Document Summary
Fraction of a second for iconic (visual) If sensory memory lasted longer, it would interfere with processing of new information. Whole report - report as many as you can. Partial report - report items in the cued row. So: limit is in reporting, not storing! Eidetic memory is an ability to vividly recall images from memory after only a few instances of exposure, with high precision for a brief time after exposure, without using a mnemonic device. Gives visual system more time to process information. All of these are benefits of iconic memory, except: Experience of perceptual continuity from moment to moment. Ability to replay auditory input (iconic memory is visual) For partial report, cued with a light in the probed location. Echoic memory, and partial-report advantage, fade in a few seconds. Blasts of air at different locations on fingers. Sensory memory receives information from the outside world. Information is lost from sensory memory through decay.
