The influence of relationship closeness and desire for forgiveness on interpersonal forgiveness.

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. • The influence of relationship closeness on interpersonal forgiveness is well known. • Moderating factors of this association have not been explored. • We propose the desire for forgiveness by the offender as a moderator. • Experimental procedure used electrophysiology, the modified Taylor Aggression Paradigm. • Participants equally forgave strangers when desire for forgiveness was expressed.
