Visual Information Analysis: The Roles Of Memory And Visual Memory

2357 Words5 Pages

In rational manner, visual memory can be defined as any memory for which the stored information was acquired by the visual system. However, such a definition is too broad. Thus visual memory encompasses memory representations that maintain information about the perceptual properties of viewed stimuli, but the format in which that information is encoded can vary from low level imagistic representations generated in early visual areas to higher level visual representations stored and abstracted away from the precise spatial structure of early vision.
The Visual Information Analysis (Todd 1999) incorporates areas related to the cognitive skills used for receiving and organizing visual information from the surrounding environment. The visual information …show more content…

Compared with iconic memory representations, VSTM representations are longer lasting, more abstract, and more durable. VSTM representations can survive eye movements, eye blinks, and other visual interruptions, and they may play an important role in maintaining continuity across these interruptions. VSTM is usually considered to be the visual storage component of the broader working memory system. VSTM is thought to be the visual component of the working memory system, and as such it is used as a buffer for temporary information storage during the process of naturally occurring tasks. The role of VSTM in bridging the sensory gaps caused by saccadic eye movements. These sudden shifts of gaze typically occur 2-4 times per second, and vision is briefly suppressed while the eyes are moving. Thus, the visual input consists of a series of spatially shifted snapshots of the overall scene, separated by brief gaps. Over time, a rich and detailed long-term memory representation is constructed from these brief glimpses of the input (Hollingworth, 2004), and VSTM is thought to bridge the gaps between these glimpses (Irwin, 1991) and to allow the relevant portions of one glimpse to be aligned with the relevant portions of the next glimpse (Currie, McConkie, Carlson-Radvansky, & Irwin, 2000; Henderson & Hollingworth,
