Visual brief term memory (VSTM) is a memory system that stores visible info for a couple of seconds in order that it can be used within the service of ongoing cognitive tasks. Compared with iconic memory representations, VSTM representations are longer lasting, more summary, and more durable. VSTM representations can survive eye movements, eye blinks, and other visible interruptions, and they may play an necessary position in sustaining continuity throughout these interruptions. VSTM additionally differs markedly from long-time period memory (LTM). Specifically, whereas LTM has a just about infinite storage capability and creates richly detailed representations over a relatively very long time period, VSTM has a extremely restricted storage capacity and creates largely schematic representations very rapidly. VSTM is usually thought-about to be the visual storage element of the broader working memory system. 4 common classes of tasks have most frequently been used to check VSTM. In one class of duties, topics are are asked to create a mental image. In the Brook Matrix Job (Brooks, 1967), for example, topics are told a set of numbers and their relative spatial areas within a matrix (e.g., "place a 4 within the higher left corner
