Oxytocin-induced facilitation of learning in a probabilistic task is associated with reduced feedback- and error-related negativity potentials

What Was Tested

Researchers studied Oxytocin in this randomized controlled trial publication.

The present study aimed to investigate whether oxytocin would influence responses to positive and negative feedback differentially or equivalently.

Why It Was Studied

Feedback evaluation of actions and error response detection are critical for optimizing behavioral adaptation.

Oxytocin can facilitate learning following social feedback but whether its effects vary as a function of feedback valence remains unclear.

Who Took Part

The age groups tagged for this paper are young adults, men only.

How the Study Was Run

In design terms this was a randomized, double-blind, placebo-controlled and crossover study.

The participants were allocated by chance, so the Oxytocin group and the comparison group should start out alike.

As a double-blind Oxytocin study, the assignments were hidden from both participants and investigators until the end.

Some participants received a placebo instead of Oxytocin, giving a reference point.

Each person switched between Oxytocin and the comparison at some point, usually with a gap in between.

What Was Measured

Feedback evaluation of actions and error response detection are critical for optimizing behavioral adaptation.

The subject headings attached to it are Adaptation, Psychological, Conditioning, Psychological, Conflict, Psychological, Drug Monitoring, Electroencephalography, Evoked Potentials and Formative Feedback.

The authors tagged it with the keywords Oxytocin, cognitive conflict, error awareness and learning.
