In his book, Jeffrey Froh writes that an American child who watches three hours of children's television programming a day will see 4,380 good acts in a year but 15,330 acts of violence in that same time. Strong evidence from research indicates that abundant exposure to violent programming and video games is linked to aggressive attitudes, values, and behaviors. In a broad review of more than a hundred studies involving over 130,000 male and female participants from around the world, researchers found that violent video games increase aggressive thoughts, angry feelings, bodily arousal (e.g., heart rate, blood pressure), and aggressive behavior, and that they decrease empathy for others and helping behavior. On the other hand, exposure to prosocial content is linked to good deeds and kindness towards others.
