Repetition-based credibility enhancement of unfamiliar faces.
Full Abstract
This experiment demonstrated that rating the credibility of nonfamous faces results in a significant increase in rated credibility on a subsequent encounter relative to new nonfamous faces. The degree of credibility enhancement is comparable for both honesty and sincerity ratings and at both short (2-day) and long (14-day) interrating intervals. Furthermore, credibility enhancement was independent of recognition; ratings were significantly higher for repeated faces, regardless of whether they were remembered. Although female faces were rated more credible than male faces, there was no gender difference in the degree of credibility enhancement with repetition. Conditional analyses revealed that actual, rather than perceived, repetition formed the basis of credibility enhancement. Future research should compare repetition effects on both credibility and affect as well as the durability of such effects over time.
