Horton, R. W., & Santogrossi, D. A. (1978). The effect of adult commentary on reducing the influence of televised violence. Personality and Social Psychology Bulletin, 4 (2), 337-340.

Abstract:  Compared the effects of 3 types of adult commentary (antiaggressive, nonaggressive, and neutral) presented during a violent TV show to a nonviolent control film in 32 2nd-5th grade boys. Ss’ latency in seeking adult help when witnessing “real” violence among other Ss was measured. Antiaggressive and nonaggressive commentary Ss were significantly faster in summoning help than were neutral commentary Ss. Control Ss did not differ from other Ss in responsivity. Results are interpreted within a cognitional framework. (10 ref) (PsycINFO Database Record (c) 2004 APA, all rights reserved)
