[citation][nom]pythy[/nom]Why did the study only consist of adolescent girls? Would tetris have a negative effect on adolescent boys i wonder?[/citation]
nah, the virgin nerd scientists prolly wanted to examine chicks only
[citation][nom]KyleSTL[/nom]As much as I hate to admit it, games like Guitar Hero and Rock Band actually translate better into brain stimulation than FPSs. Puzzle and RPG games (at least one's with some kind of strategy involved, mostly turn-based), I'm sure, are probably good brain stimulants as well.[/citation]
True, but have you ever played Unreal Tournament? That's a constant "challenging visuospatial task" if ever there was one.
I'm not surprised. There have been studies before that show crossword, sudoku, and tile games are all good for your brain. Pretty much anything that makes you think or problem solve is probably good for you. Video games are also good for reaction time and hand eye coordination.
This isn't surprising at all. It's pretty much already been established that games do this. Games like Guitar Hero and Dance Dance Revolution require a lot of coordination. Most games require at least some degree of problem solving skills and/or creating thinking to advance. The Lego Star Wars games come to mind. Basically every area is a puzzle where you have to figure out how to advance.
I am actually surprised nobody mentioned this before in the comments: it's not the time that you play tetris that makes the difference in the test girls, it's what they would do if they were not playing tetris. ALL the games and whatever challenges you to improve or even routinely solve puzzles instead of ... oo, facebooking all the time is good.
