The Effects of Verbal Reports of Violence on Aggression

Forty male and 40 female volunteer college students were divided into two groups. Half were exposed to actual tape recorded verbal reports of violent events, and half to similar reports of nonviolent happenings. Ss who had been angered by insult prior to being exposed to violent tapes displayed significantly more aggression than Ss in an insult, nonviolent condition and Ss in a no-insult, violent condition on a subsequent "extrasensory learning" task supposedly involving shocks for incorrect responses. An unexpected finding was that Ss who had not been insulted administered significantly higher "shocks" after exposure to nonviolent reports than Ss in the no-insult, violent group. No significant sex differences were found. Results were interpreted as failing to support the catharsis hypothesis, and comparisons with the effects of visually witnessed violence were made.
