To date there is limited information documenting growth patterns in the narratives of bilingual children with and without primary language impairment (PLI).
This study was designed to determine whether bilingual children with and without PLI present similar gains from kindergarten to first grade in the macro- and microstructure of stories told in Spanish and English.
METHODS & PROCEDURES: In this longitudinal study, 21 bilingual children identified with PLI were each matched to a bilingual typically developing (TD) peer on age, sex, non-verbal IQ and language exposure. During their kindergarten and first-grade years, children retold stories from wordless picture books in Spanish (L1) and English (L2).
OUTCOMES & RESULTS: Overall, TD children outperformed those with PLI on measures of macro- and microstructure at both time points. For the macrostructure measure, the TD group made significantly larger improvements in both languages from kindergarten to first grade than the PLI group. For microstructure, the TD children made more gains on their Spanish retells than their English retells. However, the PLI children's microstructure scores did not differ from kindergarten to first grade in either language. We found that macrostructure scores in Spanish at kindergarten predicted macrostructure scores in English at first grade when English experience was held constant. However, this same relationship across languages was not evident in microstructure.
CONCLUSIONS & IMPLICATIONS: TD and PLI children differed in the development of narrative macro- and microstructure between kindergarten and first grade. The TD bilinguals transferred conceptually dependent narrative skills easily, but then had to learn independently the nuances of each language to be successful using literate language. Because most children with PLI need more exposure to establish strong connections between their L1 and L2, they had more difficulty transferring their knowledge of literate language forms from one language to another.
迄今为止,关于双语儿童(包括有和没有主要语言障碍的儿童)叙述中成长模式的信息有限。
本研究旨在确定有和没有主要语言障碍的双语儿童在西班牙语和英语故事讲述的宏观和微观结构中,从幼儿园到一年级是否呈现出相似的增益。
在这项纵向研究中,21 名被诊断为有主要语言障碍的双语儿童与年龄、性别、非言语智商和语言接触相匹配的双语典型发育(TD)同伴相匹配。在他们的幼儿园和一年级期间,孩子们用西班牙语(L1)和英语(L2)复述无字图画书中的故事。
总体而言,TD 儿童在两个时间点的宏观和微观结构测量上均优于 PLI 儿童。在宏观结构测量方面,TD 组在从幼儿园到一年级的两个语言中均有显著的改进,而 PLI 组则没有。在微观结构方面,TD 儿童在西班牙语复述中比英语复述中取得了更大的进步。然而,在两种语言中,PLI 儿童的微观结构分数在从幼儿园到一年级的过程中没有差异。我们发现,当控制英语经验时,幼儿园西班牙语的宏观结构分数可以预测一年级英语的宏观结构分数。然而,这种跨语言的关系在微观结构中并不明显。
TD 和 PLI 儿童在幼儿园到一年级期间的叙事宏观和微观结构发展方面存在差异。TD 双语儿童可以轻松地将概念依赖的叙事技能转移,但随后必须独立学习每种语言的细微差别,以便成功使用书面语言。由于大多数有主要语言障碍的儿童需要更多的接触才能在他们的 L1 和 L2 之间建立强大的联系,他们在将书面语言形式的知识从一种语言转移到另一种语言方面遇到了更多的困难。
