ABSTRACT

One of the most robust findings in the literature on hypnotic suggestibility is that there are large individual differences in the extent to which people respond to imaginative suggestions. Although approximately 15 per cent of people respond to very few suggestions, a comparable percentage of individuals respond to a wide range of suggestions for changes in sensation, perception, cognition, and action. Many highly suggestible individuals are able to experience involuntary or automatic movements, vivid hallucinations, age regression, anesthesia, compulsive posthypnotic behavior, and amnesia in response to suggestions.
