The relationships among psychopathy, empathy, and aggression

Abstract

IntroductionThe lack of empathy is often described as one of the core characteristics of psychopaths. However, prior studies on cognitive empathy in psychopaths have led to mixed conclusions, with some indicating that psychopaths have no impairments in cognitive empathy.ObjectivesThis study set out to resolve this inconsistency by distinguishing the two factors that constitute the construct of psychopathy: Factor 1 (e.g., emotional callousness, lack of guilt) and Factor 2 (e.g., irresponsible lifestyle, poor behavioral controls).AimsThe main aim of this study was to examine the differential relationship between these two factors and relevant variables including empathy, aggression, satisfaction with life.MethodsSelf-report questionnaires and two online experiments (facial affect recognition task, emotional scenario task) were administered to 306 undergraduate students to collect data about psychopathy, cognitive/affective empathy, aggression, satisfaction with life.ResultsCorrelation analysis revealed that both Factor 1 and Factor 2 had negative correlations with self-reported measures of cognitive/affective empathy, and only Factor 1 emerged as a significant predictor of both kinds of empathy. Aggression also showed a stronger positive correlation with Factor 1 than with Factor 2, regardless of subtypes (instrumental, reactive, relational, overt aggression). On the other hand, satisfaction with life was more negatively correlated with Factor 2 than Factor 1, and regression analysis revealed that only Factor 2 was a significant predictor.ConclusionsThis study showed Factor 1 is more important than Factor 2 in explaining both empathy and aggression in psychopath, while satisfaction with life is better explained by Factor 2 than by Factor 1.Disclosure of interestThe authors have not supplied their declaration of competing interest.
