Note: This one almost belongs in the "Well Duh" file except for the fact that the agressive behavior shows up on a functional MRI. I so often see parents walking around with their children talking away while the poor kid has his nose buried in a portable video game and is totally oblivious to the world around him (almost always boys). I have to wonder at the direct relationship between video games and the training of soldiers in high-tech war equipement. Are are children being trained from a very young age to be mindless killers? Maybe this one belongs in the "Well Duh" file as well.
In a functional magnetic resonance imaging (fMRI) study, 13 male research participants were observed playing a latest-generation violent video game. Each participant's game play was recorded and content analyzed on a frame-by-frame basis.
There is a causal link between playing the first-person shooting game in our experiment and brain-activity pattern that are considered as characteristic for aggressive cognitions and affects, said Ren-Weber, assistant professor of communication and telecommunication at MSU and a researcher on the project. There is a neurological link and there is a short-term causal relationship.
Violent Video Games Lead To Brain Activity Characteristic Of Aggression
