Abstract

Conducted a meta-analysis of 30 studies, published 1971–1985, to examine the effect of exposure to pornography on aggressive behavior under laboratory conditions, considering a variety of moderating conditions (level of sexual arousal, level of prior anger, type of pornography, gender of S, gender of the target of aggression, and medium used to convey the material).

Results indicate that pictorial nudity induces subsequent aggressive behavior, that consumption of material depicting nonviolent sexual activity increases aggressive behavior, and that media depictions of violent sexual activity generate more aggression than those of nonviolent sexual activity. No other moderator variable produced homogeneous findings.
