Anger following provocation in individuals with psychopathic traits

摘要

Purpose - The purpose of this paper is to test the attenuated-anger and heightened-anger hypotheses of psychopathy by assessing the physiological, behavioral, and subjective measures of anger in individuals with and without psychopathic traits. Design/methodology/approach - In all, 62 male college students were assigned to one of three groups based on evidence of elevated affective-interpersonal (Factor 1) and antisocial lifestyle (Factor 2) traits associated with psychopathy (the IF1+F2 group), evidence of only Factor 2 traits (the F2 only group), or based on the absence of psychopathic traits (the control group), using Gough's (1957) Socialization scale and a modified, interview only form of Hare's (1991) Psychopathy Checklist-Revised. To induce anger, participants received unjust criticism about their performance on a computer-based affective lexical decision task and were denied a performance bonus they had reason to expect. Findings - Following provocation, the three groups displayed similar increases in blood pressure, pulse, and self-reported anger. The control and IF1+F2 groups also displayed similar retaliation toward the confederate. However, the IF1+F2 group displayed smaller increases on two of three measures of facial muscle activity associated with anger. Originality/value - This study is one of the first to assess anger responsiveness in individuals with psychopathic traits using a powerful anger induction and using physiological, behavioral, and subjective indices of anger. It is also the first to assess both the attenuated-anger and the heightened-anger hypotheses of psychopathy. The findings appear largely inconsistent with both perspectives.
