Effects of Hypnosis on Regression to Primary-Process Thinking.

The authors tested the hypothesis that hypnotic age regression produces a shift from secondary- to primary-thought processing in hypnotizable participants. Thirty participants were tested for hypnotizability using the Elkins Scale of Hypnotizability (EHS). Participants were exposed to a tailored hypnotic arm-levitation induction and a hypnotic suggestion to age regress to 5 years of age and to have a dream.
