心理词典研究是心理语言学、神经语言学、理论语言学共同关注的一个焦点问题,是当代人类认知研究的一个重要方面。心理语言学家把词在长时记忆中的表征称为我们的内部词典,这种心理表征包括词的发音知识、词形知识和词义知识。激活心理词汇意义的过程叫做词汇通达,它受到词频、词汇歧义性、语素结构、语境及语义启动等因素的影响。这些因素的相互作用影响着词汇的掌握和应用。 Psychological dictionary research is a focus issue of psycholinguistics, neurolinguistics and theoretical linguistics. It is an important aspect of contemporary human cognition research. Psycholinguists refer to the representation of words in long-term memory as our internal dictionary, which includes the pronunciation, vocabulary and word-sense of words. The process of activating mental lexical meaning is called lexical accessibility, which is affected by factors such as word frequency, ambiguity of lexis, morpheme structure, context and semantic activation. The interaction of these factors affects the mastery and application of vocabulary.
