Witness and nonwitness children's violent and peaceful behavior in different types of simulated conflict with peers.

The violent and peaceful behaviors of 115 children who had or had not witnessed domestic violence were measured in five types of simulated conflict. Witnesses did not differ from nonwitnesses in conflicts involving limited resources, jealousy over possessions, or intimidation; witnesses were significantly more violent in conflicts involving aggression and exclusion. The most violent responses were found among abusers' sons who had been excluded by peers.
