研究目的:探讨句子重复准确性是否可以通过参与者加工限制与句子结构的相互作用来解释。我们还测试了预测的程序缺陷假说(乌尔曼和Pierpont,2005年),prostituts是更困难的个人与发展性语言障碍(DLI)的参数。句子重复任务改变了句子的长度和使用的论点和论据。我们还对工作记忆和处理速度进行了测量。我们的回归模型集中在这些相互作用:组和参数状态;处理速度,长度和参数状态;和工作记忆容量,长度和参数status.ResultsLanguage能力组是一个显着的预测句子重复准确性,但没有相互作用的参数状态。加工速度与句子长度和论元状态有交互作用。工作记忆容量和其单独的相互作用与参数的状态和句子长度预测句子重复accuracy.ConclusionsMany adults与DLI可能有困难,由于他们的工作记忆的局限性,而不是他们的语言能力与patients。DLI患者常见的认知局限性更多地通过特定的句子结构来揭示,这表明了构建诊断更准确的句子重复任务的方法。补充材料https:doi.org/10.23641/asha.14963784
PurposeWe asked whether sentence repetition accuracy could be explained by interactions of participant processing limitations with the structures of the sentences. We also tested a prediction of the procedural deficit hypothesis (Ullman & Pierpont, 2005) that adjuncts are more difficult than arguments for individuals with developmental language impairment (DLI).MethodForty-four young adults participated, 21 with DLI. The sentence repetition task varied sentence length and the use of arguments and adjuncts. We also administered measures of working memory and processing speed. Our regression models focused on these interactions: group and argument status; processing speed, length, and argument status; and working memory capacity, length, and argument status.ResultsLanguage ability group was a significant predictor of sentence repetition accuracy but did not interact with argument status. Processing speed interacted with sentence length and argument status. Working memory capacity and its separate interactions with argument status and sentence length predicted sentence repetition accuracy.ConclusionsMany adults with DLI may have difficulty with adjuncts as a result of their working memory limitations rather than their language ability. Cognitive limitations common to individuals with DLI are revealed more by particular sentence structures, suggesting ways to construct more diagnostically accurate sentence repetition tasks.Supplemental Materialhttps://doi.org/10.23641/asha.14963784
