Visual search in natural scenes is a complex task relying on peripheral vision to detect potential targets and central vision to verify them. The segregation of the visual fields has been particularly established by on-screen experiments. We conducted a gaze-contingent experiment in virtual reality in order to test how the perceived roles of central and peripheral visions translated to more natural settings. The use of everyday scenes in virtual reality allowed us to study visual attention by implementing a fairly ecological protocol that cannot be implemented in the real world. Central or peripheral vision was masked during visual search, with target objects selected according to scene semantic rules. Analyzing the resulting search behavior, we found that target objects that were not spatially constrained to a probable location within the scene impacted search measures negatively. Our results diverge from on-screen studies in that search performances were only slightly affected by central vision loss. In particular, a central mask did not impact verification times when the target was grammatically constrained to an anchor object. Our findings demonstrates that the role of central vision (up to 6 degrees of eccentricities) in identifying objects in natural scenes seems to be minor, while the role of peripheral preprocessing of targets in immersive real-world searches may have been underestimated by on-screen experiments.
Drawing on insights found in both philosophy and psychology, this paper offers an analysis of hate and distinguishes between its main types. I argue that hate is a sentiment, i.e., a form to regard the other as evil which on certain occasions can be acutely felt. On the basis of this definition, I develop a typology which, unlike the main typologies in philosophy and psychology, does not explain hate in terms of patterns of other affective states. By examining the developmental history and intentional structure of hate, I obtain two variables: the replaceability/irreplaceability of the target and the determinacy/indeterminacy of the focus of concern. The combination of these variables generates the four-types model of hate, according to which hate comes in the following kinds: normative, ideological, retributive, and malicious.
Self-compassion has been theorized to have three components, each with a positive pole and a negative pole: self-kindness versus self-judgment, common humanity versus isolation, and mindfulness versus over-identification. Neff (Self Identity 2:85–101, 2003a) proposes that they mutually influence each other, however, this proposition has not been tested yet. We conducted a pilot study to see if improvements from training one component spilled over to the other two—and whether these trainings had an impact on well-being. 80 participants completed 8 weeks of self-compassionate writing exercises to enhance either self-kindness, common humanity, or mindfulness. Trait self-compassion was assessed using the six-factor model of the self-compassion scale. To address issues of alpha-error-inflation, the false discovery rate was fixed at 5%, and critical p values were adjusted accordingly. Participants in the mindfulness condition reported increased total self-compassion (p = .009), which was accompanied by increased self-kindness (p = .027) and lower isolation (p = .045). Participants in the common humanity condition reported improved total self-compassion (p = .018), lower over-identification (p = .045), and higher life-satisfaction (p = .049). The training in self-kindness failed to improve self-kindness or any other factor. These findings provide initial evidence that the components of self-compassion mutually enhance each other. They also emphasize the importance of mindfulness within the conceptualization of self-compassion.
While Freud regularly discusses the Oedipus complex in the context of the Sophoclean tragedy, the founding document of the psychoanalytic theory of narcissism lacks any trace of the mythological substrate. Both Narcissus, who contributed no less than his name to the psychic phenomenon of narcissism, and Ovid, in whose Metamorphoses the most elaborate and effective elaboration of the myth of Narcissus is laid down, form a conspicuous blank space in Freud's 'Introduction to Narcissism'. This article will attempt to explain this lack of tradition and, in addition, discuss the figure of Pygmalion as a productive form of narcissism that can supplement Freud's theory.
This systematic review investigated how successful children/adolescents with poor literacy skills learn a foreign language compared with their peers with typical literacy skills. Moreover, we explored whether specific characteristics related to participants, foreign language instruction, and assessment moderated scores on foreign language tests in this population. Overall, 16 studies with a total of 968 participants (poor reader/spellers: n = 404; control participants: n = 564) met eligibility criteria. Only studies focusing on English as a foreign language were available. Available data allowed for meta-analyses on 10 different measures of foreign language attainment. In addition to standard mean differences (SMDs), we computed natural logarithms of the ratio of coefficients of variation (CVRs) to capture individual variability between participant groups. Significant between-study heterogeneity, which could not be explained by moderator analyses, limited the interpretation of results. Although children/adolescents with poor literacy skills on average showed lower scores on foreign language phonological awareness, letter knowledge, and reading comprehension measures, their performance varied significantly more than that of control participants. Thus, it remains unclear to what extent group differences between the foreign language scores of children/adolescents with poor and typical literacy skills are representative of individual poor readers/spellers. Taken together, our results indicate that foreign language skills in children/adolescents with poor literacy skills are highly variable. We discuss the limitations of past research that can guide future steps toward a better understanding of individual differences in foreign language attainment of children/adolescents with poor literacy skills.
Background: Autism spectrum disorder (ASD) is characterized by impaired social communication and interaction, and stereotyped, repetitive behaviour and sensory interests. To date, there is no effective medication that can improve social communication and interaction in ASD, and effect sizes of behaviour-based psychotherapy remain in the low to medium range. Consequently, there is a clear need for new treatment options. ASD is associated with altered activation and connectivity patterns in brain areas which process social information. Transcranial direct current stimulation (tDCS) is a technique that applies a weak electrical current to the brain in order to modulate neural excitability and alter connectivity. Combined with specific cognitive tasks, it allows to facilitate and consolidate the respective training effects. Therefore, application of tDCS in brain areas relevant to social cognition in combination with a specific cognitive training is a promising treatment approach for ASD. Methods: A phase-IIa pilot randomized, double-blind, sham-controlled, parallel-group clinical study is presented, which aims at investigating if 10 days of 20-min multi-channel tDCS stimulation of the bilateral tempo-parietal junction (TPJ) at 2.0 mA in combination with a computer-based cognitive training on perspective taking, intention and emotion understanding, can improve social cognitive abilities in children and adolescents with ASD. The main objectives are to describe the change in parent-rated social responsiveness from baseline (within 1 week before first stimulation) to post-intervention (within 7 days after last stimulation) and to monitor safety and tolerability of the intervention. Secondary objectives include the evaluation of change in parent-rated social responsiveness at follow-up (4 weeks after end of intervention), change in other ASD core symptoms and psychopathology, social cognitive abilities and neural functioning post-intervention and at follow-up in order to explore underlying neural and cognitive mechanisms. Discussion: If shown, positive results regarding change in parent-rated social cognition and favourable safety and tolerability of the intervention will confirm tDCS as a promising treatment for ASD core-symptoms. This may be a first step in establishing a new and cost-efficient intervention for individuals with ASD.
Previous research has demonstrated the efficacy of psychological interventions to foster resilience. However, little is known about whether the cultural context in which resilience interventions are implemented affects their efficacy on mental health. Studies performed in Western (k = 175) and Eastern countries (k = 46) regarding different aspects of interventions (setting, mode of delivery, target population, underlying theoretical approach, duration, control group design) and their efficacy on resilience, anxiety, depressive symptoms, quality of life, perceived stress, and social support were compared. Interventions in Eastern countries were longer in duration and tended to be more often conducted in group settings with a focus on family caregivers. We found evidence for larger effect sizes of resilience interventions in Eastern countries for improving resilience (standardized mean difference [SMD] = 0.48, 95% confidence interval [CI] 0.28 to 0.67; p < 0.0001; 43 studies; 6248 participants; I2 = 97.4%). Intercultural differences should receive more attention in resilience intervention research. Future studies could directly compare interventions in different cultural contexts to explain possible underlying causes for differences in their efficacy on mental health outcomes.
Children often perform worse than adults on tasks that require focused attention. While this is commonly regarded as a sign of incomplete cognitive development, a broader attentional focus could also endow children with the ability to find novel solutions to a given task. To test this idea, we investigated children’s ability to discover and use novel aspects of the environment that allowed them to improve their decision-making strategy. Participants were given a simple choice task in which the possibility of strategy improvement was neither mentioned by instructions nor encouraged by explicit error feedback. Among 47 children (8—10 years of age) who were instructed to perform the choice task across two experiments, 27.5% showed a full strategy change. This closely matched the proportion of adults who had the same insight (28.2% of n = 39). The amount of erroneous choices, working memory capacity and inhibitory control, in contrast, indicated substantial disadvantages of children in task execution and cognitive control. A task difficulty manipulation did not affect the results. The stark contrast between age-differences in different aspects of cognitive performance might offer a unique opportunity for educators in fostering learning in children.
Beneficial acute effects of resistance exercise on cognitive functions may be modified by exercise intensity or by habitual physical activity. Twenty-six participants (9 female and 17 male; 25.5 ± 3.4 years) completed four resistance exercise interventions in a randomized order on separate days (≥48 h washout). The intensities were set at 60%, 75%, and 90% of the one repetition maximum (1RM). Three interventions had matched workloads (equal resistance*nrepetitions). One intervention applied 75% of the 1RM and a 50% reduced workload (resistance*nrepetitions = 50%). Cognitive attention (Trail Making Test A—TMTA), task switching (Trail Making Test B—TMTB), and working memory (Digit Reading Spans Backward) were assessed before and immediately after exercise. Habitual activity was assessed as MET hours per week using the International Physical Activity Questionnaire. TMTB time to completion was significantly shorter after exercise with an intensity of 60% 1RM and 75% 1RM and 100% workload. Friedman test indicated a significant effect of exercise intensity in favor of 60% 1RM. TMTA performance was significantly shorter after exercise with an intensity of 60% 1RM, 90% 1RM, and 75% 1RM (50% workload). Habitual activity with vigorous intensity correlated positively with the baseline TMTB and Digit Span Forward performance but not with pre- to post-intervention changes. Task switching, based on working memory, mental flexibility, and inhibition, was beneficially influenced by acute exercise with moderate intensity whereas attention performance was increased after exercise with moderate and vigorous intensity. The effect of regular activity had no impact on acute exercise effects.
Background: Personal treatment goals (PTG) are important means to tailor psychotherapy to the needs of the patient, leading to increased engagement and greater improvement in relevant outcomes. According to lifespan developmental research, motivational goals in old age differ from goals of younger people, with management of losses rather than growth becoming more prevalent. However, this study is the first to systematically investigate age-specific differences in PTGs. Method: We used routine data from patients with major depression assessed at the beginning of outpatient cognitive behavioural therapy. Initial high-priority PTGs were assessed using the Bern Inventory of Treatment Goals (BIT-C). Older patients (≥60 years, n = 52) were matched to younger patients (<60 years, n = 52) with regard to severity of depression, number of comorbidities, gender and level of education. Results: Using a mixed method approach, high-priority PTGs of both age groups were focused most strongly on reducing depressive symptoms and, subsequently, anxiety. At the same time, older patients focused more strongly on PTGs related to well-being and functioning, while younger patients' emphasis was on personal growth. Furthermore, better coping with the ageing process and physical losses emerged as important PTGs for some older patients. Conclusion: Initial PTG themes are specific to diagnosis, but also seem to differ in regard to age. Thus, it is important to develop age-sensitive measures that allow appropriate and efficient tailoring of psychotherapy to meet older patients' needs and preferences.
Background: Increasingly, informal caregivers in Belgium care in group for an older patient. This study aimed to decrease the caregiver burden and to increase the well-being of caregivers and patients by supporting the needs of informal care groups of older patients (≥70 years).
Method: Through an online self-management tool, the groups were supported to make informed choices concerning the care for the older patient, taking into account the standards, values, concerns and needs of every caregiver and patient. A pre-post study was performed.
Results: Although patients and caregivers considered the self-management tool as useful and supportive, no clear evidence for decreased caregiver burden was found. There was a positive trend in group characteristics such as the distribution of tasks, communication and prevalence of conflicts. Caregivers also stated that they took more time for themselves, had less feelings of guilt and experienced less barriers to ask help.
Conclusion: Tailor-made support of informal care groups starts with facilitating and guiding a process to achieve consent within the group to optimise the care for the patient and also for the caregivers. With a shared vision and supported decisions, caregivers can enter into conversations with the professional caregiver to coordinate adjusted support regarding the care needs.
Background and purpose: The ENIGMA-EEG working group was established to enable large-scale international collaborations among cohorts that investigate the genetics of brain function measured with electroencephalography (EEG). In this perspective, we will discuss why analyzing the genetics of functional brain activity may be crucial for understanding how neurological and psychiatric liability genes affect the brain. Methods: We summarize how we have performed our currently largest genome-wide association study of oscillatory brain activity in EEG recordings by meta-analyzing the results across five participating cohorts, resulting in the first genome-wide significant hits for oscillatory brain function located in/near genes that were previously associated with psychiatric disorders. We describe how we have tackled methodological issues surrounding genetic meta-analysis of EEG features. We discuss the importance of harmonizing EEG signal processing, cleaning, and feature extraction. Finally, we explain our selection of EEG features currently being investigated, including the temporal dynamics of oscillations and the connectivity network based on synchronization of oscillations. Results: We present data that show how to perform systematic quality control and evaluate how choices in reference electrode and montage affect individual differences in EEG parameters. Conclusion: The long list of potential challenges to our large-scale meta-analytic approach requires extensive effort and organization between participating cohorts; however, our perspective shows that these challenges are surmountable. Our perspective argues that elucidating the genetic of EEG oscillatory activity is a worthwhile effort in order to elucidate the pathway from gene to disease liability.
