摘要： 本研究用音同或形似汉字词对为材料检验大脑半球偏侧化问题。反应时的结果表明音同材料是右视野左半球优势,形似材料是左视野右半球优势。ERP的振幅(特别是P_(300))在音同条件下左半球比右半球显著的小,而在形似材料条件下左右半球无大差别。在两种材料的条件下,ERP潜伏期在左右半球之间也没有显出任何差别。实验结果表明左半球与汉字词匹配时的语音编码有关,而ERP(P_(300))似乎可以做它的一个有效指标。

Abstract: The laterality of hemispheric function was tested by using Chinesecharacters which were two sets of word pairs that had same phoneme orlooked alike. The reaction time of the right field-left hemisphere wassuperior for the word pairs of the same phoneme but the left field-righthemisphere was superior for the looking alike. word pairs The ERPamplitude, especially P300, was significant smaller for left hemispherecomparring to right hemisphere under same phoneme condition. TheERP had no clear difference between left and right hemisphere for thewords pairs that looked alike. The latency of ERP also had no differen-ce between the left and right hemispheres under the two kinds of materialconditions. The results indicate that the left hemisphere relates to phone-mic coding of Chinese words and ERP (P300) seems to be its effectiveindex.
