Clarifying relations between dispositional aggression and brain potential response: Overlapping and distinct contributions of impulsivity and stress reactivity

► Dispositional aggression inversely related to target and novel P3 ERP amplitude. ► Aggression deficits strongest over anterior scalp recording sites. ► Aggression accounted for inverse relationship between P3 and impulsivity. ► Stress reactivity positively related to target P3 when controlling for aggression.
