摘　　要：采用社会问题情境,通过记录38名高、低特质社会创造性被试在社会问题解决过程中的脑电活动,考查不同特质社会创造性的被试在表现不同状态社会创造性时的脑电激活模式。结果表明:无论高频还是低频α波同步化都存在状态创造性的主效应。同时,高、低频段的α波同步化还存在特质创造性与状态创造性之间显著的交互作用,在表现高状态社会创造性时,高特质的被试比低特质的被试出现更高的α波同步化水平。此外,对于高频α波同步化,状态创造性、特质创造性以及大脑半球的三重交互作用达到显著性水平,低特质社会创造性的被试在表现高状态社会创造性时,右脑半球比左脑半球出现更强烈的α波同步化,在其他情况下均无显著差异。未来的研究可以采用时间进程分析、纵向研究设计、脑功能成像技术探查社会创造性的脑机制。Creativity is commonly defined as the ability to simultaneously produce novel （original, unique） and useful work within a social context. Social creativity, as a new domain of creativity, is observed when one proposes and solves social problem in the original, appropriate and effective ways. Creativity can be studied from the perspective of state and trait, as many psychologists have studied the psychological variables such as anxiety and self-esteem. With the fast development of neuroscience, research on the brain mechanism of creativity has recently attracted great attention in psychology. Most EEG studies about creativity focused on the alpha activity in the process of creative idea generation. In current study we examined brain mechanisms of social creativity from the perspective of state and trait by recording the EEG of 38 college participants in the social problem scene. We measured participants’ state social creativity using the Questionnaire of Social Creativity for College Students and their trait social creativity using open-ended questionnaire of social problems. The repeated measures ANOVA design in the lower and upper alpha frequency band was used, with state social creativity （high vs. low）, hemisphere （left vs. right）, and area （prefrontal, frontal, central, parietal, temporal, occipital） as the within-subject factors, and with trait social creativity （high vs. low） as between-subject factor. We found the alpha synchronization in the process of creative social problem solving. A significant main effect of state social creativity was observed on the upper alpha band and the lower alpha band, suggesting that high state social creativity showed a lower alpha synchronization as compared with the low state social creativity. The main effect of hemisphere, area, and the level of trait social creativity failed to reach statistical significance. Moreover, there was the interaction of trait creativity with state creativity, and when presenting high state social creativity, individuals