Auditory and visual percepts are integrated even when they are not perfectly temporally aligned with each other, especially when the visual signal precedes the auditory signal. This window of temporal integration for asynchronous audiovisual stimuli is relatively well examined in the case of speech, while other natural action-induced sounds have been widely neglected. Here, we studied the detection of audiovisual asynchrony in three different whole-body actions with natural action-induced sounds–hurdling, tap dancing and drumming. In Study 1, we examined whether audiovisual asynchrony detection, assessed by a simultaneity judgment task, differs as a function of sound production intentionality. Based on previous findings, we expected that auditory and visual signals should be integrated over a wider temporal window for actions creating sounds intentionally (tap dancing), compared to actions creating sounds incidentally (hurdling). While percentages of perceived synchrony differed in the expected way, we identified two further factors, namely high event density and low rhythmicity, to induce higher synchrony ratings as well. Therefore, we systematically varied event density and rhythmicity in Study 2, this time using drumming stimuli to exert full control over these variables, and the same simultaneity judgment tasks. Results suggest that high event density leads to a bias to integrate rather than segregate auditory and visual signals, even at relatively large asynchronies. Rhythmicity had a similar, albeit weaker effect, when event density was low. Our findings demonstrate that shorter asynchronies and visual-first asynchronies lead to higher synchrony ratings of whole-body action, pointing to clear parallels with audiovisual integration in speech perception. Overconfidence in the naturally expected, that is, synchrony of sound and sight, was stronger for intentional (vs. incidental) sound production and for movements with high (vs. low) rhythmicity, presumably because both encourage predictive processes. In contrast, high event density appears to increase synchronicity judgments simply because it makes the detection of audiovisual asynchrony more difficult. More studies using real-life audiovisual stimuli with varying event densities and rhythmicities are needed to fully uncover the general mechanisms of audiovisual integration.
22q11.2 Deletion Syndrome (22q11.2DS) is the most common microdeletion in humans, with a heterogenous clinical presentation including medical, behavioural and psychiatric conditions. Previous neuroimaging studies examining the neuroanatomical underpinnings of 22q11.2DS show alterations in cortical volume (CV), cortical thickness (CT) and surface area (SA). The aim of this study was to identify (1) the spatially distributed networks of differences in CT and SA in 22q11.2DS compared to controls, (2) their unique and spatial overlap, as well as (3) their relative contribution to observed differences in CV. Structural MRI scans were obtained from 62 individuals with 22q11.2DS and 57 age-and-gender-matched controls (aged 6–31). Using FreeSurfer, we examined differences in vertex-wise estimates of CV, CT and SA at each vertex, and compared the frequencies of vertices with a unique or overlapping difference for each morphometric feature. Our findings indicate that CT and SA make both common and unique contributions to volumetric differences in 22q11.2DS, and in some areas, their strong opposite effects mask differences in CV. By identifying the neuroanatomic variability in 22q11.2DS, and the separate contributions of CT and SA, we can start exploring the shared and distinct mechanisms that mediate neuropsychiatric symptoms across disorders, e.g. 22q11.2DS-related ASD and/or psychosis/schizophrenia.
'THIS ISN'T ME!': the role of age-related self- and user images for robot acceptance by elders
(2020)
Although companion-type robots are already commercially available, little interest has been taken in identifying reasons for inter-individual differences in their acceptance. Elders’ age-related perceptions of both their own self (self-image) and of the general older robot user (user image) could play a relevant role in this context. Since little is known to date about elders’ companion-type robot user image, it is one aim of this study to investigate its age-related facets, concentrating on possibly stigmatizing perceptions of elder robot users. The study also addresses the association between elders’ age-related self-image and robot acceptance: Is the association independent of the user image or not? To investigate these research questions, N = 28 adults aged 63 years and older were introduced to the companion-type robot Pleo. Afterwards, several markers of robot acceptance were assessed. Actual and ideal self- and subjective robot user image were assessed by a study-specific semantic differential on the stereotype dimensions of warmth and competence. Results show that participants tended to stigmatize elder robot users. The self-images were not directly related to robot acceptance, but affected it in the context of the user image. A higher fit between self- and user image was associated with higher perceived usefulness, social acceptance, and intention to use the robot. To conclude, elders’ subjective interpretations of new technologies play a relevant role for their acceptance. Together with elders’ individual self-images, they need to be considered in both robot development and implementation. Future research should consider that associations between user characteristics and robot acceptance by elders can be complex and easily overlooked.
Fragestellung: Es existiert eine Vielzahl von Begriffen für Verhaltenssüchte, die Mängel in Operationalisierung, Bezug zum Verhalten, Kompatibilität mit internationalen Klassifikationen sowie nicht stigmatisierender Nutzung aufweisen. Daher werden einheitliche Begriffe für Verhaltenssüchte benötigt. Methode: Im Rahmen einer Leitlinie zur Diagnostik und Behandlung Internetbezogener Störungen wurden Lösungen in Form eines Expertenkonsens entwickelt. Ergebnisse: Als Grundlage wurde die Einteilung von Verhaltenssüchten in der 11. Revision der International Classification of Diseases (ICD-11) genutzt. Es wurden die Begriffe Computerspielstörung (CSS) und Glücksspielstörung (GSS) für die beiden in ICD-11 enthaltenen Verhaltenssüchte gewählt sowie drei weitere spezifizierte Verhaltenssüchte vorgeschlagen: Soziale-Netzwerke-Nutzungsstörung (SNS), Shoppingstörung (ShS) und Pornografie-Nutzungsstörung (PNS). Für CSS, GSS und ShS wird weiterhin zwischen vorwiegend online oder vorwiegend offline unterschieden. Als Oberbegriff wird Störungen aufgrund von Verhaltenssüchten vorgeschlagen. Für Störungen aufgrund von Verhaltenssüchten, die sich vorwiegend auf online ausgeübte Verhaltensweisen beziehen, kann alternativ der Oberbegriff Internetnutzungsstörungen verwendet werden. Schlussfolgerung: Die vorgeschlagenen Termini weisen Verbesserungen im Vergleich zu uneindeutigen oder aus anderen Gründen ungünstigen Begriffen dar. Gleichzeitig konnte eine Kompatibilität mit der ICD-11 ermöglicht werden.
Background: Autism spectrum disorder (“autism”) is a highly heterogeneous neurodevelopmental condition with few effective treatments for core and associated features. To make progress we need to both identify and validate neural markers that help to parse heterogeneity to tailor therapies to specific neurobiological profiles. Atypical hemispheric lateralization is a stable feature across studies in autism, but its potential as a neural stratification marker has not been widely examined. Methods: In order to dissect heterogeneity in lateralization in autism, we used the large EU-AIMS (European Autism Interventions—A Multicentre Study for Developing New Medications) Longitudinal European Autism Project dataset comprising 352 individuals with autism and 233 neurotypical control subjects as well as a replication dataset from ABIDE (Autism Brain Imaging Data Exchange) (513 individuals with autism, 691 neurotypical subjects) using a promising approach that moves beyond mean group comparisons. We derived gray matter voxelwise laterality values for each subject and modeled individual deviations from the normative pattern of brain laterality across age using normative modeling. Results: Individuals with autism had highly individualized patterns of both extreme right- and leftward deviations, particularly in language, motor, and visuospatial regions, associated with symptom severity. Language delay explained most variance in extreme rightward patterns, whereas core autism symptom severity explained most variance in extreme leftward patterns. Follow-up analyses showed that a stepwise pattern emerged, with individuals with autism with language delay showing more pronounced rightward deviations than individuals with autism without language delay. Conclusions: Our analyses corroborate the need for novel (dimensional) approaches to delineate the heterogeneous neuroanatomy in autism and indicate that atypical lateralization may constitute a neurophenotype for clinically meaningful stratification in autism.
Die Stichtagserhebung der Kriminologischen Zentralstelle (KrimZ) fragt jedes Jahr zum Stichtag am 31. März die Gegebenheiten in allen sozialtherapeutischen Einrichtungen deutschlandweit ab. Inzwischen liegen Daten aus 23 Erhebungsjahren vor und geben Aufschluss über die Entwicklungen der Versorgungslage (Anzahl der Einrichtungen bzw. Haftplätze), bezüglich der demografischen Daten der Gefangenen (Alter, Staatsbürgerschaft, Dauer der Haftstrafe, schwerste Straftat, Vorstrafen), über institutionelle Vorgänge (Aufnahmen, Abgänge und Nachbetreuung) sowie hinsichtlich von Daten zum Personal (Anzahl der Personalstellen und Frauenanteil). Die vorliegenden Auswertungen verdeutlichen die Entwicklungstrends in der Sozialtherapie zwischen 1997 und 2019 und legen nahe, dass nach einem starken Ausbau der sozialtherapeutischen Einrichtungen ab 1969 nun mit 71 Einrichtungen eine Sättigungsgrenze erreicht zu sein scheint. Die inhaftierten Personen werden zunehmend älter, sodass 2019 die über 50-Jährigen die größte Altersgruppe stellen. Schon seit 2003 liegt der Anteil derjenigen, die aufgrund eines Sexualdelikts inhaftiert sind, bei ca. 50 %, was gegenüber anderen Deliktgruppen eine deutliche Mehrheit darstellt. Ein Großteil der Gefangenen hat keine Haftlockerungen, wobei hier eine zunehmend restriktivere Praxis zu erkennen ist. Die Personalausstattung hat sich über die letzten 23 Jahre insofern verändert, als dass mehr Fachdienste und tendenziell weniger Stellen im allgemeinen Vollzugsdienst (AVD) eingerichtet wurden.
Understanding effects of emotional valence and stress on children’s memory is important for educational and legal contexts. This study disentangled the effects of emotional content of to-be-remembered information (i.e., items differing in emotional valence and arousal), stress exposure, and associated cortisol secretion on children’s memory. We also examined whether girls’ memory is more affected by stress induction. A total of 143 6- and 7-year-old children were randomly allocated to the Trier Social Stress Test for Children (n = 103) or a control condition (n = 40). At 25 min after stressor onset, children incidentally encoded 75 objects varying in emotional valence (crossed with arousal) together with neutral scene backgrounds. We found that response bias corrected memory was worse for low-arousing negative items than for neutral and positive items, with the latter two categories not being different from each other. Whereas boys’ memory was largely unaffected by stress, girls in the stress condition showed worse memory for negative items, especially the low-arousing ones, than girls in the control condition. Girls, compared with boys, reported higher subjective stress increases following stress exposure and had higher cortisol stress responses. Whereas a higher cortisol stress response was associated with better emotional memory in girls in the stress condition, boys’ memory was not associated with their cortisol secretion. Taken together, our study suggests that 6- and 7-year-old children, more so girls, show memory suppression for negative information. Girls’ memory for negative information, compared with that of boys, is also more strongly modulated by stress experience and the associated cortisol response.
Wörter flüssig und genau lesen zu können ist ein wichtiger Meilenstein beim Lesenlernen, den jedoch nicht alle Kinder erreichen. Schwachen Leser/innen bereitet es oft Schwierig-keiten, den Übergang vom buchstabenweisen Einlesen hin zur visuellen Worterkennung durch orthografische Vergleichsprozesse anhand größerer (sub-)lexikalischer Einheiten zu schaffen. Dabei ermöglicht die Silbe Kindern, die im Deutschen lesen lernen, den Einstieg in orthografische Vergleichsprozesse. Vor diesem Hintergrund untersuchte diese Replikations-studie in einem experimentellen Prä-Post-Design die Wirksamkeit eines silbenbasierten Le-setrainings auf die visuelle Worterkennung und das Leseverständnis von Zweitklässler/innen. Dazu wurden 101 Kinder, deren Worterkennungsleistung in einem standardisierten Lesetest im Vergleich zur Klassennorm unter dem Mittelwert lag, randomisiert der Experimental- oder Wartekontrollgruppe zugewiesen. Die Ergebnisse linearer Modelle nach Abschluss des 24 Sitzungen umfassenden Kleingruppentrainings zeigen signifikante Verbesserungen der orthografischen Vergleichsprozesse in der Experimentalgruppe. Demnach gelang es Kindern, die das Training des wiederholten Lesens und Segmentierens frequenter Silben erhalten hat-ten, Wörter schneller und genauer zu erkennen. Dieser Befund stellt einen weiteren Beleg für die Wirksamkeit des Trainings zur Förderung der Erkennung geschriebener Wörter dar.
