is essential for understanding how media violence affects youth behavior and for framing any coherent public health response to it. Although this report focuses generally on the violent behavior of adolescents, it is critical to understand how children are influenced by and respond to media violence, especially in order to recognize and help those who are particularly susceptible to adverse effects. Most youths who are aggressive and engage in some forms of antisocial behavior do not become
violent teens and adults. However, it is well established that many violent adolescents and adults were highly aggressive and even violent at younger ages, and the highly aggressive child is at increased risk of growing up to be a more aggressive young adult (Nagin & Tremblay, 1999).Because influences that promote aggressive behavior in some young
children can contribute to increasingly aggressive and even violent behavior many years later, it is important to understand the early factors that may play a role in later outcomes.
