ERP technique helps much in emotion studies. These studies usually recruited healthy people or individuals with mood disorders as research subjects. The variety of the ERP components,such as the P1, N1, and P300, elicited by visual and/or auditory stimuli were observed. This article reviewed and discussed some questions of ERP studies of emotion, such as the relationship between emotion and attention, memory and decision-making, and the lateralization of emotion, and so on. Research results suggest that emotion can enhance attention and novel emotional stimuli can be detected more easily. In normal subjects, emotional words can arouse stronger old-new effects than neutral words. Depressive patients cannot present the same effects as the normal ones, but their recognizing achievements can be improved by emotional words. When studying the influence of emotion upon decision-making, researchers observed changes of medial frontal negativity (MFN). The lateralization of brain functions also exists in emotional activities. |

ERP技术是研究情绪问题的有效手段,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,观察P1、N1和P300等ERP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,观察到内侧额叶负波(MFN).ERP研究表明,情绪活动也存在大脑功能的偏侧化效应. |
