  1. 01HumanRandomized controlled trialEfficacy outcome

    In men and women, oxytocin increased the accuracy of familiarity judgments in a face recognition test versus placebo.

    Summary · context
    In a placebo-controlled, double-blind, between-subject study, participants received either oxytocin or placebo before studying own-race and other-race faces.
  2. 02HumanRandomized controlled trialMechanism

    In men and women, oxytocin effects on familiarity had neural correlates in ERPs for memory encoding and retrieval but not perception.

    In plain wordsIn men and women, oxytocin's memory effect showed up in brain-wave measures of memory, not of perception.

  3. 03HumanRandomized controlled trialEfficacy outcome

    In men, oxytocin impaired recollection judgments in a face recognition test versus placebo; no such effect was reported in women.
