Verbal intelligence and self-regulatory competencies: Joint predictors of boys¬タル aggression ¬リニ

Two studies examined the interactive eVect of receptive verbal intelligence measured by the Peabody Picture Vocabulary Test and self-regulatory competencies measured in the delay of gratiWcation paradigm on boys’ aggression. Study 1 participants (ND 98) were middle school, low-income boys primarily ethnic minority. Participants for Study 2 (ND 59) were drawn from a treatment camp for boys from low-income neighborhoods with behavioral adjustment problems. In both studies, the interaction between verbal intelligence and self-regulation was signiWcant such that verbal intelligence was associated with lower aggression to a greater extent among boys who had eVective self-regulatory skills than among those who had ineVective self-regulatory skills. The implications of these Wndings for interventions and for a theory of risk factors in aggression are discussed. © 2006 Elsevier Inc. All rights reserved.
