Clinical observations suggesting that perceptual distortions can take place during episodes of fear are described, and two hypotheses are set out: (1) perceptual distortions occur during episodes of fear, and (2) such distortions decline after reduction of the pertinent fear. An experiment in which fearful subjects were asked to report their perceptions of a feared object during episodes of fear, and then again after fear-reduction, was carried out. Snake-phobic and spider-phobic subjects showed evidence of some distortions in the activity of the pertinent fear object, but no distortions of size. After the reduction of the relevant fear, the subjects reported significant declines in the activity of the pertinent animal. The two hypotheses received partial support.
文中描述了临床观察结果，这些结果表明在恐惧发作期间可能会出现感知扭曲，并提出了两种假设：（1）感知扭曲发生在恐惧发作期间，（2）在相关恐惧减轻后，这种扭曲会减弱。进行了一项实验，要求恐惧的受试者在恐惧发作期间报告他们对恐惧对象的感知，然后在恐惧减轻后再次报告。怕蛇和怕蜘蛛的受试者表现出相关恐惧对象活动存在一些扭曲的证据，但没有大小扭曲。在相关恐惧减轻后，受试者报告相关动物的活动显著下降。这两种假设得到了部分支持。
