This article compared the language profiles of adolescents with Down syndrome (DS) and children with specific language impairment matched for nonverbal cognitive ability, and investigated whether similar relationships could be established between language measures and other capacities in both groups. Language profiles were very similar: Expressive language was more affected than language comprehension, and grammar was more affected than vocabulary in both domains. Both groups were impaired on tests of grammatical morphology and phonological memory. There were some differences between the groups, but these could be attributed to other features of development of people with DS.
本文比较了唐氏综合征(DS)青少年与非语言认知能力相匹配的特定语言障碍儿童的语言特征,并研究了两组在语言测量与其他能力之间是否能建立相似的关系。语言特征非常相似:在两个领域中,表达性语言比语言理解受到的影响更大,语法比词汇受到的影响更大。两组在语法形态和语音记忆测试中均受损。两组之间存在一些差异,但这些差异可归因于唐氏综合征患者的其他发育特征。
