我们研究了推理语言的使用与唐氏综合征（DS）的青少年在叙事故事的背景下，相对于年轻的典型发展（TD）的儿童和同龄的同龄人与脆性X综合征（FXS）匹配的非语言认知能力水平。参与者的叙述被编码为使用不同类型的推理语言。与TD或FXS患者相比，DS患者总体上使用的推理语言不成比例，尽管仅在DS-TD组比较中观察到的平均话语长度解释了组间差异。推理语言的使用模式在推理子类型和参与者群体中各不相同，平均话语长度在群体差异中起着重要作用。这些研究结果表明，潜在的综合征特异性的DS表型的推理语言使用的损伤，可以部分解释的表达句法能力的水平，并应在未来的研究中考虑。因此，在DS人群中的临床干预措施应在一定程度上针对推理语言和复杂句子结构的使用。
We examined inferential language use by youth with Down syndrome (DS) in the context of narrative storytelling relative to younger typically developing (TD) children and same-aged peers with fragile X syndrome (FXS) matched on nonverbal cognitive ability level. Participants' narratives were coded for the use of different types of inferential language. Participants with DS used proportionately less inferential language overall relative to their counterparts with TD or FXS, although mean length of utterance accounted for group differences observed for the DS-TD group comparison only. Patterns of inferential language use varied across inferential subtypes and across participant groups, with mean length of utterance playing a significant role in group differences. These findings suggest potential syndrome specificity to the DS phenotype regarding impairments in inferential language use that can be partially explained by level of expressive syntactic ability and should be considered in future research. Clinical interventions within the DS population, therefore, should target to some extent the use of inferential language and complex sentence structure.