Sprach- und Sprechstörungen kommen bei zahlreichen Kindern vor und werden in der ICD-11 analog zur ICD-10 als Entwicklungsstörungen im Kapitel 6 (Psychische, Verhaltens- und Entwicklungsstörungen) klassifiziert. International sind bislang die ICD-10-Kriterien nicht von allen Professionen, die sich mit Sprach- und Sprechstörungen klinisch oder im Rahmen der Forschung beschäftigen, akzeptiert. Sie werden einerseits als zu wenig differenziert hinsichtlich der unterschiedlichen Sprachkomponenten vonseiten der Linguistik, Sprachtherapie oder Logopädie erlebt. Zum anderen wird die unklare Abgrenzung organisch bedingter Sprach- und Sprechprobleme von der Sprachentwicklungsstörung vonseiten der Medizin teilweise kritisch bewertet. In dem vorliegenden Artikel wird deshalb einerseits die Klassifikation von Sprach- und Sprechproblemen und -störungen in der ICD-11 im Vergleich zur ICD-10 vorgenommen. Wesentlich erscheint hier die in der ICD-11 neu eingeführte Differenzierung in „primäre“ und „sekundäre“ Neuroentwicklungsstörungen. Zum anderen erfolgt aber auch eine Auseinandersetzung mit dem DSM-5 sowie anderen Klassifikationsvorschlägen vonseiten der englischsprachigen Sprachtherapie (CATALISE-2) und der deutschsprachigen Pädaudiologie („phonologische Wahrnehmungsstörung“) sowie der Vorschlag einer Ergänzung der aktuellen ICD-11-Klassifikation hinsichtlich konkreter sprachlicher Einschränkungen bei einem Kind mit Sprachentwicklungsstörung, basierend auf einer ausführlichen Diagnostik. Wir hoffen, mit dem Artikel so den Weg für eine berufsübergreifende Klassifikation von Sprach- und Sprechstörungen nach ICD-11 zu bahnen, damit perspektivisch alle Berufsgruppen, die Diagnostik und Therapie der betroffenen Personen anbieten, eine vergleichbare Terminologie verwenden. Diese vergleichbare Terminologie soll sowohl die klinische Versorgung verbessern als auch die unterschiedlichen Forschungsansätze und -richtungen vergleichbarer machen.
Never good enough: the relation between the impostor phenomenon and multidimensional perfectionism
(2020)
The Impostor Phenomenon can be described as the tendency to attribute professional success not to one’s own abilities but to excessive effort or fortunate external circumstances. Individuals strongly experiencing those tendencies fear that one day they will be exposed as “impostors” as soon as their alleged incompetence can no longer be concealed. Typical characteristics of the Impostor Phenomenon outlined by Clance (1985) show a remarkable conceptual similarity to the personality construct of perfectionism. Thus, the present study aimed at investigating how the Impostor Phenomenon is related to various facets of dispositional perfectionism with respect to predominant conceptualizations of perfectionism by Frost et al. (1990), Hewitt and Flett (1991), as well as their combination within the bifactor model of Perfectionistic Strivings and Perfectionistic Concerns (Frost et al. 1993). A total of N = 274 individuals participated in an online survey including the Impostor Phenomenon Scale (CIPS; Clance 1988), the Frost Multidimensional Perfectionism Scale (FMPS; Frost et al. 1990), and the Hewitt und Flett Multidimensional Perfectionism Scale (MPS short form; Hewitt et al. 2008). Hierarchical regression analyses were conducted to determine the differential contributions of perfectionism dimensions and factors in predicting the Impostor Phenomenon. The perfectionism dimensions Doubts about Actions, Concern over Mistakes and Socially prescribed Perfectionism appeared to be efficient predictors of the Impostor Phenomenon. Contrary to Perfectionistic Strivings, Perfectionistic Concerns as a maladaptive perfectionism factor strongly contributed to the prediction of the Impostor Phenomenon. Theoretical and practical implications of the associations between the Impostor Phenomenon and multidimensional perfectionism are discussed.
The major depressive disorder is one of the most common mental illnesses worldwide. Current treatment standards recommend a combined therapy with medication and psychotherapy. As an additive component and to further improvements in treatment, physical activity such as yoga may be integrated into conventional treatment. This study investigates the impact of a 3-month body-oriented yoga in patients with major depressive disorder (MDD). In total, n = 83 patients were included. An intervention group received a vigorous Ashtanga-Yoga three times a week. The waiting-list control group obtained a treatment as usual (TAU). As a primary outcome depression scores (Beck Depression Inventory-II (BDI-II), Montgomery Asberg Depression Rating Scale (MADRS)) were tested at three time points. Secondary outcome was the positive and negative affect [Positive and Negative Affect Scale (PANAS)] and remission rates. To analyze the data, multilevel models and effect sizes were conducted. The results showed an improvement in BDI-II scores for both groups over time [γ = − 3.46, t(165) = − 7.99, p < 0.001] but not between groups [γ = 0.98, t(164) = 1.12, p = 0.263]. An interaction effect (time x group) occurred for MADRS [γ = 2.10, t(164) = 2.10, p < 0.038]. Positive affects improved over time for both groups [γ = 1.65, t(165) = 4.03, p < 0.001]. Negative affects decreased for all over time [γ = − 1.00, t(165) = − 2.51, p = 0.013]. There were no significant group differences in PANAS. Post hoc tests revealed a greater symptom reduction within the first 6 weeks for all measurements. The effect sizes for depression scores showed a positive trend. Remission rates indicated a significant improvement in the yoga group (BDI-II: 46.81%, MADRS: 17.02%) compared to the control group (BDI: 33.33%, MADRS: 8.33%). The findings suggest that there is a trendsetting additive effect of Ashtanga-Yoga after 3 months on psychopathology and mood with a greater improvement at the beginning of the intervention. Further research in this field can help to achieve more differentiated results.
Cross-sectional findings suggest that volumes of specific hippocampal subfields increase in middle childhood and early adolescence. In contrast, a small number of available longitudinal studies reported decreased volumes in most subfields over this age range. Further, it remains unknown whether structural changes in development are associated with corresponding gains in children’s memory. Here we report cross-sectional age differences in children’s hippocampal subfield volumes together with longitudinal developmental trajectories and their relationships with memory performance. In two waves, 109 participants aged 6–10 years (wave 1: MAge=7.25, wave 2: MAge=9.27) underwent high-resolution magnetic resonance imaging to assess hippocampal subfield volumes (imaging data available at both waves for 65 participants) and completed tasks assessing hippocampus dependent memory processes. We found that cross-sectional age-associations and longitudinal developmental trends in hippocampal subfield volumes were discrepant, both by subfields and in direction. Further, volumetric changes were largely unrelated to changes in memory, with the exception that increase in subiculum volume was associated with gains in spatial memory. Longitudinal and cross-sectional patterns of brain-cognition couplings were also discrepant. We discuss potential sources of these discrepancies. This study underscores that children’s structural brain development and its relationship to cognition cannot be inferred from cross-sectional age comparisons.

Resilience has been defined as the maintenance or quick recovery of mental health during and after times of adversity. How to operationalize resilience and to determine the factors and processes that lead to good long-term mental health outcomes in stressor-exposed individuals is a matter of ongoing debate and of critical importance for the advancement of the field. One of the biggest challenges for implementing an outcome-based definition of resilience in longitudinal observational study designs lies in the fact that real-life adversity is usually unpredictable and that its substantial qualitative as well as temporal variability between subjects often precludes defining circumscribed time windows of inter-individually comparable stressor exposure relative to which the maintenance or recovery of mental health can be determined. To address this pertinent issue, we propose to frequently and regularly monitor stressor exposure (E) and mental health problems (P) throughout a study's observation period [Frequent Stressor and Mental Health Monitoring (FRESHMO)-paradigm]. On this basis, a subject's deviation at any single monitoring time point from the study sample's normative E–P relationship (the regression residual) can be used to calculate that subject's current mental health reactivity to stressor exposure (“stressor reactivity,” SR). The SR score takes into account the individual extent of experienced adversity and is comparable between and within subjects. Individual SR time courses across monitoring time points reflect intra-individual temporal variability in SR, where periods of under-reactivity (negative SR score) are associated with accumulation of fewer mental health problems than is normal for the sample. If FRESHMO is accompanied by regular measurement of potential resilience factors, temporal changes in resilience factors can be used to predict SR time courses. An increase in a resilience factor measurement explaining a lagged decrease in SR can then be considered to index a process of adaptation to stressor exposure that promotes a resilient outcome (an allostatic resilience process). This design principle allows resilience research to move beyond merely determining baseline predictors of resilience outcomes, which cannot inform about how individuals successfully adjust and adapt when confronted with adversity. Hence, FRESHMO plus regular resilience factor monitoring incorporates a dynamic-systems perspective into resilience research.
Drawing on insights found in both philosophy and psychology, this paper offers an analysis of hate and distinguishes between its main types. I argue that hate is a sentiment, i.e., a form to regard the other as evil which on certain occasions can be acutely felt. On the basis of this definition, I develop a typology which, unlike the main typologies in philosophy and psychology, does not explain hate in terms of patterns of other affective states. By examining the developmental history and intentional structure of hate, I obtain two variables: the replaceability/irreplaceability of the target and the determinacy/indeterminacy of the focus of concern. The combination of these variables generates the four-types model of hate, according to which hate comes in the following kinds: normative, ideological, retributive, and malicious.
Human observers can quickly and accurately categorize scenes. This remarkable ability is related to the usage of information at different spatial frequencies (SFs) following a coarse-to-fine pattern: Low SFs, conveying coarse layout information, are thought to be used earlier than high SFs, representing more fine-grained information. Alternatives to this pattern have rarely been considered. Here, we probed all possible SF usage strategies randomly with high resolution in both the SF and time dimensions at two categorization levels. We show that correct basic-level categorizations of indoor scenes are linked to the sampling of relatively high SFs, whereas correct outdoor scene categorizations are predicted by an early use of high SFs and a later use of low SFs (fine-to-coarse pattern of SF usage). Superordinate-level categorizations (indoor vs. outdoor scenes) rely on lower SFs early on, followed by a shift to higher SFs and a subsequent shift back to lower SFs in late stages. In summary, our results show no consistent pattern of SF usage across tasks and only partially replicate the diagnostic SFs found in previous studies. We therefore propose that SF sampling strategies of observers differ with varying stimulus and task characteristics, thus favouring the notion of flexible SF usage.
The cell—cell signaling gene CDH13 is associated with a wide spectrum of neuropsychiatric disorders, including attention-deficit/hyperactivity disorder (ADHD), autism, and major depression. CDH13 regulates axonal outgrowth and synapse formation, substantiating its relevance for neurodevelopmental processes. Several studies support the influence of CDH13 on personality traits, behavior, and executive functions. However, evidence for functional effects of common gene variation in the CDH13 gene in humans is sparse. Therefore, we tested for association of a functional intronic CDH13 SNP rs2199430 with ADHD in a sample of 998 adult patients and 884 healthy controls. The Big Five personality traits were assessed by the NEO-PI-R questionnaire. Assuming that altered neural correlates of working memory and cognitive response inhibition show genotype-dependent alterations, task performance and electroencephalographic event-related potentials were measured by n-back and continuous performance (Go/NoGo) tasks. The rs2199430 genotype was not associated with adult ADHD on the categorical diagnosis level. However, rs2199430 was significantly associated with agreeableness, with minor G allele homozygotes scoring lower than A allele carriers. Whereas task performance was not affected by genotype, a significant heterosis effect limited to the ADHD group was identified for the n-back task. Heterozygotes (AG) exhibited significantly higher N200 amplitudes during both the 1-back and 2-back condition in the central electrode position Cz. Consequently, the common genetic variation of CDH13 is associated with personality traits and impacts neural processing during working memory tasks. Thus, CDH13 might contribute to symptomatic core dysfunctions of social and cognitive impairment in ADHD.
Der vorliegende Beitrag untersucht die Bedeutung von individuellen Merkmalen (Fähigkeitsselbstkonzept und Leistungsängstlichkeit) sowie von konstruktiver Unterstützung durch Lehrkräfte für die soziale Integration von Schülerinnen und Schülern in der Sekundarstufe. Bezüglich des Unterrichtsqualitätsmerkmals der konstruktiven Unterstützung wird zwischen zwei Facetten unterschieden, nämlich einer sozio-emotionalen Unterstützung sowie einer fachlich-inhaltlichen Unterstützung durch die Lehrkraft. Dabei wird erstmals die Bedeutung dieser Facetten für die von Schülerinnen und Schülern erlebte soziale Integration untersucht und ebenso geprüft, welche differenziellen Zusammenhänge sich für Lernende mit individuellen Risikofaktoren schulischer Entwicklung zeigen. Es wurden Befragungsdaten aus zwei Erhebungszeitpunkten (mittlerer Abstand: 8 Wochen) von 1.116 Schülerinnen und Schülern in 49 Mathematikklassen der Sekundarstufe mehrebenen-analytisch ausgewertet. Die Ergebnisse zeigen, dass beide Facetten konstruktiver Unterstützung mit dem Erleben sozialer Integration zusammenhingen. Schülerinnen und Schüler mit niedrigem Mathematik-Fähigkeitsselbstkonzept bzw. hoher Leistungsängstlichkeit fühlten sich weniger gut in die Klassengemeinschaft integriert. Die Facetten konstruktiver Unterstützung spielten für diese Zusammenhänge eine besondere Rolle: Der Zusammenhang zwischen Fähigkeitsselbstkonzept und sozialer Integration wurde durch eine fachlich-inhaltliche Unterstützung moderiert, sodass sich Lernende mit niedrigem Fähigkeitsselbstkonzept in Klassen mit hoher fachlich-inhaltlicher Unterstützung vergleichbar gut sozial integriert fühlten wie die anderen Lernenden. Der Zusammenhang von Leistungsängstlichkeit und sozialer Integration wurde durch beide Facetten konstruktiver Unterstützung moderiert, sodass in Klassen mit hoher konstruktiver Unterstützung Lernende mit hoher Leistungsängstlichkeit sich genauso sozial integriert erlebten wie ihre weniger leistungsängstlichen Mitschülerinnen und Mitschüler. Der Beitrag untermauert somit die hohe Bedeutung von Beziehungsqualität im schulischen Kontext und bringt neue Erkenntnisse zu differenziellen Zusammenhängen von Unterricht und schulischen Outcomes in Abhängigkeit von den Lernvoraussetzungen der Schülerinnen und Schüler.
