Time distortion--a comparison of hypnotic induction and progressive relaxation procedures: a brief communication. 1991

Hypnotic experiences are frequently associated with alteration in temporal perception. 24 male and 24 female Ss were asked to estimate the interval associated with hypnotic, relaxation, or control procedures. Only the group that received the hypnotic condition displayed significant distortions in time estimations. These were primarily underestimations (temporal constriction or "time loss") compared to the more normal distributions of estimations for the other 2 groups of Ss. The hypnotic treatment explained about 35% of the variance in the absolute distortion of time estimates. The present study demonstrates that subjective distortions of time experience during a hypnotic procedure are more than an artifact of deep relaxation or instruction.
