  1. 01HumanRandomized controlled trialEfficacy outcome

    In healthy men, intranasal oxytocin induced a categorization bias in emotion perception under payoff manipulation compared with placebo.

    In plain wordsIn healthy men, oxytocin shifted how faces were judged when the cost of mistakes changed, compared with placebo.

    Summary
    In contrast, oxytocin had no effect on subjects' confidence rating, indicating that the metacognitive sensitivity can be dissociated from emotion perception.
