摘　　要：个体情绪加工具有其生物基础,也受到文化因素的影响。社会性和非社会性情绪刺激加工可能存在不同的机制。以往大多数研究主要关注负性情绪的加工差异。因此,本研究选取大学生被试20名并采用图片感知范式(picture perception paradigm)探讨个体在加工社会性和非社会性正性情绪刺激的脑电位活动差异。研究发现:(1)在P1成分上,情绪图片诱发的波幅要显著大于中性图片。(2)在N2成分上,正性社会情绪图片诱发的波幅要显著大于正性非社会情绪图片(3)在早期时间窗中,由正性社会情绪图片与非社会情绪图片诱发的LPP波幅差异不显著。在中期时间窗中,正性社会情绪图片与非社会情绪图片的LPP波幅差异显著。晚期时间窗中,正性社会情绪图片诱发的LPP波幅显著大于正性非社会情绪图片。由此,相对于非社会正性情绪刺激来说,正性社会情绪刺激在加工上可能占据优势地位。There were all sorts of different events which may arouse our emotional experiences in daily life. When processing and perceiving these emotional stimuli, we may experience different emotional reactivity. They could be influenced by biological factors as well as cultural factors. It had been recognized that emotions exist along a social/nonsocial emotional dimension. The sociality dimension may reflect the differences between basic biological drives （nonsocial） and complex social interaction （social）. Even though previous studies examined the important differences in social and non-social emotional stimuli, most of them focused on the negative emotions. However, as an important and indispensable part of the field of emotion study, it is necessary to include the study of positive emotions. Positive emotions are considered to be adaptive experiences and helpful to promote individual＇s psychological well-being. In the current study, we aimed to examine the differences of the emotional reactivity with regard to processing social/nonsocial positive emotions. Emotion perception is a process that integrates physiological, cognitive, and behavioral components. A series of event-related brain potential （ERP） studies have been reviewed to demonstrate the consistent and robust modulation of specific ERP components by emotional images. Specifically, emotional, compared with neural, pictures elicit an increase in the early ERP components （e.g., P1, P2, and N2） and the late positive potential （LPP）. Modulations of the ERP components are thought to reflect the facilitated processing of, and increased attention to, motivationally salient stimuli. Therefore, ERPs provide a powerful measurement tool for capturing neural activity related to emotional responding. In the present ERP study, we used the Picture Perception Paradigm to explore the differences in the brain cortical reactivity to social/nonsocial positive emotions. When 20 undergraduates watched and evaluated these social, neutral, and nonsocial pi
