A single 75 mg dose of MDMA improved psychomotor performance, including movement speed and tracking in both single and divided attention tasks, but impaired the ability to predict object movement under divided attention, which may indicate impairment of driving-relevant skills. No effect was found on visual search, planning, or semantic memory retrieval. Alcohol 0.5 g/kg was also tested but its effects are not described here. The findings suggest MDMA can both enhance and impair specific cognitive and motor functions relevant to driving.
