So after they studied these brainwaves and whatnot did they bother to see what the long-term outcome of these brain scans indicated? If such readings indicated a fundamental change in the test subjects such that after an hour or two post-game they were still exhibiting the increased aggression, then he might have a case. Otherwise his argument can be applied to anything...like shoveling the driveway in winter increases my aggression. (I absolutely HATE shoveling the driveway.)
In the end his entire experiment is a complete waste of money, proving a fact about a human reaction that exists in a number of ways in one's everyday life.
You raise a completely valid point with studies like this. Most of them are short term studies that look only at the immediate effect. This, honestly, could be a reflection of the Jackie Chan effect (kid walks out of a movie theater after watching a Jackie Chan movie, whats he doing?)
However, this study actually looked at gamers and non-gamers and found that gamers had increased desensitization to violent pictures when compared to non-gamers, suggesting that there is something different between gamers and non gamers to cause the gamers to have that reduced reaction. IF the only differences between gamers and non-gamers is eliminated through randomization, then it stands to reason that games cause gamers to be more desensitized to violent pictures than non-gamers.
Now, while that finding may be
clinically significant, it may not mean much in the real world. That is, a non gamer and I may not mentally have the same neural reaction to violent simuli, but we may physically react to it in the exact same way. For example, maybe a non gamer and I see a dead body in an alley way. I may be less grossed out than the non gamer, but still grossed out enough to want to GTFO, same as them.
