionality. The internal consistency (Cronbach’s α) and retest rank-order stability of the ratings were high for both age groups (α and r ≥ .97). Also, the validity of our ratings was found to be high, as compared to previously published ratings (r ≥ .86). The ratings showed substantial rank-order stability across younger and older adults (imageability, r = .94; emotionality, r = .85). At the same time, systematic differences between age groups were found in the mean levels of ratings (imageability, d = 0.38; emotionality, d = 0.20) and in the extent to which the rating scales were used (imageability, SD = 24 vs. 19, scale of 0 to 100; emotionality, SD = 26 vs. 31, scale of −100 to 100). At the descriptive level, our data hint at systematically different evaluations of semantic categories regarding imageability and emotionality across younger and older adults. Given that imageability and emotionality have been reported, for instance, as important determinants for the recognition and recall of words, our findings highlight the importance of considering age-specific information in age-comparative cognitive (neuroscience) experimental studies using word materials. The age-specific imageability and emotionality ratings for the 2592 German nouns can be found in the electronic supplementary material...
Ergodic subspace analysis
(2020)
Properties of psychological variables at the mean or variance level can differ between persons and within persons across multiple time points. For example, cross-sectional findings between persons of different ages do not necessarily reflect the development of a single person over time. Recently, there has been an increased interest in the difference between covariance structures, expressed by covariance matrices, that evolve between persons and within a single person over multiple time points. If these structures are identical at the population level, the structure is called ergodic. However, recent data confirms that ergodicity is not generally given, particularly not for cognitive variables. For example, the <i>g</i> factor that is dominant for cognitive abilities between persons seems to explain far less variance when concentrating on a single person’s data. However, other subdimensions of cognitive abilities seem to appear both between and within persons; that is, there seems to be a lower-dimensional subspace of cognitive abilities in which cognitive abilities are in fact ergodic. In this article, we present ergodic subspace analysis (ESA), a mathematical method to identify, for a given set of variables, which subspace is most important within persons, which is most important between person, and which is ergodic. Similar to the common spatial patterns method, the ESA method first whitens a joint distribution from both the between and the within variance structure and then performs a principle component analysis (PCA) on the between distribution, which then automatically acts as an inverse PCA on the within distribution. The difference of the eigenvalues allows a separation of the rotated dimensions into the three subspaces corresponding to within, between, and ergodic substructures. We apply the method to simulated data and to data from the COGITO study to exemplify its usage.
In this paper, we developed a method to extract item-level response times from log data that are available in computer-based assessments (CBA) and paper-based assessments (PBA) with digital pens. Based on response times that were extracted using only time differences between responses, we used the bivariate generalized linear IRT model framework (B-GLIRT, [1]) to investigate response times as indicators for response processes. A parameterization that includes an interaction between the latent speed factor and the latent ability factor in the cross-relation function was found to fit the data best in CBA and PBA. Data were collected with a within-subject design in a national add-on study to PISA 2012 administering two clusters of PISA 2009 reading units. After investigating the invariance of the measurement models for ability and speed between boys and girls, we found the expected gender effect in reading ability to coincide with a gender effect in speed in CBA. Taking this result as indication for the validity of the time measures extracted from time differences between responses, we analyzed the PBA data and found the same gender effects for ability and speed. Analyzing PBA and CBA data together we identified the ability mode effect as the latent difference between reading measured in CBA and PBA. Similar to the gender effect the mode effect in ability was observed together with a difference in the latent speed between modes. However, while the relationship between speed and ability is identical for boys and girls we found hints for mode differences in the estimated parameters of the cross-relation function used in the B-GLIRT model.
Early experiences of childhood sexual or physical abuse are often associated with functional impairments, reduced well-being and interpersonal problems in adulthood. Prior studies have addressed whether the traumatic experience itself or adult psychopathology is linked to these limitations. To approach this question, individuals with posttraumatic stress disorder (PTSD) and healthy individuals with and without a history of child abuse were investigated. We used global positioning system (GPS) tracking to study temporal and spatial limitations in the participants’ real-life activity space over the course of one week. The sample consisted of 228 female participants: 150 women with PTSD and emotional instability with a history of child abuse, 35 mentally healthy women with a history of child abuse (healthy trauma controls, HTC) and 43 mentally healthy women without any traumatic experiences in their past (healthy controls, HC). Both traumatized groups—i.e. the PTSD and the HTC group—had smaller movement radii than the HC group on the weekends, but neither spent significantly less time away from home than HC. Some differences between PTSD and HC in movement radius seem to be related to correlates of PTSD psychopathology, like depression and physical health. Yet group differences between HTC and HC in movement radius remained even when contextual and individual health variables were included in the model, indicating specific effects of traumatic experiences on activity space. Experiences of child abuse could limit activity space later in life, regardless of whether PTSD develops.
How does social class affect people’s goals in social interactions? A rank-based perspective suggests actors from higher social classes (compared to lower social classes) have more agentic and less communal goals when interacting with same class or unspecified others. Focusing on targets’ social class, an identity-based perspective suggests the reverse: Actors should more strongly endorse communal (agentic) goals toward illegitimately lower class (higher class) compared to illegitimately higher class (lower class) targets, regardless of actors’ own social class. Three preregistered experiments (N = 2,023) manipulated actor’s social class and the nature of the target (illegitimately higher/lower class, same class, unspecified) and measured participants’ goals in imagined interactions using the Circumplex Scales of Intergroup Goals. The identity-based perspective received strong support: Across studies, actors expressed stronger agentic (communal) goals toward higher class (lower class) targets. The rank-based perspective received limited support, with relatively low-class (vs. relatively high-class) actors expressing stronger communal goals toward same-class targets.
The purpose of this study was to examine the psychometric properties (i.e., factorial validity, measurement invariance, and reliability) of the Grit-Original scale (Grit-O) within the Netherlands. The Grit-O scale was subjected to a competing measurement modeling strategy that sequentially compared both independent cluster model confirmatory factor analytical- and exploratory structural equation modeling approaches. The results showed that both a two first order, bi-factor structure as well as a less restrictive two factor ESEM factorial structure best-fitted the data. The instrument showed to be reliable at both a lower- (Cronbach’s alpha) and upper-level (composite reliability) limit. However, measurement invariance between genders could only be established for the B-ICM-CFA model. Finally, concurrent validity was established through relating the GRIT-O to task performance. The linear use of the Grit-O scale should therefore carefully be considered.
Despite the popularity of the term Positive Psychological Coaching within the literature, there is no consensus as to how it should be defined (framed) or what the components of a positive coaching “model” should include. The aim of this systematic review was to define positive psychological coaching and to construct a clear demarcated positive psychological coaching model based on the literature. A systematic literature review led to the extraction of 2,252 records. All records were screened using specific inclusion/exclusion criteria, which resulted in the exclusion of records based on duplicates (n = 1,232), titles (n = 895), abstracts (n = 78), and criteria violations (n = 23). Twenty-four academic, peer-reviewed publications on positive psychological coaching were included. Data relating to conceptual definitions and coaching models/phases/frameworks were extracted and processed through thematic content analysis. Our results indicate that positive psychological coaching can be defined as a short to medium term professional, collaborative relationship between a client and coach, aimed at the identification, utilization, optimization, and development of personal strengths and resources in order to enhance positive states, traits and behaviors. Utilizing Socratic goal setting and positive psychological evidence-based approaches to facilitate personal growth, optimal functioning, enhanced wellbeing, and the actualization of people's potential. Further, eight critical components of a positive psychological coaching model were identified and discussed. The definition and coaching process identified in this study will provide coaches with a fundamental positive psychological framework for optimizing people's potential.
Attachment theory is commonly used to investigate children’s psychosocial development. To demonstrate cultural variability and to advance the idea of attachment as a collective resource, we assessed children’s attachment networks during middle childhood among the Nseh, a Cameroonian clan with distinct concepts of family and childhood. Using photo elicitation interviews, we used an exploratory approach to investigate the structural and functional composition of these networks and to generate a comprehensive overview. Participants were 11 children (six girls and five boys), aged 6 to 10 years. Children took photos of individuals who were important to them and with whom they felt safe, comfortable, and at ease. Then, in follow-up interviews they were asked to characterize their attachment figures on sociostructural dimensions and to elaborate how those individuals made them feel comfortable and safe. Transcripts of the interviews were coded using ethnographic strategies. Initial descriptive codes were analyzed concerning key terms, semantic relationships, and their context of meaning, before assigning higher level codes to generate distinct main categories of functionality. Children described attachment networks that were structurally adapted to concepts of social ties and interactional norms of the clan. Concerning their functionality, children differentiated between peers, responsible for overt emotional needs, and adults, providing nutritional care. We conclude that this pattern reflects sources of security and concepts of care of the distinct developmental environment. We discuss the importance of context-specific and comprehensive approaches to attachment, moving beyond Eurocentric monotropic concepts, with the goal of developing a complex understanding of childhood across ecocultural settings.
Problematisation: In recent years, psychology has been going through a crisis of sorts. Research methods and practices have come under increased scrutiny, with many issues identified as negatively contributing to low replicability and reproducibility of psychological research.
Implications: As a consequence, researchers are increasingly called upon to overhaul and improve their research process. Various stakeholders within the scientific community are arguing for more openness and rigor within industrial and organisational (I-O) psychological research. A lack of transparency and openness further fuels criticisms as to the credibility and trustworthiness of I-O psychology which negatively affects the evidence-based practices which it supports. Furthermore, traditional gate-keepers such as grant agencies, professional societies and journals, are adapting their policies, reflecting an effort to curtail these trends.
Purpose: The purpose of this opinion paper is, therefore, to stimulate an open dialogue with the South African Journal of Industrial Psychology (SAJIP) contributing authors, its editorial board and readership about the challenges associated with the replication crisis in psychology. Furthermore, it attempts to discuss how the identified issues affect I-O psychology and how these could be managed through open science practices and other structural improvements within the SAJIP.
