This study was concerned with the effects of hypnosis on the memorization of nonsense syllables. 32 undergraduates, 16 relatively susceptible and 16 relatively unsusceptible, were individually presented 10 nonsense syllables on a memory drum under counterbalanced hypnotized and unhypnotized conditions. Findings demonstrated that hynosis facilitates the performance of the relatively unsusceptible Ss, and impairs the performance of the very susceptible ones. Hypnosis was thus seen as having potentially variable effects which interact with susceptibility and with the specific experimental measure which is used.