Humans accumulate knowledge throughout their entire lives. In what ways does this accumulation of knowledge influence learning of new information? Are there age-related differences in the way prior knowledge is leveraged for remembering new information? We review studies that have investigated these questions, focusing on those that have used the memory congruency effect, which provides a quantitative measure of memory advantage because of prior knowledge. Regarding the first question, evidence suggests that the accumulation of knowledge is a key factor promoting the development of memory across childhood and counteracting some of the decline in older age. Regarding the second question, evidence suggests that, if available knowledge is controlled for, age-related differences in the memory congruency effect largely disappear. These results point to an age-invariance in the way prior knowledge is leveraged for learning new information. Research on neural mechanisms and implications for application are discussed.
From age 5 to 7, there are remarkable improvements in children’s cognitive abilities (“5–7 shift”). In many countries, including Germany, formal schooling begins in this age range. It is, thus, unclear to what extent exposure to formal schooling contributes to the “5–7 shift.” In this longitudinal study, we investigated if schooling acts as a catalyst of maturation. We tested 5-year-old children who were born close to the official cutoff date for school entry and who were still attending a play-oriented kindergarten. One year later, the children were tested again. Some of the children had experienced their first year of schooling whereas the others had remained in kindergarten. Using 2 functional magnetic resonance imaging tasks that assessed episodic memory formation (i.e., subsequent memory effect), we found that children relied strongly on the medial temporal lobe (MTL) at both time points but not on the prefrontal cortex (PFC). In contrast, older children and adults typically show subsequent memory effects in both MTL and PFC. Both children groups improved in their memory performance, but there were no longitudinal changes nor group differences in neural activation. We conclude that successful memory formation in this age group relies more heavily on the MTL than in older age groups.
Digital distractions can interfere with goal attainment and lead to undesirable habits that are hard to get red rid of. Various digital self-control interventions promise support to alleviate the negative impact of digital distractions. These interventions use different approaches, such as the blocking of apps and websites, goal setting, or visualizations of device usage statistics. While many apps and browser extensions make use of these features, little is known about their effectiveness. This systematic review synthesizes the current research to provide insights into the effectiveness of the different kinds of interventions. From a search of the ‘ACM’, ‘Springer Link’, ‘Web of Science’, ’IEEE Xplore’ and ‘Pubmed’ databases, we identified 28 digital self-control interventions. We categorized these interventions according to their features and their outcomes. The interventions showed varying degrees of effectiveness, and especially interventions that relied purely on increasing the participants' awareness were barely effective. For those interventions that sanctioned the use of distractions, the current literature indicates that the sanctions have to be sufficiently difficult to overcome, as they will otherwise be quickly dismissed. The overall confidence in the results is low, with small sample sizes, short study duration, and unclear study contexts. From these insights, we highlight research gaps and close with suggestions for future research.
Visual working memory (VWM) is reliably predictive of fluid intelligence and academic achievements. The objective of the current study was to investigate individual differences in pre-schoolers’ VWM processing by examining the association between behaviour, brain function and parent-reported measures related to the child's environment. We used a portable functional near-infrared spectroscopy system to record from the frontal and parietal cortices of 4.5-year-old children (N = 74) as they completed a colour change-detection VWM task in their homes. Parents were asked to fill in questionnaires on temperament, academic aspirations, home environment and life stress. Children were median-split into a low-performing (LP) and a high-performing (HP) group based on the number of items they could successfully remember during the task. LPs increasingly activated channels in the left frontal and bilateral parietal cortices with increasing load, whereas HPs showed no difference in activation. Our findings suggest that LPs recruited more neural resources than HPs when their VWM capacity was challenged. We employed mediation analyses to examine the association between the difference in activation between the highest and lowest loads and variables from the questionnaires. The difference in activation between loads in the left parietal cortex partially mediated the association between parent-reported stressful life events and VWM performance. Critically, our findings show that the association between VWM capacity, left parietal activation and indicators of life stress is important to understand the nature of individual differences in VWM in pre-school children.
In psychiatry, there has been a growing focus on identifying at-risk populations. For schizophrenia, these efforts have led to the development of early recognition and intervention measures. Despite a similar disease burden, the populations at risk of bipolar disorder have not been sufficiently characterized. Within the BipoLife consortium, we used magnetic resonance imaging (MRI) data from a multicenter study to assess structural gray matter alterations in N = 263 help-seeking individuals from seven study sites. We defined the risk using the EPIbipolar assessment tool as no-risk, low-risk, and high-risk and used a region-of-interest approach (ROI) based on the results of two large-scale multicenter studies of bipolar disorder by the ENIGMA working group. We detected significant differences in the thickness of the left pars opercularis (Cohen’s d = 0.47, p = 0.024) between groups. The cortex was significantly thinner in high-risk individuals compared to those in the no-risk group (p = 0.011). We detected no differences in the hippocampal volume. Exploratory analyses revealed no significant differences in other cortical or subcortical regions. The thinner cortex in help-seeking individuals at risk of bipolar disorder is in line with previous findings in patients with the established disorder and corresponds to the region of the highest effect size in the ENIGMA study of cortical alterations. Structural alterations in prefrontal cortex might be a trait marker of bipolar risk. This is the largest structural MRI study of help-seeking individuals at increased risk of bipolar disorder.
Conduct disorder (CD), a psychiatric disorder characterized by a repetitive pattern of antisocial behaviors, results from a complex interplay between genetic and environmental factors. The clinical presentation of CD varies both according to the individual’s sex and level of callous-unemotional (CU) traits, but it remains unclear how genetic and environmental factors interact at the molecular level to produce these differences. Emerging evidence in males implicates methylation of genes associated with socio-affective processes. Here, we combined an epigenome-wide association study with structural neuroimaging in 51 females with CD and 59 typically developing (TD) females to examine DNA methylation in relation to CD, CU traits, and gray matter volume (GMV). We demonstrate an inverse pattern of correlation between CU traits and methylation of a chromosome 1 region in CD females (positive) as compared to TD females (negative). The identified region spans exon 1 of the SLC25A24 gene, central to energy metabolism due to its role in mitochondrial function. Increased SLC25A24 methylation was also related to lower GMV in multiple brain regions in the overall cohort. These included the superior frontal gyrus, dorsolateral prefrontal cortex, supramarginal gyrus, secondary visual cortex and ventral posterior cingulate cortex, which are regions that have previously been implicated in CD and CU traits. While our findings are preliminary and need to be replicated in larger samples, they provide novel evidence that CU traits in females are associated with methylation levels in a fundamentally different way in CD and TD individuals, which in turn may relate to observable variations in GMV across the brain.

The COVID-19 pandemic has triggered health-related anxiety in ways that undermine peoples’ mental and physical health. Contextual factors such as living in a high-risk area might further increase the risk of health deterioration. Based on the Social Identity Approach, we argue that social identities can not only be local that are characterized by social interactions, but also be global that are characterized by a symbolic sense of togetherness and that both of these can be a basis for health. In line with these ideas, we tested how identification with one’s family and with humankind relates to stress and physical symptoms while experiencing health-related anxiety and being exposed to contextual risk factors. We tested our assumptions in a representative sample (N = 974) two-wave survey study with a 4-week time lag. The results show that anxiety at Time 1 was positively related to stress and physical symptoms at Time 2. Feeling exposed to risk factors related to lower physical health, but was unrelated to stress. Family identification and identification with humankind were both negatively associated with subsequent stress and family identification was negatively associated with subsequent physical symptoms. These findings suggest that for social identities to be beneficial for mental health, they can be embodied as well as symbolic.
Gender stereotypes and self-characterizations in Germany and Nigeria: a cross-cultural comparison
(2021)
Studies on the content of gender stereotypes have been conducted primarily in the United States, while research in other, particularly non-Western, countries is scarce. In this research, we assessed and compared the content of gender stereotypes and self-characterizations in Germany—a Western European country—and Nigeria—a West African country. We asked 403 Germans and Nigerians to rate three target groups (either men in general, women in general, or themselves) on 74 agentic and communal characteristics. We found that Nigerian women were rated as more agentic and more communal than German women, while German men were rated as more communal than Nigerian men, but similarly on agency. On self-characterizations, Nigerian men rated themselves as more communal than German men, but again similarly on agency; Nigerian women rated themselves as more agentic and more communal than German women. Within-country comparisons showed that in Germany, men and women were perceived as similarly agentic and communal, while in Nigeria, men and women were perceived as similarly agentic, but women were perceived as more communal than men (by both others and when rating themselves). Further analysis on individual agentic and communal characteristics, however, showed important differences in stereotypes and self-characterizations of men and women in both countries that were obscured when looking at overall agency and communion. Our results show that gender stereotyping of oneself and others is complex and highlights the impact of culture on people's perceptions of gender.
Point forecasts can be interpreted as functionals (i.e., point summaries) of predictive distributions. We extend methodology for the identification of the functional based on time series of point forecasts and associated realizations. Focusing on state-dependent quantiles and expectiles, we provide a generalized method of moments estimator for the functional, along with tests of optimality under general joint hypotheses of functional relationships and information bases. Our tests are more flexible, and in simulations better calibrated and more powerful than existing solutions. In empirical examples, economic growth forecasts and model output for precipitation are indicative of overstatement in anticipation of extreme events.
As knowledge derived from scientific theory can be helpful for teachers to reflect on their everyday teaching, universities have the challenging task of teaching this knowledge in such a way that pre-service teachers are able to apply it to their later teaching. Case-based learning has emerged as a promising method to foster pre-service teachers’ scientific knowledge application throughout university teacher education. However, surprisingly, empirical evidence for its effectiveness as compared to more traditional instructional interventions in teacher education is still inconclusive, partly being due to constraints concerning the employed comparison groups. The present quasi-experimental study (conducted in the field of classroom management) investigated the effect of studying exactly the same theoretical content with and without text-based cases on scientific knowledge application (as measured by a vignette test) in a sample of 101 pre-service teachers. Although the study found a small advantage for the case-based learning group, it demonstrated that scientific knowledge application may also be effectively fostered in a more traditional instructional course. The findings and their implications are discussed against the background of cognitive theories on inert knowledge and how to prevent it in teacher education.
Objective: Prisoners constitute a high-risk group for suicide, with suicide rates about 5 to 8 times higher than in the general population. The first weeks of imprisonment are a particularly vulnerable time, but there is limited knowledge about the risk factors for either early or late suicide events. Methods: Based on a national total sample of prison suicides in Germany between 2005 and 2017, suicides within the first 2 (4 and 8) weeks after reception into prison were matched by age and penalty length with cases that occurred later. Factors that potentially influence the timing of suicide were investigated. Results: The study has shown that 16.7% (31.5%) of all 390 suicides in German prisons occurred within the first two weeks (two months) of imprisonment. Factors that facilitate adaptation to the prison environment (e.g. prior prison experience) were negatively associated with early suicide events. Factors that hindered the adaptation process (e.g. withdrawal from illicit drugs) were observed more frequently in early suicide events than in late ones. These factors are active at different times of imprisonment. Conclusion: At reception, particular attention should be paid to the following factors associated with early suicide events: widowed marital status, lack of prison experience, and drug dependency.
Narcissistic traits have been linked to structural and functional brain networks, including the insular cortex, however, with inconsistent findings. In this study, we tested the hypothesis that subclinical narcissism is associated with variations in regional brain volumes in insular and prefrontal areas. We studied 103 clinically healthy subjects, who were assessed for narcissistic traits using the Narcissistic Personality Inventory (NPI, 40-item version) and received high-resolution structural magnetic resonance imaging. Voxel-based morphometry was used to analyse MRI scans and multiple regression models were used for statistical analysis, with threshold-free cluster enhancement (TFCE). We found significant (p < 0.05, family-wise error FWE corrected) positive correlations of NPI scores with grey matter in multiple prefrontal cortical areas (including the medial and ventromedial, anterior/rostral dorsolateral prefrontal and orbitofrontal cortices, subgenual and mid-anterior cingulate cortices, insula, and bilateral caudate nuclei). We did not observe reliable links to particular facets of NPI-narcissism. Our findings provide novel evidence for an association of narcissistic traits with variations in prefrontal and insular brain structure, which also overlap with previous functional studies of narcissism-related phenotypes including self-enhancement and social dominance. However, further studies are needed to clarify differential associations to entitlement vs. vulnerable facets of narcissism.
