Abstract
Imagery is widely agreed to be an important component of hypnosis. The theoretical framework from which to conceptualize the role of imagery in hypnosis, however, has remained controversial. A model is presented which attempts to reconceptualize hypnotic imaginal processing in terms of current theory and research in cognitive psychology and psychophysiology. This model draws from a propositional approach to imagery (e.g., Pylyshyn, 1973), particularly as adapted by Lang's (1979) bioinformational theory. It is argued that the hypnotic image is fundamentally more complex than simple iconic mental representation, containing instead both stimulus and response components. It is proposed that the critical properties of the hypnotic image are not the stimulus components or propositions which give rise to the experience of the image but instead are response propositions which are associated with overt behavior. Processing of these response propositions is conceptualized as a negative feedback system between the brain and effector site. Some preliminary sources of support as well as implications and research suggested by this model are discussed.
