Although impulsivity has been repeatedly associated with aggression, specific associations between facets of impulsivity and reactive (RA) and proactive (PA) have yet to be fully elucidated. This may be due, in part, to overlapping variance among facets of impulsivity and between RA/PA. The current study systematically examined associations among these(More)
The current work sought to operationalize constructs of the triarchic model of psychopathy in chimpanzees (Pan troglodytes), a species well-suited for investigations of basic biobehavioral dispositions relevant to psychopathology. Across three studies, we generated validity evidence for scale measures of the triarchic model constructs in a large sample(More)
BACKGROUND The construct of psychopathy is sparsely researched in the non-Western world, particularly in the Middle East. As such, the extent to which the psychopathy construct can be generalized to other cultures, including Middle Eastern Arab cultures, is largely unknown. METHODS The present study investigated the cross-cultural/national comparability(More)
Callous and Unemotional (C&U) traits characterize a group of adolescents who engage and persist in especially severe antisocial behaviors. These traits have been included in DSM-5 within a "Limited Prosocial Emotions" (LPE) specifier for Conduct Disorder. To investigate the generalizability of this specifier to non-Western cultures, we examined associations(More)
Coldheartedness is a subscale of the Psychopathic Personality Inventory-Revised (PPI-R) that does not load onto either of the PPI-R's two traditional higher order factors (Fearless Dominance [FD] and Self-Centered Impulsivity [SCI]). As a result, it has been omitted from analyses in many studies. However, owing to Coldheartedness's associations with lack of(More)
Psychopathy is a multidimensional construct that is broadly associated with both reactive (RA) and proactive (PA) aggression. Nevertheless, a consistent pattern of associations between psychopathy and these 2 aggression subtypes has yet to emerge because of methodological differences across studies. Moreover, research has yet to examine gender differences(More)
Converging empirical data suggests that a set of largely consistent personality traits exist in both human and nonhuman primates; despite these similarities, almost nothing is known concerning the neurobiological basis of these traits in nonhuman primates. The current study examined associations between chimpanzee personality traits and the grey matter(More)
The current study explored the nuanced associations between components of executive functioning (EF) and subtypes of aggression, using a latent variable approach. Participants were racially diverse undergraduate students who completed a self-report of reactive (RA) and proactive aggression (PA), and traditional neuropsychological tasks of EF. The(More)
