二语词汇表征与加工中的形态影响

Morphological Structure in L2 Lexical Representation and Processing

为揭示形态结构对二语词汇表征与加工的影响,本研究采用SOA为200毫秒的启动任务考察了中国学习者对英语派生词加工过程中有意识阶段的加工特点,发现受试在该阶段的加工中存在形态结构的影响,且该影响与词形相似或意义联系的影响不同,表明他们的心理词库中存在独立的形态联系,这为二语词汇表征中形态结构的心理现实性提供了新的证据。这说明,一语和二语复杂词的加工受到相同的形态分解机制的影响。另外,本研究还从词汇学习的角度分析了学习者对语义晦涩派生词的表征与加工特点。

In order to reveal the morphological influence in L2 lexical representation and processing,this study used the overt priming paradigm( SOA = 200ms) to investigate the later stage of conscious processing in the time course of Chinese L2 learners' processing of English derived words. Significant morphological influence,which is distinctive from the orthographic similarity or semantic relatedness, was discovered in their processing, indicating the independent morphological relationship in L2 mental lexicon. This finding provides further evidence for the mental reality of morphological structure in L2 lexical representation. It is suggested that L1 and L2 representation and processing of the complex words are determined by the same mechanism of morphological decomposition. L2 learners' representation and processing of the semantically opaque words( e. g.,corner-corn) was also discussed from the perspective of vocabulary learning.
