４０名正常被试在５场言语作业及２场非言语对照作业时记录ＥＥＧ，计算各场中１６个电极上δ，θ，α＿１，α＿２，β频带的功率值，并与静息睁、闭眼时相应的功率值比较，以了解大脑各区域的激活状况，结果表明不论言语或非言语作业均有大脑两半球的参预，言语作业时均为左半球激活占优势．本研究既支持汉语认知为左半球优势的观点，也证明汉字是两半球共同加工的“复脑文字”．
40 normal participants recorded EEG during 5 speech assignments and 2 nonverbal comparisons, and calculated the power values of δ, θ, α_1, α_2 and β bands of 16 electrodes in each field, Eye power corresponding to compare the value of the brain to understand the activation of the region, the results showed that regardless of speech or nonverbal homework both hemispheres in the speech, speech operations are dominant left hemisphere activation. This study not only supports the view that Chinese cognition is the predominance of the left hemisphere, but also proves that the Chinese character is “complex brain writing” co-processed by both hemispheres.
