One of the earliest documented accounts of the phenomenon was by Aristotle who proposed that afterimages were involved in the experience of a dream. The occurrence of a sustained physiological image of an object after its physical offset has been observed by many individuals throughout history. 6 Variations of the partial report procedure.2.2.1 Neural Basis of Information Persistence.2.1.1 Neural Basis of Visible Persistence.Classic experiments including Sperling's partial report paradigm as well as modern techniques continue to provide insight into the nature of this SM store. Iconic memory is no longer thought of as a single entity but instead, is composed of at least two distinctive components. Iconic memory assists in accounting for phenomena such as change blindness and continuity of experience during saccades. ![]() It contributes to VSTM by providing a coherent representation of our entire visual perception for a very brief period of time. Iconic memory is described as a very brief (<1000 ms), pre-categorical, high capacity memory store. It is a component of the visual memory system which also includes visual short term memory (VSTM) and long term memory (LTM). Iconic memory is the visual sensory memory (SM) register pertaining to the visual domain. ![]()
