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 16. Jahrestagung DeLFI 2018 der Fachgruppe eLearning der Gesellschaft für Informatik e. V. findet vom 10. bis 13.September 2018 an der Johann Wolfgang Goethe – Universität, Frankfurt am Main statt, gemeinsam mit der 8. Tagung für Hochschuldidaktik der Informatik HDI 2018. ...
Our ability to select relevant information from the environment is limited by the resolution of attention – i.e., the minimum size of the region that can be selected. Neural mechanisms that underlie this limit and its development are not yet understood. Functional magnetic resonance imaging (fMRI) was performed during an object tracking task in 7- and 11-year-old children, and in young adults. Object tracking activated canonical fronto-parietal attention systems and motion-sensitive area MT in children as young as 7 years. Object tracking performance improved with age, together with stronger recruitment of parietal attention areas and a shift from low-level to higher-level visual areas. Increasing the required resolution of spatial attention – which was implemented by varying the distance between target and distractors in the object tracking task – led to activation increases in fronto-insular cortex, medial frontal cortex including anterior cingulate cortex (ACC) and supplementary motor area, superior colliculi, and thalamus. This core circuitry for attentional precision was recruited by all age groups, but ACC showed an age-related activation reduction. Our results suggest that age-related improvements in selective visual attention and in the resolution of attention are characterized by an increased use of more functionally specialized brain regions during the course of development.
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.
Die Erfahrung, "…dass alles auch ganz anders sein könnte" ist die wohl wichtigste Erfahrung in Bildungsprozessen. Die Entdeckung von Möglichkeiten, Perspektivwechseln und transformatorischen Selbst-Bildungsprozessen ist zentral für eine gelungene kulturelle Bildungssituation. (Birgit Mandel, 2005).
Die Hessischen Schülerakademien zur Förderung besonders engagierter und begabter junger Menschen wurden bewusst als ein Unterfangen des Forschenden Lernens gegründet und fühlen sich diesem Leitgedanken im Kontext kultureller Bildung verpflichtet. Dieser Satz klingt zunächst einmal gut und zeitgemäß. Doch was steckt genau dahinter?
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.
