One common strategy to cope with the difficulties of daily life is suppression. Habitual users of suppression tend to suppress their feelings rather than expressing them. Although this strategy may reduce outward response to emotion, it is not thought to lessen induced negative affect. Moreover, it remains unclear whether people with high suppression scores can reduce negative affect through cognitive reappraisal. In the present study, twenty-nine healthy participants differing in suppression scores were directed to reappraise aversive stimuli during functional magnetic resonance imaging (fMRI). Results showed that higher suppression scores correlated with decreased response of dorsomedial prefrontal cortex (dmPFC) during cognitive reappraisal. Further, high suppression scores related to enhanced negative affect to stimuli with greater negative affect correlating with decreased dmPFC response during cognitive reappraisal. This study suggests that people with high suppression scores experience difficulty in reducing negative affect through cognitive reappraisal and implicates neurobiological processes that may underlie this difficulty.
应对日常生活困难的一种常见策略是压抑。习惯性使用压抑策略的人往往倾向于压抑自己的情感而非表达出来。尽管这种策略可能会减少对外在情绪的反应，但人们并不认为它能减轻引发的负面影响。此外，目前尚不清楚压抑得分高的人是否能够通过认知重评来减少负面影响。在本研究中，29名压抑得分不同的健康参与者在功能磁共振成像（fMRI）过程中被引导对厌恶刺激进行重评。结果显示，在认知重评过程中，较高的压抑得分与背内侧前额叶皮质（dmPFC）反应的降低相关。此外，高压抑得分与对具有更大负面影响的刺激产生的增强负面情绪相关，而这种更大的负面影响又与认知重评过程中dmPFC反应的降低相关。这项研究表明，压抑得分高的人在通过认知重评减少负面影响方面存在困难，并暗示了可能是造成这种困难的神经生物学过程。
