I think you're right, but I think you're coming at this defense from the wrong angle.
He is demonstrating that exposure to violence in video games can desensitize a person to the idea of violence. Not only does he appear to demonstrate this in the brain, it also makes sense--the more you see
anything, the less shocking/surprising/novel it will be.
He then claims that subjects behaved "more aggressively" when asked to "blast an opponent" with a loud noise. And that this means the desensitization is encourage, or even
prompting, this aggressive behavior. Don't we think, perhaps, the fact that you
told them to do it is what led to this behavior?
So, it seems that the desensitization elevated their willingness to engage, but it didn't
cause aggressive behavior. You could say it elevated it
when already present or cued.
Furthermore, could that also just be because subjects engaged in a
competitive game are encouraged to be more "aggressive" in order to win? See, "aggression" and "violence" are not the same thing. Violent videogames, however, pit human against human(oid) in
competition, which may stimulate our basic hypothalamus "fight or flight" response in a mild way. That could make us more likely to react more strongly in perceived competition.
In order for this study to hold any real water, we'll need to know:
1. What were the "non-violent" games being played?
2. Were any of these games
competitive non-violent games?
3. If not, what effect do
competitive non-violent games have on the "sound blasting" choices?
4. If some of them were, was there any "statistically significant" difference between those and the
non-competitive non-violent games?
5 Do other competitive endeavors outside of video games have any similar impact? (Sports, martial arts, really
any competitive activity)
We have to be extremely careful how we define things like "aggressive" and "violent," and be careful not to conflate them with traits like being "competitive" or just "in an excited state."
