Document Summary

Cacioppo and petty: conducted two experiments that examined this message environment. University students heard a message containing many strong arguments in favor of an increase in university spending. Participants received the message either once, three times, or five times and then rated their attitudes toward the recommendation. Participants attitudes and issue-relevant thoughts were more consistent with the message when it was presented 3x than when it was only presented once. Participants were significantly less persuaded when the messaged was presented 5x than when it was presented 3x. Repetition increased persuasion only to a point, after which it decreased persuasion. They interpreted this result using the elaboration likelihood model of persuasion. They suggested that repetition increased the ability to comprehend the strong arguments to a point, after which the message became tedious. Tormala and petty: exposed participants to a persuasive message promoting a department store.
