Hanratty, M. A., O’Neal, E., et al. (1972). Effect of frustration upon imitation of aggression. Journal of Personality and Social Psychology, 21 (1), 30-34.

Abstract:  Assigned 30 1st grade boys to 1 of 3 treatments: (a) ss were frustrated and allowed to attack their frustrator, (b) ss were frustrated and allowed to attack another person, and (c) ss were not frustrated. 1/2 the ss had previously been shown an aggressive modeling film. According to prediction, ss who had seen the film and were frustrated displayed more imitative aggression. Among frustrated ss, there was no significant effect produced by the nature of the target. Results are discussed in terms of the influence of frustration on performance variables in observational learning. (17 ref.) (PsycINFO Database Record (c) 2004 APA, all rights reserved)
