Popis: This study explored how the expectation of hypnosis and the expectation of relaxation affected the vividness of visual imagery. 63 Ss who volunteered for a visual imagination study were randomly assigned to 4 groups. Ss were administered the vividness subscale (VS) of the Vividness and Control of Imagery Scale twice. In the 3 experimental groups, expectations were varied during the 2 VS administrations. All 3 groups were presented with a relaxation exercise between VS administrations. In 2 groups, it was labeled "hypnosis," and in the third group it was correctly labeled "relaxation." A control group listened to a neutral tape between their VSs. All groups were administered the Harvard Group Scale of Hypnotic Susceptibility, Form A (Shor & E. C. Orne, 1962) after the 2 imagery tests. The results indicated that the vividness of visual imagery was significantly enhanced (equally) in the experimental groups but not in the control group.
