Abstract

Event-related potentials (ERPs) were used to examine the processing of facial affect in relation to psychopathy. Participants (N = 27) completed the Psychopathic Personality Inventory (Lilienfield, 2005) and were divided into the two experimental groups (high PPI and low PPI). The electroencephalogram (EEG) was recorded while participants viewed and responded to faces at three categories of emotional valence (happiness, fear, and anger). Two ERP components, previously identified as being elicited during facial recognition tasks, were of interest: the N170 and the N250. There were no significant group differences for the N170 component. There was a group difference in ERP amplitude in response to the faces when ERP responses were collapsed across emotional facial expressions and electrode sites suggesting that individuals with higher levels of psychopathy process emotional faces differently than those with lower levels of psychopathy.
