The main aim of the study is to investigate whether intranasal oxytocin modulates advantageous- and disadvantageous-inequity and whether oxytocin has similar effects on them or not.

Detailed description

The main aim of the study is to investigate whether intranasal oxytocin modulates advantageous- and disadvantageous-inequity and its underlying neural mechanisms and whether oxytocin has similar effects on them or not. A double-blinded, placebo-controled, between-subject design is employed in this study. In a randomized order, a total of 80 healthy males are instructed to self-administrated intranasal spray of oxytocin or placebo. A modified inequity decision-making task starts 45 minutes after treatment with behavioral (fairness rating, preference rating and the choice rate of unequal option) and fMRI data being collected during this task. Personality traits of subjects are assessed using validated Chinese version questionnaires including the Beck Depression Inventory (BDI-II), State-Trait Anxiety Inventory (STAI), Autism Spectrum Quotient (ASQ), Sensitivity to Punishment and Sensitivity to Reward Questionnaire (SPSRQ), Behavioral Inhibition System and Behavioral Activation System Scale (BIS/BAS). Subjects are asked to complete Positive and Negative Affect Schedule (PANAS) when they just arrive, before and after the task.
