Phonological and semantic deficits in spoken word learning have been documented in children with language impairment (LI), and cues that address these deficits have been shown to improve their word learning performance. However, the effects of such cues on word learning during reading remain largely unexplored. This study investigated whether (a) control, (b) phonological, (c) semantic, and (d) combined phonological-semantic conditions affected semantic word learning during reading in 9- to 11-year-old children with LI (n = 12) and with typical language (TL, n = 11) from low-income backgrounds. Children were exposed to 20 novel words across these four conditions prior to reading passages containing the novel words. After reading, a dynamic semantic assessment was given, which included oral definitions, contextual clues, and multiple choices. Results indicated that the LI group performed more poorly than the TL group in phonological and combined conditions, but not in the control or semantic conditions. Also, a similar trend for both groups was suggested, with improved performance in the semantic and combined conditions relative to the control and phonological conditions. Clinical implications include a continued need for explicit instruction in semantic properties of novel words to facilitate semantic word learning during reading in children with LI.
语言障碍(LI)儿童在口语单词学习中存在语音和语义缺陷,已证明针对这些缺陷的线索可提高他们的单词学习表现。然而,此类线索对阅读过程中单词学习的影响在很大程度上仍未得到探索。本研究调查了(a)对照、(b)语音、(c)语义以及(d)语音 - 语义组合条件是否会影响来自低收入家庭背景的9至11岁LI儿童(n = 12)和典型语言(TL,n = 11)儿童在阅读过程中的语义单词学习。在阅读包含新单词的段落之前,让儿童在这四种条件下接触20个新单词。阅读后,进行动态语义评估,包括口头定义、上下文线索和多项选择。结果表明,LI组在语音和组合条件下的表现比TL组差,但在对照或语义条件下并非如此。此外,两组呈现出相似的趋势,相对于对照和语音条件,语义和组合条件下的表现有所改善。临床意义包括持续需要对新单词的语义属性进行明确指导,以促进LI儿童在阅读过程中的语义单词学习。
