Two naming experiments are conducted to investigate the effects of phonetic radicals and pattern of stroke removal on identification of Chinese phonogram. A 2×3 within-participants design was used to examine left-right structure phonograms in Experiment 1. One independent variable was the position of phonetic radicals (left side and right side), and the other was the pattern of stroke removal (beginning stroke removal, ending stroke removal, normal character). The analyses were based on measures of reaction time and accuracy rate. The results show that (1) Significant difference was found among the stroke removal patterns(p＜.001). Reading normal characters is easiest, whilst characters with beginning strokes removed were most difficult to name. (2) Significant difference of the position of phonetic radicals was also obtained(p＜.001). The character with phonetic radical on the left side had shorter reaction time and higher accuracy rate than that on the right side. (3)There was a significant interaction between the two factors(p＜.001). When the phonetic radical was on the right side of the character, the result was reversed: the reaction time of the characters with ending strokes removed was longer and the accuracy rate was lower. It indicates that if the ending strokes removed is the phonetic radical, the stroke removal effect will disappear, which reflects the important role of phonetic radicals on identification of Chinese phonograms. To verify the universality of the result in Experiment 1, Experiment 2 examines the identification of Chinese up-down structure phonograms and also the 2×3 within-participants design was used. The result of Experiment 2 is similar to that of Experiment 1, and the tendency was more obvious. Experiment 2 shows that (1) Significant difference of stroke removal pattern was also observed like Experiment 1(p＜.001). (2)There was no significant difference of the position of phonetic radicals(p＞.05). (3) There was also significant interaction between the two factors(p＜.001). The effect was the same as the Experiment 1 and is stronger than that. The results in both Experiment 1 and Experiment 2 verify the stroke removal effect which is consistent with the results of the prior studies. More importantly, the present study indicates that phonetic radicals play an important role in identification of Chinese phonograms. According to the dual route model, there exists a phonetic activation on identification of Chinese phonograms.
