本研究调查了唐氏综合症（DS）儿童的语言和交流发展。更具体地说，目的是检查发展早期阶段的言语理解、言语产生和手势产生之间的关系。 40 名 DS 儿童（年龄范围：10-49 个月）和 40 名发育正常儿童（年龄范围：8-17 个月）参与了本研究。患有 DS 的儿童来自两个意大利卫生中心。 DS 儿童的交际和语言发展是通过执行意大利版麦克阿瑟交际发展量表来测量的。与正常发育的儿童相比，DS 儿童的发育阶段严重延迟。在这些儿童中，言语理解和表达之间出现了分离，有利于理解，而声音词汇理解和手势表达之间则发现了同步发展。先前报告的这些儿童的个体差异在所有检查领域也很明显。患有 DS 的儿童与正常发育的对照儿童在言语产生的词汇理解方面没有显着差异。然而，两组在手势发育方面存在显着差异，这表明 DS 儿童与匹配的对照组相比，在单词理解方面具有“手势优势”。讨论了这种解离特征的一些可能原因。
This study investigated the development of language and communication in children with Down syndrome (DS). More specifically, the aim was to examine the relations among verbal comprehension, verbal production, and gesture production in the very early stages of development. Forty children (age range: 10-49 months) with DS and 40 children with normal development (age range: 8-17 months) participated in this study. Children with DS came from two Italian health centers. The communicative and linguistic development of children with DS was measured by administering the Italian version of the MacArthur Communicative Development Inventory. The children with DS were severely delayed when compared with normally developing children in reaching the developmental stages. In such children a dissociation emerged between verbal comprehension and production, in Favor of comprehension, whereas a synchronous development was found between vocal lexical comprehension and gestural production. The individual differences previously reported in these children are also evident in all domains examined. There were no significant differences between children with DS and typically developing controls matched for lexical comprehension on verbal production. However the two groups differed significantly in gestural development, suggesting a "gesture advantage" in children with DS compared With controls matched For word comprehension. Some possible reasons For this dissociative profile are discussed.
