The neural correlates underlying the regulation of anticipation on regret.

Regret is a common negative emotion in daily life, and long-term immersion in regret affects mental health. Therefore, to regulate and reduce regret is of wide concern. The current fMRI study aimed to investigate whether outcome anticipation before decision-making could reduce regret and its neural correlates. In the task, participants were asked to anticipate the possible poor outcomes of subsequent decisions, such as missing rewards and meeting punishment, and then made sequential risk-taking decisions. Behavioral results showed that outcome anticipation before decision-making could decrease the intensity of regret, that is, participants felt less regret when they anticipated the outcome before decision-making (anticipation condition, Ant), compared to making sequential risk-taking decisions without any anticipation of the outcome in advance (non-anticipation condition, NAnt). Consistently, at the neural level, stronger activities of ventral striatum (VS) and dorsal medial prefrontal cortex (dmPFC), and greater VS-dmPFC functional connectivity were observed in Ant relative to NAnt. Moreover, the activity of dmPFC was negatively correlated with the intensity of regret in Ant. The current study highlighted that outcome anticipation before decision-making could regulate regret effectively, and dmPFC played a vital role in this process.
