为了探讨可能的解释报告的不准确性的儿童与特定语言障碍（SLI）的非词重复，我们比较了54名儿童与SLI和他们的同龄人的重复的数量和类型的错误，以及延迟和持续时间的反应。我们没有发现任何证据表明两组在听觉辨别或反应过程中存在差异，但我们确实发现了一些证据表明工作记忆中语音表征的形成或储存存在差异。由于重复准确性与语言的表达性而非接受性指标显著相关，因此我们假设问题在于工作记忆中语音表征的性质，而不是工作记忆中保持语音信息的能力。
To examine possible explanations of the reported inaccuracies of children with specific language impairment (SLI) on nonword repetition, we compared the repetitions of 54 children with SLI and their peers in terms of number and type of error as well as latency and duration of response. We found no evidence of differences between the groups in auditory discrimination or response processes, but we did find some evidence suggesting differences in either the formation or storage of phonological representations in working memory. Because repetition accuracy was significantly correlated with expressive, but not receptive, measures of language, we hypothesized that the problem lay with the nature of phonological representations in working memory and not with the ability to hold phonological information in working memory.
