| Abstract: | Male college students (N = 96) were met by an experimental confederate who either agreed or disagreed with their opinion. The subjects were then given an opportunity to deliver electric shock to the confederate (victim), who responded to the shock with a facial expression of anger, fear, joy, or neutrality. The opinion condition had no effect, but the victim's facial expressions were clearly perceived by the subjects and two of them significantly influenced the amount of shock delivered to the victim by the subjects. The expression of enjoyment (smile) increased aggression while that of anger decreased aggression. The effects of the fear and neutral expressions did not differ from each other, and neither had a consistent significant effect on the amount of shock administered by the subjects. |
