High Quality Content by WIKIPEDIA articles! Iconic memory is the visual sensory memory (SM) register pertaining to the visual domain. 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 described as a very brief ( 1000 ms), pre-categorical, high capacity memory store. It contributes to VSTM by providing a coherent representation of our entire visual perception for a very brief period of time. Iconic memory assists in accounting for phenomena such as change blindness and continuity of experience during saccades. Iconic memory is no longer thought of as a single entity but instead, is composed of at least two distinctive components. Classic experiments including Sperling`s partial report paradigm as well as modern techniques continue to provide insight into the nature of this SM store.
