This paper aims to examine a hypothesis that phonological processing should occur in Japanese Kanji words as well as in Kana words, but automatic in Kanji words. In Experiment 1, subjects performed concurrent articulation or finger tapping during a semantic processing task of Kana words with 2 to 4 phonemes, for which phonological processing should be indispensable. Concurrent articulation was found to eliminate the phoneme number effect found in the control condition, but finger tapping was not. This result indicates the effectiveness of concurrent articulation in articulatory suppression. In Experiment 2, the materials were changed to Kanji words, for which phonological processing had been supposed to be dispensable, and subjects performed the same task. The results showed no phoneme number effect even in the control condition, and the reaction time in the concurrent articulation condition was delayed significantly. These results suggest the existence of automatic phonological processing of Kanji words. Finally, the pertinence of this hypothesis was confirmed by applying it to the explanations of 3 kinds of Japanese dyslexia.
本文旨在检验一个假设，即语音处理不仅会出现在日语假名单词中，也会出现在汉字单词中，但在汉字单词中是自动进行的。在实验1中，受试者在对包含2至4个音素的假名单词进行语义处理任务时，同时进行发音或手指敲击，对于这些假名单词而言，语音处理应该是必不可少的。结果发现，同时发音消除了在控制条件下发现的音素数量效应，但手指敲击则没有。这一结果表明了同时发音在发音抑制方面的有效性。在实验2中，材料换成了汉字单词，之前认为对汉字单词而言语音处理是不必要的，受试者执行相同的任务。结果显示，即使在控制条件下也没有音素数量效应，并且在同时发音条件下的反应时间显著延迟。这些结果表明汉字单词存在自动语音处理。最后，通过将该假设应用于对三种日语阅读障碍的解释，证实了该假设的相关性。
