Kids who spend too much time at the computer are missing out on other activities fundamental to their physical, social, intellectual, and emotional development. Time spent in front of the computer or game console is time taken away from playing with friends, reading or doing a project with you, or playing outside.
Kids usually play video games alone, and too much time spent alone can foster social isolation.
Children who view more than ten hours of TV a week don't do as well in school as their peers who watch less. Habits left unchecked can become ingrained and are more difficult to change as children get older. If your child regularly plays games with plots based on violence and aggression, research shows he is at risk for increased aggressive behavior. It's important to remember, however, that video and computer games aren't all bad. Quality games give children the opportunity to practice problem solving and logic skills.
