在本文中，我们报告了我们的研究结果，该研究旨在解决关于唐氏综合症认知和语言概况的两个广泛问题：(1)唐氏综合症患者的哪些功能领域特别受损？(2)唐氏综合症的语言和认知特征的哪些方面是唐氏综合症特有的？为了解决这些问题，我们关注唐氏综合症的三个方面——接受性语言、表达性语言和心理理论——并与脆性X综合征患者进行比较，脆性X综合征是一种与X相关的智力残疾。我们在所有三个方面都确定了唐氏综合症的缺陷，这些缺陷远远大于非语言认知方面的缺陷，并且这些缺陷与脆性X综合征患者不同。考虑了这些发现的临床意义。
In this paper, we report on the results of our research, which is designed to address two broad questions about the cognitive and linguistic profile of Down syndrome: (1) Which domains of functioning are especially impaired in individuals with Down syndrome? and (2) Which aspects of the language and cognitive profile of Down syndrome are syndrome specific? To address these questions, we focused on three dimensions of the Down syndrome profile--receptive language, expressive language, and theory of mind--and made comparisons to individuals with fragile X syndrome, which is an X-linked form of intellectual disability. We identified Down syndrome impairments on all three dimensions that were substantially greater than those seen in nonverbal cognition and that were not shared by individuals with fragile X syndrome. Clinical implications of these findings are considered.
