Because aggressive and violent behavior is learned, it can also be unlearned. Further, it is possible to create and maintain conditions in which violence is not learned in the first place. Although psychology has a great deal to offer in addressing the problem of youth violence, the field faces many new challenges in attempting to devise effective solutions.
