本研究以成人及學童為對象進行兩個中文單字的唸字作業實驗，針對單字的字頻爲主要操弄的獨變項，探討在不同字頻下，字的音旁對唸字作業的效果。結果顯示音旁效果在高頻字情況下並不產生作用。澄清了Seidenberg的中文實驗予人產生的疑慮，並使得目前累積的中文字彙觸接研究結果增加 新的考慮方向。

n this study, the influences of character frequency and phonological information provided by a part of this character were investigated by a naming task, and we discussed lexical process in Chinese character naming. Experiment 1 modified Seidenberg's Chinese experiment and showed that phonological cue did not affect the error rates or reaction times of adult subjects' high frequency character naming, but did only have an effect on low frequency character naming. Therefore, it seems that phonology intervened, if any, the processing of characters only when they are of low frequency. It could be conceptualized that at least under high frequency condition characters were recognized on visual basis without phonological mediation. Experiment 2 showed similar results in children. Phonological encoding does not exist even in children who are learning Chinese. These results could not be explained by the traditional viewpoint that phonological encoding is necessary for lexical access.