Recommendations: We enumerate several easily implementable open science practices, methodological improvements and editorial policy enhancements to enhance credibility and transparency within the SAJIP. Relying on these, we recommend changes to the current practices that can be taken up by researchers and the SAJIP to improve reproducibility and replicability in I-O psychological science.
Problematisation: The credibility and transparency of industrial and organisational psychological (IOP) research within South Africa was recently challenged by Efendic and Van Zyl (2019). The authors briefly showed inconsistencies in statistical results reported by authors of the South African Journal of Industrial Psychology (SAJIP), that various studies were insufficiently powered, that best-practice guidelines for the reporting of results were mostly only partially followed and that no transparency exists with regard to the research process. They demonstrated that authors of the SAJIP may knowingly or unknowingly be engaging in questionable research practices, which directly affects the credibility of both the discipline and the journal. Furthermore, they suggested practical guidelines for both authors and the SAJIP on how this could be managed.
Implications: Based on these suggestions, the authors invited prominent members of the IOP scientific community to provide scholarly commentary on their paper in order to aid in the development of ‘a clear strategy on how [the confidence crisis in IOP] could be managed, what the role of SAJIP is in this process and how SAJIP and its contributors could proactively engage to address these issues’. Seven members of the editorial board and two international scholars provided commentaries in an attempt to further the debate about the nature, causes, consequences and management of the credibility crisis within the South African context.
Purpose: The purpose of this final rebuttal article was to summarise and critically reflect on the commentaries of the nine articles to advance the debate on the confidence crisis within the South African IOP discipline.
Recommendations: All SAJIP’s stakeholders (authors, editors, reviewers, the publication house, universities and the journal) can play an active role in enhancing the credibility of the discipline. It is suggested that SAJIP should develop a clear and structured strategy to promote credible, transparent and ethical research practices within South Africa.
Orientation: The purpose of this editorial was to provide an introduction and a general overview of the special issue on Open Science Practices: A Vision for the Future of SAJIP, as hosted in the 45th edition of the South African Journal of Industrial Psychology (SAJIP). Specifically, the aim was to provide a viable, practical and implementable strategy for enhancing the scientific credibility, transparency and international stature of SAJIP.
With increasing importance of organizational effectivity and efficiency measures like Balanced Scorecard and optimization of employee work behavior to achieve higher organizational efficiency, Human Resource activities concerning leadership development and academic leadership research are growing. Throughout the course of the twentieth century, a multitude of empirical studies show primarily positive relationships between different constructs of leadership models and desirable variables of organizational behavior. It becomes apparent, though, that in academic research the selection of analyzed leadership models and their consequences is very heterogeneous. This Master Thesis has the objective to contribute to Leadership Research by applying a comparative empirical study in the–until today–often neglected study population of in-house and sales personnel within the pharmaceutical industry. For this purpose, an online employee survey with N = 137 participants from a leading pharmaceutical company in Germany was conducted. Based on contemporary leadership theory, a range of Hypotheses regarding consequences of modern leadership models is empirically tested. The results of the study reconfirm Identification with Manager, Trust & Loyalty and Employee Satisfaction as consequences of Authentic as well as Transformational leadership. Work context as in-house vs. sales setting shows moderating effects on some of the leadership-consequences relationships. As the research involves multiple structurally different variables as well as constructs and compares feedback of different study populations, tangible management implications to boost desirable work attitudes and behaviors can be derived and appropriately adapted to match the respective work context. Ramifications for future scientific research are also presented.
In diesem Beitrag wird ein hochschuldidaktisches Konzept zur Förderung des reflektierten Umgangs mit Heterogenität im schulischen Kontext unter Verwendung digitaler Lerneinheiten vorgestellt. Im Projekt "Level – Lehrkräftebildung vernetzt entwickeln" (Qualitätsoffensive Lehrerbildung BMBF, Goethe-Universität Frankfurt) wurden in den Bildungswissenschaften digitale Lerneinheiten zu den Heterogenitätsdimensionen "Geschlecht", "kultureller Hintergrund", "sozio-ökonomischer Hintergrund", "kognitiv-motivationale Lernvor-aussetzungen" und "Behinderung" konzipiert und in der universitären Lehre erprobt. Die Auswahl der erstellten Lerneinheiten begründet sich auf Ergebnissen der PISA-Studien sowie der UN-Behindertenrechtskonvention. Die Lerneinheiten werden in Blended-Learning-Szenarien eingesetzt und zielen auf den Aufbau von Fachwissen und professionellen Überzeugungen sowie Reflexivität. Auf der Grundlage individuellen Vorwissens werden von den Lernenden (videobasierte) Aufgaben bearbeitet, die der Perspektivübernahme und Selbstreflexion im Hinblick auf Kategorisierungen dienen und die Bearbeitung fachwissenschaftlicher Texte und aktueller Studien beinhalten.

Im Zuge der Modernisierung haben die religiösen Erzählungen ihre Einheit stiftende Kraft verloren. An ihre Stelle ist die menschliche Vernunft getreten und mit ihr die Logik eines rationalen, ganz auf Fortschritt ausgerichtetes Handelns, während Beziehungserfahrungen und mit ihr der unverzichtbare Wunsch nach Resonanz immer stärker in den Hintergrund treten. Menschen lassen sich auf Dauer aber nicht allein mit effizienzorientierten Rückmeldungen abspeisen. Sie warten auf Anerkennung, die von außen kommt; sie warten auf Resonanz. Hartmut Rosa hat die Vorstellung von einem Verstummen der Welt, in der der verzweifelte Ruf nach dem Anderen keine Antwort mehr findet, nicht umsonst als die tiefste Angst bezeichnet, der die Menschen heute umtreibt. Die Autorin beschreibt vor diesem Hintergrund die Erfahrung von Resonanz als menschliches Grundbedürfnis und zeigt als erstes an Beispielen aus der Literatur, wie diese sich dort in außergewöhnlichen Naturerlebnissen, in der Selbstentgrenzung von Liebesbeziehungen und in der präreflexiven Erfahrung Gottes, die keiner weiteren Begründung mehr bedarf, erfahrbar wird. Anschließend wendet sie sich Resonanzerfahrungen im Bereich der Psychoanalyse zu. Im letzten Abschnitt ihrer Arbeit befasst sie sich mit Resonanzerfahrungen in der pluralistischen Gesellschaft, in der es unterschiedliche Sinndeutungen gibt, die gleichermaßen legitim sind und nach Anerkennung verlangen.
Despite common notion that the correlation of socioeconomic status with child cognitive performance may be driven by both environmentally- and genetically-mediated transactional pathways, there is a lack of longitudinal and genetically informed research that examines these postulated associations. The present study addresses whether family income predicts associative memory growth and hippocampal development in middle childhood and tests whether these associations persist when controlling for DNA-based polygenic scores of educational attainment. Participants were 142 6-to-7-year-old children, of which 127 returned when they were 8-to-9 years old. Longitudinal analyses indicated that the association of family income with children's memory performance and hippocampal volume remained stable over this age range and did not predict change. On average, children from economically disadvantaged background showed lower memory performance and had a smaller hippocampal volume. There was no evidence to suggest that differences in memory performance were mediated by differences in hippocampal volume. Further exploratory results suggested that the relationship of income with hippocampal volume and memory in middle childhood is not primarily driven by genetic variance captured by polygenic scores of educational attainment, despite the fact that polygenic scores significantly predicted family income.
With every glimpse of our eyes, we sample only a small and incomplete fragment of the visual world, which needs to be contextualized and integrated into a coherent scene representation. Here we show that the visual system achieves this contextualization by exploiting spatial schemata, that is our knowledge about the composition of natural scenes. We measured fMRI and EEG responses to incomplete scene fragments and used representational similarity analysis to reconstruct their cortical representations in space and time. We observed a sorting of representations according to the fragments' place within the scene schema, which occurred during perceptual analysis in the occipital place area and within the first 200 ms of vision. This schema-based coding operates flexibly across visual features (as measured by a deep neural network model) and different types of environments (indoor and outdoor scenes). This flexibility highlights the mechanism's ability to efficiently organize incoming information under dynamic real-world conditions.
Previous reports of improved oral reading performance for dyslexic children but not for regular readers when between-letter spacing was enlarged led to the proposal of a dyslexia-specific deficit in visual crowding. However, it is in this context also critical to understand how letter spacing affects visual word recognition and reading in unimpaired readers. Adopting an individual differences approach, the present study, accordingly, examined whether wider letter spacing improves reading performance also for non-impaired adults during silent reading and whether there is an association between letter spacing and crowding sensitivity. We report eye movement data of 24 German students who silently read texts presented either with normal or wider letter spacing. Foveal and parafoveal crowding sensitivity were estimated using two independent tests. Wider spacing reduced first fixation durations, gaze durations, and total fixation time for all participants, with slower readers showing stronger effects. However, wider letter spacing also reduced skipping probabilities and elicited more fixations, especially for faster readers. In terms of words read per minute, wider letter spacing did not provide a benefit, and faster readers in particular were slowed down. Neither foveal nor parafoveal crowding sensitivity correlated with the observed letter-spacing effects. In conclusion, wide letter spacing reduces single word processing time in typically developed readers during silent reading, but affects reading rates negatively since more words must be fixated. We tentatively propose that wider letter spacing reinforces serial letter processing in slower readers, but disrupts parallel processing of letter chunks in faster readers. These effects of letter spacing do not seem to be mediated by individual differences in crowding sensitivity.
Background: Prolonged grief disorder (PGD) will be newly included in the ICD-11, while a clinically similar diagnosis, persistent complex bereavement disorder (PCBD), has already been added to the DSM-5. Only few studies have evaluated these criteria-sets for prolonged grief.
