Psychopathy and P3 amplitude: a commentary on Raine.
Raine (1989) reviewed the literature on event-related potentials (ERPs) in psychopathic adults and antisocial adolescents and concluded that findings support an extended sensation-seeking model of psychopathy. Specifically, he suggested that P3 findings were indicative of unusually enhanced attentional processing in psychopaths. It will be argued in this paper that evidence from recent ERP studies is insufficient to challenge notions of information processing deficit in psychopathy, and that an extended 'cortical immaturity' hypothesis can better account for psychopathic behaviour than the model proposed by Raine.
