FOlks,

I ame in late on this one, but perhaps this will help.



       Anderson, Craig A; Bushman, Brad J  (2001). Effects of violent 
video games on aggressive behavior, aggressive cognition, aggressive 
affect, physiological arousal, and prosocial behavior: A 
meta-analytic review of the scientific literature. Psychological 
Science. 12(5), 353-359.

This is a meta-analysis that show clear effects in agressive 
cognition, aggressive affect, general arousal, and reductions in 
prosocial behavior.

It refers to the problems of demonstrating causility in this and related areas.
