Seeing is believing: Facial appearance, credibility, and attitude change

Abstract

One-hundred twenty-eight subjects (64 female, 64 male) viewed either a babyfaced or maturefaced female speaker delivering a persuasive communication, and also received information designed to make the speaker seem either untrustworthy or inexpert. Subjects indicated how much they agreed with the speaker's position and completed other measures concerning her appearance and their perceptions of her speech. Babyfaced speakers induced more agreement with their position than did maturefaced speakers when trustworthiness was in question, presumably because babyfaced speakers still appeared honest due to their babyish facial features. Conversely, maturefaced speakers produced more attitude agreement as compared to babyfaced speakers when expertise was questioned, perhaps because knowledgeability was still communicated via their mature countenance. Attitude change was not related to perceived likability, age, attractiveness, or communication skills of the speakers, or subjects' interest in the topic.
