Oxytocin Effects on the Prosocial Learning

Oxytocin Effects on the Prosocial Learning

To investigate whether intranasal oxytocin (24 IU) treatment can influence prosocial learning behavior in males.

In a double-blind, within-subject, placebo controlled design, investigators plan to investigate the effect of oxytocin treatment on prosocial learning. Before the self-administration, participants need to finish several questionnaires including IRI, AAS, BASBIS, SPSRQ, SES, PTM, STAI, BDI, ASQ and PNAS. They would finish the PANAS again before the scanning.

Participants are informed that they perform the reward learning task either for themselves, another (unknown) person or no one (control). In the probabilistc reward learning task, associations with two stimuli with different reward probabilities are learned via monetary feedback (reward ￥1 or no reward ￥0). After the experiment, participants need to finish the PANAS.
