This article presents an overview of the author's recent electrophysiological studies of anterior cerebral asymmetries related to emotion and affective style. A theoretical account is provided of the role of the two hemispheres in emotional processing. This account assigns a major role in approach- and withdrawal-related behavior to the left and right frontal and anterior temporal regions of two hemispheres, respectively. Individual differences in approach- and withdrawal-related emotional reactivity and temperament are associated with stable differences in baseline measures of activation asymmetry in these anterior regions. Phasic state changes in emotion result in shifts in anterior activation asymmetry which are superimposed upon these stable baseline differences. Future directions for research in this area are discussed.
本文概述了作者最近关于与情绪和情感风格相关的大脑前侧不对称性的电生理研究。文中提供了一个关于两个半球在情绪处理中作用的理论阐释。该阐释分别将两个半球的左、右额叶及前颞叶区域在与趋近和退缩相关行为中赋予了主要作用。与趋近和退缩相关的情绪反应性及气质方面的个体差异，与这些前侧区域激活不对称性的基线测量中的稳定差异相关。情绪的阶段性状态变化会导致前侧激活不对称性的改变，这些改变叠加在这些稳定的基线差异之上。本文还讨论了该领域未来的研究方向。
