资料题：The author' s attitude toward TV violence is（　）。

It is disturbing that violence is concentrated in TV programs during the times of day when children are watching.The highest levels of aggression are noted during the early morning, after school, and on Saturday mornings.On the whole, the violent episodes children see are performed by the“good guys”as well as the“bad guys”and are rewarded about as often as they are punished.What is the effect of this extensive exposure to violent models? If social learning theory is correct, it ought to increase children's aggressive behavior because they will learn new kinds of violent actions and because they are“vicariously reinforced”by seeing the violent actor get rewarded for his aggression.The more violent television a child watches, the more aggressive he is likely to be.This is somewhat more true of young children, but it is found in studies of older children and adolescents as well.In addition to affecting behavior, viewing violence on TV affects children's attitudes about aggression.Joseph Dominick and Bradley Green berg found that elementary-school-aged children who watched many violent programs were more likely to think that aggression was a good way tosolve problems.The Dominick and Green berg study also showed that the effect of television was smaller when the parents opposed aggression and controlled it in the home.Parents who provide children with non-aggressive models in their own behavior may also reduce the impact.However, the overall effect seems clear from the research.
