The domain of hypnosis: A multifactorial model

dA conceptual framework is presented to help the reader understand some con troversies in the hypnosis literature and a means of understanding some imp ortant differences and disagreements in the field. It is this author's view that hypnotic behavior can be understood as a complex mix of four conceptu al (and empirical) independent dimensions: expectations, akin to the placeb o response in clinical technique; suggestion; a cognitive component includi ng relaxation, imagery in all modalities, and trance logic; dissociation, w hich is seen as the key component of deep hypnosis, and which may involve i ndividual differences in the flexible control of experience.
