Many studies have shown that

  1. Playing a lot of violent games can lead to aggressive thoughts and feelings (Jeanne Funk, Craig Anderson, and Douglas).
  2. There is evidence that players who play even for a short time find that it is easier for them to think aggressive thoughts. Players of these games tend to get involved in more fights and do badly in school.
  3. Those who play for a long time tend to develop aggressive self-concepts adn are more likely to use aggressive means to solve problems. Physical violence may be accepted as a normal way of reacting.
  4. Players, especially boys, are more likely to think that others are hostile towards them. Players of violent games also tend to be less helpful and have less empathy for others.
  5. Players who live in the game worlds for a long time develop notions where they must watch their backs and they must kill in order not to be killed.
  6. Younger children are not mature in their thinking and do not know how to react differently in the real world. They transfer the rules or norms in the game world to real life.
  7. Younger children may not have developed strategies to deal with problems or conflicts. Hence, they are more likely to imitate characters in the games and solve problems faced in real life by violent means.
