语音与字形在高频汉字识别中的作用——基于听障大学生与健听大学生的比较研究

On the Roles of Phonological Codes and Graphic Codes in HighFrequency Chinese Character Recognition——Based on the Comparison Between Hearing-Impaired and Normal-Hearing College Students

本研究采用语义一致性判断任务,通过操纵干扰项和目标项在字形和语音上的相似性、改变刺激呈现进程、以及比较听障大学生与健听大学生的反应特征探讨语音、字形在高频汉字识别中的作用。研究发现,语音、字形均在汉字识别的早期阶段激活,并分别通过发音核证检验、书写核证检验起到减少汉字形似性、同音性对汉字识别干扰的作用。同时,一致性对汉字识别中语音的激活产生影响。

This study, based on the homo-semantic judgment task, the manipulation of the graphic or phono- logical similarities of distracters （Chinese characters） and targets （pictures）, the variation of stimulus onset asynchorony （SOA）, and the comparison of the reactions between hearing-impaired college students and hearing-normal college students, aims to probe into the roles of phonological codes and graphic codes in high-frequency Chinese character recognition. The results indicated that phonological codes and graphic codes were both activated in the early stage of Chinese character recognition, and could, by checking pro nunciations and writing, respectively help minimize the interferences from graphic and phonological similarities during Chinese character recognition, and that consistency affected the activation of phonological codes in Chinese character recognition.
