How mixed language input affects child language development: case studies from Central Australia

三个土著社区的个案研究（维多利亚河唐斯的古林吉、埃佩纳拉的阿利亚瓦尔、坦南特溪的瓦鲁蒙古）将确定：（一）幼儿从传统土著语言、克里奥尔语和英语变体以及从涉及这些语言的代码转换中获得的语言输入;（二）对第一语言习得的影响;（3）多语环境下的语言迁移和保持过程，以及由此产生的目的语的传播或消失，以及新的混合语的出现。这是双语第一语言习得的一个未被探索的领域，对语言转换有理论意义，对语言保持有实际应用价值。

Case studies of three Aboriginal communities (Gurindji at Victoria River Downs, Alyawarr at Epenarra, Warumungu at Tennant Creek) will identify: (i) the language input young children receive from traditional indigenous languages, Kriol and English varieties, and from code-switching involving these languages (ii) the effect on first language acquisition; (iii) the processes of language shift and maintenance resulting from multilingual environments, and consequent transmission or loss of target languages, and emergence of new mixed languages. This is an unexplored area of bilingual first language acquisition, and has theoretical implications for language shift, and practical applications for language maintenance.
