Thomas, M. H. (1982). Physiological arousal, exposure to a relatively lengthy aggressive film, and aggressive behavior. Journal of Research in Personality, 16 (1), 72-81.
Abstract: 50 male undergraduates viewed either a 15-min aggressive TV program excerpt or a neutral one. Half of the Ss in each group were then angered or treated in a neutral fashion by a confederate. Each S was allowed to retaliate by delivering electric shocks to the confederate as an evaluation of a problem solution he supposedly had completed. Heart rate was measured (a) before exposure to the TV program, (b) after exposure to the program, (c) immediately before delivering the shock, and (d) immediately after shock delivery. Results show that angered Ss who had seen the aggressive film were most aggressive toward the confederate and exhibited the lowest average pulse rates both before and after shock delivery. Findings are discussed in terms of their implications for arousal vs disinhibition conceptualizations of aggressive behaviors following exposure to TV violence.
