Elliot Aronson mentions a few studies in his "The Social Animal" book starting on page 263. I'll just briefly list the studies mentioned, in case anyone is interested:
- Bushman, B. (2002). Does venting anger feed or extinguish the flame? Catharsis, rumination, distraction, anger and aggressive responding. Personality & Social Psychology Bulletin, 28, 724-731
- Patterson, A. (1974, September). Hostility catharsis: A naturalistic quasi-experiment. paper presented at the annual convention of the American Psychological Assiociation, New Orleans.
- Geen, R. (1981). Spectator moods at an aggresive sports event. Journal of Social Psychology, 3, 217-227.
- Glass, D. (1964). Changes in liking as a means of reducing cognitive discrepancies between self-esteem and aggression. Journal of Personality, 32, 531-549.
- Davis, K.E., & Jones, E.E. (1960). Changes in interpersonal perception as a means of reducing cognitive dissonance. Journal of Abnormal and Social Psychology, 61, 402-410.
The conclusion seems to be a resounding no. Venting anger does not help, neither verbally nor physically.
