人名相关自我加工的时间过程——事件相关电位研究提供的电生理证据

本研究采用事件相关电位技术（ERP）探讨了自我名字加工的神经机制。实验中向被试随机呈现大圆、小圆及名字，被试的任务是辨别大圆和小圆，名字是任务无关刺激。实验结果表明，被试自己的名字引发的P2及P3波幅都显著高于名人的名字及陌生人的名字。 与以往研究结果不同，本研究发现了P2波幅上的“自我名字效应”，即，人名相关的自我加工不仅表现在晚期成分P3上，同时还表现在早期成分P2上。所以，人名相关的自我加工过程分为早期和晚期两个加工阶段，前一个阶段可能是自动化加工，不需要意识参与，后一个阶段是意识加工。

The Time Course of Self-processing Involved in the Detection of One's Own Name:Electrophysiolgical Evidence From ERP

All previous ERP studies on cerebral mechanisms underlying the detection of our ows names used auditory materials,and some of these studies have problems in the experimental design.So the present study has three purposes:Firstly,to explore the cerebral mechanisms underlying the detection of one's own name in the visual channel.Secondly,to make the experimental design closely resemble natural situations.In the present study the subjects performed a big/small circle discrimination task and the names were task...
