Abstract: Used L. Berkowitz’s basic research paradigm to test the effects of viewing film violence on aggressive behavior. 200 male undergraduates were angered by the E’s accomplice by means of electrical shocks. Ss then saw a nonviolent or violent film segment, or no film. The violent films were real or fictional and the violence was not explained, justified, or unjustified. Ss then were allowed to return shocks to the instigator. Measures of aggressive behavior included numbers of shocks returned and shock intensity. Results show that angered Ss who viewed justified real film violence returned significantly more and more intense shocks than angered Ss viewing unjustified real or fictional film violence, a nonviolent film, or no film. Findings suggest that the effects of increased aggression demonstrated for angered viewers of justified fictional violence are also applicable to angered viewers of real film violence. (15 ref.)
