Fifty-six volunteer medical students participated in three groups balanced for number of subjects, performance at last examination, and hypnotizability. The hypnosis and waking groups attended eight group sessions once a week with general ego-strengthening and specific suggestions for study habits, with a ninth session of age progression and mental rehearsal. Subjects in these two groups practiced self-suggestions (in self-hypnosis or waking respectively) daily for the study period of 9 weeks. The control group experienced sessions of passive relaxation induced by light reading for the same period of time. The hypnosis group improved significantly in coping with examination stress, but there was no significant change in performance on examinations by any of the groups.
