Description
Summary:BackgroundThere is relatively little existing information regarding the neuralcorrelates of deception in individuals with psychopathic traits.AimsTo investigate the relationship between neural responses during deceptionand psychopathic personality traits in a sample of male participantsdrawn from the normal population.MethodTwenty-four male participants carried out a simple deception paradigmwhile undergoing functional magnetic resonance imaging. Psychopathictraits were assessed in the sample using the Psychopathic PersonalityInventory (PPI).ResultsMean response times were greater for the lie than truth condition. Lieresponses resulted in enhanced activation of the ventrolateral prefrontalcortex. The PPI sub-scales, coldheartedness, fearlessness, Machiavellianegocentricity, social potency and stress immunity were found to becorrelated with activation patterns in the brain circuitry implicated inboth deception and related processes such as behavioural restraint andsocial cognition.ConclusionsThis is a novel technology that may prove useful in our understanding ofsome of the key components of the psychopathy construct in both clinicaland non-clinical contexts.
