Abstract
This paper describes some common denominators between hypnosis and behavior therapy by means of a behavioral analysis of a group hypnosis treatment procedure. The treatment method involved interactional group psychotherapy under hypnosis, combined with cognitive and affective restructuring, and self hypnotic training utilizing visual imagery cues. The techniques capitalized on the vividness of the fantasy experience and the ease of changing emotional sets under hypnosis, to allow subjects to learn more adaptive affective responses and to rehearse more effective patterns of social behavior. The same treatment procedures are analyzed in a behavioral framework emphasizing the use of covert learning through imagery and the role of the therapist and the group as social reinforcers. It is proposed that a greater awareness of the use of learning principles by hypnotherapists would generate a more effective and systematic use of hypnosis.
