Abstract:  “The purpose of this study was to test the hypothesis that exposure to aggressive fantasy in an animated cartoon may intensify children’s impulses to aggression. Subjects were 36 first grade children, 18 girls and 18 boys, of middle class origin. The intensity of the child’s aggressive impulses were inferred from his responses to questions concerning desire to ‘play with’ or ‘pop’ a large yellow balloon held by a tester. The experimental findings clearly supported the major prediction.” From Psyc Abstracts 36:04:4FF61M. (PsycINFO Database Record (c) 2004 APA, all rights reserved)
