This article compares lexical and grammatical abilities of a mental-age-matched sample of Italian preschoolers with Down syndrome (DS), specific language impairment (SLI), or typical development. Results showed that the children with DS or with SLI performed significantly worse than did the typically developing children. Although no significant differences emerged in lexical abilities and morphosyntactic comprehension abilities between the children with DS or with SLI, significant differences did emerge in morphosyntactic production capacities. Qualitative analysis of the morphosyntactic errors revealed strong similarities between the two groups. The results are discussed in terms of the role of verbal memory abilities and the linguistic features of Italian.
本文比较了患有唐氏综合征（DS）、特定语言障碍（SLI）或发育正常的意大利学龄前儿童在心理年龄匹配样本中的词汇和语法能力。结果表明，患有DS或SLI的儿童表现明显比发育正常的儿童差。虽然患有DS或SLI的儿童在词汇能力和形态句法理解能力方面没有显著差异，但在形态句法生成能力方面确实存在显著差异。对形态句法错误的定性分析显示两组之间有很强的相似性。本文从言语记忆能力的作用和意大利语的语言特征方面对结果进行了讨论。
