Ling, P. A., & Thomas, D. R. (1986). Imitation of television aggression among Maori and European boys and girls. New Zealand Journal of Psychology, 15 (1), 47-53.
Abstract: Examined the effects of viewing TV aggression on play behavior among 52 8-yr-old Maori and Pakeha children. Ss viewed 2 videotapes of aggressive and nonaggressive play behavior among male children, who were otherwise similar to the Ss in age, ethnicity, and socioeconomic status (SES). After viewing, Ss were allowed 10 min free play. During this time, their behavior was videotaped and rated on 15 discrete behaviors. Cluster analyses highlighted 2 major dimensions–physical aggression and activity. Exposure to either of the films increased the activity in play, but only exposure to the aggressive film increased interpersonal aggression. There were no significant differences between Maori and Pakeha children or between boys and girls. (PsycINFO Database Record (c) 2004 APA, all rights reserved)
