The repetition of a stimulus often produces a shorter subjective duration than does the presentation of a novel item. To test whether familiarity mediates the repetition compression effect, the present study compared the influence of repeated words and pseudowords on apparent duration, using a duration discrimination task. We found a similar magnitude of temporal compression for the repeated-word and repeated-pseudoword conditions. When introducing a further experiment with two new conditions in which the standard-comparison pair shared a character at the first or second constituent position, we observed a shorter subjective duration for whole word (or whole pseudoword) repetition compared with the remaining conditions (i.e., first-character repetition, second-character repetition, and novel baseline). However, temporal compression for the first- and second-character repetitions was observed only for pseudowords but not for words. Our findings indicate that familiarity modulates the perception of duration in constituent character repetition. The results are discussed on the basis of the predictive coding theory.
与呈现新事物相比，重复刺激往往会产生更短的主观持续时间。为了测试熟悉度是否介导了重复压缩效应，本研究使用持续时间辨别任务，比较了重复单词和假词对表观持续时间的影响。我们发现，重复单词和重复假词条件下的时间压缩程度相似。当引入另一个包含两个新条件的实验时，即标准-比较对在第一个或第二个组成位置共享一个字符，我们观察到与其他条件（即首字符重复、第二个字符重复和新基线）相比，全词（或全假词）重复的主观持续时间更短。然而，仅在假词中观察到首字符和第二个字符重复的时间压缩，而在单词中未观察到。我们的研究结果表明，熟悉度会调节对组成字符重复中持续时间的感知。基于预测编码理论对结果进行了讨论。
