L1 Role in Bilinguals’ Mental Lexicon: A Comparative Study between Chinese-English and Alphabetic Bilinguals
This study is to compare L1 (first language) roles between Chinese-English and alphabetic bilinguals’ mental lexicons through reviewing empirical studies. L1 lexicon plays an important role in L2 (second language) processing in two aspects for alphabetic bilinguals, automatic activation of similar L1 to sensory input of L2, and that of L1 translation equivalent. While for Chinese English learners, L1 lexicon basically influences L2 by equivalent activation only, and the effect may persist throughout their lives, which is dramatically different from the developmental pattern of alphabetic bilinguals. The differences may come from different typological distance between the two languages, different composition of L2 mental lexicon, and their unique English acquisition experience in China.
