Affective empathy differs in male violent offenders with high- and low-trait psychopathy

This study investigated affective and cognitive empathic processes in incarcerated violent offenders with lower and higher psychopathic traits and healthy controls. Participants witnessed painful expressions of others displayed on video clips. Skin conductance responses (SCR) were recorded to assess autonomic emotional arousal, and various empathy ratings were used as measures of self-reported vicarious responses. Reduced SCRs occurred during the observation of pain in others in lower and higher psychopathic-trait participants alike, compared to controls. Despite these diminished autonomic responses indicating reduced vicarious responses, only inmates with higher psychopathic traits provided empathy ratings comparable to those of the controls. These findings indicate that violent offenders display reduced autonomic arousal in response to distress cues of others, irrespective of psychopathy. However, only higher psychopathic-trait offenders were able to provide self-report in a way that let them appear to be as empathic as controls-enabling them to know, yet not to feel, what others feel.
