Gill and Brenman (1959) hypothesized that sensory deprivation would enhance susceptibility to hypnosis. Most studies of hypnotizability have failed to confirm the Gill-Brenman hypothesis, but this may have been due to the fact that Ss were not in sensory deprivation during induction attempts. This is a report of one attempt to induce an hypnotic state together with a brief description of the procedure and results; further systematic investigation with a larger N is suggested.
