This study examines the early affective consequences of two close forms of suppression. Participants (N=37) were shown negative, positive, and neutral pictures and cued either to attend to the pictures, or to perform expressive or physiological suppression (i.e., reduce body reactions). Continuous measures of experience, expressivity, and autonomic responses showed that both suppression strategies produced rapid response modulation. Common effects of the two strategies included a transient increase in negative feeling, a durable decrease in positive feeling, and a decrease in expressivity, cardiovascular activity, and oxygenation. The two strategies were significantly different only in response to positive stimuli, with physiological suppression showing a larger decrease in experience intensity and blood pressure. These results suggest a strong overlap between the two suppression strategies in terms of their early impact on emotional responses.
本研究考察了两种紧密的抑制形式的早期情感后果。参与者(N=37)观看了负面、正面和中性的图片,并提示他们注意图片,或者进行表达或生理抑制(即减少身体反应)。经验、表达和自主反应的连续测量表明,两种抑制策略都能迅速产生反应调节。两种策略的共同影响包括负面感受的短暂增加、正面感受的持久减少以及表达力、心血管活动和氧合作用的减少。这两种策略在对正性刺激的反应上仅存在显著差异,生理抑制表现出体验强度和血压的更大下降。这些结果表明,这两种抑制策略在其对情绪反应的早期影响方面具有很强的重叠性。
