[Metacommunication in waking and hypnotic states]

A definition is given of the terms "communication" and "metacommunication", "language" and "metalanguage", and the several types of relationships that may arise in communication: "symmetrical competitive", "integrative complementary", "metacomplementary", and "paradoxical", Reference is made to the "spontaneity" and "simulation" that may arise in communication and metacommunication, during both wakefulness, conscious states in barbituric subnarcosis, and hypnosis. The question of metacommunication during the induction of hypnosis and during the hypnotic relationship is examined, stress being placed on the parapsycholgical metacommunications that may take place during some forms of self- or hetero-induced hypnotic consciousness.
