Doob, A. N., & Kirshenbaum, H. M. (1973). The effects on arousal of frustration and aggressive films. Journal of Experimental Social Psychology, 9 (1), 57-64.

Abstract:  Conducted 2 experiments in which 44 high school students and 40 undergraduates were either frustrated or not, and then were shown either a film depicting aggression or a neutral film. In the 1st experiment, performance on a digit-symbol test was measured before and immediately after the manipulations. Ss who had either been frustrated or who had watched the aggressive movie performed better on the 2nd digit-symbol test than did Ss who had experienced neither or both of these manipulations. In the 2nd experiment, blood pressure was measured before and immediately after the manipulations. On various indices of arousal, the most arousal was shown for Ss who had been frustrated and who had watched the aggressive film. Ss who had not been frustrated and who had not watched the aggressive film showed the least arousal, and Ss who had experienced 1 or the other of these manipulations were in between. Given that performance on the digit-symbol test has been shown to be an inverted function of arousal, both of these experiments support the notion that the effects on arousal of frustration and aggressive movies are additive. This is directly counter to the idea that movies involving aggression are tension reducing for either frustrated or nonfrustrated Ss. (PsycINFO Database Record (c) 2004 APA, all rights reserved)
