Book excerpt: The Crisis of School Violence is the only interdisciplinary book about school violence. It presents a broad and in-depth approach to the key questions about why bullying continues at an unprecedentedly high rate and why rampage school shootings continue to shock the nation. Based on extensive research, The Crisis of School Violence investigates human nature and its relation to aggressive behavior, with a special focus on the culture of violence that predicates school violence (including rampage shootings) and perpetuates industries that profit from violence. Marianna King presents the considerable psychological and neuroscientific research that investigates the effects of violent entertainment media on the brain and, subsequently, on behavior, which clearly reveals a causal connection between exposure to violent electronic entertainment media--especially violent video games--and increased aggressive and violent behavior. The book also reveals a more specific connection between exposure to violent video games and rampage school shootings. Ultimately this volume is a call to action that includes recommendations for parents, teachers, decision makers, and citizens alike.
