Abstract:A number of language acquisition patterns have been identified in the signing of a newly designated population of bimodal bilingual individuals—heritage signers. This article examines subject-referent tracking forms in the ASL (American Sign Language) narratives of six elementary-school-aged, native-signing, bimodal bilinguals made at different ages (5;02–6;09 and 6;07–8;02). These narratives are compared to those created by six Deaf counterparts (5;05–7;10) in a video-retelling task. The results show that, just as their Deaf peers, early bimodal bilinguals prefer nominal forms (for referent introduction and reintroduction) and null forms (for maintenance). However, the bimodal bilingual children increasingly diverge from their Deaf counterparts in the use of overt and fingerspelled forms. The increasing use of overt forms for maintenance and reintroduction is similar to patterns previously documented for heritage speakers, young unimodal bilinguals, and late bimodal bilinguals. Four of the six bimodal bilinguals showed an increased use of fingerspelled nominal forms for all discourse functions, yet these forms were rarely used by the Deaf children and instead were reserved for referent introduction. The greater prevalence of fingerspelled forms by the young bimodal

签名叙事中所指追踪的年轻双模双语发展：遗产签名者地位的进一步证明

摘要：在新指定的双峰双语个体群体——传统手语者的手语中，已经确定了许多语言习得模式。本文研究了在不同年龄（5;02-6;09 和 6;07-8; 6;07-8; 6; 07-8; 6; 07 - 8 02)。在视频复述任务中，将这些叙述与六名聋哑人 (5;05-7;10) 创作的叙述进行比较。结果表明，正如他们的聋人同龄人一样，早期的双峰双语者更喜欢名义形式（用于指称引入和重新引入）和无效形式（用于维持）。然而，双模双语儿童在使用明显和手指拼写形式方面越来越不同于他们的聋哑儿童。越来越多地使用公开形式进行维护和重新引入类似于以前记录的传统演讲者、年轻的单峰双语者和晚期双峰双语者的模式。六名双模双语者中有四名显示出在所有话语功能中更多地使用手指拼写的名义形式，但这些形式很少被聋儿童使用，而是保留用于指称介绍。年轻双峰的手指拼写形式的流行率更高
