DESCRIPTION (provided by applicant): In learning a language a child has to learn that certain words agree with certain endings (e.g., he does but not he do). Agreement morphology occupies a central role in language learning, and several language disorders are characterized by problems with agreement morphology (e.g. Specific Language Impairment and Autism). Thus, it is important to understand the mechanisms involved in learning and processing cases of agreement morphology as well as its normal time course of development. Although bilingualism is becoming the norm rather than the exception in the United States, agreement morphology has not been extensively investigated in bilingual populations. Bilingual children are often miscategorized as at risk for language disorders because little is known about bilingual language development compared to monolingual development. Differences in bilingual development are often interpreted as "atypical development". The primary objective of the proposed project is to document the normal time course of grammatical development in monolingual Spanish and bilingual (English/Spanish) infants, and to determine what types of agreement morphology dependencies infants are sensitive to. More specifically, this project examines when monolingual and bilingual infants are sensitive to non-adjacent morphosyntactic dependencies in the Noun Phrase (e.g., "the boys" but not "a boys") in Spanish and English using the Head-turn Preference Procedure technique. This research program is an extension of the PI's previous research on monolingual language development to a bilingual population (English/Spanish). Because this research proposal examines the normal time course of grammatical development in very young children, it contributes information on bilingual syntactic comprehension that could lead to the development of reliable measures of bilingual syntactic development and could also lead to more effective ways to differentiate late talkers from children with Specific Language Impairment (SLI). Thus, this research program is particularly relevant for the areas of Health Sciences and Communication Disorders. The data collected in this project will serve as the foundation for a broader research program that will investigate other types of morphosyntactic dependencies (e.g. he walks but not he walk) in monolingual and bilingual infants with the long-term goal of establishing the normal time course of grammatical development in bilingual and monolingual infants. PUBLIC HEALTH RELEVANCE: The results of this research will contribute information on bilingual language development that could lead to more effective ways to differentiate late talkers from children with Specific Language Impairment (SLI).

描述（由申请人提供）：在学习一门语言时，孩子必须学习某些单词与某些词尾一致（例如，he does但不是he do）。一致形态在语言学习中起着核心作用，一些语言障碍的特征是一致形态问题（如特异性语言障碍和自闭症）。因此，了解协议形态案例的学习和加工机制及其正常的时间发展过程是非常重要的。虽然在美国，双语正逐渐成为一种常态而非例外，但共识形态尚未在双语人群中得到广泛研究。双语儿童经常被错误地归类为有语言障碍的风险，因为与单语发展相比，我们对双语发展知之甚少。双语发展的差异通常被解释为“非典型发展”。该项目的主要目标是记录单语西班牙语和双语（英语/西班牙语）婴儿语法发展的正常时间过程，并确定婴儿对哪种类型的一致形态学依赖关系敏感。更具体地说，本项目使用头部转向偏好程序技术研究了单语和双语婴儿对西班牙语和英语名词短语（例如，“the boys”而不是“a boys”）中非相邻形态句法依赖的敏感程度。该研究项目是PI之前对双语人群（英语/西班牙语）的单语语言发展研究的延伸。由于本研究方案考察了幼儿语法发展的正常时间进程，它提供了双语句法理解的信息，这可能会导致双语句法发展的可靠措施的发展，也可能导致更有效的方法来区分晚说话者和特殊语言障碍（SLI）儿童。因此，该研究项目与健康科学和沟通障碍领域特别相关。本项目收集的数据将作为一个更广泛的研究项目的基础，该研究项目将调查单语和双语婴儿其他类型的形态句法依赖（例如，他走路但不是他走路），其长期目标是建立双语和单语婴儿语法发展的正常时间进程。
