将30名大学生分为3组，根据设计的指示，以产生高估，低估或正确估计的强度，一个不可避免的，有害的声音刺激提供了一个20点计数的第10计数6次。结果表明：（a）预期期的生理唤醒与预期伤害性刺激的强度直接相关：（B）由于高威胁组对伤害性刺激的反应最大，但后来对刺激的反应最小，因此得出结论：即刻影响与预期直接相关，而重新评价受真实的刺激与预期刺激之间的对比影响;（c）在试验过程中，反应性降低，各组变得更加相似;（d）就心率而言，撞击前减速的增加有助于降低撞击后的心率。（PsycInfo数据库记录（c）2016阿帕，保留所有权利）
Divided 30 undergraduates into 3 groups according to instructions designed to produce an overestimate, an underestimate, or a correct estimate of the intensity of an unavoidable, noxious sound stimulus delivered on the 10th count of a 20-point count-up presented 6 times. Results show that:(a) physiological arousal during the anticipatory period was directly related to anticipated intensity of noxious stimulation;(b) since the high-threat group showed the greatest reaction to impact but later rated the stimulus as least intense, it is concluded that immediate impact varies directly with expectancy, while reappraisal is influenced by the contrast between the real and the expected stimulus;(c) over trials, there was a reduction in reactivity and the groups became more alike;(d) for heart rate, an increase in deceleration immediately before impact served to reduce heart rate immediately following impact.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
