The aim of this study was to compare narrative abilities in children with specific language impairment (SLI) who are monolingual and those who are dual language learners.
The participants were 26 children with SLI, 14 monolingual English speakers and 12 dual language learners. The dual language learners were English dominant and spoke a variety of other languages in the home. The two SLI groups were compared using standardized tests and measures from two narrative samples.
Compared to the monolingual children, the dual language learners achieved lower scores on standardized tests of morphosyntax but not on measures of language form derived from the narrative samples. Both groups achieved below average scores on productivity, narrative structure, literate language, and language form measures from the narrative samples.
The data suggest that narrative samples can be a sensitive way to assess the language skills of dual language learners with specific language impairment. Furthermore, the findings are consistent with the position that English standardized tests may be a biased assessment measure when used with dual language learners, particularly for the assessment of expressive morphosyntactic skills.
Readers will be able to (1) describe the narrative abilities of typically developing dual language learners; (2) describe similarities between the narrative abilities of children with SLI who are monolingual and dual language learners; (3) identify ways to analyses narratives at a variety of levels.
本研究旨在比较单语和双语学习的特定语言障碍(SLI)儿童的叙事能力。
参与者为26名患有SLI的儿童,其中14名单语英语使用者和12名双语学习者。双语学习者以英语为主,在家中说多种其他语言。使用来自两个叙事样本的标准化测试和测量方法对两个SLI组进行比较。
与单语儿童相比,双语学习者在形态句法标准化测试中的得分较低,但在来自叙事样本的语言形式测量中得分不低。两组在叙事样本的产出、叙事结构、书面语言和语言形式测量方面的得分均低于平均水平。
数据表明,叙事样本可能是评估患有特定语言障碍的双语学习者语言技能的一种敏感方式。此外,研究结果与以下观点一致:当与双语学习者一起使用时,英语标准化测试可能是一种有偏差的评估方法,特别是在评估表达性形态句法技能时。
读者将能够(1)描述典型发展的双语学习者的叙事能力;(2)描述单语和双语学习的SLI儿童叙事能力之间的相似性;(3)确定在多个层面分析叙事的方法。
