title: "Do unto others"? Distinct psychopathy facets predict reduced perception and tolerance of pain.
abstract: Recent research has sought to understand how individuals high in psychopathic traits perceive pain in others (Decety, Skelly, & Kiehl, 2013; Marsh et al., 2013). Perception of pain in others is presumed to act as a prosocial signal, and underreactivity to others' pain may contribute to engagement in exploitative-aggressive behaviors among individuals high in psychopathic traits (Jackson, Meltzoff, & Decety, 2005). The current study tested for associations between facets of psychopathy as defined by the triarchic model (Patrick, Fowles, & Krueger, 2009) and decreased sensitivity to pain in 105 undergraduates tested in a laboratory pain assessment. A pressure algometer was used to index pain tolerance, and participants also rated their perceptions of and reactivity to the algometer-induced pain during the assessment and again 3 days later. A unique positive relationship was found between pain tolerance and the meanness facet of psychopathy, which also predicted reduced fear of painful algometer stimulation. Other psychopathy facets (boldness, disinhibition) showed negative relations with fear of pain stimulation during testing and at follow-up. Findings from this study extend the nomological network surrounding callousness (meanness) and suggest that increased pain tolerance may be a mechanism contributing to insensitivity to expressions of discomfort in others.
