IntroductionDue to researchers' differing opinions regarding the construct of psychopathy, the distinction between primary and secondary psychopathy, though it has long been recognized to exist, has yet to be fully understood. This distinction, originally proposed by Karpman (1941Karpman ( , 1948, suggests two separate etiologies leading to psychopathy. Whereas primary psychopathy stems from genetic influences resulting in emotional deficits, secondary psychopathy is associated with environmental factors such as abuse (Lee & Salekin, 2010). Additionally, primary psychopathy is characterized by lack of fear/anxiety, secondary psychopathy is thought more to represent a vulnerability to experience higher levels of negative affect in general (Vassileva, Kosson, Abramowitz, & Conrad, 2005).For the reason that primary and secondary psychopathy have been theorized to be related to fearlessness and reckless behavior, respectively, researchers have begun to investigate the relationship between psychopathy and the Reinforcement Sensitivity Theory (RST) of personality (Corr, 2008). Research based on Gray's (1970Gray's ( , 1987 original model of RST has focused on two primary motivational systems: the behavioral inhibition system (BIS) and the behavioral approach system (BAS). In original RST, the BIS is sensitive to cues of punishment and inhibits goal-directed behavior in the presence of such cues. Thus, high BIS activation has been theorized to contribute to processes that, eventually, cause the experience of anxiety. In contrast, the BAS is sensitive to signals of reward, leading to increased goal-directed behavior in the presence of such cues. High BAS activation has been theorized to be related to the trait of reward sensitivity and impulsivity (e.g., Carver & White, 1994). Although Gray (1987) originally posited the BIS and BAS as independently functioning systems (the separable subsystems hypothesis), Corr (2001) In their study, Hughes, Moore, Morris, and Corr (2012) used an undergraduate sample to test the relationships between psychopathy the BAS, BIS, and FFFS. In accordance with Corr (2010), they reported that both primary and secondary psychopathy, as measured by the Levenson's Self-Report Psychopathy (LSRP) Scales (Levenson, Kiehl, & Fitzpatrick, 1995), exhibited a negative association with BIS activation. Primary psychopathy was also shown to be positively related to the BAS -Reward Sensitivity and BAS -Drive facets, and negatively related to BAS Fun-Seeking; and in addition, it was related to FFFS-fear In contrast, in addition to an association with BIS, secondary psychopathy was positively related to Fun-Seeking (impulsivity)In both cases, the BIS can be seen as a cognitive mechanism that detects and resolves goal conflict, and is not simply a measure of anxiety.These results are intriguing but are inconsistent with a number of studies that ...
