DESCRIPTION (provided by applicant): This application is in response to Notice Number NOT-OD-09-058, Notice Title: NIH Announces the Availability of Recovery Act Funds for Competitive Revision Applications. The parent project investigates the development of bimodal bilingualism by studying sign language and spoken language in young deaf children with a cochlear implant (CI) and young hearing children in deaf families (codas). The research uses both longitudinal spontaneous production data and experimental tasks with children between the ages of 1 year, 6 months and 7 years to ask: How does early exposure to Sign Language and spoken language affect development in each modality in signing deaf children with a CI? Is the language development of bimodal bilinguals with fully accessible input constrained in ways similar to that of unimodal bilinguals? To what extent does the linguistic development of deaf children with CIs who receive early bimodal input resemble that of hearing bimodal bilinguals (codas)? We study the development of bimodal bilingualism by examining children's linguistic abilities in speech and sign. Because there is no commonly accepted writing system for ASL, sign researchers generally rely on a system of glossing; however, traditional transcription does not assign a consistent gloss for each sign, but different glosses depending on context and other aspects of the signed utterance. This means that it is very difficult for researchers to identify the locations of interest in a transcript using a search function to discover all occurrences of a particular sign. Analysis must proceed at a much slower pace of handsearching transcripts one utterance at a time. In order to facilitate and expand the analysis of data collected in the parent project, the competitive revision application proposes the development of an ID gloss lexicon containing the vocabulary items used most frequently by the children we are studying. ID glosses are labels chosen to represent each sign root systematically, so that every use of the sign has the same label, despite contextual or morphological differences which affect how the sign is interpreted. By using ID glosses in our transcripts, we will be able to conduct our analyses more efficiently, using a wider range of data. The proposed ID gloss lexicon will address the problem of transcript searchability and greatly facilitate the analysis of data to be collected in the parent project. PUBLIC HEALTH RELEVANCE: This project asks whether deaf children who have a cochlear implant can become bilingual in both spoken language and sign language in the same way that hearing children can become bilingual in speech and sign if their families use both languages. It is crucial for parents and educators to know about the ways in which this kind of bilingual situation can progress so that they can make informed choices. The competitive renewal supports this goal by making the analyses of child data more rapid and more accurate.

描述（由申请人提供）：本申请是对通知编号NOT-OD-09-058的回应，通知标题：NIH宣布恢复法案资金可用于竞争性修订申请。母项目调查双峰双语的发展，通过研究手语和口语在年轻的失聪儿童与人工耳蜗（CI）和年轻的听力儿童在聋人家庭（codas）。该研究使用纵向自发生产数据和实验任务与1岁，6个月和7岁之间的儿童问：如何早期接触手语和口语影响发展的每一种方式在签署聋儿CI？双模态双语者在完全可及输入下的语言发展是否受到与单模态双语者相似的限制？接受早期双模态输入的CI聋儿的语言发展在多大程度上与听力双模态双语者相似？我们通过考察儿童在言语和手势方面的语言能力来研究双模态双语能力的发展。由于没有普遍接受的书写系统，手语研究人员通常依赖于注释系统;然而，传统的转录并没有为每个符号分配一致的注释，而是根据上下文和签名话语的其他方面分配不同的注释。这意味着研究人员很难使用搜索功能来识别转录本中感兴趣的位置，以发现特定符号的所有出现。分析必须以慢得多的速度进行，一次一个话语地手工搜索抄本。为了促进和扩大在父项目中收集的数据的分析，竞争性修订应用程序提出了一个ID光泽词典的发展，其中包含的词汇项目，我们正在研究的孩子最常用的。ID注释是被选择来系统地表示每个符号根的标签，使得符号的每次使用都具有相同的标签，尽管上下文或形态差异会影响符号的解释。通过在我们的成绩单中使用ID注释，我们将能够使用更广泛的数据更有效地进行分析。拟议的ID注释词典将解决成绩单可搜索性的问题，并极大地促进了对母项目中收集的数据的分析。 公共卫生相关性：该项目探讨的问题是，植入人工耳蜗的失聪儿童是否可以成为口语和手语的双语者，就像听力正常的儿童如果他们的家庭使用两种语言，就可以成为口语和手语的双语者一样。家长和教育工作者必须了解这种双语情况的发展方式，以便他们能够做出明智的选择。竞争性更新通过使子数据的分析更快速、更准确来支持这一目标。
