Children’s viewing of violent TV shows, their identification with aggressive same-sex TV characters, and their perceptions that TV violence is realistic are all linked to later aggression as young adults, for both males and females. That is the conclusion of a 15-year longitudinal study of 329 youth published in the March issue of Developmental Psychology, a journal of the American Psychological Association (APA). These findings hold true for any child from any family, regardless of the child’s initial aggression levels, their intellectual capabilities, their social status as measured by their parents’ education or occupation, their parents’ aggressiveness, or the mother’s and father’s parenting style.
