反刍与患抑郁症的高度脆弱性有关。然而，目前尚不清楚是哪些认知过程导致了反刍的个体差异。本研究旨在探讨工作记忆中不相关情绪刺激抑制的缺陷是否与消极情绪状态和消极生活事件反刍反应的个体差异有关。采用反应风格问卷（RSQ），评价高分者和低分者在消极情感启动任务中自我参照判断的表现。结果表明，在RSQ得分较低的被试中，情绪词汇的抑制作用显著，而在RSQ得分较高的被试中，情绪词汇的抑制作用不明显。当控制当前抑郁评分时，这些组间差异仍然显著，这表明无论抑郁症状的差异如何，反刍和抑制性功能障碍是密切相关的。
Rumination has been linked to a heightened vulnerability for the development of depression. However, it still remains unclear which cognitive processes underlie individual differences in rumination. The present study investigates whether deficits in the inhibition of irrelevant emotional stimuli in working memory are related to individual differences in ruminative responses to negative mood states and negative life events. Using the Response Style Questionnaire (RSQ), high and low scorers' performance in a negative affective priming task in which participants were asked for self-referential judgments was evaluated. The results show significant inhibition for emotional words in the participants who scored low on the RSQ but no inhibition for emotional words in the participants who scored high on the RSQ. These group differences remained significant when controlling for current depression scores suggesting that irrespective of differences in depressive symptomatology, rumination and inhibitory dysfunctions are closely related.
