PES

Our work investigated whether individual differences in TPE are reflected in spontaneous brain activity in the resting state, as<br>assessed using ALFFs and RSFC. We found that higher PES was associated with higher ALFFs in the right insula and lower ALFFs in<br>the right subgenual cingulate, right dorsomedial prefrontal cortex, and right precuneus. These brain regions form functional<br>networks with other brain regions that together predict TPE levels. The above brain resting state spontaneous activity level data<br>indicate that individuals who are adept at sharing the positive emotions of others are more sensitive not only to emotional<br>stimuli from others, but also to the processing of positive emotional information. These individuals are also able to effectively<br>suppress the influence of negative emotional information. Furthermore, individuals with higher trait positive empathy may also<br>have less self-centered tendencies. These findings have important implications for our understanding of the nature of TPE and the<br>implementation of appropriate interventions. <br>本研究探讨了特质积极共情（Trait Positive Empathy, TPE）的个体差异是否可通过静息态自发脑活动得以体现，研究采用振幅低频波动（Amplitude of Low-Frequency Fluctuations, ALFFs）与静息态功能连接（Resting-State Functional Connectivity, RSFC）进行评估。结果发现，较高的积极共情得分（Positive Empathy Score, PES）与右侧脑岛（insula）的ALFFs升高相关，同时与右侧扣带回下区（subgenual cingulate）、右侧背内侧前额叶皮层（dorsomedial prefrontal cortex）及右侧楔前叶（precuneus）的ALFFs降低相关。这些脑区可与其他脑区构成功能网络，能够共同预测TPE水平。 上述静息态自发脑活动数据表明：擅长共情他人积极情绪的个体，不仅对他人的情绪刺激更为敏感，也能更高效地加工积极情绪信息；此外，这类个体还可有效抑制负性情绪信息的影响。进一步而言，特质积极共情水平较高的个体，其自我中心倾向往往更低。本研究结果对于理解TPE的本质以及制定恰当的干预措施均具有重要意义。
