| 摘 要： | 基于神经学方法的运用,情绪、情绪调节研究发现事件相关电位的晚正成分LPP与情绪刺激的自动化加工、有意控制加工之间有着紧密的联系。LPP源于枕叶和后顶叶皮层,由蓝斑——去甲肾上腺素系统对情绪刺激进行反应时产生,反映了注意对情绪刺激的持续偏向和加工。由于个体生活经历、年龄发展及基因的不同,LPP存在个体差异性。情绪调节的ERP研究发现,LPP的时程可作为情绪调节的替代指标。在此基础上,提出ERP在较完整理解情绪加工和调节这一应用领域中的未来发展方向。

| Abstract: | Based on the use of neuroseientific methods, researches on emotion and emotion regulation revealed that the late positive potential was closely linked with the automatic and controlled processing of emotional stimuli. The LPP is derived from the occipital and posterior parietal cortex, and generated via the locus coeruleus - norepinepherine system in response to emotional stimuli. The sustained increase in attention toward, and processing of, intrinsically motivating stim- uli can be tracked by LPP. Due to different life experience, age, and genes, there are individual differences in the LPP. Event - related potentials studies on emotion regulation have found that the time - course of the LPP can be utilized to in- dex emotion regulation. Based on previous studies, future directions for the application of ERP in achieving a more com- plete understanding of emotional processing and its regulation are presented. |
