Gray’s model and psychopathy: BIS but not BAS differentiates primary from secondary psychopathy in noninstitutionalized young adults

Gray’s two-factor model represents motivation in terms of a behavioral inhibition (BIS) and a behavioral activation system (BAS). Although this model has theoretical links to psychopathy, few studies have examined this relationship. In a sample of 326 noninstitutionalized young adults, we examined the relationship of the BIS/BAS dimensions to multiple indices of primary and secondary psychopathy. Across measures of psychopathy, primary but not secondary was related to BIS standing, whereas indices of both psychopathic dimensions demonstrated robust, positive relationships to the BAS. Generally, results support Newman, MacCoon, Vaughn, and Sadeh (2005) distinction between primary and secondary psychopathy on the basis of the BIS. However, positive associations of all psychopathy measures with BAS indices emphasize the role of a common BAS in psychopathy. 2007 Elsevier Ltd. All rights reserved.
