摘要
在模拟人类自然阅读的方式下，研究了大脑对字符的细微结构进行选择性注意作业时的事件相关脑电位，获得了分布在Ｎ１位置及附近时域的与大脑认知过程直接相关的较早内源性成分，对Ｐ３００的心理学含义有了进一步的了解．
In this paper,event related potentials to fine structure of the pictographic characters during emulating true reading in a paradigm of selective attention task were investigated.The early endogenous components that were directly related to the brains cognition process and appeared in the time range of N 1 and N 1 nearby were observed.The clear and unambiguous phychology meaning of P 300 was obtained.
