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.
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.
