实验任务对汉语同形歧义词加工过程的影响

The Processing of Chinese Homographs in Different Tasks

两个实验采用不同的实验任务,探讨句子语境中同形歧义词(homographs)歧义消解的过程以及激活和抑制机制的作用。结果表明:(1)采用词汇判断任务时,与语境一致的同形歧义词的主要意义首先得到通达,与语境一致的次要意义随后才被激活;(2)采用意义适合性判断任务时,同形歧义词不适当的意义受到了不同程度的抑制;(3)相对意义频率对同形歧义词歧义消解过程有影响。

Two experiments were conducted to investigate the processes of meaning access and the effect of inhibition of homographs in Chinese. The results showed: (1) in the200 msec SOA condition, the homographs' dominant meanings which were consistent with context semantics were activated first. In the 400 msec SOA condition, homographs' subordinate meanings which were consistent with context semantics were activated then. (2) The subordinate (inappropriate) meanings of homographs can be inhibited, but the dominant (inappropriate) meanings of homographs cannot be inhibited completely. (3) In two experiments, the processing of homographs was influenced by meaning frequency.
