Abstract

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.

长期有太极拳经验的老年人减少后悔感并增强额纹连接

摘要

当前的研究调查了长期太极拳体验如何影响老年人对后悔的神经和情绪反应。参与者在进行功能性磁共振成像（fMRI）扫描的同时执行顺序冒险任务。在任务中，参与者连续打开了一系列盒子，并决定何时停止。每个盒子都包含奖励，除了一个盒子里装有魔鬼。如果发现了魔鬼，那么这会使参与者在该审判中的收益为零。一旦停止，参与者的收获和错过的机会就会显现出来。在行为上，太极拳组表现出较少的后悔，减少的冒险，对内在经验的不判断水平较高以及对结局的情感敏感性较低。功能磁共振成像结果显示，太极拳组在试验中表现出更强的额纹体功能连接性，错失了很多机会。内在经验的判断力介导了额叶纹状体功能连接对太极拳练习者对结局的情绪敏感性的影响。这些结果表明，长期太极运动可能通过减少额骨纹的功能连接，从而减少对内在经验的判断，并增强情绪调节，从而有效减轻老年人的后悔感。
