Abstract

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.

有和无 DLD 儿童句子回忆能力的预测因素:复杂性问题
我们利用106名患有和不患有DLD、操两种英语方言的儿童的档案数据,研究了词汇、形态能力、语音短期记忆(pSTM)和言语工作记忆(WM)对精确句子回忆、非语法重复和不正确时态产生的独立贡献。对于较简单句子的准确复述,DLD 组的成绩是由形态能力、pSTM 和 WM 预测的,而 TD 组的成绩是由词汇量,有时是由 pSTM 预测的。对于复杂句子,DLD 组的成绩由形态能力预测,而 TD 组的成绩由 pSTM 和 WM 预测。对于不合语法的重复和不正确的时态,形态学能力对两组都是一个影响因素,而 WM 也会影响 DLD 组的不合语法句子。因此,句子回忆需要多种资源,与非 DLD 儿童相比,DLD 儿童在句子复杂程度较低时需要更多不同的因素。

期刊介绍: A key publication in the field, Journal of Child Language publishes articles on all aspects of the scientific study of language behaviour in children, the principles which underlie it, and the theories which may account for it. The international range of authors and breadth of coverage allow the journal to forge links between many different areas of research including psychology, linguistics, cognitive science and anthropology. This interdisciplinary approach spans a wide range of interests: phonology, phonetics, morphology, syntax, vocabulary, semantics, pragmatics, sociolinguistics, or any other recognised facet of language study.
