Fearful distortions.

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.
