Politician: A major social problem is children hurting other children. The results of a recent experiment by psychologists establish that watching violent films is at least partly responsible for this aggressive behavior. The psychologists conducted an experiment in which one group of children watched a film of people punching Bobo the Clown dolls. A second group of children was not shown the film. Afterward, both groups of children played together in a room containing a Bobo doll. Most of the children who had seen the film punched the Bobo doll, while most of the other children did not.
