Summary: In these experiments, the subjects were hypnotized and then exposed to various forms of suggestion to test their responsiveness. The first study involved reading fairy tales to the subject, which resulted in the subject transitioning into true sleep and then back into a trance state upon waking. The second study explored the dissociation hypothesis, showing that subjects can perform complex tasks while denying knowledge of it. The third study investigated the heightened suggestibility during hypnosis, demonstrating stable tendencies for perseveration of hypersuggestibility. Additional experiments examined indirect suggestions, age differences, and memory recall, highlighting the complexities of hypnosis and suggestibility. These studies shed light on the varied responses and behaviors of individuals under hypnotic states, challenging traditional beliefs and enhancing understanding of the phenomenon.
