The aim was to find out whether intoxicated and sober subjects would calibrate a shock scale to the same objective level and whether shocks received would be subjectively experienced in the same way in terms of pain and discomfort. The intention was also to replicate previous studies attributing an aggression enhancing effect to alcohol. The subjective ratings were made within the Taylor reaction time 'aggression machine'. Twenty-four subjects were randomly assigned to either an alcohol or a control group. The former drank 0.8 ml of pure alcohol/kg body wt. Results indicated no differences among groups on a shock setting measure of aggression under unprovoked or provoked conditions and no differences in level of calibration of shocks or in subjective ratings of pain and discomfort. These results were contrary to all predictions and are discussed as indirectly supportive of an hypothesis stating that this version of the 'aggression machine' may not generate a valid measure of aggression when used in alcohol research.
目的是探究醉酒者和清醒者是否会将电击量表校准到相同的客观水平，以及所接受的电击在疼痛和不适方面是否会被主观体验为相同的方式。其目的还在于重复先前将攻击增强效应归因于酒精的研究。主观评分是在泰勒反应时“攻击机器”内进行的。24名受试者被随机分配到酒精组或对照组。前者饮用了每千克体重0.8毫升纯酒精。结果表明，在无端或挑衅条件下，各小组在电击设置攻击测量方面没有差异，电击校准水平以及疼痛和不适的主观评分也没有差异。这些结果与所有预测相反，并被讨论为间接支持了一个假设，即当在酒精研究中使用这种版本的“攻击机器”时，可能无法产生有效的攻击测量。
