The present study examined the mediating role of empathy in the quadratic relationship (an inverted U-shaped curve) between resting RSA and sharing behavior in 7- to 8-year-old children. Sharing behavior was measured using children's allocation of resources in the dictator game; the Griffith Empathy Scale-Chinese version was used to assess children's empathy. Resting RSA was calculated by electrocardiogram (ECG) data collected during a resting period in the laboratory. The results demonstrated a significant mediating effect of empathy in the quadratic association between resting RSA and sharing behavior. Specifically, moderate resting RSA was related to greater empathy and then contributed to more sharing behavior, while high and low resting RSA had a negative impact on empathy, which reduced the children's sharing behavior. The present study is the first to investigate the mediating role of empathy in the quadratic relationship between resting RSA and sharing behaviors. Accordingly, this study contributes to a better understanding of the psychological mechanisms that underlie the quadratic vagal tone-prosociality relationship.
本研究考察了同理心在 7 至 8 岁儿童静息 RSA 与分享行为之间二次关系（倒 U 型曲线）中的中介作用。分享行为通过儿童在独裁者游戏中的资源分配来衡量；使用 Griffith 同理心量表-中文版评估儿童的同理心。静息 RSA 通过实验室休息期间的心电图 (ECG) 数据计算得出。结果表明，同理心在静息 RSA 与分享行为之间的二次关联中具有显著的中介作用。具体来说，中等静息 RSA 与更大的同理心有关，进而促进更多的分享行为，而高和低的静息 RSA 对同理心产生负面影响，从而减少了儿童的分享行为。本研究首次探讨了同理心在静息 RSA 与分享行为之间二次关系中的中介作用。因此，本研究有助于更好地理解静息 RSA 与亲社会行为之间的二次关系背后的心理机制。
