Hi Don. For a good study that (in my opinion) satisfies your requirement for a high-action no-violence group, take a look at Carnagey and Anderson (2005). Ps played either a violent version of Carmageddon 2, a version where violence was punished (points were lost for killing people/hitting objects, and a no-violence version (same game) where violence wasn't possible. Aggressive affect, cognition, and behavior all differed in the reward compared to the no-violence group, and aggressive cognition and behavior differed between the reward and the punishment groups.
Also, what about the meta-analysis done by Anderson and Bushman (2001), which found no gender diffs and no diffs as a function of experimental vs. correlation studies? Granted, the rs were all in the range of .16-.27, but as the authors note, the average effect size was the same as that between condom use and the prevention of HIV. Do we take that association seriously? -- Mark At 02:06 PM 3/27/2008, you wrote: >It's this kind of junk science that really gets my goat.