Objective: The aim of this study was to evaluate the ICD-11 accessory symptom threshold and compare the diagnostic performance of the two criteria-sets in treatment-seeking bereaved persons.
Method: 113 grief treatment-seeking bereaved persons completed the Interview for Prolonged Grief-13. We used receiver operator characteristic analysis to determine an optimum ICD-11 accessory symptom threshold. We calculated diagnostic rates for PGD and PCBD and examined associations of PGD and PCBD caseness with concurrently assessed psychopathology and prolonged grief symptoms assessed one month later.
Results: An ICD-11 threshold of six accessory symptoms distinguished optimally between interview-diagnosed participants with and without prolonged grief. The prevalence of PGD (69%) was significantly higher than that of PCBD (48%) and of PGD with a 6-symptom threshold (47%). PGD caseness was associated with the relation to the deceased, 6-symptom threshold PGD and PCBD caseness with the time since loss. All criteria-sets were linked to concurrent prolonged grief, depression, and general mental distress. PCBD and 6-symptom threshold PGD but not PGD were associated with prolonged grief severity one month later.
Conclusions: The results support the validity of PGD and PCBD but, at the same time, they provide further support for differing prevalence rates. Using an empirically determined ICD-11 accessory symptom threshold could prevent the pathologisation of grief reactions.
Wir konnten unseren eigenen Weg gehen, jeder von uns hatte am Ende ein anderes Ergebnis und es war keines falsch. Das macht für mich die Qualität beim Lernen aus, dass mir genug Platz für meine Gedanken gegeben wird und ich ernst genommen werde. […] Dieses Gefühl ist bis heute nicht verloren gegangen und der Gedanke, wie es sein könnte, hilft mir, aus mir raus zukommen und andere zu motivieren, das ebenfalls zu tun, um auch um mich herum anregende Gespräche zu führen, die an die während der Akademie geführten heranreichen. (Feedback einer Teilnehmerin der HSAKA-M 2018)
Bildung durch Wissenschaft im Sinne des Forschenden Lernens ist ein zentrales Thema schulischer Bildung und findet beispielsweise im Konzept Kultur.Forscher! eine didaktische, schulische Umsetzung und wird vom Wissenschaftsrat als Leitgedanke ebenfalls für Universitäten mit dem Ziel empfohlen, Studium und Lehre deutlicher an der Forschung auszurichten.
Die Erfahrung, "…dass alles auch ganz anders sein könnte" ist die wohl wichtigste Erfahrung in Bildungsprozessen. Die Entdeckung von Möglichkeiten, Perspektivwechseln und transformatorischen Selbst-Bildungsprozessen ist zentral für eine gelungene kulturelle Bildungssituation. (Birgit Mandel, 2005).
Die Hessischen Schülerakademien zur Förderung besonders engagierter und begabter junger Menschen wurden bewusst als ein Unterfangen des Forschenden Lernens gegründet und fühlen sich diesem Leitgedanken im Kontext kultureller Bildung verpflichtet. Dieser Satz klingt zunächst einmal gut und zeitgemäß. Doch was steckt genau dahinter?
Das Zusammentreffen zu Beginn der Sommerferien von 60 wissbegierigen und experimentierfreudigen Schülerinnen und Schülern mit einem ebensolchen Team aus Hochschullehrenden und Kulturschaffenden, versprach wie immer eine intensive und aufregende Zeit zu werden. Diese positive Erwartung wurde auch voll erfüllt und gipfelte am Gästenachmittag mit Eltern, Verwandten, Freunden und interessierten Besuchern in einen feierlich-fröhlichen Abschluss mit spannenden und auch überraschenden Werkschauen der Kurse. Ein besonderes Highlight war die großformatige Gestaltung eines Modells der BURG FÜRSTENECK als interdisziplinäres Ergebnis des Hauptkurses Mathematik und des Wahlkurses Modellbau.
Background: Research on desired emotions revealed that individuals want to feel negative emotions if they expect these emotions to yield certain benefits. In previous studies, the pursuit of sadness (e.g., via pursuing art that evokes sadness) has been attributed to hedonic motives, i.e., to feel pleasure. We propose that in individuals with major depressive disorder (MDD) the pursuit of sadness may be more strongly related to self-verification motives, i.e., to sustain their sense of self through feeling sad.
Methods: Participants with MDD (n = 50) were compared to non-depressed controls (n = 50) in their desired emotional states, as indicated by selected music (sad, happy and neutral), and in their motives (hedonic vs. self-verification) for choosing sad music. Groups were also compared in their self-reported general preference for sadness and the perceived functionality of sadness.
Results: MDD participants showed a significant higher desire for sadness; more than half of them deliberately chose sad music. Whereas MDD participants had a marked preference for self-verification over hedonic motives, the reverse was true for non-depressed controls. MDD participants also agreed more strongly with self-verifying functions of sadness and expressed a stronger general preference for sadness.
Conclusion: Findings indicate that emotion regulation in MDD might be driven by self-verification motives. They point to the relevance of exploring patients’ desired emotional states and associated motives. The systematic integration of positive affect into the self-image of depressed patients might help to deemphasize the self-verifying function of sadness, thereby overcoming the depression.
Based on neurofeedback (NF) training as a neurocognitive treatment in attention-deficit/hyperactivity disorder (ADHD), we designed a randomized, controlled functional near-infrared spectroscopy (fNIRS) NF intervention embedded in an immersive virtual reality classroom in which participants learned to control overhead lighting with their dorsolateral prefrontal brain activation. We tested the efficacy of the intervention on healthy adults displaying high impulsivity as a sub-clinical population sharing common features with ADHD. Twenty participants, 10 in an experimental and 10 in a shoulder muscle-based electromyography control group, underwent eight training sessions across 2 weeks. Training was bookended by a pre- and post-test including go/no-go, n-back, and stop-signal tasks (SST). Results indicated a significant reduction in commission errors on the no-go task with a simultaneous increase in prefrontal oxygenated hemoglobin concentration for the experimental group, but not for the control group. Furthermore, the ability of the subjects to gain control over the feedback parameter correlated strongly with the reduction in commission errors for the experimental, but not for the control group, indicating the potential importance of learning feedback control in moderating behavioral outcomes. In addition, participants of the fNIRS group showed a reduction in reaction time variability on the SST. Results indicate a clear effect of our NF intervention in reducing impulsive behavior possibly via a strengthening of frontal lobe functioning. Virtual reality additions to conventional NF may be one way to improve the ecological validity and symptom-relevance of the training situation, hence positively affecting transfer of acquired skills to real life.
Die vorliegende Arbeit befasst sich mit der Entwicklung und Validierung eines Messinstrumentes zur Erfassung von psychopathischen Persönlichkeitseigenschaften, dem Fragebogen Psychopathischer Persönlichkeitseigenschaften (FPP), mit der Entwicklung eines Messinstrumentes, das antisoziales Verhalten und Kriminalität getrennt erfasst, der Checkliste für antisoziale Verhaltensweisen und Kriminalität (CAV/K) und mit der differenzierten Untersuchung der Vorhersage von Kriminalität durch psychopathische Eigenschaften.
Psychopathie ist eines der wichtigsten Konstrukte in der Vorhersage von kriminellem und antisozialem Verhalten (Hemphill, Hare & Wong, 1998). Die Konzeption der psychopathischen Persönlichkeit stellt affektive und interpersonelle Eigenschaften in den Vordergrund und definiert Kriminalität als Konsequenz statt Kernsymptom der Psychopathie (Skeem & Cooke, 2010a). Bisherige Ergebnisse zur prädiktiven Validität von psychopathischen Eigenschaften hinsichtlich krimineller Rückfälligkeit weisen allerdings darauf hin, dass affektive und interpersonelle Facetten der Psychopathie keinen Erklärungswert über eine kriminelle Vorgeschichte hinaus haben (Eher, Schilling, Mönichweger, Haubner-MacLean & Rettenberger, 2012; Walters, Knight, Grann & Dahle, 2008; Walters, Wilson & Glover, 2011). Des Weiteren wird im Rahmen der adaptiven Psychopathie postuliert, dass psychopathische Eigenschaften auch hoch ausgeprägt sein können, ohne dass sich die Personen kriminell verhalten (Hall & Benning, 2006). Ergebnisse aus einer Metananalyse eines etablierten Fragebogens zur Psychopathie, dem Psychopathic Personality Inventory (PPI; Lilienfeld & Andrews, 1996) ergaben, dass der erste von zwei Faktoren nicht mit Indizes antisozialer Verhaltensweisen korrelieren. Diese Ergebnisse sprechen dafür, dass der Zusammenhang zwischen Psychopathie und Kriminalität genauer untersucht werden muss, da ein Fehlen dieser Assoziation das Konstrukt Psychopathie obsolet erscheinen lässt.
Voraussetzung für die valide Untersuchung dieses Zusammenhangs ist die Verfügbarkeit von psychometrisch hochwertigen und validen Instrumenten zur Erfassung der Variablen. Die Erfassung von psychopathischen Eigenschaften im Selbstbericht ist ökonomisch und Beurteilungen fallen valide aus (Ray et al., 2013). Der Fragebogen PPI (Lilienfeld & Andrews, 1996) ist bereits gut etabliert, weist jedoch einige methodische Schwächen auf, wie z. B. eine Vielzahl von Items sowie eine schwer replizierbare Faktorenstruktur.
