This study examined whether exposure to pornography lead to aggression, utilizing pornographic video
excerpts and measuring participants' aggression by the number of human faces chosen as targets during a dart-throwing
decision task. Male college students (n = 120) were randomly assigned into one of three experimental groups who viewed
the sexually explicit material (nonviolent, sadomasochistic, or violent pornography) or to a control group who viewed
nonsexual, nonviolent material. Each participant could then behave aggressively, or not, in a dart-throwing decision task
offering pictures of human faces as possible targets. The facilitative effect of aggression was significant for all three
groups exposed to pornography. The effect was especially conspicuous for those groups exposed to violent pornography.
