汉语句子阅读理解中的语境效应

采用计算机快速系列视觉呈现技术，以反应时为指标，利用命名法，考察了汉语句子阅读中的语境效应。该研究表明：语境的作用机制是灵活的，它会随语境条件的变化而变化。在启动词与目标词语义联结弱的情况下，如果语境对目标词是一种低干扰，那么各模块之间彼此独立，一个模块不受另一个模块的影响；如果句法关系改变后的语境对目标词形成高干扰，各模块相互作用，不同语境对词汇通达有不同的作用。当启动词与目标词间有较强的语义联结时，语境效应主要来源于词与词之间的联结启动，这时的语境作用机制符合模块化理论；而当启动词与目标词间有较弱的语义联结时，随语境干扰强度的增加，目标词的词汇通达也随之增加，这时的语境作用机制则符合相互作用理论。

CONTEXT EFFECTS IN CHINESE SENTENCE READING COMPREHENSION

The context effects in Chinese sentence reading comprehension was studied. The naming task was used via rapid serial visual representation with reaction time as index. The results indicated that the acting mechanism of context changes under different contextual conditions. With weak semantic association between the prime word and the target word,on the one hand, the modularities are independent of one another in the context which is lowly incongruent with the target word, i.e. the modularities are not influenced by other ones; on the other hand, the modularities are interactive when the context is highly incongruent with the target word, i.e. different contexts have different effects on lexical identification. With strong semantic association between the priming word and the target word, the context effect results from the associative priming, which proves the modularity theory.
