Lando, H. A., & Donnerstein, E. I. (1978). The effects of a model’s success or failure on subsequent aggressive behavior. Journal of Research in Personality, 12 (2), 225-234.

Abstract:  Examined the influence of both aggressive and nonaggressive models who are successful or nonsuccessful in reducing aggression from an aggressive opponent. 25 male and 25 female college students viewed a same-sexed model interact with an aggressive opponent in a reaction time task. Half the Ss observed an aggressive model while the remaining Ss observed a nonaggressive model. For half the Ss the model was successful in reducing the aggressiveness of the opponent. Results indicate that both the model’s behavior and the consequences to the model (success/nonsuccess) were important determinants of subsequent aggression by the S. Results are discussed in terms of current research and theory in aggression control. (18 ref) (PsycINFO Database Record (c) 2004 APA, all rights reserved)
