Dynamics of hypnotic analgesia: some new data.
Following two surgical operations under hypnotic anesthesia, it was possible, during subsequent recall under hypnosis, to elicit a representation of the past operative experience. It would seem that under hypnosis there is a persistence of the preception of nociceptive information and of its recognition as such by the subject. From an analysis of these two experiments in recall, it is possible to formulate several hypotheses concerning the psychological processes involved in hypnotic analgesia. In consequence of an affective relationship, in which the hypnotist's word assumes a special importance for the subject, the latter has recourse to two kinds of mechanism: a) internal (assimilation to an analogous sensation, not, however, registered as dangerous-rationalization); and b) external (total compliance with the interpretations proposed by the hypnotist), which lead to a qualitative transformation of nocieceptive information, as also the inhibition of the behavioral manifestations normally associated with a painful stimulus.