Abstract: The Children's Communication Checklist-2 (CCC-2) is often applied to assess pragmatic language impairment which is highly prevalent in autism spectrum disorder (ASD) and several mental health conditions. We replicated previous findings on the limited applicability of the CCC-2 in clinical samples and the inconsistent findings concerning the factor structure. The aim of the present study was, thus, to develop a concise, simplified, and revised version of the CCC-2 in a large German-speaking sample. Four groups of children and adolescents aged 4 to 17 years were included: ASD (n = 195), intellectual disability (ID, n = 83), diverse mental health conditions (MHC, n = 144) and a typically developing control group (TD, n = 417). We reduced the original number of items from 70 to 39, based on item analysis, exploratory factor analysis and the exclusion of communication-unrelated items. The revised version, CCC-R (α = 0.96), consists of two empirically derived factors: a pragmatic-language (α = 0.96) and a grammatical-semantic-language factor (α = 0.93). All clinical groups (ASD, ID, and MHC) had significantly increased CCC-R total scores, with the highest scores being in the neurodevelopmental disorder groups (ASD and ID). In addition, we found group-specific patterns of elevated pragmatic-language scores in the ASD group and grammatical-semantic scores in the ID group. The CCC-R was comparable to the CCC-2 in distinguishing ASD from the other groups. The CCC-R is proposed as a simplified and easily applied, clinical questionnaire for caregivers, assessing pragmatic language impairments across neurodevelopmental disorders and mental health conditions. Lay Summary: The CCC-2 is a questionnaire designed to identify children who have problems in the social use of language, however, it is limited in its clinical application and exhibits inconsistent factors. We have created a shorter and simpler version of the CCC-2 that we have called the CCC-R which overcomes the previous limitations of the CCC-2. It consists of two subscales: pragmatic language and grammatical-semantic language. The CCC-R can be used as a short and clinically relevant caregiver questionnaire which assesses pragmatic language impairments in children and adolescents.

Physical inactivity is discussed as one of the most detrimental influences for lifestyle-related medical complications such as obesity, heart disease, hypertension, diabetes and premature mortality in in- and outpatients with major depressive disorder (MDD). In contrast, intervention studies indicate that moderate-to-vigorous-intensity physical activity (MVPA) might reduce complications and depression symptoms itself. Self-reported data on depression [Beck-Depression-Inventory-II (BDI-II)], general habitual well-being (FAHW), self-esteem and physical self-perception (FAHW, MSWS) were administrated in a cross-sectional study with 76 in- and outpatients with MDD. MVPA was documented using ActiGraph wGT3X + ® accelerometers and fitness was measured using cardiopulmonary exercise testing (CPET). Subgroups were built according to activity level (low PA defined as MVPA < 30 min/day, moderate PA defined as MVPA 30–45 min/day, high PA defined as MVPA > 45 min/day). Statistical analysis was performed using a Mann–Whitney U and Kruskal–Wallis test, Spearman correlation and mediation analysis. BDI-II scores and MVPA values of in- and outpatients were comparable, but fitness differed between the two groups. Analysis of the outpatient group showed a negative correlation between BDI-II and MVPA. No association of inpatient MVPA and psychopathology was found. General habitual well-being and self-esteem mediated the relationship between outpatient MVPA and BDI-II. The level of depression determined by the BDI-II score was significantly higher in the outpatient low- and moderate PA subgroups compared to outpatients with high PA. Fitness showed no association to depression symptoms or well-being. To ameliorate depressive symptoms of MDD outpatients, intervention strategies should promote habitual MVPA and exercise exceeding the duration recommended for general health (≥ 30 min/day). Further studies need to investigate sufficient MVPA strategies to impact MDD symptoms in inpatient settings. Exercise effects seem to be driven by changes of well-being rather than increased physical fitness.
Culturally adapted cognitive behavioral therapy (CA-CBT) is a well-evaluated, transdiagnostic group intervention for refugees that uses psychoeducation, meditation, and stretching exercises. In the current study, we added problem-solving training to CA-CBT and evaluated this treatment (i.e., CA-CBT+) in a randomized controlled pilot trial with a sample of Farsi-speaking refugees. Participants (N = 24) were male refugees diagnosed with DSM-5 PTSD, major depressive disorder, and anxiety disorders who were randomly assigned to either a treatment or waitlist control (WLC) condition. Treatment components were adapted both to the specific cultural background and the current social problems of asylum seekers. Assessments were performed pretreatment, 12-weeks posttreatment, and 1-year follow-up. The primary treatment outcome was the General Health Questionnaire (GHQ-28); secondary outcome measures included the Posttraumatic Stress Disorder Checklist, Patient Health Questionnaire, Somatic Symptom Scale, World Health Organization Quality of Life, and Emotion Regulation Scale. Eleven of 12 participants were randomized to CA-CBT+ completed treatment. Based on intent-to-treat data, large between-group effect sizes were seen at posttreatment in the GHQ-28, d = 3.0, and for most secondary outcome measures. Improvements for individuals in the treatment group decreased at 1-year follow-up, but effect sizes demonstrated continued large improvements on all measures as compared to pretreatment levels. In summary, CA-CBT+ led to large improvements in general psychopathological distress and quality of life, which were maintained in the long term. In addition, the dropout rate was very low, with delivery in group format. Thus, problem-solving training appears to be a promising addition to CA-CBT.
Beneficial acute effects of resistance exercise on cognitive functions may be modified by exercise intensity or by habitual physical activity. Twenty-six participants (9 female and 17 male; 25.5 ± 3.4 years) completed four resistance exercise interventions in a randomized order on separate days (≥48 h washout). The intensities were set at 60%, 75%, and 90% of the one repetition maximum (1RM). Three interventions had matched workloads (equal resistance*nrepetitions). One intervention applied 75% of the 1RM and a 50% reduced workload (resistance*nrepetitions = 50%). Cognitive attention (Trail Making Test A—TMTA), task switching (Trail Making Test B—TMTB), and working memory (Digit Reading Spans Backward) were assessed before and immediately after exercise. Habitual activity was assessed as MET hours per week using the International Physical Activity Questionnaire. TMTB time to completion was significantly shorter after exercise with an intensity of 60% 1RM and 75% 1RM and 100% workload. Friedman test indicated a significant effect of exercise intensity in favor of 60% 1RM. TMTA performance was significantly shorter after exercise with an intensity of 60% 1RM, 90% 1RM, and 75% 1RM (50% workload). Habitual activity with vigorous intensity correlated positively with the baseline TMTB and Digit Span Forward performance but not with pre- to post-intervention changes. Task switching, based on working memory, mental flexibility, and inhibition, was beneficially influenced by acute exercise with moderate intensity whereas attention performance was increased after exercise with moderate and vigorous intensity. The effect of regular activity had no impact on acute exercise effects.
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.
Background: Visual exploration in autism spectrum disorder (ASD) is characterized by attenuated social attention. The underlying oculomotor function during visual exploration is understudied, whereas oculomotor function during restricted viewing suggested saccade dysmetria in ASD by altered pontocerebellar motor modulation. Methods: Oculomotor function was recorded using remote eye tracking in 142 ASD participants and 142 matched neurotypical controls during free viewing of naturalistic videos with and without human content. The sample was heterogenous concerning age (6–30 years), cognitive ability (60–140 IQ), and male/female ratio (3:1). Oculomotor function was defined as saccade, fixation, and pupil-dilation features that were compared between groups in linear mixed models. Oculomotor function was investigated as ASD classifier and features were correlated with clinical measures. Results: We observed decreased saccade duration (∆M = −0.50, CI [−0.21, −0.78]) and amplitude (∆M = −0.42, CI [−0.12, −0.72]), which was independent of human video content. We observed null findings concerning fixation and pupil-dilation features (POWER = .81). Oculomotor function is a valid ASD classifier comparable to social attention concerning discriminative power. Within ASD, saccade features correlated with measures of restricted and repetitive behavior. Conclusions: We conclude saccade dysmetria as ASD oculomotor phenotype relevant to visual exploration. Decreased saccade amplitude and duration indicate spatially clustered fixations that attenuate visual exploration and emphasize endogenous over exogenous attention. We propose altered pontocerebellar motor modulation as underlying mechanism that contributes to atypical (oculo-)motor coordination and attention function in ASD.
Development and preliminary validation of the Emotions while Learning an Instrument Scale (ELIS)
(2021)
Learning to play a musical instrument is associated with different, partially conflicting emotions. This paper describes the development and psychometric properties of the Emotions while Learning an Instrument Scale (ELIS). In a longitudinal study with 545 German elementary school children factorial structure and psychometric properties were evaluated. Exploratory and confirmatory factor analyses confirmed a two-factor solution measuring Positive musical Emotions while Learning an Instrument (PELI) and Negative Emotions while Learning an Instrument (NELI). Both subscales yielded scores with adequate internal reliability (Cronbach’s α = .74, .86) and relatively stable retest reliabilities over 18 months (r = .11 -.56). Preliminary evidence of congruent and divergent validity of the subscales is provided. Implications for future research of musical emotional experiences in children are discussed.
Background: Misconceptions about ADHD stigmatize affected people, reduce credibility of providers, and prevent/delay treatment. To challenge misconceptions, we curated findings with strong evidence base. Methods: We reviewed studies with more than 2000 participants or meta-analyses from five or more studies or 2000 or more participants. We excluded meta-analyses that did not assess publication bias, except for meta-analyses of prevalence. For network meta-analyses we required comparison adjusted funnel plots. We excluded treatment studies with waiting-list or treatment as usual controls. From this literature, we extracted evidence-based assertions about the disorder. Results: We generated 208 empirically supported statements about ADHD. The status of the included statements as empirically supported is approved by 80 authors from 27 countries and 6 continents. The contents of the manuscript are endorsed by 366 people who have read this document and agree with its contents. Conclusions: Many findings in ADHD are supported by meta-analysis. These allow for firm statements about the nature, course, outcome causes, and treatments for disorders that are useful for reducing misconceptions and stigma.
Chemosensory impairments have been established as a specific indicator of COVID-19. They affect most patients and may persist long past the resolution of respiratory symptoms, representing an unprecedented medical challenge. Since the SARS-CoV-2 pandemic started, we now know much more about smell, taste, and chemesthesis loss associated with COVID-19. However, the temporal dynamics and characteristics of recovery are still unknown. Here, capitalizing on data from the Global Consortium for Chemosensory Research (GCCR) crowdsourced survey, we assessed chemosensory abilities after the resolution of respiratory symptoms in participants diagnosed with COVID-19 during the first wave of the pandemic in Italy. This analysis led to the identification of two patterns of chemosensory recovery, partial and substantial, which were found to be associated with differential age, degrees of chemosensory loss, and regional patterns. Uncovering the self-reported phenomenology of recovery from smell, taste, and chemesthetic disorders is the first, yet essential step, to provide healthcare professionals with the tools to take purposeful and targeted action to address chemosensory disorders and their severe discomfort.
Background: Bipolar disorder is associated with circadian disruption and a high risk of suicidal behavior. In a previous exploratory study of patients with bipolar I disorder, we found that a history of suicide attempts was associated with differences between winter and summer levels of solar insolation. The purpose of this study was to confirm this finding using international data from 42% more collection sites and 25% more countries. Methods: Data analyzed were from 71 prior and new collection sites in 40 countries at a wide range of latitudes. The analysis included 4876 patients with bipolar I disorder, 45% more data than previously analyzed. Of the patients, 1496 (30.7%) had a history of suicide attempt. Solar insolation data, the amount of the sun’s electromagnetic energy striking the surface of the earth, was obtained for each onset location (479 locations in 64 countries). Results: This analysis confirmed the results of the exploratory study with the same best model and slightly better statistical significance. There was a significant inverse association between a history of suicide attempts and the ratio of mean winter insolation to mean summer insolation (mean winter insolation/mean summer insolation). This ratio is largest near the equator which has little change in solar insolation over the year, and smallest near the poles where the winter insolation is very small compared to the summer insolation. Other variables in the model associated with an increased risk of suicide attempts were a history of alcohol or substance abuse, female gender, and younger birth cohort. The winter/summer insolation ratio was also replaced with the ratio of minimum mean monthly insolation to the maximum mean monthly insolation to accommodate insolation patterns in the tropics, and nearly identical results were found. All estimated coefficients were significant at p < 0.01. Conclusion: A large change in solar insolation, both between winter and summer and between the minimum and maximum monthly values, may increase the risk of suicide attempts in bipolar I disorder. With frequent circadian rhythm dysfunction and suicidal behavior in bipolar disorder, greater understanding of the optimal roles of daylight and electric lighting in circadian entrainment is needed.
Liest man heute, fünfzig Jahre nach der Erstveröffentlichung, Alexander und Margarete Mitscherlichs "Die Unfähigkeit zu trauern", so kann man überrascht werden. Das Buch ist ein Klassiker und sein Titel zum Schlagwort geworden: für die Verzögerung der Vergangenheitsbewältigung, für die Verspätung, mit der sich die Deutschen mit den Verbrechen des Nationalsozialismus auseinandergesetzt haben, für den Unwillen, deren Opfer anzuerkennen. Im Buch liest sich das allerdings etwas anders, denn dass die Deutschen nicht getrauert hätten, bezieht sich nicht primär - wie wir wohl erwarten würden - auf die Opfer
The role of music in second-language (L2) learning has long been the object of various empirical and theoretical inquiries. However, research on whether the effect of background music (BM) on language-related task performance is facilitative or inhibitory has produced inconsistent findings. Hence, we investigated the effect of happy and sad BM on complexity, accuracy, and fluency (CAF) of L2 speaking among intermediate learners of English. A between-groups design was used, in which 60 participants were randomly assigned to three groups with two experimental groups performing an oral L2 English retelling task while listening to either happy or sad BM, and a control group performing the task with no background music. The results demonstrated the happy BM group’s significant outperformance in fluency over the control group. In accuracy, the happy BM group also outdid the controls (error-free clauses, correct verb forms). Moreover, the sad BM group performed better in accuracy than the controls but in only one of its measures (correct verb forms). Furthermore, no significant difference between the groups in syntactic complexity was observed. The study, in line with the current literature on BM effects, suggests that it might have specific impacts on L2 oral production, explained by factors such as mood, arousal, neural mechanism, and the target task’s properties.
