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不会产生这样的生理后果。这表明抑制情绪表达行为可能有一些特殊之处。为了测试抑制效果的边界条件，对三个实验组的 252 名参与者进行了声学惊吓。一组参与者受到了意想不到的惊吓。其他两组的参与者被告知，20 秒倒计时后会发出巨大的噪音；其中一组的参与者被进一步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的激活。这些发现扩展了之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也可能在生理上造成负担。
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 oil emotion suppression, and suggest that inhibiting other biologically based responses also may be physiologically taxing.
