Imitation paradigms are used in various domains of developmental psychological research to assess various cognitive processes such as memory (deferred imitation), action perception and action understanding (mainly direct imitation), as well as categorization and learning about objects (deferred imitation with a change in target objects and generalized imitation). Although these processes are most likely not independent from each other, their relations are still largely unclear. On the one hand, deferred imitation studies have shown that infants' performance improves with increasing age, resulting in the reproduction of more target actions after longer delay intervals. On the other hand, imitation studies focusing on infants' action understanding have found that infants do not necessarily imitate the model's exact actions – actions or action steps that seem to be irrational or irrelevant are omitted by infants under certain circumstances (selective imitation). Additionally, findings of imitation studies that require a transfer of the target actions to novel objects have demonstrated that infants do not only learn about actions, but also about objects, when they engage in imitation.
The present dissertation aims at integrating different perspectives of imitation research by testing 12- and 18-month-old infants in deferred imitation tests consisting of functional vs. arbitrary target actions, and by combining deferred imitation with eye tracking in half of the experiments. A deferred imitation paradigm was chosen to assess memory performance. Systematic variation of target action characteristics enabled the assessment of infants' imitation pattern, i.e., if they would imitate one kind of target actions more frequently than the other. Functionality was chosen as the action characteristic in focus because function is an object's most important property, thus this variation might shed some light on infants' learning about objects in the context of an imitation test. The main goal of the eye tracking experiments was to tackle the relations between infants' visual attention to, and deferred imitation of, different kinds of target actions.
The behavioral experiments revealed that both 12- and 18-month-olds imitated significantly more functional than arbitrary target actions after a delay of 30 minutes. In addition, while 12-month-olds showed a memory effect only for functional actions, 18-month-olds showed a memory effect for both kinds of actions. Thus, 12-month-olds imitated strictly selectively, and 18-month-olds imitated more exactly. This shows that the well established memory effect is modulated by target action functionality, which affects 12- and 18-month-olds' imitation differently. Furthermore, when retested after a two weeks delay, 18-month-olds' performance rates of functional and arbitrary target actions decreased parallel. This suggests that selective imitation is not affected by the duration of the retention interval, and that selection of target actions takes place at an earlier stage of action perception and memory processes.
In the eye tracking experiments, both 12- and 18-month-olds' imitation patterns replicated the findings of the behavioral experiments, showing consistently higher imitation rates of functional than arbitrary target actions. Contrary to this, infants' fixation times to the target actions were not affected by target action functionality. This contrast was supported by statistical analyses that found no clear correspondence between visual attention to and deferred imitation of target actions. This suggests that selective imitation cannot be explained by selective visual attention. Nevertheless, finer-grained analyses of gaze and imitation data in the 18 months old group suggested that infants' increased attention to the social-communicative context of the imitation task was related to more exact imitation, i.e. imitation of not only functional, but also arbitrary target actions.
The findings are discussed against the background of imitation theories, with regard to the relations between different cognitive processes underlying infants' imitation, such as memory, action perception and learning about objects.
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.
Editorial: Positive organizational interventions: contemporary theories, approaches and applications
(2020)
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.
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 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.
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.
Academic self-efficacy (ASE) refers to a student’s global belief in his/her ability to master the various academic challenges at university and is an essential antecedent of wellbeing and performance. The five-item General Academic Self-Efficacy Scale (GASE) showed promise as a short and concise measure for overall ASE. However, of its validity and reliability outside of Scandinavia is limited. Therefore, this paper aimed to investigate the psychometric properties, longitudinal invariance, and criterion validity of the GASE within a sample of university students (Time 1: n = 1056 & Time 2: n = 592) in the USA and Western Europe. The results showed that a unidimensional factorial model of overall ASE fitted the data well was reliable and invariant across time. Further, criterion validity was established by finding a positive relationship with task performance at different time stamps. Therefore, the GASE can be used as a valid and reliable measure for general ASE.
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 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.
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.
