Oxytocin påvirker social perception forskelligt hos mænd og kvinder. I en undersøgelse med 47 deltagere vurderede mænd ansigter mere negativt efter oxytocin, mens kvinder vurderede dem mere positivt. Resultaterne understøtter, at oxytocin har kønsspecifikke effekter på social læring og perception.

Hele abstrakt på originalsprog:
This study aimed to explore how gender influences the effects of the neuropeptide oxytocin on social affective perception and learning, involving forty-seven male and female participants who, after receiving either double-blinded intranasal oxytocin or placebo, judged faces in two tasks: one using a continuous flash suppression paradigm with “unseen” affective stimuli to evaluate faces on competence, trustworthiness, and warmth, and another involving a gossip learning procedure where participants learned affective associations between neutral faces and acts before rating them affectively. Results from both tasks revealed that gender moderated oxytocin’s effects, with male participants in the oxytocin condition rating faces more negatively compared to placebo, while female participants exhibited the opposite trend, rating faces more positively under oxytocin than placebo. These findings add to the emerging research highlighting differential oxytocin effects between men and women, suggesting gender plays a critical role in how oxytocin shapes social perception and learning.
