Summary
In this study, a randomized, placebo-controlled between-subject design is adopted to
investigate the effect of a single-dose of intranasally administered OT on approach-avoidance
related motivational tendencies during the processing of a series of social and non-social,
positively and negatively valenced stimuli. To obtain a behavioral measure of
approach-avoidance tendencies, participants will be able to control the viewing time of the
presented stimuli, by pressing 'up' or 'down' on a keyboard. During stimulus presentation
neurophysiological recordings will be performed to obtain a neural measure of
approach-avoidance motivational tendencies, based on electroencephalographic recordings (EEG:
frontal alpha asymmetry). Also assessments of autonomic arousal, based on skin conductance
recordings will be collected.
