Abstract
We investigated previous findings that hypnotizability was unrelated to the ability to learn to control skin temperature. Twenty-six subjects were given the Hypnotic Induction Profile (HIP) and Stanford Hypnotic Susceptibility Scale (SHSS:C), Form C. Hypnotizability scores were then correlated with temperature changes recorded during two different periods in three different thermal biofeedback sessions. The two different periods consisted of a no-feedback recording period and a feedback recording period following a habituation period. HIP and SHSS:C scores were significantly correlated, r (24)= .60, p < .001. However, none of the scores on either hypnotizability measure correlated significantly with any changes in temperature during any period of any thermal biofeedback session. Clinical implications of these findings are discussed.
