摘要： 以10名年龄为19—24岁的男性大学生为被试进行了ERP实验。当被试对特定汉字的心理模板与实际呈现的汉字不匹配时,记录到一峰潜伏期在400ms左右的负走向波——N400。在形、义因素得到控制的条件下,汉字刺激和其心理模板间音因素的匹配与否影响到N400的左右不对称程度。N400和P300部分重叠,受到非语言因素如刺激字比例和判断任务的调制。

Abstract: 10 male university students aged 19-24 participated in the experiment.A negative-going ERP component N400 peaking around 410 ms appearedwhenever the mehtal template to a specific Chinese character mismatchedthe presented character. In conditions where graphemic and semantic fac-tors were constant the phonological match or mismatch affected the extentto which the N400 was asymmetrically distributed between the two hemis-pheres. The N400 was also found to be overlapped by P300 component asa result of the influences from such non-linguistic factors as the ratio ofdifferent types of characters and the tasks for judgement and response.
