摘要/Abstract

摘要： 内源性注意和外源性注意反映注意指向与集中的自上而下和自下而上的加工。大量事件相关电位的ERP研究考察了内源性注意和外源性注意的神经活动机制。内源性注意诱发了早期N1成分和晚期P300成分，是否诱发P1成分的研究结果不尽一致；外源性注意加强了N1成分、P1成分以及P300成分。研究还表明内源性注意和外源性注意是两种独立的注意系统，以不同的方式影响着脑内的信息加工

关键词: 内源性注意, 外源性注意, ERP成分

Abstract: Endogenous attention and exogenous attention reflect the top-down and bottom-up regulation mechanism of orientation and focus of attention. Great deal of event-related potentials studies investigated the effect of endogenous and exogenous attention on neural activities. Endogenous attention has been shown to enhance as early as N1component and late P300 component, while whether early P1 component can be enhanced was less consistent; exogenous attention has been found to enhance N1component, P1 component, and late P300 component. It has also been found that endogenous and exogenous mechanisms represent two attention systems that can affect information processing in the brain in distinct ways

Key words: endogenous attention, exogenous attention, ERP studies
