The effects of three types of aggression on vascular processes.

"Eighty college-age-subjects underwent either a frustrating or nonfrustrating experience and subsequently were placed in one of four aggression-conditions: Physical, Verbal, Fantasy, or No Aggression. The intent of this 2 X 4 factorial design experiment was to measure the effects of each type of aggression on frustration-produced-elevations in systolic blood pressure and heart rate. The results indicated that frustrated subjects who were given an opportunity to physically or verbally aggress against the frustrator, manifested returns on both physiological measures to the levels of the Low Frustration control subjects. Frustrated subjects in the Fantasy and No Aggression conditions exhibited significantly elevated systolic pressures and heart rates at the post-aggression-recording of these measures."