Social identification has been shown to be a protective resource for mental health. In this study, the relationships between social identification and emotional, as well as cognitive symptoms of test anxiety are investigated. Participants were university students diagnosed with test anxiety (N = 108). They completed questionnaires regarding a range of psychopathologic stress symptoms, and their social identification with fellow students and with their study program. Results reveal negative relations between social identification and almost all investigated emotional and cognitive symptoms of test anxiety. Based on this study, interventions could be developed that strengthen the social identity of university students.
In the COVID-19 pandemic, human solidarity plays a crucial role in meeting this maybe greatest modern societal challenge. Public health communication targets enhancing collective compliance with protective health and safety regulations. Here, we asked whether authoritarian/controlling message framing as compared to a neutral message framing may be more effective than moralizing/prosocial message framing and whether recipients’ self-rated trait autonomy might lessen these effects. In a German sample (n = 708), we measured approval of seven regulations (e.g., reducing contact, wearing a mask) before and after presenting one of three Twitter messages (authoritarian, moralizing, neutral/control) presented by either a high-authority sender (state secretary) or a low-authority sender (social worker). We found that overall, the messages successfully increased participants’ endorsement of the regulations, but only weakly so because of ceiling effects. Highly autonomous participants showed more consistent responses across the two measurements, i.e., lower response shifting, in line with the concept of reactive autonomy. Specifically, when the sender was a social worker, response shifting correlated negatively with trait autonomy. We suggest that a trusted sender encourages more variable responses to imposed societal regulations in individuals low in autonomy, and we discuss several aspects that may improve health communication.
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.
Objective: To determine whether the performance of multiple sclerosis (MS) patients in the sound-induced flash illusion (SiFi), a multisensory perceptual illusion, would reflect their cognitive impairment.
Methods: We performed the SiFi task as well as an extensive neuropsychological testing in 95 subjects [39 patients with relapse-remitting MS (RRMS), 16 subjects with progressive multiple sclerosis (PMS) and 40 healthy control subjects (HC)].
Results: MS patients reported more frequently the multisensory SiFi than HC. In contrast, there were no group differences in the control conditions. Essentially, patients with progressive type of MS continued to perceive the illusion at stimulus onset asynchronies (SOA) that were more than three times longer than the SOA at which the illusion was already disrupted for healthy controls. Furthermore, MS patients' degree of cognitive impairment measured with a broad neuropsychological battery encompassing tests for memory, attention, executive functions, and fluency was predicted by their performance in the SiFi task for the longest SOA of 500 ms.
Conclusions: These findings support the notion that MS patients exhibit an altered multisensory perception in the SiFi task and that their susceptibility to the perceptual illusion is negatively correlated with their neuropsychological test performance. Since MS lesions affect white matter tracts and cortical regions which seem to be involved in the transfer and processing of both crossmodal and cognitive information, this might be one possible explanation for our findings. SiFi might be considered as a brief, non-expensive, language- and education-independent screening test for cognitive deficits in MS patients.
Developmental differences in the structure of executive function in middle childhood and adolescence
(2013)
Although it has been argued that the structure of executive function (EF) may change developmentally, there is little empirical research to examine this view in middle childhood and adolescence. The main objective of this study was to examine developmental changes in the component structure of EF in a large sample (N = 457) of 7–15 year olds. Participants completed batteries of tasks that measured three components of EF: updating working memory (UWM), inhibition, and shifting. Confirmatory factor analysis (CFA) was used to test five alternative models in 7–9 year olds, 10–12 year olds, and 13–15 year olds. The results of CFA showed that a single-factor EF model best explained EF performance in 7–9-year-old and 10–12-year-old groups, namely unitary EF, though this single factor explained different amounts of variance at these two ages. In contrast, a three-factor model that included UWM, inhibition, and shifting best accounted for the data from 13–15 year olds, namely diverse EF. In sum, during middle childhood, putative measures of UWM, inhibition, and shifting may rely on similar underlying cognitive processes. Importantly, our findings suggest that developmental dissociations in these three EF components do not emerge until children transition into adolescence. These findings provided empirical evidence for the development of EF structure which progressed from unity to diversity during middle childhood and adolescence.
