摘要 我们检查了患有发展性阅读障碍或语言障碍 (LI) 的学龄儿童的口语句子理解能力，并与年龄匹配的年轻对照者进行比较。句子-图片匹配任务在三种不同的工作记忆（WM）负载、两种句法难度级别和两种句子长度下进行。还检查了语音短期记忆（STM）技能及其与句子理解能力的关系。当 WM 负荷最小化时，与年龄匹配的对照组和阅读困难组相比，LI 组在句子理解任务中的表现更差。在各组中，随着 WM 负荷的增加，句子理解能力普遍下降，但与年龄匹配的组相比，阅读障碍组的这种影响更为明显。此外，与年龄匹配的对照组相比，LI 组和诵读困难组的语音 STM 表现较差，并且在高要求的 WM 负荷下，语音 STM 和句子理解表现之间存在显着相关性。结果表明，阅读障碍患者存在微妙的句子处理困难，这可能是由于这些儿童的语音 STM 限制造成的。
ABSTRACT We examined spoken sentence comprehension in school-age children with developmental dyslexia or language impairment (LI), compared to age-matched and younger controls. Sentence–picture matching tasks were employed under three different working memory (WM) loads, two levels of syntactic difficulty, and two sentence lengths. Phonological short-term memory (STM) skills and their relation to sentence comprehension performance were also examined. When WM load was minimized, the LI group performed more poorly on the sentence comprehension task compared to the age-matched control group and the dyslexic group. Across groups, sentence comprehension performance generally decreased as the WM load increased, but this effect was somewhat more pronounced in the dyslexic group compared to the age-matched group. Moreover, both the LI and dyslexic groups showed poor phonological STM compared to the age-matched control group, and a significant correlation was observed between phonological STM and sentence comprehension performance under demanding WM loads. The results indicate subtle sentence processing difficulties in dyslexia that might be explained as resulting from these children's phonological STM limitations.
