The Role of Interlocutor Behavior on Code Switching Patterns in Bilingual Children with and without Developmental Language Disorders

项目摘要/摘要 语码转换是一种常见的现象 在有典型和非典型语言的双语儿童中，包括有发展性语言的儿童 精神障碍(DLD)。语码转换要求说话人整合两种语言的形态句法特征； 因此，语言水平和社会因素是分析代码时要考虑的重要因素- 切换模式。目前对学习困难儿童语码转换的研究受到方法论的限制 问题，包括编码方法、启发式任务和儿童语言统计方面的问题 发展。为了解决这些问题，这项拟议的研究将使用全面的编码方法和 会话启发式任务考察有无学习障碍的双语儿童的语码转换模式。 这项研究将从语言学和社会语言学两个角度来理解语言能力 与这一现象相互作用。这项研究将涉及三个不同对话者的Diapix任务(英语- 仅限西班牙语和西班牙语-英语双语)。对话将被录音、转录和 编码过的。这项研究与美国国立卫生研究院(NIH)的愿景和使命声明相一致 为使用西班牙语-英语双语的临床医生提供先进诊断实践的基础知识 在全球范围内为儿童说话。最终，该项目旨在为该领域提供必要和创新的研究。 双语语言障碍，同时也培训了一名有前途的新调查员，在伦理，方法和 实质性的研究实践。

PROJECT SUMMARY/ABSTRACT Code-switching (alternation between language in a single utterance) is a common phenomenon observed among bilingual children with typical and atypical language, including children with developmental language disorder (DLD). Code-switching requires the speaker to integrate morphosyntactic features in both languages; therefore, language proficiency and social factors are important factors to consider when analyzing code- switching patterns. Current research on code-switching in children with DLD is limited by methodological issues, including problems with coding approaches, elicitation tasks, and accounting for children's language development. To address these issues, this proposed study will use a comprehensive coding method and a conversational elicitation task to examine code-switching patterns in bilingual children with and without DLD. The study will consider two perspectives, linguistic and sociolinguistic, to understand how language ability interacts with this phenomenon. The study will involve a Diapix task with three different interlocutors (English- only, Spanish-only, and bilingual Spanish-English). The conversations will be recorded, transcribed, and coded. This study aligns with the National Institute of Health's (NIH) vision and mission statement of seeking fundamental knowledge to advance diagnostic practices for clinicians working with bilingual Spanish-English speaking children globally. Ultimately, this project aims to provide essential and innovative research in the area of bilingual language disorder, while also training a promising new investigator in ethical, methodological, and substantive research practices.
