Outcome Measures
Primary Outcomes (2)
Changes in brain neural activity during the social reward processing as assessed via fMRI
Whole brain and region of interest (ROI) regression analysis will be used to compare the neural activity of participants in response to social reward task in different treatment groups.
approximately 45 minutes after intranasal administration of oxytocin, or placebo, approximately 5.5h after administration of ATD, or placebo
Changes in the resting state as assessed via fMRI
Resting state activity in the social reward related and decision making brain networks will be compared between the treatment groups
Time Frame: approximately 45 minutes after intranasal administration of oxytocin, or placebo, approximately 5.5h after administration of ATD, or placebo
Secondary Outcomes (3)
Associations with Personalities of subjects
before 30mins ATD or placebo administration
Behavioral performance in decision making task
approximately 4h after administration of ATD, or placebo, before nasal spray
Behavioral performance in social reward related task
approximately 105 minutes after intranasal administration of oxytocin, or placebo, approximately 6.5h after administration of ATD, or placebo
