Kosfeld et al. [119] used a TG experiment to show that intranasal infusions of OXT increase trust in humans (but not in other nonsocial interactions), do not increase risk-taking behavior, and did not change trustees’behavior. Although the mechanism of action of OXT is not clear, evidence suggests that OXT decreases stress responses and anxiety in social interactions, likely modulating the amygdala and anterior cingulate cortex (ACC) activity [117, 120].
