vior was seen. The results of these early studies indicated that children who had viewed the aggressive film were more aggressive in the playroom than those children who had not observed the aggressive person. The answer seems to be yes. Several studies have demonstrated that one exposure to a violent cartoon leads to increased aggression. During 1971, Hapkiewitz and Roden (1971:1583-1585) found that boys who had seen violent cartoons were less likely to share their toys than those who had not seen the violent cartoon. It seems clear from experimental studies that one can show increased aggressive behavior as a result of either long term or brief exposure to televised violence, but questions still arise about whether this increased aggressiveness seen in these experimental settings show in the children's daily lifes. FIELD EXPERIEMENTS In normal field-experiments, the investigator shows television programs in the normal viewing setting and observes behavior where it naturally occurs. The investigator controls the television programming either by arranging a special series of programs or by choosing towns that in the natural course of events receive different television programs. One of the early field-experiments in 1972 conducted by Stein and Friedrich (1972:202-317) for the Surgeon General's project dealt with 97 preschool children with a programming of either antisocial, prosocial, or neutral television programs during a four-week vi...
