Abstract

According to numerous research studies, when adults hear a statement twice, they are more likely to think it is true compared with when they have heard it only once. Multiple theoretical explanations exist for this illusory-truth effect. However, none of the current theories fully explains how or why people begin to use repetition as a cue for truth. In this preregistered study, we investigated those developmental origins in twenty-four 5-year-olds, twenty-four 10-year-olds, and 32 adults. If the link between repetition and truth is learned implicitly, then even 5-year-olds should show the effect. Alternatively, realizing this connection may require metacognition and intentional reflection, skills acquired later in development. Repetition increased truth judgments for all three age groups, and prior knowledge did not protect participants from the effects of repetition. These results suggest that the illusory-truth effect is a universal effect learned at a young age.

总结和评论

文章^[1]通过实验，研究了“被试多次重复听到一个陈述是否会提高被试相信这个陈述”这样一个问题。同时，对可能影响“重复－相信”关联度的因素，包含陈述本身是否正确、被试年龄（认知能力）、被试之前是否有相关的知识基础，等做了实验研究。

文章发现，无论陈述本身是否正确、被试年龄（认知能力）、被试之前是否有相关的知识基础，“重复－相信”关联都存在。
