Violent Video Game Effects on Children and Adolescents

Abstract

Violent video games are increasingly popular, raising concerns by parents, researchers, policy makers, and informed citizens about potential harmful effects. Chapter 1 describes the history of violent games and their explosive growth. Chapter 2 discusses research methodologies, how one establishes causality in science, and prior research on violent television, film, and video games. Chapter 3 presents the General Aggression Model, focusing on how media violence increases aggression and violence in both short and long-term contexts. Important scientific questions are answered by three new studies. Chapter 4 reports findings from a laboratory experiment: even children's games with cartoonish violence increased aggression in children and college students. Chapter 5 reports findings from a survey study of high school students: frequent violent game play leads to an angry and hostile personality and to frequent aggression and violence. Chapter 6 reports findings from the first longitudinal study video game effects: elementary school children who frequently played violent games early in the school year became more verbally and physically aggressive, and less helpful. Chapters 7 and 8 compare a host of risk factors for development of aggression, and find video game effects to be quite important. Chapter 9 describes the role of scientific findings in public policy, industry responses to scientific findings, and public policy options. Chapter 10 recommends that public policy debates acknowledge the harmful effects of violent video games on youth, and urges a more productive debate about whether and how modern societies should act.