Deshalb wurde im ersten Schritt der Fragebogen Psychopathischer Persönlichkeitseigenschaften (FPP, Etzler & Rohrmann, 2017a, 2017b) entwickelt, der die Kritikpunkte des PPI überwindet und psychopathische Persönlichkeitseigenschaften mit hoher psychometrischer Gute misst. Der FPP erfasst sechs Facetten der Psychopathie, die theoretisch hergeleitet wurden: Fehlende Empathie, Furchtlosigkeit, Narzisstischer Egozentrismus, Impulsivität, Soziale Manipulation und Macht. Diese Facetten unterscheiden sich bis auf Furchtlosigkeit von den Skalen des PPI. Die Items sind kurz und inhaftierungsadäquat formuliert und weisen eine mittlere Situationsspezifität auf. Die Itemselektion basierte auf einer Stichprobe von n = 173 Straftätern und n = 132 Zivilpersonen, was repräsentativ für den Anwendungsbereich des FPP ist. Ergebnisse weisen auf gute psychometrische Eigenschaften, wie Itemkennwerte und Reliabilität (ω = .85) hin, auf überwiegend gleiche Messeigenschaften in Zivil- und Haftstichprobe sowie auf eine Konvergenz mit dem PPI (r = .677∗∗) in erwarteter Höhe. Erwartungskonforme Zusammenhänge mit weiteren Konstrukten, Korrelationen mit antisozialem Verhalten, Disziplinarmaßnahmen in Haft und Inhaftierung selbst unterstützen die Kriteriumsvalidität des FPP.
Die Vorhersage von Kriminalität setzt des Weiteren eine präzise Definition ebendieser Variable voraus. Allerdings wurde Kriminalität bis dato in den publizierten Studien uneinheitlich definiert und operationalisiert. Im Rahmen der vorliegenden Arbeit wurde Kriminalität als soziologisches Konstrukt definiert, das maßgeblich von der Gesetzgebung des Landes und weiteren Faktoren abhängt, die außerhalb einer Person liegen (Eysenck, 1977). Demgegenüber wurde antisoziales Verhalten psychologisch definiert, als Verhalten, das anderen Personen schadet aber dem Akteur selbst von Vorteil ist. Da für die Erfassung von antisozialem Verhalten und Kriminalität bis dato noch kein Messinstrument vorliegt, wurde die Checkliste für Antisoziale Verhaltensweisen und Kriminalität (CAV/K, Etzler & Rohrmann, 2017a) entwickelt, die beide Variablen getrennt voneinander aber dennoch simultan erfasst.
Nach Bereitstellung der Definitionen und Messinstrumente wurde untersucht, wie Kriminalität durch psychopathische Eigenschaften vorhergesagt werden kann (Etzler, Rettenberger & Rohrmann, eingereicht). Im Rahmen der adaptiven Psychopathie wurde angenommen, dass Moderatorvariablen den Zusammenhang zwischen Psychopathie und Kriminalität beeinflussen, wobei verbale Intelligenz hierbei eine zentrale Rolle spielt (Wall, Sellbom & Goodwin, 2013). Antisoziales Verhalten und Kriminalität (als offizielle Verurteilung) wurden getrennt voneinander definiert. Es zeigte sich im Rahmen eines moderierten Mediationsmodells, dass psychopathische Eigenschaften antisoziales Verhalten mit hoher Präzision vorhersagen konnten, insbesondere war die Wahrscheinlichkeit, dafür verurteilt zu werden und damit offiziell kriminell zu sein höher für Personen mit niedriger verbaler Intelligenz als für Personen mit höherer Intelligenz, da für verbale Intelligenz ein protektiver Effekt hinsichtlich Kriminalität gefunden wurde.
Die vorliegende Studie verfolgt einen integrativen Ansatz, indem Eigenschaften untersucht werden, die bei Straftätern und Zivilpersonen gleichermaßen vorliegen. Der FPP kann in der Forschung als ökonomisches Instrument eingesetzt werden sowie als Screeninginstrument in der Praxis, z. B. für die Planung des Vollzugsverlaufs in Haft. Anhand der Ergebnisse des FPP können antisoziale Verhaltensweisen in vielen Kontexten (z. B. Mobbing in Unternehmen, deviantes Verhalten in Haft) vorhergesagt werden und unter Hinzunahme weiterer Moderatoren, wie etwa verbale Intelligenz, kann eine präzisere Vorhersage von Kriminalität anhand psychopathischer Eigenschaften erfolgen.
Background: Chronic autoimmune demyelinating polyneuropathies (CADP) result in impaired sensorimotor function. However, anecdotal clinical observations suggest the development of cognitive deficits during the course of disease.
Methods: We tested 16 patients with CADP (11 patients with chronic inflammatory demyelinating polyneuropathy, 4 patients with multifocal motor neuropathy and 1 patient with multifocal acquired demyelinating sensory and motor neuropathy) and 40 healthy controls (HC) with a neuropsychological test battery. Blood-brain-barrier dysfunction (BBBd) in patients was assessed retrospectively by analysing the cerebral spinal fluid (CSF) status at the time the diagnosis of CAPD was established.
Results: CADP patients failed on average in 1.7 out of 9 neuropsychological tests (SD ± 1.25, min. 0, max. 5). 50% of the CADP patients failed in at least two neuropsychological tests and 44.3% of the patients failed in at least two different cognitive domains. CADP patients exhibiting BBBd at the time of first diagnosis failed in more neuropsychological tests than patients with intact integrity of the BBB (p < 0.05). When compared directly with the HC group, CADP patients performed worse than HC in tests measuring information processing ability and speed as well as phonemic verbal fluency after adjusting for confounding covariates.
Conclusions: Our results suggest that mild to moderate cognitive deficits might be present in patients with CAPD. One possible tentative explanation, albeit strong evidence is still lacking for this pathophysiological mechanism, refers to the effect of autoimmune antibodies entering the CNS via the dysfunctional blood-brain barrier typically seen in some of the CADP patients.
Music listening has become a highly individualized activity with smartphones and music streaming services providing listeners with absolute freedom to listen to any kind of music in any situation. Until now, little has been written about the processes underlying the selection of music in daily life. The present study aimed to disentangle some of the complex processes among the listener, situation, and functions of music listening involved in music selection. Utilizing the experience sampling method, data were collected from 119 participants using a smartphone application. For 10 consecutive days, participants received 14 prompts using stratified-random sampling throughout the day and reported on their music-listening behavior. Statistical learning procedures on multilevel regression models and multilevel structural equation modeling were used to determine the most important predictors and analyze mediation processes between person, situation, functions of listening, and music selection. Results revealed that the features of music selected in daily life were predominantly determined by situational characteristics, whereas consistent individual differences were of minor importance. Functions of music listening were found to act as a mediator between characteristics of the situation and music-selection behavior. We further observed several significant random effects, which indicated that individuals differed in how situational variables affected their music selection behavior. Our findings suggest a need to shift the focus of music-listening research from individual differences to situational influences, including potential person-situation interactions.
Numbers and space are two semantic primitives that interact with each other. Both recruit brain regions along the dorsal pathway, notably parietal cortex. This makes parietal cortex a candidate for the origin of numerical–spatial interaction. The underlying cognitive architecture of the interaction is still under scrutiny. Two classes of explanations can be distinguished. The early interaction approach assumes that numerical and spatial information are integrated into a single representation at a semantic level. A second approach postulates independent semantic representations. Only at the stage of response selection and preparation these two streams interact. In this study we used a numerical landmark task to identify the locus of the interaction between numbers and space. While lying in an MR scanner participants decided on the smaller of two numerical intervals in a visually presented number triplet. The spatial position of the middle number was varied; hence spatial intervals were congruent or incongruent with the numerical intervals. Responses in incongruent trials were slower and less accurate than in congruent trials. By combining across-vertex correlations (micro pattern) with a cluster analysis (macro pattern) we identified large-scale networks that were devoted to number processing, eye movements, and sensory–motor functions. Using support vector classification in different regions of interest along the intraparietal sulcus, the frontal eye fields, and supplementary motor area we were able to distinguish between congruent and incongruent trials in each of the networks. We suggest that the identified networks participate in the integration of numerical and spatial information and that the exclusive assumption of either an early or a late interaction between numerical and spatial information does not do justice to the complex interaction between both dimensions.
Objectives: There is promising evidence that mindfulness-based interventions are effective in reducing the symptoms of posttraumatic stress disorder (PTSD). However, until now, studies have often lacked a full clinical PTSD assessment, and interventions are often administered in addition to other interventions. This study examined the feasibility of mindfulness-based stress reduction (MBSR) as a standalone intervention in patients with PTSD who have experienced mixed traumatic events.
Method: Fourteen patients participated in 8 weeks of MBSR. The patients were assessed prior to treatment, post-treatment and at a 1-month follow-up through self-ratings (e.g., the Davidson Trauma Scale) and the Clinician-Administered PTSD Scale to determine the effects of the intervention. Furthermore, after the intervention, the patients participated in qualitative interviews regarding their experiences with MBSR and their ideas for future improvements.
Results: Nine patients finished the program, and these patients considered the exercises to be applicable and helpful. In the Clinician-Administered PTSD Scale, we found large effects regarding the reduction of PTSD symptoms among completers (Cohen's d = 1.2). In the Davidson Trauma Scale, the effect sizes were somewhat lower (Cohen's d = 0.6) but nevertheless confirmed the efficacy of MBSR in reducing PTSD symptoms. In the qualitative interviews, the patients reported an augmentation of wellbeing and improvement regarding the handling of difficult situations and more distance from the traumatic event.
Conclusion: Despite the large effects, the high dropout rates and the results of the post-treatment interviews suggest that the intervention should be better adapted to the needs of PTSD patients, e.g., by giving more information regarding the exercises and by including shorter exercises to manage acute distress.
