以24名和30名男大学生为被试，进行了两个实验，以评估应激情境下几种认知因素对觉醒降低的作用。在Exp.我，Ss进行了一个令人厌恶的1/2小时休克避免程序，其中实验Ss有可选的控制休息时间，和一组轭控制有可比的休息时间强加给他们。实验组表现出实质性降低收缩压水平相对于他们的轭。结果表明，回避反应的可用性有唤醒减少的效果。在Exp.第二，休息期之前有一个可靠的信号。结果表明，预期收缩减少发生在与prerest信号，这些减少变化的功能，随后的休息时间的长度。(21参考文献）（PsycInfo数据库记录（c）2016阿帕，保留所有权利）
Conducted 2 experiments with 24 and 30 male undergraduates to evaluate the arousal-reducing function of several cognitive factors in stressful situations. In Exp. I, Ss underwent an aversive 1/2-hr shock-avoidance procedure, in which the experimental Ss had optional control over rest periods, and a group of yoked controls had comparable rest periods imposed on them. The experimental group manifested substantially reduced systolic blood pressure levels relative to their yoked counterparts. Results suggest that the availability of an avoidance response had an arousal-reducing effect. In Exp. II, the rest periods were preceded by a reliable signal. Results indicate that anticipatory systolic reductions occurred in conjunction with the prerest signal and that these reductions varied as a function of the length of the subsequent rest period.(21 ref.)(PsycINFO Database Record (c) 2016 APA, all rights reserved)
