When a group of children who have been watching television programs that include acts of violence is sent to play with a group of children who have been watching programs that do not include acts of violence, the children who have been watching violent programs commit a much greater number of violent acts in their play than do the children who have been watching nonviolent programs
Ttherefore, children at play can be prevented from committing violent acts by not being allowed to watch violence on television
Television has a harmful effect on society.
