title: [Cognition-Emotion Interactions and Psychopathic Personality: Distinct Pathways to Antisocial and Violent Behavior].
abstract: Researchers have long acknowledged heterogeneity among persons who exhibit antisocial and violent behaviours. The study of psychopathic personality or psychopathy can help elucidate this heterogeneity through examination of the different facets that constitute this disorder. In particular, the distinct correlates of the interpersonal-affective traits (Factor 1) and the impulsive-antisocial traits (Factor 2) of psychopathy suggest at least two possible pathways to antisocial behaviours. Building on basic studies in cognitive and affective neuroscience, we provide a focused, non-comprehensive review of work identifying the biopsychological mechanisms involved in these two pathways, with special attention to studies using event-related potential (ERP) methods. In specific, a series of studies are discussed which examined affective and cognitive processes that may distinguish offenders high on psychopathic traits from other offenders, with emphasis on alterations in emotion-cognition interactions related to each factor of psychopathy. The set of findings reviewed highlight a central conclusion: Factor 1 represents a pathway involving reduced emotional responding, exacerbated by attentional abnormalities, that make for a more deliberate and emotionally insensitive offender profile. In contrast, Factor 2 characterizes a pathway marked by emotional and behavioural dysregulation and cognitive control dysfunctions, particularly in emotional contexts. Implications for identifying etiological processes and the further understanding of antisocial and violent behaviours are discussed.
