双语心理词典的语义表征研究

A Study on Semantic Representations in Bilingual Mental Lexicon

本文从英汉双语心理词典的数量和第二语言词汇习得与双语心理词典研究的最新成果出发,论述了英汉心理词典中的语义表征。首先,在讨论有关专家学者对心理词典表征结构描述的基础上,分析了英汉双语者大脑中词典的数量问题,认为这一问题其实就是双语心理词典中的语义表征问题,存在两部词典就是语义独立表征,存在一部词典就是语义同一表征;其次,对双语心理词典进行的描述是对一个二语单词在被双语者习得过程中的不同阶段语义表征的描述,是学习者对不同熟悉程度的二语单词语义表征的分析。以从动态的、发展的观点来研究英汉双语心理词典,有利于我们更加清晰、全面地了解英汉双语心理词典的语义表征。

This paper mainly makes a further study on semantic representations in English-Chinese mental lexicon from the aspects of the number of mental lexicons in a bilingual＇s mind and the new trends of second language vocabulary acquisition and bilingual mental lexicon.It begins with the question of the number of mental lexicon in a bilingual＇s mind and regards it as that of lexical semantic representations in bilingual mental lexicon,one mental lexicon being shared semantic representation while two mental lexicons being independent semantic representation.It argues that this static and isolated view of semantic representations is not complete,and then a dynamic and developmental view of semantic representations from the new trends of second language vocabulary acquisition and bilingual mental lexicon is discussed.Finally it points out that the description of mental lexicon is in essence the description of the semantic representations of an L2 word at different developmental stages and different familiarity levels.
