Document Summary
Most research on attitude change looks at the effect of receiving one cognitive, affective, or behavioral intervention on attitudes, over a limited period of time. The simplest example of a multi-message environmental occurs when the same message is presented repeatedly o. 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.
