Visuospatial sketchpad
From Wikipedia, the free encyclopedia
Visuospatial Sketchpad is a component of the working memory model that was proposed by Alan Baddeley and Graham Hitch in "Working memory." In G.A. Bower (Ed.), The Psychology of Learning and Motivation,Italic Vol. 8. New York: academic Press, 47-89 1974.
The visuospatial sketchpad (VS) is the section of one's normal mental facility which provides a virtual environment for physical simulation, calculation, visualization and optical memory recall. It is important to note that the visuospatial sketchpad is part of the working memory, and it holds the information it gathers during the initial processing of it and if it is retrieved later from the long-term memory, to produce the recollection of an image (a place, someone's face, etc.)
The degree of development and usage of the VS varies greatly from person to person. Some people use their visuospatial sketchpad often in normal thought processes, while others use it very little. It can be developed with practice using visualization and conscious effort, though everyone has their own limits of both patience and aptitude. As with all other aspects of memory, the more one tries to use the visuospatial sketchpad, the easier it will be. The mind can be "trained" to strengthen the response, and by doing exercises of visual recall, one can strengthen the VS to produce much sharper, clearer images on demand. Over time, the recollection of one image can change from a general recall to one with crisp detail through practice and patience.
