Visible short term memory (VSTM) is a memory system that shops visual info for a few seconds so that it can be used within the service of ongoing cognitive duties. Compared with iconic memory representations, VSTM representations are longer lasting, extra abstract, and extra durable. VSTM representations can survive eye movements, eye blinks, and other visible interruptions, and they may play an necessary role in maintaining continuity throughout these interruptions. VSTM additionally differs markedly from lengthy-term memory (LTM). Particularly, whereas LTM has a virtually infinite storage capability and creates richly detailed representations over a comparatively long time interval, VSTM has a extremely restricted storage capability and creates largely schematic representations very rapidly. VSTM is usually thought-about to be the visual storage component of the broader working memory system. 4 basic classes of tasks have most often been used to review VSTM. In a single class of duties, topics are are asked to create a mental image. In the Brook Matrix Activity (Brooks, 1967), for Memory Wave example, subjects are told a set of numbers and their relative spatial areas inside a matrix (e.g., "place a 4 within the higher left nook
