This article tells that video games do not have any correlation with violence. The article also goes on to say that all graphic material, including television, doesn’t link to violence. I on the other hand think that playing violent video games is almost an emotional catharsis for teens and young adults. When aggravated or angry, why not take it out on a virtual player in a gun battle. Well, it is proven that erupting emotions in violent acts is detrimental to anyone. If people are using violent video games as method of releasing built up tension, or emotions, they are doing a disservice to their own well being. Catharsis usually alleviates the stress temporarily, but the emotions return, without solving anything.

Functional MRIs are used in this study mentioned in the article to compare brain activity. The data collected showed that adolescents playing violent video games had changes in brain activity than the adolescents that played non-violent games. This article backs some views that violent video games can change behavior. Although, the research didn't show if the effect of playing was permanent or not. Also, the research did not show if the changes in the brain activity created more violence. I still believe that the change in mental operation is bad for a person. This change could be due to the emotional expulsion through the video game. The article says the only differece between the games played is violent, or non-violent. But, I feel that there could be more differences to the games that could casue this change in chemicals in the brain.
