Debate: Violent computer games are responsible for aggressive behaviour in teenagers
Side: Not responsible

Firstly, talking about responsibility, there are many reasons for teenage aggression. Violent computer games fall under the topic of media exposure, together with violent movies ,TV shows and music video. So, I humbly disagree that violent video games are responsible for aggressive behaviour in teenagers since there are many other facts that causes aggressive behaviour in teenagersExperimental studies have shown that even a single exposure increases aggression in the immediate situation. For example, Kaj Bjorkqvist randomly assigned one group of five- to six-year-old Finnish children to watch violent movies, another to watch nonviolent ones. Raters who did not know which type of movie the children had seen then observed them playing together in a room. Children who had just watched the violent movie were rated much higher on physical assault and other types of aggression.121 Other experiments have shown that exposure to media violence can increase aggressive thinking, aggressive emotions, and tolerance for aggression, all known risk factors for later aggressive and violent behavior.Psychologists L. Rowell Huesmann, Ph.D., Jessica Moise-Titus, Ph.D., Cheryl-Lynn Podolski, M.A., and Leonard D. Eron, Ph.D., of the University of Michigan undertook the study as a follow-up of a 1977 longitudinal study of 557 children, ages 6 - 10, growing up in the Chicago area. In that study, children identified which violent TV shows they watched most, whether they identified with the aggressive characters and whether they thought the violent situations were realistic.Secondly, other than violent media exposure, there are various other factors.A number of individual characteristics have been shown to increase a child's risk for aggressive behavior. These include a difficult temperament as an infant, low intelligence, hyperactivity, impulsivity, and attention problems. Additionally, aggressive children frequently have poor social problem-solving skills: they often misinterpret other children's behavior as hostile, and they are often unable to find non-aggressive solutions to conflicts.Some characteristics of the home environment can increase the risk that a child will eventually become involved in aggressive behavior. Children and teens who come from homes where parents are coercive or manipulative with their children, provide little emotional support, do not monitor their activities, or have little involvement in their lives are at greater risk for engaging in aggressive behavior. Additionally, the use of harsh punishments or inconsistent discipline has been shown to be related to aggressive behavior in children.Because of their aggressive behavior and lack of social skills, highly aggressive children are often rejected by their peers. This early rejection is predictive of later aggressive and violent behavior. However, by the teen years, most aggressive youth are not friendless, but have developed friendships with other teens with antisocial attitudes and behavior. Friendships with antisocial peers can be an important predictor of aggressive behavior and violence in the teenage years.Early behavior problems often lead to poor school achievement and school failure, which are important risk factors for delinquency and involvement with antisocial peer groups in the teenage years. Neighborhood factors that increase the likelihood that children and teens will become aggressive and involved in other problem behaviors include exposure to violence, the availability of drugs, alcohol and firearms, extreme poverty, neighborhood disintegration ( eg: vacant lots, graffiti, crime, drug dealing, and boarded-up houses), and resident views that are tolerant of misbehavior and violence.Thus I humbly disagree violent computer games are responsible for aggressive teenage behavior since there are so many other factors which are also the causes of such behaviours.
