基于特征重组假说的二语习得研究述评

Review of Studies on Second Language Acquisition under the Feature Reassembly Hypothesis

特征重组假说是最简方案特征理论视角下的二语习得假说之一,核心思想是二语初态是一语语法功能和词汇形态的映射,学习者在习得过程中基于输入和普遍语法对特征进行添加或删除,最终完成二语特征重组和特征核查。本文从特征重组假说的基本内涵和理论发展入手,回顾了基于该假说的一些实证研究,并指出该假说对汉语二语习得研究的启示。文章认为,特征重组假说关注双语对比和二语习得过程,是继关注初态和终态的众假说后,最具解释力的二语习得假说之一。

The Feature Reassembly Hypothesis in second language acquisition originates from the Feature Theory of the Mini⁃malist Program.Its basic assumption is that the initial state of the second language(L2)is the first language(L1)where all the grammatical features are configurated according to L1.During the acquisition process,L2 learners add or delete L1 fea⁃tures in light of L2 input and Universal Grammar,and finally complete feature reassembly and feature checking for L2.This article introduces the arguments and theoretical development of the Feature Reassembly Hypothesis and reviews some empiri⁃cal studies with a special focus on L2 Chinese acquisition.It concludes that by making cross-linguistic comparisons and ad⁃dressing the acquisition process,the Feature Reassembly Hypothesis has more explanatory power than the hypotheses on the initial state and the end state of L2.
