A superficially charming and engaging personality combined with a ruthless willingness to "do whatever it takes to get the job done" can be extremely useful in a high-stakes, pressure-filled environment (Schouten and Silver, 2012, p. — Antisocial personality disorder (APD) is not synonymous with psychopathy: most psychopaths will also be given an APD diagnosis, however, many who are diagnosed as APD are not considered psychopaths (a unique group receiving little research attention). — APD has a lifetime (community) prevalence of 2 - 4% in the United States, but this varies widely with gender, men being about 6.5 % women being about 1%. Psychopaths do not have the fear response experienced by most of us to the potential negative consequences of criminal or risky behavior and are relatively insensitive to punishment. Using factor analysis, item response theory, and multidimensional scaling, we propose that the PCL-R and its derivatives are underpinned by at least four correlated factors: Interpersonal, Affective, Lifestyle, and Antisocial. Given that the modeling results to date indicate a moderate to strong covariation of four dimensions of psychopathy (Interpersonal, Affective, Behavioral, and Antisocial), it would be prudent to assume that the longitudinal relations among these dimensions are interactive and reciprocal, and that the "real" core of psychopathy has yet to be uncovered. We also argue that the idea of construct "drift" is irrelevant to current conceptualizations of psychopathy, which are better informed by the extensive empirical research on the integration of structural, genetic, developmental, personality, and neurobiological research findings than by rigid adherence to early clinical formulations. They tend not to be deterred from their self-serving behaviors by criminal or social penalties. We argue that attempts to characterize antisocial behaviors as merely "downstream" manifestations of more central traits are inconsistent with the structural properties of the PCL-R and with evidence that the development of traits and actions are interactive and reciprocal. We offer some suggestions for future research on psychopathy. Either their transgressions of social norms, while destructive and painful to those involved, do not rise to the level of criminal activity, or they are never apprehended by the police for the crimes they do commit. While true psychopaths share certain behavioral and emotional attributes, they are not all identical, and they exhibit these various characteristics to a greater or lesser degree. Cleckley's emphasis of the psychopath as a constellation of various personality traits was essentially overturned by the American psychiatric establishment in revisions to the DSM, culminating in 1980 in a behaviorally based description and the use of the term antisocial personality disorder. Males showed a stronger modulatory relationship between inferior parietal activity and moral ratings relative to females. Consistent with hypotheses, an analysis of brain activity during the evaluation of pictures depicting moral violations in psychopaths versus nonpsychopaths showed atypical activity in several regions involved in moral decision-making. doi:10.1016/0162-3095(87)90019-7 Sociopathy in males and hysteria (Briquet's syndrome) in females very closely fit predictions from a model of characteristics of cheaters or nonreciprocators in a complex social system. Two correlated factors have been identified in the Psychopathy Checklist (PCL), a valid and reliable instrument for the assessment of psychopathy in male prison populations. Robert Hare, through his writing and widely popular testing initiatives, returned to a personality/trait approach derived from Cleckley's original factors. The cambridge handbook of personality psychology (pp. These results are suggestive of gender differences in strategies utilized in moral appraisals. This included reduced moral/nonmoral picture distinctions in the ventromedial prefrontal cortex and anterior temporal cortex in psychopaths relative to nonpsychopaths. Such a model is discussed and characteristics of sociopaths and hysterics are described. Factor 1 measures a selfish, remorseless, and exploitative use of others, and Factor 2 measures a chronically unstable and antisocial life-style.
The modern era of thinking about psychopathy begins with Cleckley's work, originally done in 1941. As predicted, females showed a stronger modulatory relationship between posterior cingulate and insula activity during picture viewing and subsequent moral ratings relative to males. To address this issue, the authors used functional magnetic resonance imaging (f MRI) to record hemodynamic activity in 72 incarcerated male adults, stratified into psychopathic (n = 16) and nonpsychopathic (n = 16) groups based on scores from the Hare Psychopathy Checklist-Revised (R. Hare, 2003), while they made decisions regarding the severity of moral violations of pictures that did or did not depict moral situations. Psychological Assessment: Journal of Consulting and Clinical Psychology, 1(1), 6-17. Instrumental aggression (sometimes called proactive or predatory aggression) is planned, controlled, and purposeful, and is used for a particular aim—for example, to get drugs or sex, or just to establish dominance. Failure to accept responsibility for own actions 17. The primary goal is not necessarily to injure others but simply to obtain the desired outcome. Hare's approach and tests have been particularly influential both in practical forensic settings and in academic research. In a separate analysis, the association between severity of moral violation ratings and brain activity across participants was compared in psychopaths versus nonpsychopaths. Since a successful cheating adaptation should require, above all else, concealment of the trait, recognition and diagnosis of these traits in humans will always be difficult and ambiguous at the level of language and interpersonal interaction. We examined the psychometric properties of the factor solutions and a variety of correlates of the two factors. Although a number of other tests of psychopathy have been developed and a number of authors have expressed reservations about Hare, Hare's approach has dominated. Results revealed a positive association between amygdala activity and severity ratings that was greater in nonpsychopaths than psychopaths, and a negative association between posterior temporal activity and severity ratings that was greater in psychopaths than nonpsychopaths. Although the PCL can be considered a homogeneous scale on statistical grounds, the factors have distinct patterns of intercorrelations with other variables.
