Abstract
An experiment was designed to determine the effects of transmitting information concerning hypnosis (favorable information versus no information) and experimenter's attitude (friendly versus nonfriendly attitude) on the following dependent variables: subjects' attitudes toward hypnosis, expectations of their own hypnotizability, objective and subjective responsiveness to hypnotic suggestions, and self-ratings of hypnotic depth. Favorable information concerning hypnosis, but not experimenter's attitude, tended to raise subjects' expectations of their own hypnotizability and significantly raised their objective and subjective responses to hypnotic suggestions.
