EFFECTS OF VOLUNTEERING FEAR AROUSAL AND NUMBER OF COMMUNICATIONS ON ATTITUDE CHANGE

Volunteers and nonvolunteers were assigned to 2 levels of fear arousal, high and low, and 2 levels of exposure to the persuasive messages, multiple and single, to complete a 2 * 2 * 2 factorial design. 120 male undergraduates were used as Ss. Data showed that volunteers complied to a significantly greater extent with the recommendations of the persuasive messages and were affected to a significantly greater degree by the arousal manipulations. The predicted interaction effect on attitude change between volunteers and nonvolunteers was supported. Increasing the number of exposures to the persuasive communication did not affect attitude-change scores. (17 ref.)