Human beings are supposed to possess an approximate number system (ANS) dedicated to extracting and representing approximate numerical magnitude information as well as an object tracking system (OTS) for the rapid and accurate enumeration of small sets. It is assumed that the OTS and the ANS independently contribute to the acquisition of more elaborate numerical concepts. Chinese children have been shown to exhibit more elaborate numerical concepts than their non-Chinese peers, but it is still an open question whether similar cross-national differences exist with regard to the underlying systems, namely the ANS and the OTS. In the present study, we investigated this question by comparing Chinese and German preschool children with regard to their performance in a non-symbolic numerical magnitude comparison task (assessing the ANS) and in an enumeration task (assessing the OTS). In addition, we compared children’s counting skills. To ensure that possible between-group differences could not be explained by differences in more general performance factors, we also assessed children’s reasoning ability and processing speed. Chinese children showed a better counting performance and a more accurate performance in the non-symbolic numerical magnitude comparison task. These differences in performance could not be ascribed to differences in reasoning abilities and processing speed. In contrast, Chinese and German children did not differ significantly in the enumeration of small sets. The superior counting performance of Chinese children was thus found to be reflected in the ANS but not in the OTS.
The training of morphological decomposition in word processing and its effects on literacy skills
(2017)
This study set out to examine the effects of a morpheme-based training on reading and spelling in fifth and sixth graders (N = 47), who present poor literacy skills and speak German as a second language. A computerized training, consisting of a visual lexical decision task (comprising 2,880 items, presented in 12 sessions), was designed to encourage fast morphological analysis in word processing. The children were divided between two groups: the one underwent a morpheme-based training, in which word-stems of inflections and derivations were presented for a limited duration, while their pre- and suffixes remained on screen until response. Another group received a control training consisting of the same task, except that the duration of presentation of a non-morphological unit was restricted. In a Word Disruption Task, participants read words under three conditions: morphological separation (with symbols separating between the words’ morphemes), non-morphological separation (with symbols separating between non-morphological units of words), and no-separation (with symbols presented at the beginning and end of each word). The group receiving the morpheme-based program improved more than the control group in terms of word reading fluency in the morphological condition. The former group also presented similar word reading fluency after training in the morphological condition and in the no-separation condition, thereby suggesting that the morpheme-based training contributed to the integration of morphological decomposition into the process of word recognition. At the same time, both groups similarly improved in other measures of word reading fluency. With regard to spelling, the morpheme-based training group showed a larger improvement than the control group in spelling of trained items, and a unique improvement in spelling of untrained items (untrained word-stems integrated into trained pre- and suffixes). The results further suggest some contribution of the morpheme-based training to performance in a standardized spelling task. The morpheme-based training did not, however, show any unique effect on comprehension. These results suggest that the morpheme-based training is effective in enhancing some basic literacy skill in the population examined, i.e., morphological analysis in word processing and the access to orthographic representations in spelling, with no specific effects on reading fluency and comprehension.
Following up on earlier investigations, the present research aims at validating the construct impostor phenomenon by taking other personality correlates into account and to examine whether the impostor phenomenon is a construct in its own right. In addition, gender effects as well as associations with dispositional working styles and strain are examined. In an online study we surveyed a sample of N = 242 individuals occupying leadership positions in different sectors. Confirmatory factor analyses provide empirical evidence for the discriminant validity of the impostor phenomenon. In accord with earlier studies we show that the impostor phenomenon is accompanied by higher levels of anxiety, dysphoric moods, emotional instability, a generally negative self-evaluation, and perfectionism. The study does not reveal any gender differences concerning the impostor phenomenon. With respect to working styles, persons with an impostor self-concept tend to show perfectionist as well as procrastinating behaviors. Moreover, they report being more stressed and strained by their work. In sum, the findings show that the impostor phenomenon constitutes a dysfunctional personality style. Practical implications are discussed.
Das Strukturgleichungsmodell (SEM) wird in den Sozial- und Verhaltenswissenschaften oft verwendet, um die Beziehung zwischen latenten Variablen zu modellieren. In der Analyse dieser Modelle spielt die Bewertung der Modellgüte eine wesentliche Rolle, wobei geprüft werden soll, ob das untersuchte Modell (Zielmodell) zu den erhobenen Daten passt. Dafür werden verschiedene inferenzstatistische und deskriptive Gütemaße verwendet. In nichtlinearen SEM, in denen nichtlineare Effekte, wie beispielsweise Interaktionseffekte, modelliert werden, gibt es bisher allerdings keine Verfahren, um die Modellgüte ausreichend prüfen zu können. Insbesondere der χexp2-Test ist für verschiedene nichtlineare SEM nicht geeignet (vgl. Klein & Schermelleh-Engel, 2010; Mooijaart & Satorra, 2009).
In dieser Arbeit werden zwei unterschiedliche nichtlineare SEM betrachtet. Das erste dieser Modelle wird für die Analyse von Interaktions- und quadratischen Effekten verwendet (quadratisches SEM, QSEM). Das zweite Modell ist das Heterogene Wachstumskurvenmodell (HGM; Klein & Muthén, 2006). In diesem Modell wird das latente Wachstumskurvenmodell (LGM), mit dem individuelle Wachstumsverläufe modelliert werden können, um eine heterogene Varianzkomponente des Slope-Faktors erweitert. Diese Heterogenität des Slope-Faktors ist abhängig von den Ausgangswerten und Kovariaten.
Ziel dieser Arbeit war es, die Bewertung der Modellgüte für das QSEM und das HGM zu verbessern. Für das QSEM und das HGM wurde jeweils ein globaler Modelltest entwickelt („Quasi-Likelihood-Ratio-Test“; QLRT). Darüber hinaus wurden Differenztests für diese Art der Modelle diskutiert. Außerdem wurde für beide Modelle je ein Gütemaß bereitgestellt, um fehlende Nichtlinearität, wie fehlende nichtlineare Terme bzw. fehlende Heterogenität der Slope-Varianzen, aufdecken zu können (der Homoscedastic Fit Index, HFI, für das QSEM und der hhet-Test für das HGM).
Die Entwicklung der neuen Gütemaße ist im Wesentlichen von der verwendeten Schätzmethode abhängig. Für beide Modelle, das QSEM und das HGM, wurde in dieser Arbeit die Quasi-Maximum-Likelihood-Methode (Quasi-ML-Methode; Wedderburn, 1974) ausgewählt, mit der für beide betrachteten Modelle geeignete Schätzungen erzielt werden können (Klein & Muthén, 2006, 2007). Die Quasi-ML-Methode ist vergleichbar mit der Maximum-Likelihood-Methode, berücksichtigt allerdings Fehlspezifikationen der LogLikelihood-Funktion, wie beispielsweise kleinere Abweichungen von der angenommenen Verteilung. Für das QSEM wurde im Rahmen der Entwicklung der Modelltests eine zur Schätzung von QSEM entwickelte Quasi-ML-Methode (QML-Methode; Klein & Muthén, 2007) vereinfacht zu der „simplified QML“-Methode (sQML-Methode; Büchner & Klein, 2019). Für die sQML-Methode ist es erheblich einfacher als für die QML-Methode einen globalen Modelltest zu entwickeln. In einer Simulationsstudie konnte gezeigt werden, dass die sQML-Methode ähnlich gute Schätzeigenschaften wie die QML-Methode aufweist.
Die Idee der neuen globalen Modelltests für das QSEM und das HGM besteht darin, statt des für das lineare SEM verwendeten χexp2-Tests, der ein Likelihood-Quotienten-Test („Likelihood Ratio Test“, LRT) ist, einen Quasi-LRT (QLRT) zu verwenden, der auf der Quasi-ML-Methode basiert (Büchner & Klein, 2019; Büchner, Klein & Irmer, 2019). Wie für den χexp2-Test soll das Zielmodell mit einem unbeschränkten Vergleichsmodell verglichen werden. Ist der Unterschied zwischen den Modellen groß, wird darauf geschlossen, dass das Zielmodell nicht gut zu den Daten passt. Die Schwierigkeit bei der Entwicklung solcher QLRT liegt dabei in der Definition eines Vergleichsmodells. Die hier verwendete Idee für solche Vergleichsmodelle besteht darin, wie im χexp2-Test, die Beschränkungen durch das Zielmodell im Vergleichsmodell aufzuheben. Eine weitere Herausforderung ist die Bestimmung der asymptotischen Verteilung der QLRT-Statistiken, die nicht, wie viele LRT-Statistiken, asymptotisch χexp2-verteilt sind. Deshalb wurde die korrekte asymptotische Verteilung dieser Teststatistiken bestimmt, die das Ermitteln von p-Werten ermöglicht.
Globale Modelltests sind zwar geeignet, wichtige Aussagen zur Passung des Modells zu machen, ermöglichen aber keine direkte Aussage über den Vergleich zweier konkurrierender Modelle. Ein solcher Modellvergleich ist aber wichtig, um ein möglichst sparsames Modell zu erhalten. Zum Vergleich ineinander geschachtelter Modelle werden häufig Differenztests verwendet. Diese werden auch in der Arbeit mit dem QSEM und dem HGM empfohlen. Allerdings ist zu beachten, dass die Teststatistiken für mit der Quasi-MLMethode geschätzten Modelle nicht χexp2-verteilt sind. Im Rahmen dieser Arbeit wurde eine korrekte asymptotische Verteilung angegeben. Im Speziellen wurde der Differenztest für den Vergleich zwischen einem HGM und einem LGM vorgestellt, mit dem getestet wird, ob die im HGM modellierten heterogenen Slope-Varianzen notwendig sind.
Ein weiteres Ziel bestand darin, fehlende Nichtlinearität, die nicht in einem Modell berücksichtigt ist, aufzudecken. Dafür wurde ein Test für Regressionsmodelle, der hhet-Test (Klein, Gerhard, Büchner, Diestel & Schermelleh-Engel, 2016), angepasst. Für das SEM wurde dieser Test zu einem Fit-Index, dem HFI (Gerhard, Büchner, Klein & SchermellehEngel, 2017), weiterentwickelt und darin die Verteilung der Residuen der abhängigen Variable bewertet. Der HFI deckt dabei Veränderungen in der Verteilung auf, die durch fehlende nichtlineare Terme verursacht sind. Für das LGM wird der hhet-Test verwendet, um fehlende heterogene Entwicklungsverläufe aufzudecken. Es wird die Verteilung der mit dem LGM standardisierten beobachteten Variablen geprüft.
