It seems morally wrong and abusive to expose preschool children to violence for the sake of a study. This is nothing but common sense; however, it puts the "science" behind it, and we value and put great emphasis on the social sciences in our society :
When preschoolers watch educational programs instead of violent TV shows, they tend to be more compassionate and less aggressive, according to a study published Monday in the journal Pediatrics. The study
About 600 families were recruited and assigned to one of two groups. Parents in the first group were encouraged to substitute violent shows with educational and pro-social ones - shows that stressed compassion and cooperation.
Families were given monthly TV guides listing educational programming for their area: shows such as "Dora the Explorer," "Super WHY," "Sesame Street" and "It's a Big, Big World." Parents were also encouraged to watch TV with their kids.
The children went from watching a half-hour of violent programming a day to 23 minutes. Parents then increased educational viewing from about 30 to 43 minutes a day.
Families in the second group did not change their viewing habits.
"This is the first study to try to modify the viewing habits of preschool kids," says Dr. Vic Strasburger, spokesperson for the American Academy of Pediatrics. "That's one of the significances of this study."
After a year, researchers found that children watching less violent and more child-appropriate shows scored better on tests that measured cooperation, a willingness to share or compromise. They also had fewer incidents of aggressive behavior such as yelling and hitting.
"Although television is frequently implicated as a cause of many problems in children, our research indicates that it may also be part of the solution," the study notes.
