A press release from the 2008 convention of the American Psychological Association summarized papers presented on the topic of video games. The results seem mixed:
- playing video games can improve cognitive and perceptual skill
- surgeons who played video games requiring spatial skills and hand dexterity and then performed a drill testing these skills were significantly faster
- those who played more entertainment games did poorer in school and were at greater risk for obesity
- those playing violent games were more hostile, less forgiving and believed violence to be normal compared to those who played nonviolent games.
Many types of games and many different consequences.
