Information and Attitudes: The Effects of Repetition and Amount of Information.
Ostrom, T. M.; And Others
This pair of papers share the focus of determining how differential exposure to information influences attitude formation and change. The first paper deals with the question of how differing amounts of information (set size) affect attitude formation. Set size effects in impression formation have not been obtained when examined in between-subjects design formats. This methodological difference has theoretical implications for interpreting the set size effect. Employing six set sizes, the between-subjects effect was obtained as predicted by both reference scale and information integration interpretations. A second experiment requiring judgement of 28 stimulus persons tested contrary predictions of the two explanations regarding the differences between earlier and later trials in the series. Supporting the reference scale interpretation, between-subjects set size effects diminished over trials. The second study looks at repetition effects. Repetition was predicted to increase positive reactions when highly similar messages were used. Advertisements were used as the stimulus message. Five similar ads were sequentially presented and attitude was measured by a cognitive response analysis of the thoughts recorded by subjects while attending to the message. In support of the hypothesis, a positive relationship was found between number of presentations and attitude. (Author/SJ)
