We review conceptual arguments and research on the role of asymmetric frontal cortical activity in emotional and motivational processes. The current article organizes and reviews research on asymmetrical frontal cortical activity by focusing on research that has measured trait (baseline) frontal asymmetry and related it to other individual differences measures related to motivation (e.g., anger, bipolar disorder). The review also covers research that has measured state frontal asymmetry in response to situational manipulations of motivation and emotion and as an intervening variable in motivation-cognition interactions. This review concludes that much research supports the view that greater left than right frontal cortical activity is associated with greater positively or negatively valenced approach motivation. The view that greater right than left frontal cortical activity is associated with withdrawal motivation, although supported, has received less empirical attention. In addition to reviewing research on the emotive functions of asymmetric frontal cortical activity, the reviewed research illustrates the need to consider motivational direction as separate from affective valence in conceptual models of emotional space.
我们回顾了关于不对称额皮质活动在情感和动机过程中作用的概念性争论和研究。本文通过关注测量特质（基线）额不对称性并将其与其他与动机相关的个体差异测量（例如，愤怒，双相情感障碍）的研究，组织并回顾了额不对称性的研究。该综述还涵盖了研究，这些研究测量了对动机和情绪的情境操作的状态额不对称性，以及作为动机-认知相互作用的中介变量。该综述的结论是，许多研究支持这样一种观点，即左侧额皮质活动大于右侧与更大的正或负趋近动机有关。尽管支持更大的右侧额皮质活动与退缩动机有关的观点，但它得到的实证关注较少。除了回顾不对称额皮质活动的情感功能研究外，所回顾的研究还说明了在情感空间的概念模型中，需要将动机方向与情感效价分开考虑。
