RT Journal Article SR Electronic T1 How to use a Spokesperson’s Smile Effectively JF Journal of Advertising Research JO J Advert Res FD WARC SP JAR-2021-015 DO 10.2501/JAR-2021-015 A1 CHUN-TUAN CHANG A1 HSIAO-CHING LEE A1 YU-KANG LEE A1 HUI-WEN CHANG YR 2021 UL http://www.journalofadvertisingresearch.com/content/early/2021/09/20/JAR-2021-015.abstract AB Drawing from the social-functional perspective, this research explored the differences in consumers’ responses to two types of spokesperson’s smile: broad and slight. The authors identified two boundary conditions: consumer self-construal (independent versus interdependent) and relationship norm (communal versus exchange). The results from two studies show that a spokesperson’s broad smile is more persuasive for consumers with interdependent self-construal in the communal relationship. By contrast, a spokesperson’s slight smile is more persuasive for consumers with independent self-construal in the exchange relationship. Processing fluency serves as the underlying mechanism. The results provide implications for marketers regarding how to use a spokesperson’s smile effectively.
