Previous studies have shown that inhibiting negative or positive emotion-expressive behavior leads to increased sympathetic activation. Inhibiting facial behavior while in an affectively neutral state has no such physiological consequences. This suggests that there may be something special about inhibiting emotion-expressive behavior. To test the boundary conditions of the suppression effect, acoustic startles were delivered to 252 participants in three experimental groups. Participants in one group received unanticipated startles. Participants in the other two groups were told that after a 20-s countdown a loud noise would occur; participants in one of these groups were further told to inhibit their expressive behavior. Results indicated that startle suppression increased sympathetic activation. These findings extend prior work on emotion suppression, and suggest that inhibiting other biologically based responses also may be physiologically taxing.
先前的研究表明，抑制消极或积极的情绪表达行为会导致交感神经激活增加。在情感中立状态下抑制面部行为则不会产生这种生理后果。这表明抑制情绪表达行为可能存在一些特殊之处。为了测试抑制效应的边界条件，对三个实验组的252名参与者进行了听觉惊吓刺激。一组参与者接受意外的惊吓刺激。另外两组参与者被告知在20秒倒计时后会有一声巨响；其中一组参与者还被告知要抑制他们的表达行为。结果表明，惊吓抑制增加了交感神经激活。这些发现扩展了先前关于情绪抑制的研究，并表明抑制其他基于生物学的反应在生理上也可能是有负担的。
