Brain fitness - reversing old age.

Another item I've noticed a lot of over the past couple weeks is all the websites dedicated to excercising your brain through speeded tasks. Some of these sites are straight up fraud, some are well meaning people who don't quite "get it", while others are run by scientists trying to make a quick buck, ohh I guess there are some run by people who really care and know what they're doing - but I haven't really found one yet. A lot of these sites take tasks that psychologists have been using for years (see nintendo stroop tasks below) to study various cognitive systems and repackaging them as brain stimulators. There is more and more research out there that suggests that these kind of tasks do help elderly folks perform better on.. wait.. more cognitive tasks in the labratory. haha. Ok some of these tasks actually do help "exercise" our brain but I think the most effective brain "exercise" is actual physical exercise. See Art Kramer's research at UIUC.
