Abstract:  Tests the hypothesis that the effect of a film model on nursery school boys’ play behavior is greater for a child with no previous experience in the situation portrayed, than for one who has previously played there. In Exp. I, 10 Ss were shown a film, mildly frustrated and then allowed to play in the situation portrayed in the film. In Exp. II, 10 Ss were allowed to play in the same situation before seeing the film. A 3rd group of 10 Ss played in the experimental setting but were not shown the film. Results show that imitation is reduced when there is experience in the situation prior to presentation of the film model. When Ss returned 1 wk. later, there was no significant difference among the 3 groups. (PsycINFO Database Record (c) 2004 APA, all rights reserved)
