An experimenter wanted to test the hypothesis that males are more creative than females. She also hypothesized that the male superiority in creativity would be heightened under conditions involving ego. The experimenter manipulated ego involvement by telling half of the participants that the creativity task was a measure of intelligence and the scores on the task would be posted on the bulletin board (high ego involvement). The investigator told the other half of the participants that she wanted to test the reliability of the creativity task she was developing and the participants should not put their names on the answer sheets (low ego involvement). Her test of creativity was an “unusual uses” test in which a person is given the name of an object (e.g., hammer) and has to write as many unusual uses for the object as possible in 5 minutes. Twenty-five males and 25 females participated in each of the two ego involvement conditions. The males were members of a senior ROTC class, and the females were recruited from a sorority pledge class. Two objects were used for the creativity task: an army compass and a monkey wrench. Participants were given five minutes for each object. The results indicated that the mean number of unusual uses for the objects for males was 4.1 under low ego involvement, and the mean was 7.6 under high ego involvement. The means for the females were 3.2 for low ego involvement and 2.4 for high ego involvement. Both main effects were significant as was the interaction. The experimenter concluded that her hypothesis was supported.
