摘要
回顾了情绪场景性图片近几年的事件相关电位ERP研究结果,ERP成分的差异主要通过波幅和潜伏期表现出来,情绪图片刺激主要影响ERP成分的波幅,对峰值潜伏期的影响却不大.最近的研究成果表明,情绪场景性图片的唤醒度一般影响ERP波幅的晚期成分,图片的效价对ERP波幅以及峰值潜伏期的影响则因实验条件等因素的不同而发生变化.
The review summarized and integrated findings from recent years of event-related potential （ERP） stud-ies using pictures, the difference of ERP component consisted of two aspects： amplitude and latency. Affective stimulus factors primarily modulated ERP component amplitude, with little change in peak latency observed. The recent studies suggested that arousal of emotional scene picture influenced amplitude at longer latencies and va-lence＇ s influence on amplitude and peak latency varied with experimental conditions etc.
