Psychopathy and verbal emotion processing in non-incarcerated males

Incarcerated males who score high on personality measures of psychopathy are reported to be less efficient than other incarcerated males in processing emotionally laden stimuli. In this study, we evaluated whether an emotion deficit is also present in non-incarcerated higher functioning males who score high on psychopathy personality measures. A sample of male university students was screened for psychopathic personality, and two subsamples, those who scored high or low on global psychopathy, participated in a series of language processing tasks designed to assess verbal emotion processing. Unlike previous studies of emotion processing in the verbal domain, stimuli also systematically varied in abstractness. The results showed that participants scoring high in psychopathy were less efficient than those scoring low in psychopathy in processing negatively valenced words, across all levels of word abstractness. The results extend previous accounts of emotional processing deficits in individuals with psychopathic personality to a relatively high-functioning non-incarcerated sample.
