Despite the vast literature that has implicated asymmetric activation of the prefrontal cortex in approach-withdrawal motivation and emotion, no published reports have directly explored the neural correlates of well-being. Eighty-four right-handed adults (ages 57-60) completed self-report measures of eudaimonic well-being, hedonic well-being, and positive affect prior to resting electroencephalography. As hypothesized, greater left than right superior frontal activation was associated with higher levels of both forms of well-being. Hemisphere-specific analyses documented the importance of goal-directed approach tendencies beyond those captured by approach-related positive affect for eudaimonic but not for hedonic well-being. Appropriately engaging sources of appetitive motivation, characteristic of higher left than right baseline levels of prefrontal activation, may encourage the experience of well-being.
尽管有大量文献表明前额叶皮层的不对称激活与趋近-回避动机及情绪有关，但尚无已发表的报告直接探讨幸福感的神经关联。84名右利手成年人（年龄在57 - 60岁之间）在静息脑电图检查前完成了关于心理幸福感、享乐幸福感和积极情绪的自我报告测量。正如所假设的那样，左侧额上回比右侧激活程度更高与两种幸福感水平的提高有关。半球特异性分析表明，目标导向的趋近倾向对于心理幸福感很重要，这种重要性超出了与趋近相关的积极情绪所体现的程度，但对于享乐幸福感则不然。适度激发食欲动机的来源，其特征是左侧前额叶激活基线水平高于右侧，可能会促进幸福感的体验。
