Debate: Violent computer games are responsible for aggressive behaviour in teenagers
Side: Responsible

Yes, I agree that violent video games are responsible for aggressive behaviours in children and teenagers. Violent video games cause behavior problems, because constant exposure to violence desensitizes the player. This exposure to violence also acclimates the player to performing violent acts in real life. When children and teenagers, participate in violent video games, they become immune to the true impact of violent behaviour. As violence in video games has no negative consequences and offers "winning" as a reward, they lose the ability to empathize with the victim and are encouraged to think that violence causes no harm to others. Then, it is very easy to transfer this video/game violence to real violence. According to a research done by scientist in the year 2011, playing violent video games does cause players to become more aggressive. The findings of a new University of Missouri (MU) study provide one explanation for why this occurs: the brains of violent video game players become less responsive to violence, and this diminished brain response predicts an increase in aggression."Many researchers have believed that becoming desensitized to violence leads to increased human aggression. Until our study, however, this causal association had never been demonstrated experimentally," said Bruce Bartholow, associate professor of psychology in the MU College of Arts and Science.During the study, 70 young adult participants were randomly assigned to play either a non-violent or a violent video game for 25 minutes. Immediately afterwards, the researchers measured brain responses as participants viewed a series of neutral photos, such as a man on a bike, and violent photos, such as a man holding a gun in another man's mouth. Finally, participants competed against an opponent in a task that allowed them to give their opponent a controllable blast of loud noise. The level of noise blast the participants set for their opponent was the measure of aggression.The researchers found that participants who played one of several popular violent games, such as "Call of Duty," "Hitman," "Killzone" and "Grand Theft Auto," set louder noise blasts for their opponents during the competitive task (this shows that they were more aggressive) than participants who played a nonviolent game. In addition, for participants that had not played many violent video games before completing the study, playing a violent game in the lab caused a reduced brain response to the photos of violence (which is an indicator of desensitization). Moreover, this reduced brain response predicted participants' aggression levels: the smaller the brain response to violent photos, the more aggressive participants were. Participants who had already spent a lot of time playing violent video games before the study showed small brain response to the violent photos, regardless of which type of game they played in the lab.This study shows that violent games does affect children and teenagers’ mentality and it increases the chance of them to have aggressive behaviours. Thus, violent video games desensitize the players to actual violent acts.
