采用Stroop按键实验范式，研究汉语词汇通达中语音的促进作用及音韵编码。实验一为单因素重复测量设计，探究与颜色字同音的拼音能否促进对相应颜色的判断，结果表明汉语词汇通达中语音有明显的促进作用。在验证了语音的促进作用的基础上，实验二研究汉语词汇通达中的音韵编码，以“红”字的读音为参照，设计2(拼音形式：音位、音节) ×2(同音音位位置：声母、韵母) ×2(拼音与其颜色对应的读音的关系：一致、不一致)三因素重复测量实验。结果发现：1、当呈现与颜色字读音相同的韵母时能够促进颜色判断；2、音位呈现条件下韵母同音的反应时显著短于声母同音的反应时，但在音节条件下两者没有显著差异。这表明汉字音韵编码的最小单位是音位，可能具有从左到右序列加工的特点。

The Stroop paradigm was applied to investigate the phonological facilitation effect and phonological coding in Chinese lexical access. Experiment 1 used a single factor repeated measurement design to test whether the Pinyin of Chinese color characters can facilitate the color identifying. The result showed that phonology plays an important role in Chinese lexical access. After confirmed the phonological facilitation effect, experiment 2 investigated phonological coding. With the Pinyin of ‘hong’ as reference, types of Pinyin (phoneme or syllable), position of the homophony phoneme (Shengmu or Yunmu) and consistency between Pinyin and color (consistent or inconsistent) were used in experiment 2. The results showed that (1) when the presented phoneme has same Yunmu from the font color of color word’s, subjects’ reaction time was significantly reduced; (2) when presented phoneme, the reaction time of homophonous Yunmu is shorter than homophonous Shengmu, but there is no significant difference between them when presented in the form of syllable. These indicated that phoneme is the least unit in Chinese phonological encoding and it’s probably that a serial process was involved during phonological encoding.
