Ten years ago studies concluded that players of video games were very intelligent and motivated people. They got good results at school and at work. In those days, video games were quite simple, so what about the more complex games of today? Many children start to play video games at seven. For most of them this is not a problem, but some of them become addicts. Addiction to games led to other problems such as stealing money to buy new games, failing to do homework or not going to school. In another study, scientists at Japan`s Tohoku University looked at the brain activity of hundreds of students as they played a Nintendo game. They compared this with brain activity of other students doing maths. The results were surprising. The computer game only stimulated those parts of brain related to vision and movement, but not parts of the brain which are important for behaviour, memory and learning.
