The Influence of Repetitive Health Messages and Sensitivity to Fluency on the Truth Effect in Advertising
研究了重复健康广告信息如何影响消费者对信息真实性的主观判断（真相效应），发现消费者对处理流畅性的敏感性会增强这一效应，尤其是当消费者被鼓励关注自身感受时。
Although merely repeating a product claim does not influence the objective validity of the claim, it often increases the subjective validity of the claim (the truth effect). Research notes that the truth effect plays an important role in health advertising. The present research investigates the moderating role of sensitivity to feelings of fluency (or processing ease) on the truth effect. The truth effect was more pronounced when the need for affect was high rather than low (Study 1) and when consumers were primed to trust their feelings (Study 2). Finally, Study 3 and Study 4 replicate these findings using advertising appeals. Advertisements that encourage consumers to focus on their feelings increase susceptibility to the truth effect.
