Spatial Working Memory
Working memory (WM) can be described as a limited capacity system that allows one to temporarily store and process information. This temporary store enables one to complete or work on complex tasks while being able to keep information in mind. For instance, the ability to work on a complicated mathematical problem utilizes one's working memory.
One highly influential theory of WM is the Baddeley and Hitch multi-component model of working memory. The most recent version of this model suggests that there are four subcomponents to WM, namely the phonological loop; the visuo-spatial sketchpad; the central executive; and the episodic buffer. One component of this model, the visuo-spatial sketchpad, is said to be responsible for the temporary storage, maintenance, and manipulation of both visual and spatial information.
In contrast to the multi-component model, some researchers believe that STM should be viewed as a unitary construct. In this respect, visual, spatial, and verbal information are thought to be organized by levels of representation rather than the type of store to which they belong. Within the literature, it is suggested that further research into the fractionation of STM and WM be explored. However, much of the research into the visuo-spatial memory construct have been conducted in accordance to the paradigm advanced by Baddeley and Hitch.

Famous quotes containing the words working and/or memory:
“Our policy is directed not against any country or doctrine, but against hunger, poverty, desperation and chaos. Its purpose should be the revival of a working economy in the world so as to permit the emergence of political and social conditions in which free institutions can exist.”
—George Marshall (1880–1959)
“Our memory is like a shop in the window of which is exposed now one, now another photograph of the same person. And as a rule the most recent exhibit remains for some time the only one to be seen.”
—Marcel Proust (1871–1922)