Die vorliegende Arbeit beschäftigt sich mit den Arbeitsgedächtnisleistungen zweier sprachlicher Sondergruppen und der Möglichkeit über die Leistung des Arbeitsgedächtnisses validere Prognosen des weiteren sprachlichen bzw. schriftsprachlichen Entwicklungsverlaufs zu erreichen, als dies über eine ausschließliche Erhebung der Sprachleistung möglich ist. Die Basis dieser Untersuchungen bilden zwei Längsschnittstudien. Die Daten der sprachlichen Sondergruppe der Late Talker (kognitive Aspekte) wurden in Heidelberg an der Universität und dem Frühinterventionszentrum (FRIZ) zwischen dem zweiten und dem neunten Lebensjahr der Kinder (N=93 mit n1=59 Late Talkers und n2=34 Kontrollkindern) in bestimmten Abständen erhoben. Neben den sprachlichen und kognitiven Leistungstests wurde zum letzten Messzeitpunkt zusätzlich die Arbeitsgedächtnisleistung erfasst. Dabei sollte untersucht werden, ob die Leistungen im Arbeitsgedächtnis valide unterscheiden können zwischen Kindern mit persistierenden Sprachentwicklungsproblemen und Kindern, die das Defizit im weiteren Entwicklungsverlauf aufholen (Late Bloomer). Die Ergebnisse zeigen, dass mithilfe der Leistungen in der Phonologischen Schleife eine sehr gute Trennung der Late Bloomer von den Kindern, die weiter eine Sprachproblematik aufweisen, vorgenommen werden kann. Ein Hinzuziehen der zentral-exekutiven Leistungen bringt hingegen keine Verbesserung in der Vorhersagegenauigkeit.
Der zweiten Untersuchung liegen zum einen die Daten der Normierung der Arbeitsgedächtnistestbatterie für Kinder von fünf bis zwölf Jahren (AGTB 5-12 {Hasselhorn et al., 2012}) zugrunde (N=1.669 davon 243 Kinder mit Migrationshintergrund), anhand derer überprüft wurde, ob Kinder mit Migrationshintergrund in irgendeiner Weise durch die Nutzung der Testbatterie benachteiligt werden, sei es 1. Durch die ungeprüfte Übernahme des Arbeitsgedächtnismodells (nach dem Vorbild von Baddeley (1986)), dass für Muttersprachler bereits bestätigt werden konnte, 2. Durch Benachteiligungen in bestimmten Untertests und 3. Durch die Testbatterie im Allgemeinen, die Art der Testung und die Wahl bestimmter Items. Zur Überprüfung, inwieweit Prädiktoren, die bei Muttersprachlern valide Prognosen der späteren schriftsprachlichen Leistungen erlauben, auch bei Kindern mit Migrationshintergrund genutzt werden können, wird ein weiterer längsschnittlicher Datensatz herangezogen. Von den 127 Kindern der Längsschnittstudie des Projekts ANNA „Gedächtnis und Schulfähigkeit“ (Individual Development and Adaptive Education of Children at Risk am Deutschen Institut für internationale pädagogische Forschung - DIPF) weisen 60 Kinder einen Migrationshintergrund auf. Auf Basis beider Datensätze konnte nachgewiesen werden, dass das Modell des Arbeitsgedächtnisses auch bei Kindern mit Migrationshintergrund Anwendung findet und die Benachteiligungen bei der Testung besonders gering ausfallen, je früher die Kinder untersucht werden. Es zeigt sich aber auch, dass die AGTB 5-12 an manchen Stellen überarbeitet werden sollte, um mögliche Benachteiligungen noch weiter zu verringern. Außerdem konnte gezeigt werden, dass sich auch bei Kindern mit Migrationshintergrund valide Prognosen späterer schriftsprachlicher Leistungen anhand ihrer Arbeitsgedächtnisleistungen treffen lassen und hier hauptsächlich auf Basis der phonologischen Gesamtleistungen (alle Untertests).
