Random number generation, absorption, and hypnotizability: a brief communication.

Graham and Evans (1977) found that a measure of random number generation (RNG) was related to hypnotizability. In 2 studies, the relationship between hypnotizability and Graham and Evans' RNG (1977) index was examined. In Study 1 Evans' (1981) measures of controlled and automatic absorption were also evaluated. In Study 1 no relationship was found between the measures of absorption or RNG and hypnotizability. Since Study 1 was carried out primarily to evaluate methods for modifying hypnotizability, Study 2 was designed to evaluate RNG measure directly. Study 2 found no consistent relationship between RNG and hypnotizability, or between RNG and measures of the experience of hypnotic depth and nonvolition.
