Chinese characters are mostly constructed of a part with phonological information and a part with meaning(radical). Because of this difference with alphabetic system, word recognition has been always a popular topic in psychology, especially the role of phonological representations and orthographic representations in Chinese characters recognition. Many studies have found the importance and necessity of phonological representations in lexical access of Chinese characters. Some studies have found that orthographic representations play some role in lexical access of Chinese characters. There seems to be two routs of processing Chinese characters. These two routs appear to match the process of verbal and visual working memory proposed by Baddeley(1986).In this study, we want to explore this relationship.
There are three experiments in this study. We designed phonological and visual concurrent tasks intervene the processing of Chinese characters and saw if these tasks influence the performance of Chinese character recognition. In experiment 1, We presented six characters successively with each 230 ms. After that subjects performed an intervention judgment task , then character recognition. We found there was a significant advantage of phonological representations in high frequency characters, but no difference between phonological and orthographic representations in low frequency. In experiment 2, after we shortened the presentation time, number of Chinese characters, switched characters recognition and intervention task and changed the stimulus material to extremely unfamiliar characters in low frequency characters, the difference between phonological and orthographic representations is not significant. In experiment 3, maintaining the condition as in experiment 2, we prolonged the presentation time and found that when phonological loading was heavy, subjects preferred visual cue and when visual loading was heavy, they preferred phonological cue.
It shows in this study that, phonological information plays an important role in Chinese character recognition, just as in alphabetic system. Only when phonological loading is too heavy, orthographic information will be used.
