Development of Bimodal Bilingualism

项目摘要 本研究通过对符号的研究来探讨双模态双语的发展 人工耳蜗植入（CI）和年轻聋儿的语言和口语 聋人家庭中的听力儿童。大多数研究都是针对患有CI的聋哑儿童进行的 一直关注他们口语的发展，无论是口头还是整体 通信程序。然而，没有人研究过手语的发展， 口语作为儿童双语的两个系统，与自然双语进行比较 CODA的情况。 本研究还通过比较双峰 双语两种语言对：英语和美国手语（ASL），和巴西 葡萄牙语（BP）和巴西手语（LSB）。通过在研究中包括两对， 研究的目的是更大程度的普遍性和更好地了解影响 语言的发展过程。 该研究使用纵向自发生产数据和实验数据， 1岁、6个月至7岁儿童的任务，以解决以下问题 三大问题： 问题1：早期接触手语和口语如何影响 在每一个模态的发展，在签署聋儿与CI？ 问题2：双峰双语者的语言发展是否有完全可及的输入 和单峰双语者一样受到限制 问题3：在何种程度上， 接受早期双峰输入类似于听到双峰双语者（尾声）？

PROJECT SUMMARY This 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). Most research conducted with deaf children with CIs has focused on their development of spoken language, whether they are in oral-only or total communication programs. However, none has examined the development of sign language and spoken language as two systems of a child bilingual, comparing them with the natural bilingual situation of codas. This study also breaks new ground by comparing the development of bimodal bilingualism in two language pairs: English and American Sign Language (ASL), and Brazilian Portuguese (BP) and Brazilian Sign Language (LSB). By including two pairs in the study the research aims for a greater degree of generalizability and a better understanding of the effects of particular languages on the process of development. 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 address the following three major questions: Question 1: How does early exposure to Sign Language and spoken language affect development in each modality in signing deaf children with a CI? Question 2: Is the language development of bimodal bilinguals with fully accessible input constrained in ways similar to that of unimodal bilinguals? Question 3: To what extent does the linguistic development of deaf children with CIs who receive early bimodal input resemble that of hearing bimodal bilinguals (codas)?
