Experimental: MDMA, methylphenidate, placebo
Cross-over within-subjects design with all treatment conditions tested in the same subject. This design has 1 arm but two (actually 4) treatment conditions in the same subject.
125 mg per os, single dose
1 hour before MDMA/placebo 60 mg methylphenidate per os, single dose
capsules identical to MDMA or methylphenidate
- Subjective effect during 24 hours [ Time Frame: 24 hours ]subjective effects are repetitively assessed by standardized questionnaires.
- Blood pressure (mmHg)during 10 hours [ Time Frame: 10 hours ]
- Neuroendocrine plasma levels during 10 hours [ Time Frame: 10 hours ]neuroendocrine parameters assessed: prolactin, cortisol, epinephrine, norepinephrine, oxytocin, pro-vasopressin, vasopressin, estrogen,and progesterone
- MDMA plasma levels during 24 hours [ Time Frame: 24 hours ]
- Heart rate (beats/min)) during 10 hours [ Time Frame: 10 ]
- Emotional and cognitive empathy [ Time Frame: 5 hours ]
emotional empathy is going to be assessed by the Multifaceted Empathy Test (MET).
cognitive empathy is going to be assessed by the Facial Emotion Recognition Task and the MET.
- Prosocial behavior [ Time Frame: 5 hours ]Effects on prosociality will be assessed by the Social Value Orientation slide-measurement test.
- Genetic polymorphisms [ Time Frame: assessed after study completion ]Effects of genetic polymorphisms on the response to MDMA
