4 Scientific research indicates that aggression increases immediately after viewing a violent TV show or movie for 20 minutes. Viewers of media violence are taught that the best way to resolve conflicts is physical retaliation. The longer you learn this, the more difficult this learned behavior is to change. In most video games, the player decides when and how to use violence and whom to attack. And users can now customize the game, inserting images of real people and locations to make the activity even more realistic.
Active participation increases the learning process because it requires more attention.
Repetition increases learning. The addictive nature of video games means the player repeatedly practices the skills. Twenty-nine percent of boys report having felt addicted to video games. The average seventh-grader spends at least four hours per week playing video games, half of which are likely to be violent. Violent video game players were found to be 43 percent more likely to communicate a violent thought than those who had just played a nonviolent video game.
