Brief Summary
The study will investigate whether oxytocin administered either intranasally or orally (lingual) (24 international units, IU) can differentially modulate men's neural and behavioral responses to emotional scenes using an implicit emotional paradigm.

Outcome Measures
Primary Outcomes (2)
Compare the effects of oxytocin on neural responses to emotional scenes between intranasal and oral administration routes.
Comparison of whole brain neural (fMRI scanning) activation differences between oral and intranasal oxytocin administration to emotional scenes will be performed using a mixed ANOVA with route (oral/intranasal), treatment (oxytocin/placebo) as between subject factors and valence of emotional scenes (positive/negative/neutral) as within-subject factor, post-hoc comparisons will be conducted to further disentangle the significant interactions observed after the mixed ANOVA.
45~70 minutes after treatment
Compare the effects of oxytocin on behavioral responses to emotional scenes between intranasal and oral administration routes.
Differences in behavioral ratings of valence (1-9 point Self-Assessmen-Manikin (SAM) scale, 1 means very negative, 9 means very positive, 5 means neutral), intensity (1-9 point SAM scale, 1 means mild, 9 means strong), and arousal (1-9 point SAM scale, 1 means not aroused at all, 9 means very aroused) of emotional scene stimuli between oral oxytocin and intranasal oxytocin groups will be examined using mixed ANOVAs, respectively.
70~90 minutes after treatment
Secondary Outcomes (5)
Compare the effect of oxytocin on neural functional connectivity during processing of emotional scenes between intranasal and oral administration routes.
45~70 minutes after treatment
Correlations between neural activation and behavioral effects of intranasal or oral oxytocin during emotional scene processing.
45~90 minutes after treatment
Correlations between functional connectivity and behavioral effects of intranasal or oral oxytocin during emotional scene processing.
45~90 minutes after treatment
Comparison of effects of oxytocin on pre-task resting-state functional connectivity (rsfMRI) between intranasal and oral administration routes.
45~70 minutes after treatment
Mood changes assessed by the Positive Affect Negative Affect Schedule (PANAS) in all treatment groups during the experiment.
0~70 minutes
