Neural Processing of Social Exclusion in Individuals with Psychopathic Traits: Links to Anger and Aggression

Aggression is hostile, unfriendly behavior that often results in physical, social, and/or emotional harm. Aggressive acts entail not only tangible costs (e.g., financial; Corso et al., 2007; Waters et al., 2005), but also intangible costs (e.g., psychological; McCollister et al., 2010). A host of factors (e.g., personality traits, environmental conditions, neural dysfunction, genetics) are known to influence risk for engaging in aggression. One factor reliably linked to higher rates and severity of aggression is psychopathy (Hare& McPherson, 1984; Kruh et al., 2005; Murrie et al., 2004; Salekin et al., 1996; Serin& Amos, 1995), a disorder characterized by a set of traits including callousness, manipulativeness, and impulsivity.