Substantial evidence shows that physical activity and fitness play a protective role in the development of stress related disorders. However, the beneficial effects of fitness for resilience to modern life stress are not fully understood. Potentially protective effects may be attributed to enhanced resilience via underlying psychosocial mechanisms such as self-efficacy expectations. This study investigated whether physical activity and fitness contribute to prospectively measured resilience and examined the mediating effect of general self-efficacy. 431 initially healthy adults participated in fitness assessments as part of a longitudinal-prospective study, designed to identify mechanisms of resilience. Self-efficacy and habitual activity were assessed in parallel to cardiorespiratory and muscular fitness, which were determined by a submaximal step-test, hand strength and standing long jump test. Resilience was indexed by stressor reactivity: mental health problems in relation to reported life events and daily hassles, monitored quarterly for nine months. Hierarchical linear regression models and bootstrapped mediation analyses were applied. We could show that muscular and self-perceived fitness were positively associated with stress resilience. Extending this finding, the muscular fitness–resilience relationship was partly mediated by self-efficacy expectations. In this context, self-efficacy expectations may act as one underlying psychological mechanism, with complementary benefits for the promotion of mental health. While physical activity and cardiorespiratory fitness did not predict resilience prospectively, we found muscular and self-perceived fitness to be significant prognostic parameters for stress resilience. Although there is still more need to identify specific fitness parameters in light of stress resilience, our study underscores the general relevance of fitness for stress-related disorders prevention.

To explore and describe attitudes and opinions towards suicidality in healthcare professionals (HCPs) working with oncological patients. Methods: A 48-item online questionnaire was developed and distributed to HCPs working with cancer patients. Three hundred fifty-four answered questionnaires were analyzed. Results: The majority of HCPs reported that they were able to understand why a cancer patient would commit suicide (87.8%) or would seek help from an assisted suicide organization (ASO; 83.9%). The understandable reasons were pain and physical impairments (51.4%), social isolation (19.8%), loss of control and autonomy (18.1%), terminal disease (17.2%), loss of meaning (15.3%), desperation (14.7%), and psychic distress (9.3%). Personal experiences with suicidality lead only 44.8% of HCPs to believe that thereby they would be better able to understand a patients’ wish for suicide. Religion was negatively associated with understanding of suicide and why a cancer patient would seek help from an ASO. Knowledge of suicidality was positively associated with why a cancer patient would seek help from an ASO. Conclusions: There is still little knowledge in oncology about the relation of HCPs’ attitudes toward suicidality in their patients and how those attitudes influence their behavior, especially care and treatment of patients. More research on this topic is needed. It stands to reason that more education about suicidality in cancer patients seems likely to improve understanding and attitudes and thereby influence care for cancer patients.
Objectives: Current treatments for chronic depression have focused on reducing interpersonal problems and negative affect, but paid little attention to promoting prosocial motivation and positive affect. Following this treatment focus, the objective of the present study was to examine whether the combination of metta (Loving Kindness) group meditation and subsequent tailored individual therapy focusing on kindness towards oneself and others (metta-based therapy, MBT) shows greater improvements in depressive symptoms than a wait list control group in patients with chronic depression. Methods: Forty-eight patients with DSM-5 persistent depressive disorder were randomly assigned to MBT or a wait list control condition. Outcome was assessed after group meditation, after subsequent individual therapy, and at 6-month follow-up. The primary outcome measure was an independent blind rating of depressive symptoms at post-test. Secondary outcome included changes in self-reported depression, behavioral activation, rumination, social functioning, mindfulness, compassion, and clinician-rated emotion regulation. Results: Mixed-design analyses showed significant differences between MBT and WLC in changes from pre- to post-test in clinician-rated and self-rated depression, behavioral activation, rumination, social functioning, mindfulness, and emotion regulation. Most of the changes occurred during group meditation and were associated with large effect sizes. Improvements were maintained at 6-month follow-up. Conclusions: The results provide preliminary support for the effectiveness of MBT in treating chronic depression. Trial Registration: ISRCTN, ISRCTN97264476.
Although researchers and practitioners increasingly focus on health promotion in organizations, research has been mainly fragmented and fails to integrate different organizational levels in terms of their effects on employee health. Drawing on organizational climate and social identity research, we present a cascading model of organizational health climate and demonstrate how and when leaders' perceptions of organizational health climate are linked to employee well-being. We tested our model in two multisource studies (NStudy 1 = 65 leaders and 291 employees; NStudy 2 = 401 leader–employee dyads). Results showed that leaders' perceptions of organizational health climate were positively related to their health mindsets (i.e., their health awareness). These in turn were positively associated with their health-promoting leadership behavior, which ultimately went along with better employee well-being. Additionally, in Study 1, the relationship between perceived organizational health climate and leaders' health mindsets was moderated by their organizational identification. High leader identification strengthened the relationship between perceived organizational health climate and leaders' health mindsets. These findings have important implications for theory and practice as they show how the dynamics of an organizational health climate can unfold in organizations and how it is related to employee well-being via the novel concept of health-promoting leadership.
Abstract: Neurophysiological measures of preparation and attention are often atypical in ADHD. Still, replicated findings that these measures predict which patients improve after Neurofeedback (NF), reveal neurophysiological specificity, and reflect ADHD-severity are limited. Methods: We analyzed children’s preparatory (CNV) and attentional (Cue-P3) brain activity and behavioral performance during a cued Continuous Performance Task (CPT) before and after slow cortical potential (SCP)-NF or semi-active control treatment (electromyogram biofeedback). Mixed-effects models were performed with 103 participants at baseline and 77 were assessed for pre-post comparisons focusing on clinical outcome prediction, specific neurophysiological effects of NF, and associations with ADHD-severity. Results: Attentional and preparatory brain activity and performance were non-specifically reduced after treatment. Preparatory activity in the SCP-NF group increased with clinical improvement. Several performance and brain activity measures predicted non-specific treatment outcome. Conclusion: Specific neurophysiological effects after SCP-NF were limited to increased neural preparation associated with improvement on ADHD-subscales, but several performance and neurophysiological measures of attention predicted treatment outcome and reflected symptom severity in ADHD. The results may help to optimize treatment.
Art is always an expression of the unconscious. By archetypal images, the artist addresses in addition to the conscious side also the unconscious side of the reader. For literature, this means the existence of two levels of text- a superficial one on which the conscious and deliberate act takes place, and a deeper, symbolic, expression of unconscious contents. According to Jungian theories of the archetype in literature, the choice of the archetype allows us to draw conclusions on the historical and social environment of the writer, because such images often have a compensatory nature.
We investigated whether dichotomous data showed the same latent structure as the interval-level data from which they originated. Given constancy of dimensionality and factor loadings reflecting the latent structure of data, the focus was on the variance of the latent variable of a confirmatory factor model. This variance was shown to summarize the information provided by the factor loadings. The results of a simulation study did not reveal exact correspondence of the variances of the latent variables derived from interval-level and dichotomous data but shrinkage. Since shrinkage occurred systematically, methods for recovering the original variance were fleshed out and evaluated.
The sudden impact of the COVID-19 pandemic challenged universities to provide students with online teaching and learning settings that were both immediately applicable and supportive of quality learning. This resulted in a broad variety of synchronous and asynchronous online settings of teaching and learning. While some courses balanced both kinds, others offered either predominantly synchronous or asynchronous teaching and learning. In a survey study with students (N=3,056) and teachers (N=396) from a large German university, we explored whether a predominance of synchronous or asynchronous teaching and learning settings in higher education was associated with certain student experiences and outcomes. Additionally, we examined how well these two types of teaching and learning settings support students’ basic psychological needs for autonomy, competence, and relatedness proposed by self-determination theory (SDT). Data were collected after the first online semester due to the COVID-19 pandemic. The results imply that from the students’ perspective, the teaching methods involved in the two settings of teaching and learning differ with regard to their potential to support social interaction and to support basic psychological needs as proposed by SDT. Students who studied mostly in synchronous settings reported more peer-centered activities such as feedback in comparison to students in mostly asynchronous settings. In contrast, teachers perceived fewer differences between teaching methods in synchronous and asynchronous settings, especially regarding feedback activities. Further, students in mostly synchronous settings reported greater support of their basic psychological needs for competence support and relatedness as well as a greater overall satisfaction with the online term compared to students in mostly asynchronous settings. Across all students, greater fulfillment of psychological needs and higher technology acceptance coincided with outcomes that are more favorable. Implications for the post-pandemic classroom are drawn.
With our research, we contribute to the research on proactive work behavior in two ways. First, we examine a person's gender as a boundary condition for proactive behavior at work. Based on social role theory, we argue that women are less likely to receive credit for showing personal initiative (PI) than men. Second, we examine agency and communion as underlying mechanisms that translate PI into a person's evaluation and drive backlash effects. The hypotheses were tested in two complementary experimental studies (Study 1; N = 114, Study 2: N = 163) using simulated job interviews. Our results show that PI relates to better evaluations (likeability, perceived competence, performance evaluations, expected success and hireability) of the job applicant and that these effects are mediated by agency and communion. Further, we find backlash effects for women high in agency and men high in communion on likeability (Study 2). The implications of these results for organizations and future research are discussed.
Interpretation bias and dysfunctional social assumptions are proposed to play a pivotal role in the development and maintenance of social phobia (SP), especially in youth. In this study, we aimed to investigate disorder-specific implicit assumptions of rejection and implicit interpretation bias in youth with severe, chronic SP and healthy controls (CG). Twenty-seven youth with SP in inpatient/day-care treatment (M age = 15.6 years, 74% female) and 24 healthy controls (M age = 15.7 years, 54% female) were included. The Implicit Association Test (IAT) and the Affect Misattribution Procedure (AMP) were completed to assess implicit assumptions and interpretation bias related to the processing of social and affective stimuli. No group differences were observed for the IAT controlling for depressive symptoms in the analyses. However, group differences were found regarding interpretation bias (p = .017, η2p = .137). Correlations between implicit scores and explicit questionnaire results were medium to large in the SP group (r =|.28| to |.54|, pall ≤ .05), but lower in the control group (r =|.04| to |.46|, pall ≤ .05). Our results confirm the finding of an interpretation bias in youth SP, especially regarding the implicit processing of faces, whereas implicit dysfunctional social assumptions of being rejected do not seem to be specific for SP. Future research should investigate the causal relationship of assumptions/interpretation bias and SP.
Sprach- und Sprechstörungen kommen bei zahlreichen Kindern vor und werden in der ICD-11 analog zur ICD-10 als Entwicklungsstörungen im Kapitel 6 (Psychische, Verhaltens- und Entwicklungsstörungen) klassifiziert. International sind bislang die ICD-10-Kriterien nicht von allen Professionen, die sich mit Sprach- und Sprechstörungen klinisch oder im Rahmen der Forschung beschäftigen, akzeptiert. Sie werden einerseits als zu wenig differenziert hinsichtlich der unterschiedlichen Sprachkomponenten vonseiten der Linguistik, Sprachtherapie oder Logopädie erlebt. Zum anderen wird die unklare Abgrenzung organisch bedingter Sprach- und Sprechprobleme von der Sprachentwicklungsstörung vonseiten der Medizin teilweise kritisch bewertet. In dem vorliegenden Artikel wird deshalb einerseits die Klassifikation von Sprach- und Sprechproblemen und -störungen in der ICD-11 im Vergleich zur ICD-10 vorgenommen. Wesentlich erscheint hier die in der ICD-11 neu eingeführte Differenzierung in „primäre“ und „sekundäre“ Neuroentwicklungsstörungen. Zum anderen erfolgt aber auch eine Auseinandersetzung mit dem DSM-5 sowie anderen Klassifikationsvorschlägen vonseiten der englischsprachigen Sprachtherapie (CATALISE-2) und der deutschsprachigen Pädaudiologie („phonologische Wahrnehmungsstörung“) sowie der Vorschlag einer Ergänzung der aktuellen ICD-11-Klassifikation hinsichtlich konkreter sprachlicher Einschränkungen bei einem Kind mit Sprachentwicklungsstörung, basierend auf einer ausführlichen Diagnostik. Wir hoffen, mit dem Artikel so den Weg für eine berufsübergreifende Klassifikation von Sprach- und Sprechstörungen nach ICD-11 zu bahnen, damit perspektivisch alle Berufsgruppen, die Diagnostik und Therapie der betroffenen Personen anbieten, eine vergleichbare Terminologie verwenden. Diese vergleichbare Terminologie soll sowohl die klinische Versorgung verbessern als auch die unterschiedlichen Forschungsansätze und -richtungen vergleichbarer machen.
