通过让人类受试者在习惯化过程中执行算术任务来操纵唤醒水平，该习惯化过程包括55次1000 Hz，80 dB音调的呈现。对于1组，在任务表现中添加了休克威胁，以便在唤醒操作中包括压力方面。将这两组与听到相同刺激但只是被指示放松的一组进行比较。3组的觉醒水平不同，根据脑电图的嗜睡迹象，皮肤电导水平和自发皮肤电导反应的频率。所有3组在对刺激的皮肤电导反应的习惯化标准的试验次数上彼此不同。由于习惯化的延迟在任务组和电击威胁组都有发现，这种影响并不局限于压力方面，而是一种普遍的唤醒增加的影响。对于血管反应，难以应用习惯化方面的分析，因为2个高唤醒组从一开始就非常无反应。
Level of arousal was manipulated by having human subjects perform arithmetic tasks during a habituation procedure which consisted of 55 presentations of a 1000 Hz, 80 dB tone. For 1 group a threat of shock was added to the task performance in order to include aspects of stress in the arousal manipulation. These 2 groups were compared with a group who heard the same stimuli but were simply instructed to relax. The 3 groups differed in level of arousal according to EEG signs of drowsiness, skin conductance level and frequency of spontaneous skin conductance responses. All 3 groups differed from each other in number of trials to habituation criterion for skin conductance responses to stimuli. Since the delay of habituation was seen for both the task group and the shock-threat group, the effect was not bound to aspects of stress but was a general effect of increased arousal. For vasomotor responses an analysis in terms of habituation was difficult to apply because the 2 high arousal groups were very unresponsive from the beginning.
