On average, language and communication characteristics of individuals with Down syndrome (the most common genetic cause of intellectual disability) follow a consistent profile. Despite considerable individual variability, receptive language is typically stronger than expressive language, with particular challenges in phonology and syntax. We review the literature on language and literacy skills of individuals with Down syndrome, with emphasis on the areas of phonology, vocabulary, syntax, and pragmatics. We begin by describing the hearing, oral-motor, cognitive, social, and prelinguistic and early nonverbal communication characteristics of individuals with Down syndrome. We conclude with a discussion of clinical implications and research directions.
平均而言,唐氏综合征患者(智力残疾最常见的遗传病因)的语言和沟通特征呈现出一致的模式。尽管个体差异很大,但接受性语言通常比表达性语言更强,在语音和句法方面存在特别的挑战。我们回顾了关于唐氏综合征患者语言和读写能力的文献,重点关注语音、词汇、句法和语用学领域。我们首先描述唐氏综合征患者的听力、口腔运动、认知、社交以及语言前和早期非语言沟通特征。最后我们讨论临床意义和研究方向。
