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.

在听力正常的家庭出生的失聪儿童，很少有机会学习任何形式的语言，无论是口头语言还是手语，其情况往往是早期语言被剥夺。语言剥夺对认知、教育和生活结果具有长期的负面影响。我们的项目的目标是研究语言剥夺对手语中算术和语言数字使用的影响：这是一个未充分研究的重要课题。我们的研究可能会丰富语言和数字之间的关系的理论理解。这项研究的实际意义是为聋人教育专家提供更多关于聋人和语言经验的学生在数字认知方面的优势和劣势的信息。在本论文的四项研究中，量化通过手语在本地（L1）签署的美国手语（ASL）进行了比较，后期的第一语言学习者（LL1），先天性耳聋的个人谁没有获得自然的迹象在早期的生活。在前两项研究中，我们调查的因素，可能会影响数字收购的签名：（特定模态）数字标记在手语和数字系统之间的相互作用和同步形态（而不是顺序形态）的潜在复杂性。研究一探讨了世界手语的象似性和数字系统的结构特征。研究二考察了美国手语复数标记中象似数词系统和形态音系制约的相互作用。研究3采用数字Stroop测试范式，考察了数字在语言（ASL符号）和传统数学符号（阿拉伯数字）中的自动加工。研究4调查的生产和理解选择的同时，形态结构中使用的美国手语（标记确切和非确切的复数），在选定的分类器结构由L1和LL1学习者相比，通过numbers.This奖项公开的数字标记反映NSF的法定使命，并已被认为是值得通过使用该基金会的智力价值和更广泛的影响审查标准进行评估的支持。
