The purpose of the current study was to determine if the relationship between interhemispheric interaction and cognitive flexibility extends to explanations of forgiveness and apology acceptance. A growing body of research indicates that consistency of handedness may be reflective of an individual's degree of interhemispheric interaction and access to processes of the right hemisphere. As such, individual differences in processing that require interhemispheric interaction, such as belief updating, are associated with consistency of handedness. Participants completed the Edinburgh Handedness Inventory (EHI) and read descriptions of interpersonal transgressions, then rated their willingness to forgive before and after an apology was offered. There was a main effect such that the presence of apology increased forgiveness. However, inconsistent handedness was associated with greater forgiveness prior to apology compared to consistent handedness. A second study was conducted to determine if the individual differences in forgiveness were mediated by different dimensions of empathy (personal distress, perspective taking, empathic concern and fantasy). Participants completed the Interpersonal Reactivity Index, the Forgiveness Scale and the EHI. Results revealed those with inconsistent handedness who scored lower on personal distress reported decreased negative thoughts about transgressors compared to those with consistent handedness.
本研究旨在探讨大脑两半球间相互作用与认知灵活性之间的关系是否可以扩展到解释宽恕和接受道歉的问题。越来越多的研究表明，惯用手的一致性可能反映了个体大脑两半球间相互作用的程度和右半球加工过程的可及性。因此，需要大脑两半球间相互作用的加工过程的个体差异，如信念更新，与惯用手的一致性有关。参与者完成了爱丁堡手性量表（EHI），并阅读了人际侵犯的描述，然后在道歉前和道歉后评估他们的宽恕意愿。结果表明，道歉的出现增加了宽恕的可能性。然而，与一致性相比，不一致的惯用手与道歉前更大的宽恕相关。第二项研究旨在确定宽恕的个体差异是否可以通过同理心的不同维度（个人困扰、换位思考、同理心关注和幻想）来解释。参与者完成了人际反应指数、宽恕量表和 EHI。结果表明，在个人困扰维度上得分较低的不一致惯用手的个体与一致性惯用手的个体相比，对侵犯者的负面想法减少。
