摘要： 本实验利用汉字单词和图片为刺激材料,要求被试判断同时呈现在左视野和中央视野或右视野与中央视野的二个刺激是否属同一范畴,对范畴异同判断中大脑两半球功能不对称性进行研究。实验结果表明:(1)对汉字单词的处理为大脑左半球占优势,对图片材料的处理为大脑右半球占优势;(2)判断方式(异判断和同判断)在左半球和右半球之间未显示出不对称性。

Abstract: This experiment studies the laterality difference in the execution ofthe higher-order cognitive task categorization, utilizing Chinese wordsand pictures as stimuli materials. The subjects were called upon tojudge whether the two stimuli simultaneously presented in the right orleft visual field came under the same category. The results suggestedthat: (1) when using the nonverbal pictures as stimuli materials, thesuperiority of the right hemisphere in higher-order cognitive tasks wasevident, and when using the Chinese words as stimuli materials, thesuperiority of the left hemisphere in higher-order cognitive tasks wasevident; (2) the two hemispheres had no laterality difference in the"same" judgment and the "different" judgment modes.
