- ItemThe causes of rape: Understanding individual differences in the male propensity for sexual aggression(American Psychological Association, 2005-01) Lalumière, Martin L.; Harris, Grant T.; Quinsey, V. L.; Rice, M. E.The Causes of Rape: Understanding Individual Differences in Male Propensity for Sexual Aggression examines why some men are prone to rape, offers probable causes for this inclination, and provides a comprehensive review of scientific studies of coercive sex.
- ItemCoercive and precocious sexuality as a fundamental aspect of psychopathy(Guilford Press, 2007-02) Harris, Grant T.; Rice, M. E.; Hilton, N. Z.; Lalumière, Martin L.; Quinsey, V. L.Sexual behavior is closely associated with delinquency and crime. Although psychopaths, by definition, have many short-term sexual relationships, it has not been shown that sexuality is a core aspect of psychopathy. A Darwinian view of psychopathy led to the hypothesis that psychopaths have a unique sexuality involving early, frequent, and coercive sex. Our subjects were 512 sex offenders assessed on the Hare Psychopathy Checklist (PCL-R). Five variables reflecting early, frequent, and coercive sex loaded on the same principal component in exploratory factor analysis on a subset of the sample, whereas PCL-R items pertaining to adult sexual behavior did not. Confirmatory factor analysis of the remaining subjects yielded a measurement model containing three inter-correlated factors – the traditional two PCL-R factors, and coercive and precocious sexuality. Taxometric analyses gave evidence of a natural discontinuity underlying coercive and precocious sexuality. Coercive and precocious sexuality yielded statistically significant associations with other study variables predicted by the Darwinian hypothesis. The present findings are consistent with prior empirical findings and support the hypothesis that psychopathy has been a nonpathological, reproductively viable, alternate life history strategy.
- ItemNepotistic patterns of violent psychopathy: evidence for adaptation?(Frontiers Research Foundation, 2012) Krupp, Daniel Brian; Sewall, Lindsay A.; Lalumière, Martin L.; Sheriff, Craig; Harris, Grant T.Psychopaths routinely disregard social norms by engaging in selfish, antisocial, often violent behavior. Commonly characterized as mentally disordered, recent evidence suggests that psychopaths are executing a well-functioning, if unscrupulous strategy that historically increased reproductive success at the expense of others. Natural selection ought to have favored strategies that spared close kin from harm, however, because actions affecting the fitness of genetic relatives contribute to an individual’s inclusive fitness. Conversely, there is evidence that mental disorders can disrupt psychological mechanisms designed to protect relatives. Thus, mental disorder and adaptation accounts of psychopathy generate opposing hypotheses: psychopathy should be associated with an increase in the victimization of kin in the former account but not in the latter. Contrary to the mental disorder hypothesis,we showhere in a sample of 289 violent offenders that variation in psychopathy predicts a decrease in the genetic relatedness of victims to offenders; that is, psychopathy predicts an increased likelihood of harming non-relatives. Because nepotistic inhibition in violence may be caused by dispersal or kin discrimination, we examined the effects of psychopathy on (1) the dispersal of offenders and their kin and (2) sexual assault frequency (as a window on kin discrimination). Although psychopathy was negatively associated with coresidence with kin and positively associated with the commission of sexual assault, it remained negatively associated with the genetic relatedness of victims to offenders after removing cases of offenders who had coresided with kin and cases of sexual assault from the analyses.These results stand in contrast to models positing psychopathy as a pathology, and provide support for the hypothesis that psychopathy reflects an evolutionary strategy largely favoring the exploitation of non-relatives.
