British researchers looked at a representative sample of over 11,000 kids born between 2000 and 2002, and results show those who watched television longer than three hours per day were more likely to develop antisocial behaviors such as fighting, stealing or bullying.
Researchers found a very small effect however, if they knew exactly what the children were watching it would be more helpful.
Mother were given a questionnaire in the study when their children were 5 and 7 years old, and this measured conduct problems, emotional symptoms, poor attention span, hyperactivity, difficulties making friends, and empathy and concern for others (which are considered “pro-social” behaviors).
Researchers found that watching more than three hours of TV per day was associated with a small but statistically significant increase in risk for antisocial behavior and conduct problems. However, it was not linked to emotional problems or attention issues.
