The chapters report on various aspects of the research. A survey of 6,000 school-age children, parents, and teachers in England and Wales determined the extent to which children have viewed adult-oriented violence on home videos. A survey by the National Society for the Prevention of Cruelty to Children, conducted in December 1983 and January 1984, focused on the television viewing habits of those problem families served by the society. Other findings reported were obtained through psychiatric case studies and surveys of psychiatrists, pediatricians, and educators. Findings indicate that large numbers of school-age children have been exposed to videos containing extreme violence. Children with a tendency toward violence or aggressive behavior are attracted to the viewing of these films, and the evidence suggests a causal link between the viewing of violence and violent behavior. Parental attitudes strongly affect a child's video viewing patterns. Suggestions for future research are offered. Appended synopses of 10 violent videos, chapter references, and subject index.
