Researchers found kids who watch too much TV are more likely to exhibit anti-social and criminal behavior when they become adults.
The study`s authors found the risk of a criminal conviction in early adulthood increased 30 percent with every hour children watched TV, on an average weeknight.
The second study found that limiting how much aggressive behavior preschoolers see on television can improve their conduct.
Kids in two groups watched the same amount of television, the only change was the type of programming.
The children who watched the better quality programming demonstrated significantly less aggression than the other group.
