Neuropsychological correlates of self-reported impulsive aggression in a college sample

The present study examined the neuropsychological correlates of impulsive aggression/violence using a population which is considered to be functioning ‘normally’ by societal standards, college students. Subjects were 12 college students classified as impulsive aggressive by self-report and 12 nonaggressive matched controls. All impulsive aggressive subjects reported a lifetime history of physical aggressive outbursts. The neuropsychological findings suggest that impulsive aggressives share a pathological focus involving specific executive control processes: impulse control and verbal strategic processing. These findings are consistent with the neuropsychological and psychophysiological findings in impulsive aggressive incarcerated criminals and support the notion of a specific behavioral syndrome associated with spontaneous aggressive outbursts.
