低频汉字识别中语音与字形的作用机制研究——基于听障大学生与健听大学生的比较

On the Mechanism of Phonological Coding and Graphic Coding in Low-Frequency Chinese Character Recognition——Based on the Comparison Between Hearing-Impaired and Normal-Hearing College Students

研究采用语义一致性判断任务方法,通过操纵干扰项和目标项在语音和字形上的相似性、改变刺激呈现进程并比较听障大学生与健听大学生的反应特征,探讨低频汉字识别中语音、字形的作用机制。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与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激活产生影响。在此基础上,研究探讨了发音核证检验与书写核证检验的文字学基础。

Using the homo-semantic judgement task,the role of phonological coding and graphic coding can be explored systematically by manipulating the visual or phonetic similarity of distracter(character） and targets(picture）,varying stimulus onset asynchorony,and comparing the reaction characteristics between hearing-impaired college students and hearing control group. The results showed that phonological code and graphic code were activated in early stage,and respectively acted as pronouncing check and spelling check to minimize the interferences from visual similarity and phonetic similarity during low-frequency Chinese character recognition. The philological foundation of pronouncing check and spelling check was also investigated and discussed. Besides,consistency affected the activation of phonological code in low-frequency Chinese character recognition.
