Psychopathic individuals display characteristic deficits in processing emotion cues, the abstract meaning of words, and peripheral inhibitory cues, that have been linked to deficits in self-regulation and antisocial behavior. One view, supported by recent research, is that psychopathic individuals have difficulty processing set-incongruent information and that their difficulty may be ameliorated using task manipulations that establish a set-relevant focus of attention. We evaluated this characterization of the psychopathic deficit using a lexical decision (i.e., word recognition) task and priming manipulation that caused target stimuli to be set-congruent or set-incongruent. As predicted, low-anxious (i.e., primary) psychopathic participants displayed a significantly greater priming effect than low anxious non-psychopathic participants. The results highlight the potential value of priming relevant cognitive sets to overcome the costly information processing deficits associated with psychopathy. Treatment efforts emphasizing a balance of attention between primary and peripheral information may prove especially effective for reducing maladaptive behavior in psychopathic individuals.
