This study aimed to investigate the moderating effect of the desire for forgiveness on the association between relationship closeness and interpersonal forgiveness using event-related potentials (ERPs). We recruited forty student participants (20 males and 20 females) to complete the modified Taylor Aggression Paradigm (TAP), which was used to induce the offensive experience and record the victim's level of reactive aggression toward the offenders. Results indicated that for the internal intention of forgiveness behavior, when the desire for forgiveness was not expressed, participants were more forgiving of close offenders than strangers; when the desire for forgiveness was expressed, the internal intention of forgiveness behavior for strangers was similar to that for close offenders. Regarding the external performance of forgiveness behavior, whether the offender expressed the desire for forgiveness or not, participants exhibited more external performance of forgiveness behaviors toward the close offenders than the strangers. Furthermore, the decision-related negativity (DRN)—a negative component associated with aggressiveness—was larger when participants were considering the punishment of strangers when no desire for forgiveness was expressed. There was no significant difference when the desire for forgiveness was expressed. Moreover, the feedback-related negativity (FRN)—a negative component reflecting the evaluation of the valence of an outcome—was larger when participants lost a trial against strangers when no desire for forgiveness was expressed. No such difference was observed in both opponents when the desire for forgiveness was expressed. These findings confirmed that the desire for forgiveness moderated the association between relationship closeness and interpersonal forgiveness.

本研究旨在使用事件相关电位 (ERP) 调查宽恕欲望对亲密关系和人际宽恕之间关联的调节作用。我们招募了 40 名学生参与者（20 名男性和 20 名女性）来完成修改后的泰勒攻击范式 (TAP)，该模型用于诱导攻击体验并记录受害者对攻击者的反应攻击程度。结果表明，对于宽恕行为的内在意图，当没有表达宽恕的愿望时，参与者比陌生人更能宽恕亲密的冒犯者；当表达宽恕的愿望时，陌生人的宽恕行为的内在意图与亲密的罪犯相似。关于宽恕行为的外在表现，无论犯罪者是否表达了宽恕的愿望，参与者对亲密的犯罪者表现出比陌生人更多的宽恕行为的外在表现。此外，当参与者在没有表达宽恕的愿望时考虑惩罚陌生人时，与决策相关的消极性（DRN）——与攻击性相关的负面成分——更大。在表达宽恕的愿望时没有显着差异。此外，当参与者在没有表达宽恕愿望的情况下在对陌生人的审判中失败时，与反馈相关的负性 (FRN)——一种反映对结果效价评估的负面成分——更大。当表达宽恕的愿望时，在两个对手身上都没有观察到这种差异。
