主题信息合理性、语境意义偏向性对汉语歧义句意义建构的影响

两个实验以合理型主题信息条件下的句子为对照材料．其它型主题信息条件下的句子为实验材料，考察合理型和非合理型主题信息条件下汉语歧义句意义建构的时间进程和特点。结果表明：(1)合理型主题信息可以顺利地建构一个稳定的基础心理表征；不合理型主题信息则没有这种效应；矛盾型主题信息则引导读者重构一个新的心理表征。(2)在合理型主题信息条件下，语境主要起到证实主题信息区和歧义区所建构的基础表征的作用；而在不合理型、矛盾型主题信息的条件下，语境的作用首先是验证所建构的基础心理表征和歧义句的意义频率，然后有效建构歧义句的意义。

The Effect of Thematic Information,Context Meaning Frequency on Resolving the Ambiguity Sentences in Chinese

Two experiments were conducted to investigate how ambiguity sentences constructed their mental representation and structure in Chinese. The result showed the reasonable thematic information could construct a stable basic mental representation while unreasonable thematic information could not. Contradictory thematic information caused readers to reconstruct a new mental representation. Under the condition of reasonable thematic information, context mainly served to verify the meaning frequency of ambiguous sentences, but under the condition of unreasonable and contradictory thematic information, context first served to testify the basic mental representation and the meaning frequency of ambiguous sentences, then to resolve ambiguous sentences.
