Descriptive Information
Brief Title  ICMJE Effects of MDMA and Methylphenidate on Social Cognition
Official Title  ICMJE Effects of MDMA (Ecstasy) and Methylphenidate (Ritalin) on Social Cognition
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.
