项目摘要

Language deprivation is common among individuals born deaf when they do not have early access to a sign or spoken language, which causes deficits in their ultimate language performance. Understanding the nature of these age of acquisition effects on sentence structure can illuminate the underlying mechanisms of the critical period for language development and provide clinicians and educators with important information about the nature of language deprivation in deaf students. The current proposal examines the effects of early language deprivation on language processing at the basic phrasal level. The participants are deaf adults and adolescents who experienced minimal early language and began to acquire American Sign Language (ASL) as their first language (L1) later in life. Study 1 investigates longitudinal development of basic word order in four case studies. Study 2 investigates whether late L1 learners rely on syntactic cues or use alternative strategies when comprehending and producing simple mono-clausal sentences using a sentence-picture verification task and an elicited word order production task. The participants are a group of deaf late L1 learners (n = 10, Age of Acquisition, AoA 8) and a control group of deaf native signers (n = 10). Study 3 investigates these phenomena with adolescents who are deaf native signers (n = 10) and late L1 learners with early AoA (n = 10, AoA 4-6), as well as adolescents who are late L1 learners (AoA 8-10). This manipulation of AoA investigates the questions of 1) whether childhood vs adolescent L1 AoA has different effects on sentence processing strategies and 2) when late L1 learners reach a stable stage of processing basic phrasal structure.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

语言剥夺是在聋哑人无法尽早使用标志或口语的个人中常见的，这会导致其最终的语言表现不足。了解这些获取时代对句子结构的效果的性质可以阐明语言发展关键时期的基本机制，并为临床医生和教育者提供有关聋人语言剥夺性质的重要信息。当前的提案研究了早期语言剥夺对基本短语层面语言处理的影响。参与者是聋哑成年人和青少年，他们经历了最少的早期语言，并开始以后来的生活中获得美国手语（ASL）作为第一语言（L1）。研究1研究了四个案例研究中基本单词顺序的纵向发展。研究2调查了晚期L1学习者是使用句子验证任务和引起的单词订单生产任务来理解和生产简单的单袋装句子时依靠句法提示还是使用替代策略。参与者是一组聋哑的L1学习者（n = 10，获取年龄，AOA 8）和对照组的聋哑签名者（n = 10）。研究3与聋哑人签名者（n = 10）和具有早期AOA的晚期L1学习者（n = 10，AOA 4-6）以及晚期L1学习者（AOA 8-10）的青少年一起研究了这些现象。 This manipulation of AoA investigates the questions of 1) whether childhood vs adolescent L1 AoA has different effects on sentence processing strategies and 2) when late L1 learners reach a stable stage of processing basic phrasal structure.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
