Social functioning predicts individual changes in EEG microstates following intranasal oxytocin administration: A double‐blind, cross‐over randomized clinical trial Psychophysiology (IF 3.7) Pub Date : 2024-04-10 Miralena I. Tomescu, Stephanie Van der Donck, Emanuela M. Perisanu, Alexandru I. Berceanu, Kaat Alaerts, Bart Boets, Ioana Carcea
Oxytocin (OXT) modulates social behaviors. However, the administration of exogenous OXT in humans produces inconsistent behavioral changes, affecting future consideration of OXT as a treatment for autism and other disorders with social symptoms. Inter‐individual variability in social functioning traits might play a key role in how OXT changes brain activity and, therefore, behavior. Here, we investigated

The hypnotizability-related differences in morpho-functional characteristics of the insula could at least partially account for the differences in interoceptive accuracy (IA) observed between high and low hypnotizable individuals (highs, lows). Our aim was to investigate interoceptive processing in highs, lows, and medium hypnotizable individuals (mediums), who represent most of the population, during

Optimal filters for ERP research I: A general approach for selecting filter settings Psychophysiology (IF 3.7) Pub Date : 2024-01-31 Guanghui Zhang, David R. Garrett, Steven J. Luck
Filtering plays an essential role in event-related potential (ERP) research, but filter settings are usually chosen on the basis of historical precedent, lab lore, or informal analyses. This reflects, in part, the lack of a well-reasoned, easily implemented method for identifying the optimal filter settings for a given type of ERP data. To fill this gap, we developed an approach that involves finding

Teleological reasoning bias is predicted by pupil dynamics: Evidence for the extensive integration account of bias in reasoning Psychophysiology (IF 3.7) Pub Date : 2024-01-28 Martin Jensen Mækelæ, Isabel V. Kreis, Gerit Pfuhl
Teleological reasoning is the tendency for humans to see purpose and intentionality in natural phenomena when there is none. In this study, we assess three competing theories on how bias in reasoning arises by examining performance on a teleological reasoning task while measuring pupil size and response times. We replicate that humans (N = 45) are prone to accept false teleological explanations. Further
