Title: Adolescent impulsivity and novelty seeking as differential predictors of relational and overt aggression
Legend: Mother- and self-reported impulsivity during adolescence predict concurrent overt aggression reported by cotwins. This pattern remained the same when predicting relational aggression. Although impulsivity predicted both types of aggression, mother- and self-reported novelty seeking did not predict aggression of either type, suggesting that impulsivity and novelty seeking are conceptually distinct.

Abstract: Impulsivity is commonly conflated with novelty seeking, but these traits are conceptually independent and hold different predictive implications. Using a multi-informant design, we examined adolescent impulsivity and novelty seeking as predictors of aggression in a sample of 976 twins. Higher impulsivity predicted both overt and relational aggression, controlling for sex, puberty status, age, and socioeconomic status. Novelty seeking did not predict aggression, a finding that supports its independence from impulsivity.
