The current study investigates how long-term Tai Chi experience affects the neural and emotional response to regret in elders. Participants perform the sequential risk-taking task while undergoing functional magnetic resonance imaging (fMRI) scanning. In the task, participants opened a series of boxes consecutively and decided when to stop. Each box contained a reward, except for one which contained a devil. If the devil was revealed, then this served to zero the participant's gain in that trial. Once stopped, participant's gains and missed chances were revealed. Behaviorally, the Tai Chi group showed less regret, reduced risk taking, higher levels of nonjudgment of inner experience and less emotional sensitivity to outcome. fMRI results showed that the Tai Chi group demonstrated stronger fronto-striatal functional connectivity in trials with numerous missed chances. The nonjudgment of inner experience mediated the impact of fronto-striatal functional connectivity on Tai Chi practitioners' emotional sensitivity to outcome. These results highlight that long-term Tai Chi exercise may be effective in alleviating feelings of regret in elders by promoting reduced judgment of inner experience and enhanced emotion regulation through the strengthening of fronto-striatal functional connectivity.
本研究旨在探讨长期习练太极拳对老年人在面对遗憾时的神经和情绪反应的影响。参与者在进行功能磁共振成像（fMRI）扫描的同时完成序贯风险任务。在任务中，参与者依次打开一系列盒子并决定何时停止。每个盒子都包含奖励，除了一个盒子里面有恶魔。如果揭示出恶魔，那么该轮参与者的收益就会清零。一旦停止，参与者的收益和错过的机会就会被揭示。行为上，太极拳组表现出较少的遗憾、降低的风险承担、更高的内在体验非评判性和对结果的较低情绪敏感性。fMRI 结果表明，在错过机会较多的试验中，太极拳组表现出更强的额-纹状体功能连接。内在体验的非评判性中介了额-纹状体功能连接对太极拳习练者对结果的情绪敏感性的影响。这些结果表明，长期习练太极拳可能通过增强额-纹状体功能连接，促进内在体验的减少判断和增强情绪调节，从而有效缓解老年人的遗憾感。
