暴露64名大学生的图片恐惧（蛇）和所谓的中性（人脸或房屋）的物体作为条件刺激（CS）在经典的条件反射实验与冲击作为非条件刺激（UCS）和皮肤电导反应作为因变量。一组被恐惧症图片震惊，另一组被中性图片震惊。在10次采集试验中，两组在CS和前UCS反应上表现出相同的条件反射。然而，在灭绝，有持久的条件反射的影响，在CS和，在较小程度上，后UCS反应恐怖，但不是中性刺激。不再给予电击的指示似乎对改变CS反应无效，但对UCS后反应无效。它的结论是，目前的实验情况可能作为一个实验模拟恐惧症。（PsycInfo数据库记录（c）2022阿帕，保留所有权利）
Exposed 64 undergraduates to pictures of phobic (snakes) and supposedly neutral (human faces or houses) objects as conditioned stimuli (CSs) in a classical conditioning experiment with shock as the unconditioned stimulus (UCS) and skin conductance responses as the dependent variable. One group was shocked on the phobic and another on one of the neutral sets of pictures. During 10 acquisition trials both groups showed equal conditioning on CS and pre-UCS responses. During extinction, however, there were lasting conditioning effects in CS and, to a lesser extent, post-UCS responses to phobic but not to neutral stimuli. Instructions that no more shocks would be given seemed ineffective in modifying CS, but not post-UCS, responses. It is concluded that the present experimental situation may serve as an experimental analog of phobias.(PsycInfo Database Record (c) 2022 APA, all rights reserved)
