第二语言学习者形态复杂词的加工机制

大多数语言中, 形态复杂词所占的比例很高。形态复杂词形-义映射的规律性使得读者不仅能直接从心理词典中提取整词语义, 还可以利用形态规则来建构词语的语义。研究发现, 母语者可以利用形态规则来加工复杂词, 但第二语言(二语)学习者的研究结果存在较大的分歧, 且表现出和母语者不一样的结果模式。基于补充学习系统理论和情景性二语者假设, 我们尝试提出了二语形态复杂词加工机制的观点, 并据此解释研究分歧出现的原因。未来的研究需要探究词汇形态家族大小等因素对二语形态复杂词加工的影响, 以及揭示二语形态复杂词加工的神经机制。

The processing mechanism of morphologically complex words for second language learners

Most languages of the world have a high proportion of morphologically complex words that are composed of two or more morphemes.When processing morphologically complex words,readers can choose to access the whole word meaning directly from the mental lexicon,or to use morphological rules to construct the word semantics.There is a general consensus that native speakers can access the whole word meaning by combing morphemes,however,despite increasing amount of second language research,the morphologically complex word processing mechanism for L2 learners is still in debate.Based on Complementary Learning Systems account and Episodic L2 Hypothesis,the processing mechanism of L2 morphologically complex words is proposed.Future research needs to explore the influences of morphological family size on the processing of L2 morphologically complex words,as well as reveal the neural mechanism underlying L2 morphologically complex words.
