４０名正常被试在４场言语作业及２场非言语作业时记录脑电图，计算各场中１６个电极上δ、θ、αｌ、α２及β频带的功率值，与安静睁、闭眼时相应的功率值比较，以了解大脑各区的激活状况。结果表明言语或非言语作业均有大脑两半球的参与，言语作业时为左半球激活占优势，非言语视觉空间作业为右半球占优势。本研究支持汉字认知的左半球优势观点，也表明汉语认知是由左及右半球共同加工的。 40 normal subjects recorded EEG in 4 speech assignments and 2 nonverbal assignments, and calculated the power values ​​of δ, θ, α1, α2 and β in 16 fields in each field, When the corresponding power comparison, in order to understand the brain activation of the district. The results showed that either speech or non-verbal assignments both involved the hemispheres of the brain, the left hemisphere was predominantly active during verbal assignments, and the non-verbal visual space was dominated by the right hemisphere. This study supports the dominant left-hemisphere perspective of Chinese cognition and also indicates that Chinese cognition is processed by left and right hemispheres.
