汉字识别中形音义激活时间进程的研究（Ⅱ）

两个实验分别采用基于语义的和基于语音的启动范畴判断作业，在不同的SOA条件下，考察低频汉字形、音、义信息激活的相对时间进程。实验结果表明，低频汉字字形的激活在先，字音和字义的激活同时进行。低频汉字形、音、义激活的这种顺序不受基于语义还是基于语音的实验任务的影响，但实验任务影响了低频汉字字音、字义激活出现时间的早晚。

THE TIME COURSE OF GRAPHIC, PHONOLOGICAL AND SEMANTIC INFORMA TION PROCESSING IN CHINESE CHARACTER RECOGNITION (Ⅱ)

Using different tasks, the time course of graphic, phonological, semantic in formation activation during Chinese low frequency characters recognition was inv estigated in two priming-category judgement experiments based individually on th e semantic (Experiment 1) and phonological information (Experiment 2). In Exper iment 1, the graphic priming appeared at 43ms SOA, phonological and semantic pri ming appeared simultaneously at 85ms and 145msSOA. In Experiment 2, the graphic priming appeared at 43ms SOA, phonological and semantic priming appeared at 57ms , 85ms and145ms SOA. The two experiments showed: (1) for low frequency Chinese c haracters, graphic information was first activated; the phonological and semanti c activation could not separate obviously. (2) The order of the graphic, phonolo gical and semantic activation did not depend on the tasks that we had used.
