The accuracy of perception of facial emotion expressions was studied in individuals with low and high psychopathic personality characteristics in a sample of 21 male and 39 female university students. Participants completed the Psychopathic Personality Inventory (PPI), and the Behavioural Inhibition Scale and the Behavioural Activation Scale (BIS/BAS) as measures of psychopathy. Participants completed a computerised emotion recognition task containing six emotions of facial expressions (each emotion had five different intensities). The results showed that participants scoring low on the BIS and high on the BAS scores showed significant impairments in the recognition of both sad and fearful expressions. On the other hand, group scoring high on the PPI, showed significant impairment in the recognition of angry, but not fearful or sad expressions in the total sample. Males with high psychopathic personality characteristics showed significant impairments in the recognition of sad, fearful and angry expressions compared to males with low psychopathic personality characteristics. On the other hand females with high psychopathic personality characteristics showed significant impairment in recognising the expression of disgust only compared to females with low psychopathic personality characteristics. The PPI and the BIS/BAS scales showed reasonable alpha reliabilities with some exceptions for one subscale in each measure. Correlations between the PPI and the BIS/BAS scales were weak to moderate. The current findings suggest that different dimensions of psychopathy may be associated with selective impairments in recognising unpleasant emotion expressions in others.
