It is obvious in this book that violence has changed the way people act. In America violence is not to this extent, but is still very prevalent. In our culture violence is everywhere, especially in the media and entertainment. One of the biggest effects on children is growing up playing video games, most of which have extremely violent content. A study done by Journal of Adolescence shows that the effects of these games are severe. Their study showed that "adolescents who expose themselves to greateramounts of video game violence were more hostile, reported getting into arguments with teachers more frequently, were more likely to be involved in physical fights, and performed more poorly in school." With the average kid playing video games for more than seven hours a week, and 89% of all video games containing violent content this is a serious problem. Out of the many studies done on this subject a large percent of them found a strong connection between playing violent video games and a higher amount of aggressive behavior and aggressive emotions. The effects of violent video games has been said to lead kids to act out violently. These games glorify violence from war to gangs, and make it seem like something kids would want to be a part of; this is why parents need to monitor the amount of violent games their kids are playing.
