The present study investigated whether individuals characterized by different emotion-control values (ECV) differed in their cognitive effort after being required to suppress emotions. Emotions of sadness were induced using a video clip and individuals were instructed to suppress their emotional expression. Behavioral measures of an event-related potentials related to Stroop task performance following suppression were obtained. Results show that whereas suppression led to attenuated error or conflict monitoring in low-ECV participants, as indicated by significantly lower error-related negativity amplitudes compared with ECV-matched controls, participants high in ECV did not differ from the controls. Emotion suppression in high-ECV individuals seems to come at a much lower cost and to be more effective in lowering both arousal and sadness than in low-ECV individuals.
本研究调查了具有不同情绪控制值（ECV）的个体在被要求抑制情绪后，其认知努力是否存在差异。使用一段视频片段诱发悲伤情绪，并指示个体抑制他们的情绪表达。获得了与抑制后Stroop任务表现相关的事件相关电位的行为测量结果。结果表明，与ECV匹配的对照组相比，抑制导致低ECV参与者的错误或冲突监测减弱，表现为错误相关负波幅显著降低，而高ECV参与者与对照组没有差异。高ECV个体的情绪抑制似乎成本更低，在降低唤醒水平和悲伤程度方面比低ECV个体更有效。
