The effects of imagery‐evoking radio advertising strategies on affective responses

A debate in the marketing literature concerning the relative effectiveness of various imagery-evoking strategies in influencing consumer responses to advertising has been unresolved. This study examined the effects of three imagery-evoking strategies commonly used in radio advertising—sound effects, vivid verbal messages, and instructions to imagine—in influencing mental imagery, ad-evoked feelings, and attitude toward the ad. The theoretical basis for the study is an imagery model based on propositional representations theory. Consistent with the implications of the theory, of the three strategies, sound effects had the greatest impact on imagery and affective responses. Compared with sound effects, a vivid verbal message had a slightly weaker influence. Instructions to imagine, however, had a very weak impact on imagery and no significant influence on affect. Finally, the results indicated that the three strategies interacted with one another. © 1997 John Wiley & Sons, Inc.
