Children with Down syndrome (DS) exhibit below average nonverbal intelligence and impaired language skills; however, their spoken narrative production is a relative strength.
We examined expressive language skills produced during fictional narrative retells and analyzed the unique contribution of expressive language skills to word-level reading and reading comprehension of children with DS.
The microstructure and macrostructure of fifteen, 8- to 18-year-old children with DS's narrative retells were analyzed. Receptive vocabulary, word-level reading, and reading comprehension also were measured.
Narrative microstructure analyses revealed restricted syntactic and semantic diversity. Further analyses of sentence complexity revealed that children with DS predominately produced prepositional phrases and produced more verbs than nouns. Narrative macrostructure analysis revealed participants use of episodic components; however, their stories did not include mental state references. Narrative microstructure contributed unique variance to word-level reading, whereas narrative macrostructure contributed unique variance to word-level reading and reading comprehension. Additionally, strong correlations were found between narrative skills and literacy skills.
Findings from this study support the use of narrative microstructure and macrostructure analyses as a valuable clinical tool to guide assessment and intervention planning for school-aged children with DS.
唐氏综合征(DS)患儿的非语言智力低于平均水平,语言技能受损;然而,他们的口语叙事能力是一项相对优势。
我们研究了虚构叙事复述过程中产生的表达性语言技能,并分析了表达性语言技能对DS患儿单词水平阅读和阅读理解的独特贡献。
分析了15名8至18岁DS患儿叙事复述的微观结构和宏观结构。还测量了接受性词汇、单词水平阅读和阅读理解能力。
叙事微观结构分析显示句法和语义多样性受限。对句子复杂性的进一步分析表明,DS患儿主要使用介词短语,动词的使用比名词更多。叙事宏观结构分析显示参与者使用了情节成分;然而,他们的故事中没有提及心理状态。叙事微观结构对单词水平阅读有独特的方差贡献,而叙事宏观结构对单词水平阅读和阅读理解都有独特的方差贡献。此外,叙事技能和读写能力之间存在很强的相关性。
本研究结果支持将叙事微观结构和宏观结构分析作为一种有价值的临床工具,用于指导DS学龄儿童的评估和干预计划。
