The document discusses research on the impact of media violence on youth behavior. Studies have found that exposure to violence in media, like television and video games, can contribute to increased aggressive behavior over time in youth. One study of 820 youth found that violent media use predicted later violence and aggression, especially combined with family or community violence exposure. Researchers recommend media literacy education to help youth critically evaluate media messages and the impacts of violence. Parental control and monitoring of youth media exposure can also help reduce risks.