Für alle vorgeschlagenen Gütemaße wurden Simulationsstudien durchgeführt, um ihre Eignung für die Bewertung des QSEMs bzw. des HGMs zu prüfen. Die α-Fehler-Raten waren meistens nahe an dem erstrebten 5%-Niveau. Für den QLRT für das QSEM bei kleinen Stichproben und für den HFI bei komplexeren Modellen waren sie allerdings erhöht. Darüber hinaus zeigten die Tests insgesamt eine gute Teststärke für das Aufdecken von Fehlspezifikationen. Wie in allen statistischen Tests muss dafür die Stichprobengröße ausreichend groß sein. Die praktische Anwendbarkeit der beiden QLRTs, des hhet-Tests und des Differenztests für das HGM wurde anhand von empirischen Beispielen aufgezeigt.
Much is known about when children acquire an understanding of mental states, but few, if any, experiments identify social contexts in which children tend to use this capacity and dispositions that influence its usage. Social exclusion is a common situation that compels us to reconnect with new parties, which may crucially involve attending to those parties’ mental states. Across two studies, this line of inquiry was extended to typically developing preschoolers (Study 1) and young children with and without anxiety disorder (AD) (Study 2). Children played the virtual game of toss “Cyberball” ostensibly over the Internet with two peers who first played fair (inclusion), but eventually threw very few balls to the child (exclusion). Before and after Cyberball, children in both studies completed stories about peer-scenarios. For Study 1, 36 typically developing 5-year-olds were randomly assigned to regular exclusion (for no apparent reason) or accidental exclusion (due to an alleged computer malfunction). Compared to accidental exclusion, regular exclusion led children to portray story-characters more strongly as intentional agents (intentionality), with use of more mental state language (MSL), and more between-character affiliation in post-Cyberball stories. For Study 2, 20 clinically referred 4 to 8-year-olds with AD and 15 age- and gender-matched non-anxious controls completed stories before and after regular exclusion. While we replicated the post regular-exclusion increase of intentional and MSL portrayals of story-characters among non-anxious controls, anxious children exhibited a decline on both dimensions after regular exclusion. We conclude that exclusion typically induces young children to mentalize, enabling more effective reconnection with others. However, excessive anxiety may impair controlled mentalizing, which may, in turn, hamper effective reconnection with others after exclusion.
Attractiveness ratings for musicians and non-musicians: An evolutionary-psychology perspective
(2019)
From an evolutionary perspective, musical behavior such as playing an instrument can be considered as part of an individual’s courting behavior. Playing a musical instrument or singing might fulfill a function similar to that of a bird’s colored feathers: attracting attention. Therefore, musicians may be rated as more attractive than non-musicians. In an online survey, 137 volunteers (95 female) with ages ranging from 16 to 39 years rated the attractiveness of fictitious persons of the opposite sex described in short verbal profiles. These profiles differed with respect to whether the described person made music or not. Additionally, the musicians’ profiles varied with regard to whether the described person played music or sang in public or in private only. Results show that musicians’ profiles were not generally rated as more attractive than non-musicians’, but attractiveness did vary according to setting: private musicians were rated as most attractive, followed by non-musicians and public musicians. Furthermore, results indicate that participants who played a musical instrument or sang themselves gave higher ratings to profiles of musicians. But for participants who do not make music themselves, higher attractiveness ratings for musicians playing instruments or sing in private settings were found. These results indicate that the impression of sharing a common interest (making music) and furthermore making music in private instrumental settings seems to make people attractive to other people. No additional support for the sexual selection hypotheses for the evolution of music was provided by the current results. The musical status of the rater affected his or her judgements, with musicians rating other people as more attractive if they share the common interest in making music. Not the display of being a musician seems to be critical for attractiveness ratings but the perceived or imagined similarity by the rater created by information on musicality, fostering the theoretical significance of the communication aspect of music.
Stress often has a negative influence on sports performance. Stress-induced decreases in performance can be especially disastrous for risk sports athletes, who often put their life at risk when practicing their sport. Therefore, it is of great importance to identify protective factors in stressful situations in risk sports. On average, risk sports athletes score extremely high on the personality trait sensation seeking. At the same time, theoretical considerations about dispositional mindfulness suggest that mindful athletes can handle stress more effectively. The main goal of this experiment is to examine the influence of sensation seeking and mindfulness on the stress response to a risk sport-specific stressor. To induce stress, 88 male students completed the Heidelberg Risk Sport-Specific Stress Test (HRSST) which utilizes fear of falling as the stressful event during a climbing exercise. Psychological (anxiety) and physiological (cortisol) responses were measured at multiple time points before and after the HRSST to determine the severity of the stress response. In reaction to the stressor, a significant increase in self-reported state anxiety, but no significant increase in cortisol were observed. The mindfulness subscale external observation correlated positively with anxiety in the climbing wall, sensation seeking and the anxiety scales after the jump correlated negatively and sensation seeking predicted anxiety subscales after the jump in hierarchical regression analyses. However, mindfulness did not predict anxiety measures. Neither sensation seeking nor mindfulness correlated significantly with cortisol levels. The results suggest that high sensation seekers perceive a risk sport-specific stressor as less stressful. The missing physiological response might be explained by the Cross-Stressor-Adaptation-Hypothesis and particularities of the sample. Good internal observers might be especially aware of their need of stimulation and new experiences, which in turn might explain the higher experience-seeking scores. Future studies should further examine the role of mindfulness in stressful situations and the interaction of its subscales with sensation seeking. The current experiment offers new possibilities for adjoining research fields at the interface between sports sciences, psychology and medicine: The findings can be transferred to high risk professions such as police officers, firefighters and military forces (e.g., for selection processes or for interventions).
White matter microstructural changes and episodic memory disturbances in late-onset bipolar disorder
(2018)
Background: Bipolar disorder (BD) has been associated with distributed network disruption, but little is known on how different clinical subtypes, particularly those with an earlier and later onset of disease, are related to connectivity changes in white matter (WM) tracts.
Methods: Diffusion tensor imaging (DTI) and volumetric measures were carried out in early-onset bipolar patients [(EOD) (n = 16)], late-onset bipolar disorder [(LOD)(n = 14)] and healthy controls (n = 32). We also computed ROI analysis of gray matter (GM) and white matter (WM) volumes using the regions with significant group differences in the DTI parameters. Cognitive and behavior measurements were analyzed between groups.
Results: Lower fraction of anisotropy (FA) in the right hemisphere comprising anterior thalamic radiation, fornix, posterior cingulate, internal capsule, splenium of corpus callosum was observed in the LOD in comparison with EOD; additionally, lower FA was also found in the LOD in comparison with healthy controls, mostly in the right hemisphere and comprising fibers of the splenium of the corpus callosum, cingulum, superior frontal gyrus and posterior thalamic radiation; LOD also showed worse episodic memory performance than EOD; no statistical significant differences between mood symptoms, WM and GM volumes were found between BD groups.
Conclusion: Even after correcting for age differences, LOD was associated with more extensive WM microstructural changes and worse episodic memory performance than EOD; these findings suggest that changes in the WM fiber integrity may be associated with a later presentation of BD, possibly due to mechanisms other than neuroprogression. However, these findings deserve replication in larger, prospective, studies.
Object recognition is such an everyday task it seems almost mundane. We look at the spaces around us and name things seemingly effortlessly. Yet understanding how the process of object recognition unfolds is a great challenge to vision science. Models derived from abstract stimuli have little predictive power for the way people explore "naturalistic" scenes and the objects in them. Naturalistic here refers to unaltered photographs of real scenes. This thesis therefore focusses on the process of recognition of the objects in such naturalistic scenes. People can, for instance, find objects in scenes much more efficiently than models derived from abstract stimuli would predict. To explain this kind of behavior, we describe scenes not solely in terms of physical characteristics (colors, contrasts, lines, orientations, etc.) but by the meaning of the whole scene (kitchen, street, bathroom, etc.) and of the objects within the scene (oven, fire hydrant, soap, etc.). Object recognition now refers to the process of the visual system assigning meaning to the object.
The relationship between objects in a naturalistic scene is far from random. Objects do not typically float in mid-air and cannot take up the same physical space. Moreover, certain scenes typically contain certain objects. A fire hydrant in the kitchen would seem like an anomaly to the average observer. These "rules" can be described as the "grammar" of the scene. Scene grammar is involved in multiple aspects of scene- and object perception. There is, for instance, evidence that overall scene category influences identification of individual objects. Typically, experiments that directly target object recognition do not involve eye movements and studies that involve eye movements are not directly aimed at object recognition, but at gaze allocation. But eye movements are abundant in everyday life, they happen roughly 4 times per second. Here we therefore present two studies that use eye movements to investigate when object recognition takes place while people move their eyes from object to object in a scene. The third study is aimed at the application of novel methods for analyzing data from combined eye movement and neurophysiology (EEG) measurements.
One way to study object perception is to violate the grammar of a scene by placing an object in a scene it does not typically occur in and measuring how long people look at the so-called semantic inconsistency, compared to an object that one would expect in the given scene. Typically, people look at semantic inconsistencies longer and more often, signaling that it requires extra processing. In Study 1 we make use of this behavior to ask whether object recognition still happens when it is not necessary for the task. We designed a search task that made it unnecessary to register object identities. Still, participants looked at the inconsistent objects longer than consistent objects, signaling they did indeed process object and scene identities. Interestingly, the inconsistent objects were not remembered better than the consistent ones. We conclude that object and scene identities (their semantics) are processed in an obligatory fashion; when people are involved in a task that does not require it. In Study 2, we investigate more closely when the first signs of object semantic processing are visible while people make eye movements.
