Brief Summary
The purpose of this study is to assess and compare the effects of a single dose of 3,4-methylenedioxymethamphetamine (MDMA)and methylphenidate (MPH) on emotional and social cognition in healthy subjects. The investigators hypothesize that MDMA enhances affective perception for positive and impairs perception for negative emotional stimuli compared to placebo or MPH.
