Using archival data from 106 children with and without DLD who spoke two dialects of English, we examined the independent contributions of vocabulary, morphological ability, phonological short term memory (pSTM), and verbal working memory (WM) to exact sentence recall, ungrammatical repetition, and incorrect tense production. For exact repetitions on simpler sentences, performance of the DLD group was predicted by morphological ability, pSTM and WM, while that of the TD group was predicted by vocabulary and sometimes pSTM. On complex sentences, performance of the DLD group was predicted by morphological ability, and the TD group was predicted by pSTM and WM. For ungrammatical repetitions and incorrect tense, morphological ability was a factor for both groups, with WM also affecting the DLD group for ungrammatical production. Thus, sentence recall taxes multiple resources, with more and different factors being taxed at lower levels of complexity for children with DLD than those without.

有和没有 DLD 的儿童句子回忆表现的预测因子：复杂性很重要


使用来自 106 名说两种英语方言的患有和没有 DLD 的儿童的档案数据，我们检查了词汇、形态能力、语音短期记忆 （pSTM） 和语言工作记忆 （WM） 对准确句子回忆、不语法重复和不正确时态产生的独立贡献。对于简单句子的精确重复，DLD 组的表现由形态能力、 pSTM 和 WM 预测，而 TD 组的表现由词汇（有时是 pSTM）预测。在复杂句中，DLD 组的表现由形态学能力预测，TD 组的表现由 pSTM 和 WM 预测。对于非语法重复和不正确的时态，形态能力是两组的一个因素，WM 也影响 DLD 组的非语法产生。因此，句子回忆会占用多种资源，与没有 DLD 的儿童相比，更多和不同的因素对 DLD 儿童的复杂程度征税。
