To investigate the effects of the drug MDMA (ecstasy) on impulsive behaviour, investigators carried out a test on former users, current users and those who had never taken the drug. Impulsive behaviours were defined by the researchers as those done quickly, without fully considering the consequences. The participants in the study were asked which of the images (1 to 6) was identical to the original image on the left.
The time and accuracy of their responses were recorded. The results are based on 15 participants per group.
