Results from this study2

2 results from studies that gave the peptide. 2 results from people.

  1. 01HumanRandomized controlled trialEfficacy outcome

    Oxytocin did not change the brain-response difference between positively and negatively described self-owned objects versus placebo.

    In plain wordsOxytocin did not change brain responses to objects owned by the person themselves, compared with placebo.

    Summary
    self-owned objects framed by positive adjectives elicited more positive-going brain responses than those framed by negative adjectives, irrespective of oxytocin or placebo being administrated
    2 context sentences
    Summary · context
    Thus, oxytocin abolishes other-derogation but does not affect self-enhancement in object evaluation, consistent with the proposal that oxytocin enhances affilliative and approach motivations during social interaction.
    Summary · context
    Brain potentials were recorded in participants who judged the ownership of objects that were described in either positive or negative terms.
  2. 02HumanRandomized controlled trialEfficacy outcome

    Oxytocin reversed the pattern of brain responses to negatively versus positively described other-owned objects, abolishing other-derogation.

    In plain wordsOxytocin removed the usual brain-response bias against objects owned by others, compared with placebo.

    Summary
    Negatively described other-owned objects evoked more positive-going responses than positively described other-owned objects, but the opposite pattern was found with the administration of oxytocin.
