虽然情绪对身心健康有直接影响,但我们对情绪调节机制的了解有限。我在这里提出,在皮层激活联想和情绪调节之间存在着直接的、相互作用的关系,即积极的情绪促进联想加工,而联想加工促进积极的情绪。这种关系可能源于学习和预测的进化压力。按照这些思路,人们可以将情绪视为一种奖励机制,引导我们以最有成效的方式使用我们的大脑。建议的框架有许多含义,最显著的是诊断和治疗情绪障碍,如抑郁症,阐明抑制在情绪调节中的作用,成人海马神经发生的上下文,以及一般的、非侵入性的幸福感改善。
Although mood has a direct impact on mental and physical health, our understanding of the mechanisms underlying mood regulation is limited. I propose here that there is a direct, reciprocal relation between the cortical activation of associations and mood regulation, whereby positive mood promotes associative processing, and associative processing promotes positive mood. This relation might stem from an evolutionary pressure for learning and predicting. Along these lines, one can think of mood as a reward mechanism that guides us to use our brains in the most productive manner. The proposed framework has many implications, most notably for diagnosing and treating mood disorders such as depression, for elucidating the role of inhibition in the regulation of mood, for contextualizing adult hippocampal neurogenesis, and for a general, non-invasive improvement of well-being.
