Title	The influence of trait psychopathy on the decoding, interference and utilization of emotional information.
Date	2004
Abstract	Research investigating clinical and criminal psychopaths is quite extensive. Though it has evolved in terminology over the years, the basic premise and description of psychopathy has maintained deficits associated with emotional interpretation and experience. The expansion of such research into normal populations has been limited due to the lack of a fuller conceptualization of the disorder. When defining the personality traits associated with psychopathy on a level not requiring criminal or fully antisocial behavior, a broader perspective and therefore understanding of the interaction of these traits in everyone can be conceptualized. Given the paucity of research investigating psychopathic personality traits within the normal population, a directed investigation is necessary for the complete definition and comprehension of psychopathy. Four studies explored the differences in decoding, interference, and utilization of emotional information based on self-report measures of the psychopathic personality style. Study 1 provided evidenced for a reduced threshold of accurate perception among those high on measures of personality psychopathy. Studies 2 and 3 failed to show the expected differences in processing verbal emotional material. Finally, Studies 3 and 4 demonstrated diminished incidental encoding of emotional words and pictures, in those high in trait psychopathy. Together these studies provide preliminary support for significant differences within the normal population in regard to emotional responsivity as it relates to psychopathy, specifically the decoding and utilization of emotional information.
