| 摘 要： | 闪现刺激物诱发的视觉事件相关脑电位（ＥＲＰｓ）中，只有那些分布在较晚时域中的波，例如Ｐ３００、Ｎ４００等，内源性成分占优势，并与大脑的认知活动建立了较确切联系。本文报告一种模拟人类自然阅读时的事件相关脑电位（ＩＮＲ－ＥＲＰｓ），这种ＩＮＲ－ＥＲＰｓ的开矿学特征，不受注意的自动俘获效应的影响，不论是较晚还是较早时域中的波，都几乎是纯内源性的，并显示出了明显的心理学含义，我们还发现：对于同样的认知作业

| Abstract: | Among visual event related potential (ERP) waves elicited by flashstimuli,only those later ERP waves,such as the P300,N400,are predominately endogenous.They have been related to cognitive activities of the human brain.Here we report a novel type of visual event related potential measured during imitating natural reading (INR ERP).The morphological characteristics of the INR ERPs were free from the effect of automatically capturing attention.Both the later and the earlier INR ERP waves were purely endogenous and expressed obvious psychological implications.In addition,we also found some prominent earlier waves in purely endogenous INR ERPs These findings suggest the INR ERPs contain more information and may reflect complete cognitive processes more exactly. |