Individual differences in general cognitive ability (i.e., intelligence) have been linked to individual variations in the modular organization of functional brain networks. However, these analyses have been limited to static (time-averaged) connectivity, and have not yet addressed whether dynamic changes in the configuration of brain networks relate to general intelligence. Here, we used multiband functional MRI resting-state data (N = 281) and estimated subject-specific time-varying functional connectivity networks. Modularity optimization was applied to determine individual time-variant module partitions and to assess fluctuations in modularity across time. We show that higher intelligence, indexed by an established composite measure, the Wechsler Abbreviated Scale of Intelligence (WASI), is associated with higher temporal stability (lower temporal variability) of brain network modularity. Post-hoc analyses reveal that subjects with higher intelligence scores engage in fewer periods of extremely high modularity — which are characterized by greater disconnection of task-positive from task-negative networks. Further, we show that brain regions of the dorsal attention network contribute most to the observed effect. In sum, our study suggests that investigating the temporal dynamics of functional brain network topology contributes to our understanding of the neural bases of general cognitive abilities.
Positive psychological coaching (PPC) has emerged as a popular “paradigm” for practitioners interested in the professional development of people. A recent review consolidated the literature on PPC and produced a 5-phase positive psychological coaching model aimed at facilitating professional growth. However, little is known about practically operationalizing each phase of the coaching process (i.e., how to facilitate each phase and which underlying tools and techniques could be employed to do so). As such, the purpose of this systematic review was to address this limitation by (a) determining which coaching tools and techniques are proposed within the coaching literature and (b) classifying the identified tools and techniques into the respective phases of PPC model. The investigation used a two-step approach by conducting a systematic literature review (to identify various PPC tools/techniques) followed by an iterative heuristic classification process (to assign these PPC tools/techniques to a known PPC model). The systematic literature review resulted in 24 peer-reviewed publications on positive psychological coaching, providing 117 different coaching tools that could be condensed into 18 overarching coaching techniques. The iterative classification process showed that most techniques and tools are useful in at least two phases. Interestingly, experts still vary in opinion on the timing and application of these specific techniques and tools within the positive psychological coaching process. This study provides researchers and practitioners with practical guidelines to facilitate a positive psychological coaching process.
This paper investigates self-initiated uses of mobile phones (such as texting or making a call) in everyday video-recorded conversations among Czech speakers. Using ethnomethodological conversation analysis, it illustrates how participants publicly frame their own device use (for example, by announcements), and how co-present interlocutors respond to it. Previous studies have described how participants manage two concurrent communicative involvements, but have not provided detailed sequential descriptions of how device use can be negotiated and accounted for. This study shows that mobile device use in co-presence is not a priori problematic (or vice versa). Instead, participants frame their technology use in different ways according to various features of the social situation they treat as momentarily relevant. These features include the course of the conversation and how the device use relates to it, the overall participation framework and the opacity of the device use for co-present others.
Hintergrund: Das Kindesalter wurde bei der Entwicklung von wirksamen Präventions- und Interventionsprogrammen bei Computerspiel- und Internetabhängigkeit bisher kaum berücksichtigt. PROTECTdissonanz wurde daher als 1-stündiges dissonanzbasiertes universelles Primärpräventionsprogramm für die Klassenstufe 5 konzipiert. Die vorliegende Pilotstudie überprüft die unmittelbaren Effekte der Dissonanzinduktion auf die Einstellung zum Gaming. Methodik: In einem einarmigen A+B-Design mit drei Messzeitpunkten (T0, T1, T2) wurde die Einstellung zum Gaming anhand des Gaming Attitude Test (GAT) erfasst. In die Baselinesequenz (Sequenz A, T0 bis T1, Teilstichprobe) wurden N = 83 Schüler_innen eingeschlossen (Alter: M = 10.27; SD = 0.48) und in die Interventionssequenz (Sequenz B, T1 bis T2, Gesamtstichprobe) N = 200 Schüler_innen (Alter: M = 10.24; SD = 0.47). Akzeptanz und Zufriedenheit wurden nach der Intervention erfasst. Ergebnisse: Hierarchisch lineare Wachstumsmodelle zeigten eine signifikante Reduktion der GAT-Symptome durch die Intervention, sowohl im Gesamtwert des GAT als auch auf der Subskala „Bagatellisierung negativer Konsequenzen“. Im natürlichen Verlauf (Baselinesequenz A) zeigten sich keine Veränderungen. Die Schüler_innen bewerteten PROTECTdissonanz zudem mit einer hohen Zufriedenheit. Schlussfolgerungen: Eine kurze, gezielte übung zur Dissonanzinduktion zeigt unmittelbare Effekte auf ein Einstellungsmaß zum Gaming. Zur Weiterverfolgung dieses vielversprechenden Ansatzes sollte in künftigen Studien untersucht werden, ob sich eine verringerte Bagatellisierung negativer Konsequenzen von Gaming im Sinne der kognitiven Dissonanztheorie auch tatsächlich in einer Verhaltensänderung widerspiegelt.
The strengths use scale: psychometric properties, longitudinal invariance and criterion validity
(2021)
Strengths use is an essential personal resource to consider when designing higher-educational programs and interventions. Strengths use is associated with positive outcomes for both the student (e.g., study engagement) and the university (e.g., academic throughput/performance). The Strengths Use Scale (SUS) has become a popular psychometric instrument to measure strengths use in educational settings, yet its use has been subjected to limited psychometric scrutiny outside of the U.S. Further, its longitudinal stability has not yet been established. Given the wide use of this instrument, the goals of this study were to investigate (a) longitudinal factorial validity and the internal consistency of the scale, (b) its equivalence over time, and (c) criterion validity through its relationship with study engagement over time. Data were gathered at two-time points, 3 months apart, from a sample of students in the Netherlands (n = 360). Longitudinal confirmatory factor analyses showed support for a two-factor model for overall strengths use, comprised of Affinity for Strengths and Strengths Use Behaviors. The SUS demonstrated high levels of internal consistency at both the lower- and upper bound limits at both time points. Further, strict longitudinal measurement invariance was established, which confirmed the instrument's temporal stability. Finally, criterion validity was established through relating strengths use to study engagement at different time stamps. These findings support the use of the SUS in practice to measure strengths use and to track the effectiveness of strengths use interventions within the higher education sector.
In zwei Studien untersucht das Psychologen-Team um Prof. Ulrich Stangier, wie sich die Corona-Pandemie auf die psychische Gesundheit auswirkt. Beim sogenannten „Cave-Syndrom” wird danach gefragt, ob sich Menschen auch noch nach der Phase, in der das Social Distancing eine weitere Ausbreitung des Virus verhindern sollte, dem sozialen Miteinander weiterhin entziehen, während bei „Long COVID” die Auswirkungen einer Corona-Infektion auf das Erleben und Befinden eines Genesenen untersucht werden.
As knowledge derived from scientific theory can be helpful for teachers to reflect on their everyday teaching, universities have the challenging task of teaching this knowledge in such a way that pre-service teachers are able to apply it to their later teaching. Case-based learning has emerged as a promising method to foster pre-service teachers’ scientific knowledge application throughout university teacher education. However, surprisingly, empirical evidence for its effectiveness as compared to more traditional instructional interventions in teacher education is still inconclusive, partly being due to constraints concerning the employed comparison groups. The present quasi-experimental study (conducted in the field of classroom management) investigated the effect of studying exactly the same theoretical content with and without text-based cases on scientific knowledge application (as measured by a vignette test) in a sample of 101 pre-service teachers. Although the study found a small advantage for the case-based learning group, it demonstrated that scientific knowledge application may also be effectively fostered in a more traditional instructional course. The findings and their implications are discussed against the background of cognitive theories on inert knowledge and how to prevent it in teacher education.
Uneindeutiger Verlust unterscheidet sich von eindeutigem Verlust durch Tod dadurch, dass der Verlust nicht sicher ist, da Verbleib und Schicksal der verlorenen Person unklar sind (physischer uneindeutiger Verlust; die Person wird vermisst) oder aber da die Person zwar physisch präsent, aber psychisch abwesend ist (psychologischer uneindeutiger Verlust, bspw.
durch Alzheimer; Boss, 1999, 2006). Klinische Fallberichte legen nahe, dass die Uneindeutigkeit des Verlusts einer geliebten Person den Trauerprozess erschwert, doch mangelt es an systematischen Studien. Die vorliegende Studie ist die erste, die beide Arten uneindeutigen Verlusts systematisch mit Verlust durch Tod unter nicht-gewaltsamen Umständen vergleicht. Publikation 1 und 2 zielen darauf, ein multidimensionales Verständnis davon zu gewinnen, wie die Uneindeutigkeit eines Verlusts dessen Verarbeitung beeinflusst. Untersucht wurde auch, ob die Auswirkungen der Uneindeutigkeit eines Verlusts sich auf die Erzählung des Verlusts selbst beschränkt oder sich auch auf andere Erinnerungen auswirkt. Artikel 3 geht einen Schritt weiter und untersucht protektive Faktoren, die ein erfolgreiches Verstehen und adaptive Folgen befördern können. Alle drei Veröffentlichungen basieren auf derselben Studie, in der je 30 Erwachsene mit physischem sowie mit psychologischem uneindeutigen Verlust untersucht wurden sowie weitere 30 mit eindeutigem Verlust eines Elternteils durch Tod (N = 90). Alle Teilnehmenden erzählten fünf Erinnerungen (n = 450), einmal eine offene Erzählung des Verlusts sowie je eine Erzählung eines spezifischen Ereignisses, nämlich eines verlustbezogenen Ereignisses, eines traurigen Ereignisses, eines Wendepunkt-Erlebnisses sowie eines selbstdefinierenden Erlebnisses. Zudem füllten sie symptombezogene Fragebögen aus. Insgesamt wurden neun Kodiermanuale auf die Erzählungen angewendet, um zu erfassen, wie Verluste verarbeitet und bewältigt werden. Der erste Artikel zeigt, dass Personen mit uneindeutigem Verlust, verglichen mit Personen mit eindeutigem Verlust, zwar nicht mehr in dem Verlusterlebnis aufgehen, aber doch schlechter mit ihm zurecht kommen. Die Uneindeutigkeit des Verlusts erschwert es, dem Verlust einen Sinn zu verleihen, und lässt seine Folgen negativer erscheinen. Der zweite Artikel zeigt, dass Menschen, die einen uneindeutigen Verlust erlebt haben, diesen sowie selbstdefinierende Erinnerungen mit mehr sogenannten Kontaminations- und weniger Erlösungssequenzen erzählen, und nur das Verlusterlebnis mit weniger Themen der Agentizität und Gemeinschaft, sich aber nicht in traurigen und Wendepunkterzählungen unterscheiden. Diese Gruppenunterschiede waren nicht auf unterschiedliche Symptomausprägungen zurück zu führen. Im dritten Artikel schließlich kann gezeigt werden, dass die relative Häufigkeit von Verknüpfungen zwischen der eigenen Person und einem Lebensereignis sowie ihre Positivität und Veränderungs- versus Stabilitätsbezug damit korrelierte, wie erfolgreich Lehren aus dem Ereignis gezogen werden konnten. Zudem korrelierte eine höhere Schulbildung mit erfolgreicherem Ziehen von Lehren aus den Ereignissen und mit positiveren Implikationen für Erzählende. Schließlich korrelierte die Positivität autobiographischen Urteilens mit weniger verzögerter Trauer. Diese Arbeit stützt zum Teil die von Boss beschriebenen, im Vergleich zu eindeutigen Verlusten schwerwiegenderen Folgen uneindeutigen Verlusts, spricht aber gegen die von Boss behaupteten traumatischen Folgen. Die Uneindeutigkeit eines Verlusts sollte bei der klinischen Behandlung von Trauernden berücksichtigt werden. Allerdings lässt sich aufgrund des Fehlens einer Kontrollgruppe ohne Verlust nicht beurteilen, ob die festgestellten Besonderheiten des Verarbeitens eines Verlusts als unangemessen zu beurteilen sind. Erst longitudinale Studien werden es erlauben, Verarbeitungs- und Bewältigungsprozesse uneindeutigen Verlusts in Erzählungen im Zeitverlauf zu untersuchen.
Background: This article reports reliability, validity, and norms for the German version of the multi-informant questionnaire Inventory of Callous–Unemotional Traits (ICU). Method: The ICU was filled in by nonreferred children aged 13 to 18 years old (n = 645), parents of children aged 6 to 18 years old (n = 1,005), and their teachers (n = 955). Results: Confirmatory factor analysis resulted in a two-factor solution giving the best fit. Still none of the models showed an adequate model-fit applying the chi-square exact fit test. The internal consistency of the parent’s, teacher’s, and self-report version were α = .830, α = .877 and α = .769, respectively. Interrater reliability was moderate. Convergent validity with the Youth Psychopathic Traits Inventory, the externalizing scores of the Youth Self-Report/Child Behavior Checklist, and with the German oppositional Defiant Disorder/Conduct Disorder Rating Scale “FBB-SSV” were good. German norms were calculated. Conclusions: The ICU is a reliable and valid dimensional measure to describe callous–unemotional traits.
