Wie eine "Heilslehre" überzieht der Begriff "Digitalisierung" fast alle Lebensbereiche – natürlich auch den Bildungsbereich. Gerade wir Informatiker*innen sind gefordert, diese Wege der Bildungstransformation mitzugestalten. Wir zusammen mit den Erziehungswissenschaftler*innen und Psychologen*innen müssen identifizieren, aufzeigen und vorbildlich umsetzen, was sinnvoll und möglich ist. Wir sind diejenigen, die die Bedingungen des Gelingens und auch die der Irrwege erforschen und aufzeigen müssen. Digitalisierungswahnsinn brauchen wir nicht!

Die vorliegende Arbeit befasst sich damit, wie die spezifische Durchführung eines besonderen psychologischen Laborexperiments in eine allgemeine, kausale Form übersetzt wird. Anstatt dazu formale Kriterien der Validität heranzuziehen, wird ein experimenteller Forschungsprozess ethnographisch begleitet.
Forschungsgegenstand ist ein Verhaltensexperiment aus der allgemeinen Psychologie zur Trainierbarkeit des Arbeitsgedächtnisses. Im Rahmen der Ethnographie werden teilnehmende Beobachtungen, Interviews und Dokumentensammlung kombiniert eingesetzt. Die Auswertung der Materialien erfolgt mithilfe der Situationsanalyse nach Clarke (2012), einer qualitativen Auswertungsmethode im Anschluss an die Grounded Theory.
In dieser Arbeit wird das Verhalten der Versuchsperson ins Zentrum gerückt, das die Messung in Gang setzt und hält und die Entstehung von zahlenförmigen Daten ermöglicht. Dazu wird in Orientierung an neueren Science & Technology Studies eine begriffliche Systematisierung der Experimentalpraxis aus dem empirischen Material herausgearbeitet, mit dem die Konstruktion und Transformation des Verhaltens der Versuchsperson im Verlauf des Datenerhebungs- Auswertungs- und Interpretationsprozesses beschrieben werden kann.
Die Ergebnisse der Ethnographie legen nahe, dass dieses Verhalten der Versuchsperson - korrespondierend zum kausal verfassten Endprodukt des Experiments - von der komplexen Erhebungssituation abhängig und paradoxerweise gleichzeitig unabhängig ist. Damit wird in Anlehnung an Latour (2002) zwischen konstruktivistischen und objektivistischen Positionen vermittelt. Zudem weisen die erforschten Praktiken die epistemische Stellung der Versuchsperson aus. Diese wird im Anschluss an die Terminologie von Rheinberger (2001/ 2006) als Mischform von epistemischem Ding (Neues) und technischem Ding (Bekanntes) bestimmt.
Erstmalig begrüßen Sie zwei Veranstalter zum Kongress der Deutschen Gesellschaft für Psychologie (DGPs). Im Namen der Goethe-Universität und des DIPF heißen wir Sie zum 51. DGPs-Kongress in Frankfurt herzlich willkommen. Unser diesjähriges Motto "Psychologie gestaltet" stellt die Bedeutung der wissenschaftlichen Psychologie für die Bewältigung individueller und gesellschaftlicher Herausforderungen in den Mittelpunkt. Als Forschende haben wir in vielen Bereichen die Möglichkeit, positiv zur Gestaltung menschlichen Lebens und Zusammenlebens beizutragen. In diesem Sinne freuen wir uns auf einen anregenden Kongress, gestaltet durch die rund 2400 wissenschaftlichen Beiträge aus allen Gebieten der Psychologie. ...
Social identification has been shown to be a protective resource for mental health. In this study, the relationships between social identification and emotional, as well as cognitive symptoms of test anxiety are investigated. Participants were university students diagnosed with test anxiety (N = 108). They completed questionnaires regarding a range of psychopathologic stress symptoms, and their social identification with fellow students and with their study program. Results reveal negative relations between social identification and almost all investigated emotional and cognitive symptoms of test anxiety. Based on this study, interventions could be developed that strengthen the social identity of university students.
Background: Early-life institutional deprivation produces disinhibited social engagement (DSE). Portrayed as a childhood condition, little is known about the persistence of DSE-type behaviours into, presentation during, and their impact on, functioning in adulthood.
Aims: We examine these issues in the young adult follow-up of the English and Romanian Adoptees study.
Method: A total of 122 of the original 165 Romanian adoptees who had spent up to 43 months as children in Ceauşescu's Romanian orphanages and 42 UK adoptees were assessed for DSE behaviours, neurodevelopmental and mental health problems, and impairment between ages 2 and 25 years.
Results: Young adult DSE behaviour was strongly associated with early childhood deprivation, with a sixfold increase for those who spent more than 6 months in institutions. However, although DSE overlapped with autism spectrum disorder and attention-deficit hyperactivity disorder symptoms it was not, in itself, related to broader patterns of mental health problems or impairments in daily functioning in young adulthood.
Conclusions: DSE behaviour remained a prominent, but largely clinically benign, young adult feature of some adoptees who experienced early deprivation.
