词语境中汉语歧义词多个意义的加工过程

两个实验利用词语境,分别探讨汉语同形歧义词(homographs)和同音歧义词(homophones)多个意义的加工过程。实验采用词汇判断任务,被试为128名中国农业大学和北京科技大学的大学生。实验结果表明:(1)语境词可以提高汉语同形歧义词与语境一致的次要意义的激活水平。(2)在汉语同音歧义词多个意义的加工过程中,语境词既可以抑制同音歧义词的不适当意义,即阻止其激活;也可以促进同音歧义词适当意义的激活。(3)歧义词相对意义频率对汉语同形歧义词和同音歧义词多个意义的加工过程有影响。

The Semantic Processing of Chinese Ambiguous Words in Word-context

Two experiments were conducted to explore the processing of Chinese homographs and homophones in word-context.Subjects were 128 students(Exp1 and 2) in Beijing University of Science and Technology,and Beijing Agriculture University,China.They were asked to verify whether the probe is a word or not.The probes were present at stimulus onset asynchronism(SOA) 250ms and 500ms(Exp1),or were presented at interstimulus interval(ISI)-150ms and 50ms(Exp2) respectively.The results showed:(1) The activation of homographs' subordinate meanings which were consist with context semantics can be improved by word-context.(2) In the-150ms ISI condition,the homophones' inappropriate meanings which were inconsistent with context semantics were inhibited.But,in the 50ms condition,priming effects were found in homophones' appropriate meanings which were consistent with context semantics.(3) The processes of homographs and homophones were influenced by meaning frequency.