Although the finding that semantic inconsistencies are looked at longer and more often has been replicated often, many of these replications look at gaze duration over a whole trial. The question when during a trial differences between consistencies occur, has yielded mixed results. Some studies only report effects of semantic consistency that accumulate over whole trials, whereas others report influences already on the duration of the very first fixations on inconsistent objects. In study 2 we argue that prior studies reporting first fixation duration may have suffered from methodological shortcomings, such as low trial- and sample sizes, in addition to the use of non-robust statistics and data descriptions. We show that a subset of fixations may be influenced more than others (as is indicated by more skewed fixation duration distributions). Further analyses show that the relationship between the effect of object semantics on fixation durations and its effect on oft replicated cumulative measures is not straightforward (fixation duration distributions do not predict dwell effects) but the effect on both measures may be related in a different way. Possibly, the processing of object meaning unfolds over multiple fixations, only when one fixation does not suffice. However, it would be very valuable to be able to study how processing continues, after a fixation ends.
Study 3 aims to make such a measure possible by combining EEG recordings with eye tracking measurements. Difficulties in analyzing eye tracking–EEG data exist because neural responses vary with different eye movements characteristics. Moreover, fixations follow one another in short succession, causing neural responses to each fixation to overlap in time. These issues make the well-established approach of averaging single trial EEG data into ERPs problematic. As an alternative, we propose the use of multiple regression, explicitly modelling both temporal overlap and eye movement parameters. In Study 3 we show that such a method successfully estimates the influence of covariates it is meant to control for. Moreover, we discuss and explore what additional covariates may be modeled and in what way, in order to obtain confound-free estimates of EEG differences between conditions. One important finding is that stimulus properties of physically variable stimuli such as complex scenes, can influence EEG signals and deserve close consideration during experimental design or modelling efforts. Overall, the method compares favorably to averaging methods.
From the studies in this thesis, we directly learn that object recognition is a process that happens in an obligatory fashion, when the task does not require it. We also learn that only a subset of first fixations to objects are affected by the processing of object meaning and its fit to its surroundings. Comparison between first fixation and first dwell effects suggest that, in active vision, object semantics processing sometimes unfolds over multiple fixations. And finally, we learn that regression-based methods for combined eye tracking-EEG analysis provide a plausible way forward for investigating how object recognition unfolds in active vision.
In today’s "new world of work," knowledge workers are often given considerable flexibility regarding where and when to work (i.e., time-spatial flexibility) and this has become a popular approach to redesigning work. Whilst the adoption of such practices is mainly considered a top-down approach to work design, we argue that successful utilization of time-spatial flexibility requires proactivity on the part of the employee in the form of time-spatial job crafting. Previous research has demonstrated that time-spatial flexibility can have both positive and negative effects on well-being, performance, and work-life balance; yet remains mute about the underlying reasons for this and how employees can handle the given flexibility. Drawing on research from work design, we posit that in order for employees to stay well and productive in this context, they need to engage in time-spatial job crafting (i.e., a context-specific form of job crafting that entails reflection on time and place), which can be considered a future work skill. We propose a theoretical model of time-spatial job crafting in which we discuss its components, shed light on its antecedents, and explain how time-spatial job crafting is related to positive work outcomes through a time/spatial-demands fit.
Synesthesia is a phenomenon in which additional perceptual experiences are elicited by sensory stimuli or cognitive concepts. Synesthetes possess a unique type of phenomenal experiences not directly triggered by sensory stimulation. Therefore, for better understanding of consciousness it is relevant to identify the mental and physiological processes that subserve synesthetic experience. In the present work we suggest several reasons why synesthesia has merit for research on consciousness. We first review the research on the dynamic and rapidly growing field of the studies of synesthesia. We particularly draw attention to the role of semantics in synesthesia, which is important for establishing synesthetic associations in the brain. We then propose that the interplay between semantics and sensory input in synesthesia can be helpful for the study of the neural correlates of consciousness, especially when making use of ambiguous stimuli for inducing synesthesia. Finally, synesthesia-related alterations of brain networks and functional connectivity can be of merit for the study of consciousness.
Following a brief review of current efforts to identify the neuronal correlates of conscious processing (NCCP) an attempt is made to bridge the gap between the material neuronal processes and the immaterial dimensions of subjective experience. It is argued that this "hard problem" of consciousness research cannot be solved by only considering the neuronal underpinnings of cognition. The proposal is that the hard problem can be treated within a naturalistic framework if one considers not only the biological but also the socio-cultural dimensions of evolution. The argument is based on the following premises: perceptions are the result of a constructivist process that depends on priors. This applies both for perceptions of the outer world and the perception of oneself. Social interactions between agents endowed with the cognitive abilities of humans generated immaterial realities, addressed as social or cultural realities. This novel class of realities assumed the role of priors for the perception of oneself and the embedding world. A natural consequence of these extended perceptions is a dualist classification of observables into material and immaterial phenomena nurturing the concept of ontological substance dualism. It is argued that perceptions shaped by socio-cultural priors lead to the construction of a self-model that has both a material and an immaterial dimension. As priors are implicit and not amenable to conscious recollection the perceived immaterial dimension is experienced as veridical and not derivable from material processes—which is the hallmark of the hard problem. These considerations let the hard problem appear as the result of cognitive constructs that are amenable to naturalistic explanations in an evolutionary framework.
Reading is not only "cold" information processing, but involves affective and aesthetic processes that go far beyond what current models of word recognition, sentence processing, or text comprehension can explain. To investigate such "hot" reading processes, standardized instruments that quantify both psycholinguistic and emotional variables at the sublexical, lexical, inter-, and supralexical levels (e.g., phonological iconicity, word valence, arousal-span, or passage suspense) are necessary. One such instrument, the Berlin Affective Word List (BAWL) has been used in over 50 published studies demonstrating effects of lexical emotional variables on all relevant processing levels (experiential, behavioral, neuronal). In this paper, we first present new data from several BAWL studies. Together, these studies examine various views on affective effects in reading arising from dimensional (e.g., valence) and discrete emotion features (e.g., happiness), or embodied cognition features like smelling. Second, we extend our investigation of the complex issue of affective word processing to words characterized by a mixture of affects. These words entail positive and negative valence, and/or features making them beautiful or ugly. Finally, we discuss tentative neurocognitive models of affective word processing in the light of the present results, raising new issues for future studies.
Over the last decade, the prospect of improving or maintaining cognitive functioning has provoked a steadily increasing number of cognitive training studies. Central target populations are individuals at risk for a disadvantageous development, such as older adults exhibiting cognitive decline or children with learning impairments. They rely on cognitive resources to meet the challenges of an independent life in old age or requirements at school.
To support daily cognitive functioning, training outcomes need to generalize to other cognitive abilities. Such transfer effects are, however, highly discussed. For example, recent meta-analyses on working memory training differed in the conclusion on the presence (Au et al., 2015; Karbach and Verhaeghen, 2014) or absence of transfer effects (Melby-Lervåg and Hulme, 2013). Usually training-specific design factors such as type, intensity, duration, and feedback routines are discussed as reasons for such inconsistent findings. However, even individuals participating in exactly the same training regime highly differ in their training outcomes. We argue that it is time to study the individual development during trainings to understand these differential outcomes. It is time to have a closer look at the intraindividual training data.
Previous studies used a text-fading procedure as a training tool with the goal to increase silent reading fluency (i.e., proficient reading rate and comprehension). In recently published studies, this procedure resulted in lasting reading enhancements for adult and adolescent research samples. However, studies working with children reported mixed results. While reading rate improvements were observable for Dutch reading children in a text-fading training study, reading fluency improvements in standardized reading tests post-training attributable to the fading manipulation were not detectable. These results raise the question of whether text-fading training is not effective for children or whether research design issues have concealed possible transfer effects. Hence, the present study sought to investigate possible transfer effects resulting from a text-fading based reading training program, using a modified research design. Over a period of 3 weeks, two groups of German third-graders read sentences either with an adaptive text-fading procedure or at their self-paced reading rate. A standardized test measuring reading fluency at the word, sentence, and text level was conducted pre- and post-training. Text level reading fluency improved for both groups equally. Post-training gains at the word level were found for the text-fading group, however, no significant interaction between groups was revealed for word reading fluency. Sentence level reading fluency gains were found for the text-fading group, which significantly differed from the group of children reading at their self-paced reading routine. These findings provide evidence for the efficacy of text-fading as a training method for sentence reading fluency improvement also for children.
Cross education is the process whereby training of one limb gives rise to increases in the subsequent performance of its opposite counterpart. The execution of many unilateral tasks is associated with increased excitability of corticospinal projections from primary motor cortex (M1) to the opposite limb. It has been proposed that these effects are causally related. Our aim was to establish whether changes in corticospinal excitability (CSE) arising from prior training of the opposite limb determine levels of interlimb transfer. We used three vision conditions shown previously to modulate the excitability of corticospinal projections to the inactive (right) limb during wrist flexion movements performed by the training (left) limb. These were: (1) mirrored visual feedback of the training limb; (2) no visual feedback of either limb; and (3) visual feedback of the inactive limb. Training comprised 300 discrete, ballistic wrist flexion movements executed as rapidly as possible. Performance of the right limb on the same task was assessed prior to, at the mid point of, and following left limb training. There was no evidence that variations in the excitability of corticospinal projections (assessed by transcranial magnetic stimulation (TMS)) to the inactive limb were associated with, or predictive of, the extent of interlimb transfer that was expressed. There were however associations between alterations in muscle activation dynamics observed for the untrained limb, and the degree of positive transfer that arose from training of the opposite limb. The results suggest that the acute adaptations that mediate the bilateral performance gains realized through unilateral practice of this ballistic wrist flexion task are mediated by neural elements other than those within M1 that are recruited at rest by single-pulse TMS.
