汉语同音歧义词歧义消解的过程及其抑制机制

THE INHIBITION MECHANISM FOR RESOLVING LEXICAL AMBIGUITY OF TWO-SYLLABE HOMOPHONES IN CHINESE

两个实验分别采用词语境或句子语境探讨汉语同音歧义词 (homophones)歧义消解的过程。被试为 112名大学生。实验通过有计划地比较不同语境偏向条件下有关探测词和无关探测词之间反应时的差异 ,从而揭示汉语同音歧义词消解过程中 ,对其适当意义激活以及对其不适当意义抑制的时间进程。两个实验的结果都表明 :在同音歧义词加工的早期 ,语境的作用主要表现为抑制歧义词不适当意义 ,阻止其激活 ;随后 ,语境促进了歧义词适当意义的激活。另外 ,相对意义频率在同音歧义词歧义消解过程中有其影响。

Two experiments were conducted to investigate the processes of meaning access and the effect of inhibition of two-syllable homophones in Chinese. Cross-model semantic priming paradigm and lexical decision task were employed in the experiments. The homophones were presented after a word which was used as context in Experiment 1 and in sentences in Experiment 2. The results showed: First, in the -150ms ISI condition, the homophones' inappropriate meanings which were inconsistent with context semantics were inhibited. Second, in the 50ms condition, priming effects were found for the homophones' appropriate meanings which were consistent with context semantics. Third, the processes of meaning access of homophones was influenced by meaning frequency.
