It aims to investigate the psychological mechanisms of impulsivity and compulsivity in addictive and criminal behaviours. We are currently generating and evaluating a Neuropsychological Computerised Test Battery for impulsivity and compulsivity that can reveal important mechanisms (neuropsychological, neurophysiological and neuroanatomical) and predict dysfunctional behaviours (criminal behaviour and drug use). In addition, they have developed an App to stop using cannabis and tobacco.