Even though extensively investigated, the nature of working memory (WM) deficits in patients with schizophrenia (PSZ) is not yet fully understood. In particular, the contribution of different WM sub-processes to the severe WM deficit observed in PSZ is a matter of debate. So far, most research has focused on impaired WM maintenance. By analyzing different types of errors in a spatial delayed response task (DRT), we have recently demonstrated that incorrect yet confident responses (which we labeled as false memory errors) rather than incorrect/not-confident responses reflect failures of WM encoding, which was also impaired in PSZ. In the present study, we provide further evidence for a functional dissociation between confident and not-confident errors by manipulating the demands on WM maintenance, i.e., the length over which information has to be maintained in WM. Furthermore, we investigate whether these functionally distinguishable WM processes are impaired in PSZ. Twenty-four PSZ and 24 demographically matched healthy controls (HC) performed a spatial DRT in which the length of the delay period was varied between 1, 2, 4, and 6 s. In each trial, participants also rated their level of response confidence. Across both groups, longer delays led to increased rates of incorrect/not-confident responses, while incorrect/confident responses were not affected by delay length. This functional dissociation provides additional support for our proposal that false memory errors (i.e., confident errors) reflect problems at the level of WM encoding, while not-confident errors reflect failures of WM maintenance. Schizophrenic patients showed increased numbers of both confident and not-confident errors, suggesting that both sub-processes of WM—encoding and maintenance—are impaired in schizophrenia. Combined with the delay length-dependent functional dissociation, we propose that these impairments in schizophrenic patients are functionally distinguishable.
White matter microstructural changes and episodic memory disturbances in late-onset bipolar disorder
(2018)
Background: Bipolar disorder (BD) has been associated with distributed network disruption, but little is known on how different clinical subtypes, particularly those with an earlier and later onset of disease, are related to connectivity changes in white matter (WM) tracts.
Methods: Diffusion tensor imaging (DTI) and volumetric measures were carried out in early-onset bipolar patients [(EOD) (n = 16)], late-onset bipolar disorder [(LOD)(n = 14)] and healthy controls (n = 32). We also computed ROI analysis of gray matter (GM) and white matter (WM) volumes using the regions with significant group differences in the DTI parameters. Cognitive and behavior measurements were analyzed between groups.
Results: Lower fraction of anisotropy (FA) in the right hemisphere comprising anterior thalamic radiation, fornix, posterior cingulate, internal capsule, splenium of corpus callosum was observed in the LOD in comparison with EOD; additionally, lower FA was also found in the LOD in comparison with healthy controls, mostly in the right hemisphere and comprising fibers of the splenium of the corpus callosum, cingulum, superior frontal gyrus and posterior thalamic radiation; LOD also showed worse episodic memory performance than EOD; no statistical significant differences between mood symptoms, WM and GM volumes were found between BD groups.
Conclusion: Even after correcting for age differences, LOD was associated with more extensive WM microstructural changes and worse episodic memory performance than EOD; these findings suggest that changes in the WM fiber integrity may be associated with a later presentation of BD, possibly due to mechanisms other than neuroprogression. However, these findings deserve replication in larger, prospective, studies.
Purpose: Collaborative care is effective in improving symptoms of patients with depression. The aims of this study were to characterize symptom trajectories in patients with major depression during one year of collaborative care and to explore associations between baseline characteristics and symptom trajectories.
Methods: We conducted a cluster-randomized controlled trial in primary care. The collaborative care intervention comprised case management and behavioral activation. We used the Patient Health Questionnaire-9 (PHQ-9) to assess symptom severity as the primary outcome. Statistical analyses comprised latent growth mixture modeling and a hierarchical binary logistic regression model.
Results: We included 74 practices and 626 patients (310 intervention and 316 control recipients) at baseline. Based on a minimum of 12 measurement points for each intervention recipient, we identified two latent trajectories, which we labeled "fast improvers" (60.5%) and "slow improvers" (39.5%). At all measurements after baseline, "fast improvers" presented higher PHQ mean values than "slow improvers". At baseline, "fast improvers" presented fewer physical conditions, higher health-related quality of life, and had made fewer suicide attempts in their history.
Conclusions: A notable proportion of 39.5% of patients improved only "slowly" and probably needed more intense treatment. The third follow-up in month two could well be a sensible time to adjust treatment to support "slow improvers".
In transferring the concept of flow to the context of fiction reading a new approach to understanding the evolvement of reading pleasure is provided. This study presents the Reading Flow Short Scale (RFSS), the first reading-specific flow measurement tool. The RFSS was applied to 229 readers via online survey after 20 min of reading in self-selected novels. In a systematic analysis of psychometric properties, the RFSS’ factorial structure, reliability, and associations with theoretically related constructs were examined. As expected, the RFSS showed a two-factor structure, positive correlations with variables related to reading pleasure and flow, and an inverted U-shaped association with perceived fit between reader skills and text challenge. Comparisons of confirmatory factor analysis model confirmed that RFSS items loaded on different latent variables than items assessing other narrative engagement concepts, namely presence, identification, suspense, and cognitive mastery, and hence distinctly capture flow states in fiction reading. In sum, our findings indicate that the RFSS is a useful instrument for assessing flow states in fiction reading, thereby enriching the portfolio of measurement instruments in reading research.
