Two types of serial word recall tasks (full verbal recall and probed recall) were administered to 11 children with language impairment and 22 language-normal children matched for productive language or chronological age. The methods were designed to take into account age-related differences in the use of subvocal rehearsal, as measured by the word length effect. The word length effect was significant for all three groups in full recall, but not in probed recall, supporting the hypothesis that children with language impairment demonstrate limited capacity for processing verbal output. Discussion focuses on the importance of considering developmental factors in measuring short-term memory effects in children with language impairment.
As a result of this activity, the participant will be able to describe the phonological loop hypothesis and discuss the interactions between working memory and language performance in children with language disorders.
对11名语言障碍儿童和22名在语言表达能力或实际年龄上匹配的语言正常儿童进行了两种类型的系列单词回忆任务（完全言语回忆和提示回忆）。这些方法旨在考虑到通过单词长度效应衡量的与年龄相关的默读复述使用差异。在完全回忆中，单词长度效应在所有三组中都很显著，但在提示回忆中则不显著，这支持了语言障碍儿童在处理言语输出方面能力有限的假设。讨论集中在测量语言障碍儿童短期记忆效应时考虑发展因素的重要性。
通过本次活动，参与者将能够描述语音回路假设，并讨论语言障碍儿童工作记忆与语言表现之间的相互作用。
