NCT02350946

Brief Summary

The purpose of this study is to shed light on the basic neurobiological mechanisms which underlie social information processing in healthy men. More specifically, we intend to examine whether a person's social competence level is related to the patterns of neural activity and his visual search strategies during evaluation of social scenes. Furthermore, it will be assessed whether an oxytocin-driven increase in activity in brain areas relevant to the task will facilitate social information processing and thus enhance task performance. Additionally it will be examined whether oxytocin can facilitate response inhibition in an emotional context.

Conditions

Outcome Measures

Primary Outcomes (2)

  • BOLD response during emotion recognition in contrast with a corresponding control condition.

    In the Social Detection Task, subjects' brain activity when viewing social scenes will be compared to corresponding control scenes in which no people are shown. In the GoNoGo Task several emotional conditions will be compared to a neutral control condition.

    (Day 1: oxytocin, Day: 14:placebo, or vice versa [counterbalanced])

  • BOLD response during response inhibition (Emotional Go/ Nogo) in contrast with a corresponding control condition.

    Brain activation during NoGo trials will be compared to brain activation during Go trials from the same emotional condition.

    (Day 1: oxytocin, Day: 14:placebo, or vice versa [counterbalanced])

Secondary Outcomes (7)

  • Serum levels of Oxytocin

    (Day 1: oxytocin, Day: 14:placebo, or vice versa [counterbalanced])

  • Serum levels of Prolaktin

    (Day 1: oxytocin, Day: 14:placebo, or vice versa [counterbalanced])

  • Serum levels of Cortisol

    (Day 1: oxytocin, Day: 14:placebo, or vice versa [counterbalanced])

  • Total length of fixations on areas of interest (AOIs) assessed via eye-tracking

    (Day 1: oxytocin, Day: 14:placebo, or vice versa [counterbalanced])

  • Number of fixations on areas of interest (AOIs) assessed via eye-tracking

    (Day 1: oxytocin, Day: 14:placebo, or vice versa [counterbalanced])

  • +2 more secondary outcomes
