13 Facts About Iconic memory

Iconic memory is the visual sensory memory register pertaining to the visual domain and a fast-decaying store of visual information.

Iconic memory is described as a very brief, pre-categorical, high capacity memory store.

Iconic memory is no longer thought of as a single entity but instead, is composed of at least two distinctive components.

Approximately 20 years after Sperling's original experiments, two separate components of visual sensory Iconic memory began to emerge: visual persistence and informational persistence.

Informational persistence which is the basis behind iconic memory is thought to be the key contributor to visual short term memory as the precategorical sensory store.

Two main components of iconic memory are visible persistence and informational persistence.

The characteristics of this component of iconic memory suggest that it plays the key role in representing a post-categorical memory store for which VSTM can access information for consolidation.

MOG activation was found to persist for approximately 2000ms suggesting a possibility that iconic memory has a longer duration than what was currently thought.

Iconic memory is influenced by genetics and proteins produced in the brain.

Iconic memory provides a smooth stream of visual information to the brain which can be extracted over an extended period of time by VSTM for consolidation into more stable forms.

Iconic memory enables integrating visual information along a continuous stream of images, for example when watching a movie.

Brief representation in iconic memory is thought to play a key role in the ability to detect change in a visual scene.

Development of iconic memory begins at birth and continues as development of the primary and secondary visual system occurs.
