Aggressiveness; Subliminal perception
This study evaluated the difference in displayed aggression in subjects randomly assigned to either a subliminal weapons effect condition or to a controlled condition. 30 students from a small public University in New Jersey signed up for the study to receive credit for their introductory psychology course. The subjects were then randomly assigned to one of the two conditions; the subliminal weapons effect conditioned consisted of a poster of "Scarface" holding a gun pointed toward the subject on the blackboard (the poster had a sign asking that it not be removed by a professor). The controlled condition had no stimuli on the blackboard. The subjects then completed a survey dealing with their attitude of the dining hall. The results showed that the subjects in the weapons effect condition showed a significantly higher level of aggression than the control group did.
