摘要： 技术是研究情绪问题的有力手段。实验对象包括正常被试以及心境障碍的病人。可从视觉或/和听觉通道给予情绪刺激材料，观测N2、P3和N400等成分的变化。研究发现，情绪可增强被试对情绪事件的注意强度，尤其是新异的情绪内容较易得到识别。在正常被试中，情绪词相较中性词能引起较大的新旧效应，抑郁症患者的新旧效应与正常人有所不同，但其再认成绩也能被情绪内容提高。在研究情绪对决策行为的影响时，观测到内侧额叶负波（MFN）。ERP研究表明，情绪活动也存在大脑功能偏侧化问题。

Abstract: ERP technique helps much in researches of emotion. Normal people and patients with mode disorders can be recruited as subjects in these studies. Experimenters give stimuli through visual and/or auditory modality, then observe the varieties of components, such as N2, P3 and N400, etc. Studying results suggest that emotion can enhance attention intensity and novel emotional stimuli can be detected more easily. In normal subjects, emotional words can arouse bigger old-new effects than neutral words. Depressive patients can not present the same effects as the normal, but their recognizing achievements can be improved by emotional words. When studying the influence of emotion toward decision-making, researchers observed changes of medial frontal negativity (MFN). Lateralization of brain functions also exists in emotional activities.

Key words: emotion, mood disorder, ERP
