EFFECTS OF MESSAGE REPETITION AND POSITION ON COGNITIVE RESPONSE, RECALL, AND PERSUASION

Although the mere exposure effect has been researched widely, surprisingly little is known about the attitudinal and cognitive effects of message repetition. It was hypothesized that the sequence of topic-relevant thoughts generated in response to a (repeated) persuasive message would parallel attitude change. To test this prediction, 2 experiments were conducted. In Exp I, 133 undergraduates heard a communication either 0 (control), 1, 3, or 5 times in succession, rated their agreement with the advocated position, and listed the message arguments they could recall. In Exp II, 193 undergraduates heard a communication either 1, 3, or 5 times, rated their agreement, listed their thoughts, and listed the message arguments they could recall. In both experiments, agreement first increased, then decreased as exposure frequency increased (regardless of the position advocated), but agreement was unrelated to the recall of the message arguments. In Exp II, analyses of the listed thoughts revealed that counterargumentation decreased, then increased, whereas topic-irrelevant thinking increased as exposure frequency increased; as expected, only topic-relevant thoughts were related to agreement. Results are interpreted in terms of an attitude-modification model in which repetition and content of a persuasive advocacy affect the type and number of thoughts generated; these thoughts, in turn, affect the attitudinal reaction to the advocacy.
