The author continues the proposition that hypnosis is a complicated phenomenon by debunking some popular conceptions concerning the nature of posthypnotic behavior. He presents material, which is largely experimental, showing the following points: 1, a trance induction procedure is not necessary to elicit responses to 'simple' posthypnoticlike suggestions; 2, a waking control group may be as responsive as a hypnotized group to more 'difficult' posthypnoticlike suggestions, such as to dream at night on a selected topic. A 'good' hypnotic subject does not have to re-enter a trance while carrying out the posthypnotic suggestion, nor is the performance of the act necessarily forgotten.
