Abstract

Purpose: The study aimed to understand how bilingual children with typical language development (TLD) and those with developmental language disorder (DLD) use frequent word co-occurrences in their narratives.

Method: We studied the change over time in the word co-occurrences used by 30 Spanish-English bilingual children with and without DLD (experimental group). An additional normative group consisted of 98 TLD Spanish-English bilingual first graders. Children narrated two Spanish and two English stories in kindergarten and first grade. Employing a Python program on the transcribed narratives, we extracted all adjacent two-word and three-word co-occurrences. From the normative group, the 90 most frequently occurring two-word and 90 most frequently occurring three-word co-occurrences were extracted. The type and tokens of word co-occurrences each child in the experimental group produced out of the 180 identified word co-occurrences were analysed.

Result: Overall, children at first grade produced more word co-occurrences types than in kindergarten. Children with DLD used fewer types of word co-occurrences but produced them as often as than their TLD peers. Children with DLD increased their word co-occurrences from kindergarten to first grade at the same rate although at a lower frequency. Children in both groups produced similar types and tokens of word co-occurrences in both Spanish and English, except tokens of two word co-occurrences. Children produced two word co-occurrences more often in English than in their Spanish narratives.

Conclusion: The results shed light on children with DLD's deficits in production of word co-occurrences, indirectly reflecting possible deficits in statistical pattern detection.

有发育性语言障碍和无发育性语言障碍的西英双语儿童词语共同出现率的发育变化。
目的:本研究旨在了解具有典型语言发育(TLD)和发育性语言障碍(DLD)的双语儿童如何在他们的叙述中使用频繁出现的词语:我们研究了 30 名患有和未患有发育性语言障碍的西班牙语-英语双语儿童(实验组)在使用共现词方面随时间发生的变化。另一个标准组由 98 名患有 TLD 的一年级西英双语学生组成。孩子们讲述了幼儿园和一年级的两个西班牙语故事和两个英语故事。我们使用 Python 程序对转录的叙述内容进行了提取,提取了所有相邻的两个词和三个词的共现。我们从标准组中提取了 90 个出现频率最高的双字共现词和 90 个出现频率最高的三字共现词。分析了实验组每个儿童在 180 个已识别的词语共现中产生的词语共现的类型和标记:结果:总体而言,一年级儿童比幼儿园儿童产生了更多的词语共现类型。有 DLD 的儿童使用的词语共现类型较少,但与有 TLD 的儿童相比,他们产生词语共现的频率相同。从幼儿园到一年级,患有 DLD 的儿童的词语共现次数增加的速度相同,但频率较低。两组儿童在西班牙语和英语中产生的词语共现类型和词块相似,但两个词语共现的词块除外。儿童在英语叙述中出现两个词共同出现的频率高于在西班牙语叙述中出现的频率:研究结果表明,患有 DLD 的儿童在产生词语共现方面存在缺陷,这间接反映了他们在统计模式检测方面可能存在缺陷。

期刊介绍: International Journal of Speech-Language Pathology is an international journal which promotes discussion on a broad range of current clinical and theoretical issues. Submissions may include experimental, review and theoretical discussion papers, with studies from either quantitative and/or qualitative frameworks. Articles may relate to any area of child or adult communication or dysphagia, furthering knowledge on issues related to etiology, assessment, diagnosis, intervention, or theoretical frameworks. Articles can be accompanied by supplementary audio and video files that will be uploaded to the journal’s website. Special issues on contemporary topics are published at least once a year. A scientific forum is included in many issues, where a topic is debated by invited international experts.
