情绪场景性图片ERP研究成果综述

ERP Achievements of Emotional Scene Picture

情绪场景性图片加工阶段的ERP波幅变化受图片效价和唤醒度的影响。情绪场景性图片的唤醒度效应一般出现在晚期,效价效应的潜伏期范围因实验条件因素的不同而变化,一些情绪ERP调节随记录方法、刺激因素、任务以及情绪状态而发生变化。

The valence and arousal of scene pictures influences amplitude of ERP when they are processed.Arousal effects are consistently obtained,and generally occur at longer latencies,while valence effects vary with experiment condition etc.Some affective ERP modulations vary with recording methodology,stimulus factors,as well as task-relevance and emotional state.
