In the article here: http://www.msnbc.msn.com/id/16099971/ns/technology_and_science-games/t/does-game-violence-make-teens-aggressive/#.TrdoaXZQqtQ it discusses a recent study done at Kansas State University that finds violent video games to cause less control in adolescents. The article claims that after doing an MRI 30 minutes after a teen was playing "Medal of Honor" (A vicious killing game) that showed a decrease in activity in the brain where the self control and attention part of the brain functions, the cerebrum. The psychology textbook discusses this topic as well and suggests that there are studies that prove both that video games do cause some kids to be more violent but there are some studies that prove it does not play a factor. I lean towards the side believing that violent video games do in fact play a role in a child's behavior. During the ages up until adolescents Piaget theorized that our cognitive development does not think abstractly. Therefore, if kids cannot think beyond the facts of what is violently happening in the video game, who says they won't be stuck in a mind set, and develop thoughts that are like what they are doing. I do not believe that adults 18+ are affected by violent video games because they are not developing still in the cognitive stage, whereas adolescents and younger are. Violent games bring out a defensive, lack of control emotion to the player. The players don't necessarily do the exact same thing as what they are doing in the game, but I myself after playing a shooting game have felt an aggressive superior emotion (Also like what we found after watching aggressive shows in psych discussion class). From the credible article with a replicable study, it provides evidence that in fact violent video games can play a role in behavior of young adults.
