The study examined whether latency (i.e., the temporal gap between the aural input and the shadower's repetition) affected shadowing performance focusing especially on the error rates and the use of top-down processing in word recognition. The 81 high school students shadowed passages that contained a word that was syllabically and semantically deviant from the original one, and then were divided into three groups (i.e., close, middle, and distant shadowers) based on their mean latency. The statistical analyses showed that there was almost no association between the latency group and the error rates, but that the close shadowers were less likely to be affected by the abnormality of the target words and repeated the words exactly as they had heard them. Based on these results, the author proposed that delayed shadowing, with latency of longer than one second, may need to be redefined as shadowing with as long a latency as the learner can afford. Finally, two empirical implications were made for future research.
