Eysenck's incubation theory of fear or anxiety was examined in a human Pavlovian conditioning experiment with skin-conductance responses as the dependent variable. The conditioned stimuli (CSs) were fear-relevant slides (snakes and spiders) and the unconditioned stimuli (UCSs) were aversive tones. Different groups of subjects were presented two tone intensities during the acquisition phase and three durations of nonreinforced CS (extinction phase) in a delay differential conditioning paradigm. Resistance to extinction of conditioned skin-conductance responses (conditioned fear responses) exhibited was largest for high intensity of tone and short presentations of the nonreinforced CS (CS+presented alone). The result tends to support Eysenck's incubation theory of anxiety.
在一项以皮肤电反应作为因变量的人类巴甫洛夫条件反射实验中，对艾森克的恐惧或焦虑潜伏期理论进行了检验。条件刺激（CSs）是与恐惧相关的幻灯片（蛇和蜘蛛），非条件刺激（UCSs）是厌恶音调。在延迟差异条件反射范式中，不同组的受试者在习得阶段呈现两种音调强度，在非强化CS（消退阶段）呈现三种时长。对于高强度音调以及非强化CS（单独呈现CS+）的短时间呈现，所表现出的条件性皮肤电反应（条件性恐惧反应）的消退抗性最大。该结果倾向于支持艾森克的焦虑潜伏期理论。
