通过让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次呈现或1000 Hz。80 dB音调。对于一组，为了在唤醒操作中包括压力方面，在任务表现中增加了电击的威胁。将这两组人与一组听到相同刺激但只是被指示放松的人进行比较。根据KEG嗜睡症状、皮肤电导水平和自发皮肤电导反应频率，三组在唤醒水平上存在差异。所有三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。由于在任务组和电击威胁组中都观察到了习惯化的延迟，因此得出结论，这种影响并不局限于压力方面，而是增加唤醒的一般影响。对于血管反应，很难应用习惯化方面的分析，因为两个高唤醒组从一开始就非常无反应。
Level of arousal was manipulated by having subjects perform arithmetic tasks during a habituation procedure, which consisted of 55 presentations or a 1000 Hz. 80 dB tone. For one group a threat of shock was added to the task performance in order to include aspects of stress in the arousal manipulation. These two groups were compared with a group who heard the same stimuli but were simply instructed to relax. The three groups differed in level of arousal according to KEG signs of drowsiness, skin conductance level, and frequency of spontaneous skin conductance responses, All three 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 tin- both the Task group and the Shock-threat group, it was concluded that 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 two high arousal groups were very unresponsive from the beginning.
