Evidence suggests that sleep may relate to oral language production in children with Down syndrome. However, these children are capable of using complex referential gestures as a compensation strategy for problems with oral production, and those with a greater productive oral vocabulary have less gestural vocabulary. The goal of this study was to explore whether sleep quality relates to oral and gestural production modalities in children with Down syndrome. We evaluated 36 preschool children with and without Down syndrome, paired by chronological age and gender, with similar sociodemographic backgrounds, using actigraphy to measure sleep behaviour and the Communicative Development Inventory for Down syndrome to measure vocabulary. Children with Down syndrome with better sleep efficiency showed more oral production but less gestural production. These results highlight the importance of sleep quality to language learning in children with Down syndrome.
有证据表明，睡眠可能与唐氏综合征儿童的口语产生有关。然而，这些儿童能够使用复杂的指代性手势作为口语产生问题的补偿策略，而且口语词汇量较大的儿童手势词汇量较少。本研究的目的是探讨唐氏综合征儿童的睡眠质量是否与口语和手势产生方式有关。我们通过活动记录仪测量睡眠行为，通过唐氏综合征沟通发展量表测量词汇量，对 36 名唐氏综合征和非唐氏综合征的学龄前儿童进行了评估，这些儿童按年龄和性别配对，具有相似的社会人口统计学背景。结果表明，睡眠效率较好的唐氏综合征儿童表现出更多的口语产生，但手势产生较少。这些结果强调了睡眠质量对唐氏综合征儿童语言学习的重要性。
