Abstract: 29 male undergraduates viewed a control film (nonviolent with explicit sexual content) and 34 male undergraduates viewed an experimental film (violent with explicit sexual content). All Ss were then exposed to 2 brief clips of violence perpetrated by a man against a woman while their heart rates were monitored. Results indicate that heart rates for Ss exposed to the violent videotape were lower during the final 90 sec of each violent dependent measure film clip than controls. Although the violence-viewing Ss experienced no change in moods, control Ss experienced significant increases in hostility, anxiety, and depression during the dependent measure clips. Ss in the violence-viewing condition attributed less injury to the victims but greater responsibility to the perpetrators in the dependent measure clips, compared to control Ss.
