This article reviews experimental studies conducted since the 1970 pornography commission that have tested the effects of exposure to sexually explicit materials on attitudes and perceptions about rape. Studies ofshort‐termexposure to nonaggressive sexually explicit communications have yielded mixed results. When effects do exist for this material, they are both fewer and weaker than antisocial effects from sexuallyviolentmaterial. Studies of the effects oflong‐termexposure to nonviolent pornography have also yielded mixed results—some experiments finding increases in negative attitudes about rape, others showing no effects. However, one finding is consistent for both long‐and short‐term studies. Those that have included violent (slasher) film conditions have consistently found less sensitivity toward rape victims after exposure to these materials. The remainder of the paper is devoted to contradictions between the outcomes of long‐term studies and their possible solution.
