情绪调节策略可以改变对情绪刺激的行为和生理反应，以及这些反应在杏仁核或纹状体等区域的神经相关性。目前的研究调查了在财务决策中使用情绪调节技术时的大脑系统。在决策过程中，通过以重新评估为中心的策略来调节情绪，鼓励采取不同的观点，已经被证明可以减少损失厌恶，这在选择和对实际损失和收益结果的相对唤醒反应中都可以观察到。在目前的研究中，我们发现，使用功能磁共振成像的行为损失厌恶与杏仁核活动的反应损失相对于收益。成功地调节损失厌恶也与杏仁核对损失的反应减少有关，但与收益无关。此外，在决策和结果中，我们发现重新评价策略增加了背外侧和腹内侧前额叶皮层和纹状体的基线活动。尽管任务不同，但观察到的神经回路与情绪调节的神经回路相似，这进一步证明了情绪在决策中的作用，以及重新评价改变价值评估和选择的力量。
Emotion regulation strategies can alter behavioral and physiological responses to emotional stimuli and the neural correlates of those responses in regions such as the amygdala or striatum. The current study investigates the brain systems engaged when using an emotion regulation technique during financial decisions. In decision making, regulating emotion with reappraisal-focused strategies that encourage taking a different perspective has been shown to reduce loss aversion as observed both in choices and in the relative arousal responses to actual loss and gain outcomes. In the current study, we find using fMRI that behavioral loss aversion correlates with amygdala activity in response to losses relative to gains. Success in regulating loss aversion also correlates with the reduction in amygdala responses to losses but not to gains. Furthermore, across both decisions and outcomes, we find the reappraisal strategy increases baseline activity in dorsolateral and ventromedial prefrontal cortex and the striatum. The similarity of the neural circuitry observed to that seen in emotion regulation, despite divergent tasks, serves as further evidence for a role of emotion in decision making, and for the power of reappraisal to change assessments of value and thereby choices.
