  1. 01HumanRandomized controlled trialEfficacy outcome

    In Chinese male adults, intranasal oxytocin increased the racial in-group bias in the P2 neural response to others' pain expressions compared with placebo.

    In plain wordsIn Chinese men, oxytocin increased the brain's stronger response to the pain of people of their own race, compared with placebo.

    Summary · context
    A fronto-central positive activity at 128-188 ms (P2) was of larger amplitude in response to the pain expressions compared with the neutral expressions of racial in-group members but not of racial out-group members.
    Summary · context
    Event-related brain potentials were recorded in Chinese male adults during race judgments on Asian and Caucasian faces expressing pain or showing a neutral expression after intranasal self-administration of OT or placebo.
  2. 02HumanRandomized controlled trialMechanism

    In Chinese male adults, after oxytocin the racial in-group bias in neural responses correlated with a positive implicit attitude toward racial in-group members.

    In plain wordsIn Chinese men given oxytocin, the stronger brain response to own-race pain was linked to a more positive implicit attitude toward own-race people.
