Lewis, your post reminded me of an interesting TED talk on video games given by cognitive researcher Daphne Bavelier:
Daphne Bavelier: Your brain on video games | Video on TED.com
I realize this is anecdotal evidence but my husband teaches High School and he's found that the kids that play video games are often the more intelligent. I may be a little biased because our son is unschooled and plays a lot of video games, whenever he meets new people they always remark on how intelligent and mature he is. Maybe he's just the exception.
I honestly credit video games with my terrible homework scores and awesome test scores all throughout school.

PS, my reflexes are insanely good.
Much better than this guy's...
