The objective of this work was to analyze morphosyntactic development in a wide sample of children with Down syndrome (DS) (n = 92) and children with typical development (TD) (n = 92) with a mental age (MA) of 20 to 29 months. Children were individually matched for gender and MA (Analysis 1) and for vocabulary size (Analysis 2). Information about morphosyntax was obtained using an adaptation of the CDI for children with DS. In both analyses, the number of children with DS and with TD who combined words was similar. Analysis 1 showed that children with DS produced shorter utterances, with less morphosyntactic complexity and less morphological suffixes than children with TD, despite having the same mental age. The developmental pattern was similar, although slower in children with DS. Analysis 2 showed that the performance of children with DS was lower than the performance of children with TD in relation to morphosyntactic complexity and morphological suffixes.
这项研究的目的是分析92名唐氏综合征（DS）患儿和92名发育正常（TD）且心理年龄（MA）为20至29个月的儿童的形态句法发展情况。根据性别和心理年龄对儿童进行个体匹配（分析1），并根据词汇量进行匹配（分析2）。使用针对唐氏综合征患儿改编的沟通发展指标（CDI）获取有关形态句法的信息。在两项分析中，组合单词的唐氏综合征患儿和发育正常儿童的数量相似。分析1表明，尽管心理年龄相同，但唐氏综合征患儿的话语较短，形态句法复杂性较低，形态后缀较少。发育模式相似，尽管唐氏综合征患儿的发育速度较慢。分析2表明，在形态句法复杂性和形态后缀方面，唐氏综合征患儿的表现低于发育正常儿童。
