项目摘要

Early language deprivation too often characterizes the circumstances of deaf children born in hearing families with little access to language in any form, spoken or signed. Language deprivation has long lasting negative effects on cognitive, educational and life outcomes. The goal of our project is to study the effects of language deprivation on the acquisition of numeracy and linguistic number use in sign language: an understudied and important topic. Our research can potentially enrich theoretical understanding of the relationship between language and number. The practical implication of the research is to provide specialists in deaf education with more information on the strengths and weaknesses of number cognition in students who are deaf and experience language at a late age. In the four studies of this dissertation, quantification through sign language in native (L1) signers of American Sign Language (ASL) is compared to that of late first-language learners (LL1), congenitally deaf individuals who had no access to natural sign in early life. In the first two studies, we investigate the factors that may influence number acquisition in signers: the potential complexity of (modality-specific) number marking in sign languages and the interaction between number systems and simultaneous morphology (rather than sequential morphology). Study 1 investigates iconicity and the structural properties of number systems of world’s sign languages. Study 2 investigates the interaction of iconic numeral system and morpho-phonological constraints in plural marking in ASL. Study 3 looks at the automatic processing of number expressed both linguistically (ASL signs) and in conventional mathematic symbols (Arabic digits) using the Number Stroop Test paradigm. Study 4 investigates the production and comprehension of selected simultaneous, morphological constructions used in ASL (that mark exact and non-exact plural) in selected classifier constructions by L1 and LL1 learners in comparison to overt number marking through numerals.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.

早期的语言剥夺经常表征在听力家庭中出生的死亡儿童的情况，而以任何形式使用或签名的语言几乎没有使用语言。语言剥夺对认知，教育和生活成果的负面影响持久。我们项目的目的是研究语言剥夺对以手语的数字和语言数量使用的获取的影响：一个理解和重要的话题。我们的研究可以潜在地丰富对语言与数量之间关系的理论理解。这项研究的实际含义是为聋人教育的专家提供有关聋哑学生数量认知和在较晚语言的学生的优势和缺点的更多信息。在本论文的四项研究中，将美国手语（L1）签名者（ASL）的手语量化与晚期第一语言学习者（LL1）的量化，先天性驱逐者的个人在早期生活中无法获得自然标志。在前两项研究中，我们研究了可能影响签名者数量获取的因素：符号语言中（特定于模态的）数字标记的潜在复杂性以及数字系统与简单形态（而不是顺序形态）之间的相互作用。研究1研究了世界标志语言数字系统的标志性和结构性。研究2研究了ASL中复数标记中标志性数字系统和形态表的约束的相互作用。研究3着眼于使用数字Stroop测试范式在语言上（ASL符号）和常规数学符号（阿拉伯数字）中同时表达的数字自动处理。研究4研究了L1和LL1学习者在选定的分类器构造中使用的ASL（标记和非精确性复数）中所选同时的形态结构的生产和理解，与通过众多奖项相比，该奖项反映了NSF的法定任务，反映了NSF的法定任务，并通过评估智力效果来诚实地对基础的Merit进行评估，并诚实地对其进行了评估。
