Studies and writings on the effects of television on children are reviewed and summarized. Topics are the young people's pattern of exposure to television, the nature of their viewing experience, the way they respond to television, and the direct effects on their values, attitudes and behavior. Research on the influence of television violence on aggressive and anti-social behavior is discussed at length; it is concluded that violent television entertainment increases the probability of subsequent aggressive behavior on the part of children and youth. The question of what, if any, action should be based on these findings is also discussed. (SK)