A hypothesis regarding the development of imitation learning is presented that is rooted in intrinsic motivations. It is derived from a recently proposed form of intrinsically motivated learning (IML) for efficient coding in active perception, wherein an agent learns to perform actions with its sense organs to facilitate efficient encoding of the sensory data. To this end, actions of the sense organs that improve the encoding of the sensory data trigger an internally generated reinforcement signal. Here it is argued that the same IML mechanism might also support the development of imitation when general actions beyond those of the sense organs are considered: The learner first observes a tutor performing a behavior and learns a model of the the behavior's sensory consequences. The learner then acts itself and receives an internally generated reinforcement signal reflecting how well the sensory consequences of its own behavior are encoded by the sensory model. Actions that are more similar to those of the tutor will lead to sensory signals that are easier to encode and produce a higher reinforcement signal. Through this, the learner's behavior is progressively tuned to make the sensory consequences of its actions match the learned sensory model. I discuss this mechanism in the context of human language acquisition and bird song learning where similar ideas have been proposed. The suggested mechanism also offers an account for the development of mirror neurons and makes a number of predictions. Overall, it establishes a connection between principles of efficient coding, intrinsic motivations and imitation.
Families are central to the social and emotional development of youth, and most families engage in musical activities together, such as listening to music or talking about their favorite songs. However, empirical evidence of the positive effects of musical family rituals on social cohesion and emotional well-being is scarce. Furthermore, the role of culture in the shaping of musical family rituals and their psychological benefits has been neglected entirely. This paper investigates musical rituals in families and in peer groups (as an important secondary socialization context) in two traditional/collectivistic and two secular/individualistic cultures, and across two developmental stages (adolescence vs. young adulthood). Based on cross-sectional data from 760 young people in Kenya, the Philippines, New Zealand, and Germany, our study revealed that across cultures music listening in families and in peer groups contributes to family and peer cohesion, respectively. Furthermore, the direct contribution of music in peer groups on well-being appears across cultural contexts, whereas musical family rituals affect emotional well-being in more traditional/collectivistic contexts. Developmental analyses show that musical family rituals are consistently and strongly related to family cohesion across developmental stages, whereas musical rituals in peer groups appear more dependent on the developmental stage (in interaction with culture). Contributing to developmental as well as cross-cultural psychology, this research elucidated musical rituals and their positive effects on the emotional and social development of young people across cultures. The implications for future research and family interventions are discussed.
Recent research has revealed that learning behavior is associated with academic achievement at the college level, but the impact of specific learning strategies on academic success as well as gender differences therein are still not clear. Therefore, the aim of this study was to investigate gender differences in the incremental contribution of learning strategies over general cognitive ability in the prediction of academic achievement. The relationship between these variables was examined by correlation analyses. A set of t-tests was used to test for gender differences in learning strategies, whereas structural equation modeling as well as multi-group analyses were applied to investigate the incremental contribution of learning strategies for male and female students’ academic performance. The sample consisted of 461 students (mean age = 21.2 years, SD = 3.2). Correlation analyses revealed that general cognitive ability as well as the learning strategies effort, attention, and learning environment were positively correlated with academic achievement. Gender differences were found in the reported application of many learning strategies. Importantly, the prediction of achievement in structural equation modeling revealed that only effort explained incremental variance (10%) over general cognitive ability. Results of multi-group analyses showed no gender differences in this prediction model. This finding provides further knowledge regarding gender differences in learning research and the specific role of learning strategies for academic achievement. The incremental assessment of learning strategy use as well as gender-differences in their predictive value contributes to the understanding and improvement of successful academic development.
To prepare for an impending event of unknown temporal distribution, humans internally increase the perceived probability of event onset as time elapses. This effect is termed the hazard rate of events. We tested how the neural encoding of hazard rate changes by providing human participants with prior information on temporal event probability. We recorded behavioral and electroencephalographic (EEG) data while participants listened to continuously repeating five-tone sequences, composed of four standard tones followed by a non-target deviant tone, delivered at slow (1.6 Hz) or fast (4 Hz) rates. The task was to detect a rare target tone, which equiprobably appeared at either position two, three or four of the repeating sequence. In this design, potential target position acts as a proxy for elapsed time. For participants uninformed about the target’s distribution, elapsed time to uncertain target onset increased response speed, displaying a significant hazard rate effect at both slow and fast stimulus rates. However, only in fast sequences did prior information about the target’s temporal distribution interact with elapsed time, suppressing the hazard rate. Importantly, in the fast, uninformed condition pre-stimulus power synchronization in the beta band (Beta 1, 15–19 Hz) predicted the hazard rate of response times. Prior information suppressed pre-stimulus power synchronization in the same band, while still significantly predicting response times. We conclude that Beta 1 power does not simply encode the hazard rate, but—more generally—internal estimates of temporal event probability based upon contextual information.
Background: Patient Reported Outcomes (PRO) are gaining more and more importance in the context of clinical trials. The assessment of PRO is frequently performed by questionnaires where the multiple items of a questionnaire are usually pooled within summarizing scores. These scores are used as variables to measure subjective aspects of treatments and diseases. In clinical research, the calculation of these scores is mostly kept very simple, e.g. by a simple summation of item values. In the medical literature, there is hardly any guidance for performing a refinements of questionnaires and for deducing adequate scores. In contrast, in psychometric literature, there are plenty of more sophisticated methods, which overcome typical assumptions made in traditional (sum) scores, however to the prize of more complicated algorithms, which might be difficult to communicate. When faced with the practical task to refine an existing questionnaire, there exist a clear gap of guidance for applied medical researchers. By this article we try to fill this important gap between psychometric theory and medical application by illustrating our methodological choices on the example of a clinical PRO questionnaire.
Methods: Based on our experiences with the refinement of the BCTOS, a PRO questionnaire to assess aesthetic and function after breast conserving therapy in breast cancer patients, we present the following general steps that we performed by refining the BCTOS questionnaire and its scores: 1. Refinement of the length of the questionnaire and the (item-factor) structure. 2. Selection of the factor score estimation method. 3. Validation of the refined questionnaire and scores with respect to validity, reliability and structure based on a validation cohort.
Results: Our step-step-step procedure helped us to shorten the current form of the BCTOS and to redefine the factor structure. By this, the compliance of patients can be increased and the interpretation of the results becomes more coherent.
Conclusions: We present a step-by-step procedure to refine an existing medical questionnaire along with its scores illustrated and discussed by the refinement of the BCTOS.
Trial registration: Due to the character of the study (no intervention study), no registration was performed.
The lateralization of neuronal processing underpinning hearing, speech, language, and music is widely studied, vigorously debated, and still not understood in a satisfactory manner. One set of hypotheses focuses on the temporal structure of perceptual experience and links auditory cortex asymmetries to underlying differences in neural populations with differential temporal sensitivity (e.g., ideas advanced by Zatorre et al. (2002) and Poeppel (2003). The Asymmetric Sampling in Time theory (AST) (Poeppel, 2003), builds on cytoarchitectonic differences between auditory cortices and predicts that modulation frequencies within the range of, roughly, the syllable rate, are more accurately tracked by the right hemisphere. To date, this conjecture is reasonably well supported, since – while there is some heterogeneity in the reported findings – the predicted asymmetrical entrainment has been observed in various experimental protocols. Here, we show that under specific processing demands, the rightward dominance disappears. We propose an enriched and modified version of the asymmetric sampling hypothesis in the context of speech. Recent work (Rimmele et al., 2018b) proposes two different mechanisms to underlie the auditory tracking of the speech envelope: one derived from the intrinsic oscillatory properties of auditory regions; the other induced by top-down signals coming from other non-auditory regions of the brain. We propose that under non-speech listening conditions, the intrinsic auditory mechanism dominates and thus, in line with AST, entrainment is rightward lateralized, as is widely observed. However, (i) depending on individual brain structural/functional differences, and/or (ii) in the context of specific speech listening conditions, the relative weight of the top-down mechanism can increase. In this scenario, the typically observed auditory sampling asymmetry (and its rightward dominance) diminishes or vanishes.
Conventional treatments for mood disorders primarily focus on reducing negative affect, but little on enhancing positive affect. Loving-kindness meditation (LKM) is a traditional meditation practice directly oriented toward enhancing unconditional and positive emotional states of kindness towards oneself and others. We report here two independent and uncontrolled studies carried out at different centers, one in Boston, USA (n = 10), and one in Frankfurt, Germany (n = 8), to examine the potential therapeutic utility of a brief LKM group intervention for symptoms of dysthymia and depression. Results at both centers suggest that LKM was associated with large-sized effects on self-reported symptoms of depression (d = 3.33 and 1.90), negative affect (d = 1.98 and 0.92), and positive affect (d = 1.63 and 0.94). Large effects were also found for clinician-reported changes in depression, rumination and specific positive emotions, and moderate effects for changes in adaptive emotion regulation strategies. The qualitative data analyses provide additional support for the potential clinical utility of the intervention. This proof-of-concept evaluation of LKM as a clinical strategy warrants further investigation.
Die Psychologie unterscheidet interpersonelle Konflikte – also Konflikte zwischen verschiedenen Personen – von intrapsychischen Konflikten – also Konflikten, die sich innerhalb einer Person abspielen. Psychotherapeutisch behandelt werden können Konflikte, wenn alle Konfliktparteien anwesend sind und angesprochen werden können. Insofern kann die Psychoanalyse einzelner Personen vor allem bei intrapsychischen Konflikten helfen, die nach unserem Verständnis psychischen Problemen und Störungen zugrunde liegen. Interpersonelle Konflikte können von Psychotherapeuten in Paar- oder Familientherapien angegangen werden.
