Individuals who suppress their emotions experience less positive emotions, worse relationships, and a reduced quality of life whereas those who tend to reappraise show an opposite pattern. Despite this divergent pattern, few have asked how the use of these emotion-regulation strategies relates to reward responsivity. We predicted that elevated suppression would be associated with blunted reward responsivity, whereas reappraisal would be associated with elevated reward responsivity. To test this hypothesis, participants completed a measure of individual differences in emotion-regulation strategies, measures of self-reported reward responsivity, and then a reward time-estimation task (Kotani et al., 2003) while electroencephalography (EEG) was recorded. Results revealed that individual differences in cognitive reappraisal were unrelated to self-report measures of reward responsivity, whereas suppression was associated with blunted reward responsivity. At the neural level, reappraisal was associated with greater attention to the rewarding cues, as indexed by the P300 event-related potential (ERP) component, whereas suppression was related to blunted reward anticipation, as indexed by the stimulus-preceding negativity (SPN) ERP component. Suppression prospectively predicted worse psychological well-being 2.5 years later and blunted neural reward anticipation partially explained this association. Taken together with past research, these results suggest reappraisal tendencies may lead to better outcomes due, in part, to enhanced reward responsivity, whereas the negative consequences of suppression may be associated with blunted reward responsivity.
压抑情绪的个体体验到的积极情绪较少,人际关系较差,生活质量降低,而倾向于重新评价情绪的个体则呈现相反的模式。尽管存在这种差异模式,但很少有人探讨这些情绪调节策略的使用与奖励反应性之间的关系。我们预测,较高的压抑水平会与减弱的奖励反应性相关,而重新评价则会与增强的奖励反应性相关。为了验证这一假设,参与者完成了一项情绪调节策略个体差异测量、自我报告的奖励反应性测量,然后进行了一项奖励时间估计任务(Kotani等人,2003年),同时记录脑电图(EEG)。结果显示,认知重新评价的个体差异与奖励反应性的自我报告测量无关,而压抑则与减弱的奖励反应性相关。在神经层面,重新评价与对奖励线索的更多关注相关,以P300事件相关电位(ERP)成分作为指标,而压抑则与减弱的奖励预期相关,以刺激前负波(SPN)ERP成分作为指标。压抑前瞻性地预测了2.5年后较差的心理健康状况,而减弱的神经奖励预期部分解释了这种关联。与过去的研究相结合,这些结果表明,重新评价倾向可能部分由于增强的奖励反应性而导致更好的结果,而压抑的负面后果可能与减弱的奖励反应性有关。
