Abstract
Abstract An appraisal is presented of Lang's theoretical and experimental work on emotional imagery. Lang has adopted a “propositionalist” theory of imagery which emphasises the role of the activation of cognitive structures associated with imagery. Questions are raised about the exact properties of these structures and the relation between their activation and the experiential image. Lang's experimental work has provided a generally convincing demonstration of the prediction that response training enhances the subjective vividness of imagery and the level of emotional responsiveness associated with it, although questions remain about the explanation of this effect. hg's predictions regarding the modification of emotional responsiveness associated with imagery have so far received little support from habituation studies, and the available data is considered in the context of the dual-process habituation theory of desensitisation.
