3. Résumé

«[E]xposure to media violence was related to subsequent antisocial behavior. Any amount of exposure to screen time perceived by parents as violent was associated with small increases in teacher-rated antisocial behavior several years later. Specifically, children who viewed violent media were at a slight, but detectable increased risk of demonstrating cold and uncaring behavior in second grade classroom situations involving peer relationships. Our most novel findings are that children exposed to any amount of violent programming showed modest, yet significant increases in negative affect symptoms. These include not seeming as cheerful as other children and appearing more sad or unhappy than their second-grade classmates.» (p. 295) Les auteures concluent en affirmant que «these observed effects seem robust as they remained significant above and beyond a number of child and family characteristics, including maternal involvement and hostile parenting, parental antisocial symptoms, and family functioning and configuration. In addition, because we examine prospective longitudinal associations, it is likely that the observed effects are cumulative throughout the life course and thus more important than suggested by the present measures.» (p. 295)
