Differentiating psychopathy from general antisociality using the P3 as a psychophysiological correlate of attentional allocation.

Recent studies have shown that while psychopathy and non-psychopathic antisociality overlap, they differ in the extent to which cognitive impairments are present. Specifically, psychopathy has been related to abnormal allocation of attention, a function that is traditionally believed to be indexed b...