The COVID-19 lockdown has significantly disrupted the higher education environment within the Netherlands and led to changes in available study-related resources and study demands of students. These changes in study resources and study demands, the uncertainty and confusion about educational activities, the developing fear and anxiety about the disease, and the implementation of the COVID-19 lockdown measures may have a significant impact on the mental health of students. As such, this study aimed to investigate the trajectory patterns, rate of change, and longitudinal associations between study resources–demands and mental health of 141 university students from the Netherlands before and during the COVID-19 lockdown. The present study employed a longitudinal design and a piecewise latent growth modeling strategy to investigate the changes in study resources and mental health over a 3 month period. The results showed that moderate levels of student resources significantly decreased before, followed by a substantial rate of increase during, lockdown. In contrast, study demands and mental health were reported to be moderate and stable throughout the study. Finally, the growth trajectories of study resources–demands and mental health were only associated before the lockdown procedures were implemented. Despite growing concerns relating to the negative psychological impact of COVID-19 on students, our study shows that the mental health during the initial COVID-19 lockdown remained relatively unchanged.
We wish to make the following correction to the published paper 'Effects of Transient Loss of Vision on Head and Eye Movements during Visual Search in a Virtual Environment'. We have identified a flaw in the implementation of a latency mitigation strategy for our gaze-contingent protocol written in Unity3D. As a result, the maximum latency is now estimated to be 30 ms instead of 15 ms, which should not affect any of the results originally published but should be noted for further reference.
We aimed to assess executive functioning in children after liver transplantation compared with healthy controls and in relation to real-life school performance using the PedsQLTM Cognitive Functioning Scale (CogPedsQL) and the Childrens’ Color Trail Test (CCTT). One hundred and fifty five children (78f, median age 10.4 (1.2–18.3) years) underwent testing with CogPedsQL and/or CCTT 4.9 (0.1–17.0) years after transplantation. Results were compared to those of 296 healthy children (165f, median age 10.0 (2.0–18.0) years). Liver transplanted children displayed significantly reduced scores for cogPedsQL and CCTT1&2 compared to healthy controls. Overall, school performance was lower in patients compared to controls. In both patients and controls, results of CCTT2 and CogPedsQL correlated strongly with school performance. In contrast to controls, school performance in patients correlated with the level of maternal but not paternal primary education degree (r = −0.21, p = 0.03). None of the patient CCTT or CogPedsQL test results correlated with parental school education. Conclusion: CogPedsQL and CCTT 1&2 were easily applicable in children after OLT and revealed reduced executive functioning compared to controls. Results reflect real life school performance. The association of parental education with school performance is reduced in transplanted children, which possibly indicates the overriding impact of transplant-associated morbidity on cognitive outcomes.
The pathophysiological role of neural autoantibodies in acute psychotic disorders is receiving increased attention. However, there is still an ongoing debate, whether predominantly psychotic manifestations of autoimmune encephalitides exist that may remain undetected and, thus, untreated. Furthermore, it is discussed if such conditions can be diagnosed based on serum antibody results or if a reliable diagnosis requires additional cerebrospinal fluids (CSF) results. In this study, we screened pairs of serum and CSF samples from antipsychotic-naïve individuals with first-episode schizophrenic psychosis (FEP, n = 103), clinical high risk for psychosis (CHR, n = 47), and healthy volunteers (HV, n = 40) for eight different antibodies against various antigens that have been shown to be associated with autoimmune encephalitides: N-methyl-D-aspartate receptor (NMDAR, NR1 subunits only), glutamic acid decarboxylase (GAD65), leucine-rich glioma inactivated protein 1 (LGI1), contactin-associated protein-like 2 protein (CASPR2), α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor (AMPAR) subunit 1, AMPAR subunit 2, γ-aminobutyric acid-B receptors (GABABR), and glycine receptors. All patients were within the norm with regards to a careful neurological examination, a magnetic resonance imaging (MRI) of the brain, an electroencephalogram (EEG), and routine blood pathology. All CSF samples were autoantibody-negative. In three serum samples of individuals with FEP, we detected low-titer CASPR2 immunoglobulin (Ig) G antibodies (≤1:160, n = 2) and non-IgG antibodies against NMDAR (n = 1) (overall serum-autoantibody prevalence in FEP: 2.91%). However, the IgG titers were below the laboratory cut-off defined for positivity, and non-IgG antibodies are of no clinical relevance. This suggests that there were no cases of autoimmune encephalitis in our cohort. Our results highlight the importance and the high specificity of CSF analysis to reliably detect autoantibodies. They confirm the hypothesis that pure psychotic manifestations of antibody-associated autoimmune encephalitides without any additional neuropsychiatric findings are very rare. However, special attention must be paid to those presenting with atypical mental illnesses with additional neurological symptoms, evidence of clinically-significant cognitive involvement, profound sleep-wake perturbations, seizures, electroencephalographic, or magnetic resonance imaging pathologies to be able to identify cases with autoimmune-mediated psychiatric syndromes.

Feasibility of present-centered therapy for prolonged grief disorder: results of a pilot study
(2021)
Present-centered therapy (PCT) was originally developed as a strong comparator for the non-specific effects of psychotherapy in the treatment of posttraumatic stress disorder. PCT qualifies as a not strictly supportive treatment as it is structured and homework is assigned between sessions. It does not focus on cognitive restructuring or exposure. A growing body of literature supports its beneficial effects. For example, it demonstrated only slightly inferior effect sizes and lower dropout rates compared to that of trauma-focused cognitive behavioral therapy in several trials with patients suffering from posttraumatic stress disorder. The current study is the first to evaluate the feasibility and the treatment effects of PCT in adults with prolonged grief disorder (PGD). Meta-analyses on psychotherapy for PGD have yielded moderate effect sizes. N = 20 individuals suffering from PGD were treated with PCT by novice therapists as part of a preparation phase for an upcoming RCT in an outpatient setting. Treatment consisted of 20–24 sessions á 50 min. All outcomes were assessed before treatment, at post-treatment, and at the 3-month follow-up. The primary outcome, PGD symptom severity, was assessed using the Interview for Prolonged Grief-13. Secondary outcomes were self-reported PGD severity, depression, general psychological distress, and somatic symptom severity. Furthermore, therapists evaluated their experiences with their first PCT patient and the treatment manual. In intent-to-treat analyses of all patients we found a significant decrease in interview-based PGD symptom severity at post-treatment (d = 1.26). Decreases were maintained up to the 3-month follow-up assessment (d = 1.25). There were also significant decreases in self-reported PGD symptoms, depression, and general psychological distress. No changes were observed for somatic symptoms. The completion rate was 85%. Therapists deemed PCT to be a learnable treatment program that can be adapted to the patient's individual needs. The preliminary results of PCT as a treatment for PGD demonstrate large effects and indicate good feasibility in outpatient settings. The treatment effects were larger than those reported in meta-analyses. Thus, PCT is a promising treatment for PGD. Possible future research directions are discussed.
Working memory capacity (WMC) and fluid intelligence (Gf) are highly correlated, but what accounts for this relationship remains elusive. Process-overlap theory (POT) proposes that the positive manifold is mainly caused by the overlap of domain-general executive processes which are involved in a battery of mental tests. Thus, executive processes are proposed to explain the relationship between WMC and Gf. The current study aims to (1) achieve a relatively purified representation of the core executive processes including shifting and inhibition by a novel approach combining experimental manipulations and fixed-links modeling, and (2) to explore whether these executive processes account for the overlap between WMC and Gf. To these ends, we reanalyzed data of 215 university students who completed measures of WMC, Gf, and executive processes. Results showed that the model with a common factor, as well as shifting and inhibition factors, provided the best fit to the data of the executive function (EF) task. These components explained around 88% of the variance shared by WMC and Gf. However, it was the common EF factor, rather than inhibition and shifting, that played a major part in explaining the common variance. These results do not support POT as underlying the relationship between WMC and Gf.
Bisherige Forschungsergebnisse zeigen, dass auch Frauen sexuellen Kindesmissbrauch begehen und somit eine potentielle Gefahr für das Kindeswohl darstellen können. Aus Deutschland liegen bisher nur regionale oder Studien mit geringer Stichprobengröße vor. Die vorliegende Studie verfolgt das Ziel, eine umfassende Bestandserhebung des sexuellen Kindesmissbrauchs durch Frauen in Deutschland zu dokumentieren. Im Rahmen der vorliegenden Untersuchung wurden zum ersten Mal bundesweit Strafakten von 465 pädokriminellen Frauen ausgewertet, die in den letzten 30 Jahren nach §§174, 176, 180 oder 182 des StGB verurteilt wurden. Die standardisierte Analyse umfasst 185 Variablen und 54 selbst definierte Skalen. Die Ergebnisse zeigen, dass eine pädokriminelle Frau durchschnittlich 33 Jahre alt ist, zumeist in einer Ehe in einer Kleinstadt lebt und häufig keiner beruflichen Tätigkeit nachgeht. Sie ist eine Mittäterin, handelt überwiegend aus Abhängigkeit zu ihrem männlichen Komplizen heraus, zu dem sie eine intime Beziehung pflegt und missbraucht mehrheitlich weibliche Opfer (Verhältnis fast 2:1). Beinahe die Hälfte der 614 Opfer, zu denen Informationen vorlagen, waren leibliche Kinder der Täterinnen und rund jedes sechste Kind stammte vom männlichen Mittäter.
Diese Dissertation befasst sich mit Validierungsstrategien von Tests zur Erfassung studentischer Kompetenzen. Kompetenzen von Studierenden werden zu verschiedenen Zwecken erhoben. Dies beginnt beim Eintritt in das Studium durch Zulassungstests und wird im Studium fortgesetzt z.B. durch Tests zur Zertifizierung von Kompetenz (Benotung von Leistung) oder zur Zuteilung auf bestimmte Kurse (Einteilung in Sprachniveaus). Neben diesen internen Tests zur Erfassung studentischer Kompetenzen werden auch externe Tests genutzt um etwa die Lehre zu verbessern (Evaluation von Veranstaltungen). Die mit dem Einsatz von Tests verbundenen Konsequenzen können sowohl für Studierende als auch Lehrpersonen und Entscheidungsträger*innen schwerwiegend sein. Daher sollten Tests wissenschaftlichen Gütekriterien genügen.
Das wichtigste Kriterium für die Beurteilung von wissenschaftlichen Tests ist Validität. In dieser Dissertation wird ein argumentationsbasiertes Validierungsansatz verfolgt. In diesem wird nicht die Validität eines Tests untersucht, sondern die Plausibilität der Interpretation beurteilt, die mit den Testwerten verbunden ist. Bislang fehlt jedoch für viele der wissenschaftlichen Tests für den deutschen Hochschulbereich ein auf die Testwertinterpretation abgestimmtes Validitätskonzept.
In dieser Arbeit wird ein Validierungsschema vorgestellt, in das übliche Testnutzen der Erfassung studentischer Kompetenzen an deutschen Hochschulen eingeordnet werden können. Die Einordnung von Testnutzen in das Schema erlaubt die Ableitung von passenden Validitätsevidenzen. Im Fokus stehen das Verhältnis von Test zu 1) Konstrukt, 2) Lehre und 3) beruflichen Anforderungen.
Das Validierungsschema wird angewandt, um Testwertinterpretationen eines empirischen Forschungsprojektes zur Erfassung von Kompetenz in Nachhaltigkeitsmanagement bei Studierenden zu validieren. Der Schwerpunkt dieser Arbeit liegt auf der Validierung der Interpretation, dass die Testwerte von drei nachhaltigkeitsbezogenen Tests Indikatoren für hochschulisch vermittelte Kompetenz in Nachhaltigkeitsmanagement sind. Die Analysen zur Gewinnung von Validitätsevidenzen konzentrieren sich auf die Grundannahme, dass Lernfortschritte in den nachhaltigkeitsbezogenen Tests vorwiegend hochschulisch vermittelt werden. Dafür wurde ein Messwiederholungsdesign mit zwei Gruppen von Studierenden realisiert. Studierende in der Schwerpunktgruppe besuchten ein Semester lang eine reguläre Lehrveranstaltungen mit Bezug zu Nachhaltigkeitsthemen und Nachhaltigkeitsmanagement, Studierende der Kontrollgruppe besuchten keine solchen Lehrveranstaltung. Die Einteilung in Schwerpunkgruppe und Kontrollgruppe erfolgte über Analyse von Modulhandbüchern und verwendeten Lehrmaterialien. Die Ergebnisse zeigen, dass Studierende aus der Schwerpunktgruppe in zwei der drei Tests höhere Lernfortschritte zeigen als Studierende der Kontrollgruppe. Selbstberichte der Studierenden zu hochschulischen und außerhochschulischen Lerngelegenheiten lassen darauf schließen, dass Studierende der Schwerpunkgruppe auch außerhochschulisch ein höheres Interesse an Nachhaltigkeitsthemen zeigen, dies schlägt sich jedoch nicht in höherem Vorwissen in den verwendeten Tests nieder. Insgesamt wird daher für die zwei Tests mit höheren Lernfortschritten in der Schwerpunktgruppe die Interpretation als plausibel bewertet, dass die Testwerte hochschulisch vermittelte Kompetenz in Nachhaltigkeitsmanagement abbilden.
