Professor Ryuta Kawashima found that playing the computer game only stimulated the parts of the brain associated with vision and movement．The arithmetical exercise，on the other hand，stimulated brain activity in both the left and right hemispheres of the frontal lobe．The frontal lobe．which continues to develop in humans until the age of about 20．is the part of the brain that exercises self—control and stops anti-social and violent behaviour．
(31) However，another study in Britain has concluded that children who become addicted to computer and video games could actually be more intelligent than average．In some cases， they could be more certain to go to university and get higher- ranking jobs．The research 100ked at game addicts five years on．Many of the children had become highly intelligent， motivated，and successful people．
The government researcher，Jessica Harris，said that there was no evidence to show that the“Gameboy generation”had suffered any lasting damage．Although it is true that many of the games have high levels of aggression，this is also true for many sports，such as racing，karate，and wrestling，which all focus Oil the player’S level of aggression．(32) In fact, one part of the survey found that regular game use had a calming effect on the children because it provided an outlet for aggression and the open expression of competition．
