It is assisted by two sub-systems, the visuospatial sketchpad and phonological loop.
The visuospatial sketchpad is more closely associated with the central executive than the phonological loop and places greater demands on the central executive.
The storage capacity of the sketchpad is estimated to be one image.

 Working memory
The model has an executive control system, the central executive, and two "slave" systems, the phonological loop and the visuospatial sketchpad.
The visuospatial sketchpad holds visual and spatial information.
The visuospatial sketchpad appears to have separate processes for determine what something looks like (visual) and where it is located (spatial).

 Baddeley's Model of Working Memory - Wikipedia, the free encyclopedia
The visuo-spatial sketchpad is concerned with visual or spatial tasks, such as remembering shapes and colours, or the location or speed of objects in space.
The visuo-spatial sketchpad can be further subdivided into a visual component, dealing primarily with objects and their visible features, such as shape, colour, and texture, and a spatial component, dealing with locations and movements in space.
The strength of Baddeley and Hitch's model is its ability to integrate a large amount of findings on short-term and working memory.

 Miyake et al. (2001) JEP:General   (Site not responding. Last check: 2007-10-11)
One hundred sixty-seven participants performed visuospatial short-term memory (STM) and WM span tasks, executive functioning tasks, and a set of paper-and-pencil tests of spatial abilities that load on 3 correlated but distinguishable factors (Spatial Visualization, Spatial Relations, and Perceptual Speed).
Confirmatory factor analysis results indicated that, in the visuospatial domain, processing-and-storage WM tasks and storage-oriented STM tasks equally implicate executive functioning and are not clearly distinguishable.
These results provide a contrast witih existing evidence from the verbal domain and support the proposal that the visuospatial sketchpad may be closely tied to the central executive.

While the visuospatial domain has not been studied as extensively as the verbal domain, evidence suggests that the distinction between the STM and WM is not as pronounced in the visuospatial sketchpad as it is in the verbal domain (Miyake et al., 2001).
This extensive executive involvement even for the simpler visuospatial STM span tasks is consistent with the proposal that the visuospatial sketchpad is closely tied to the central executive as well as with the suggestion that the maintenance of even a single item may require central executive involvement.
The strength of the association between the visuospatial sketchpad and the central executive indicates that assessment of spatial tasks may be more closely related to general intelligence than to tests of verbal skills.

All participants exhibited deficits in verbal central executive measures, and 63% in both phonological loop and central executive.
The purpose will be to determine if the central executive deficits exhibited by the children with SLI on verbal tasks are also present in complex memory measures involving visuospatial tasks.
Children with SLI and two groups of typically developing control children matched for (1) age and (2) language will be compared on three complex visuospatial memory measures (odd-one-out, spatial span, Mr.

 Thinker: Memory: Working Memory   (Site not responding. Last check: 2007-10-11)
According to Baddeley's model, Working Memory consists of three components: the visuospatial sketchpad, the phonological loop, and the central executive, that work together to process incoming information.
The visuospatial sketchpad governs the processing of visual information, the phonological loop auditory information, and the central executive allocates information and energy to the correct component.
So, when you need to maintain visual information (such as an idea of what someone looks like), the central executive activates the visuospatial sketchpad; when the phonological loop is needed (such as to remember someone's phone number) the central executive activates it.

 Neuroscience Of Intelligence
The visuospatial sketchpad handles tasks involving visual memory and mental imaging.
It is thought of as a sketchpad, in that it is the theoretical system that allows for humans to visualize information.
Intelligence must be closely related to these systems, since much of intelligence could be explained on the basis of verbal fluency (the phonological loop), visuospatial skills (the visuospatial sketchpad), or logical processing (the central executive).

Working memory consists of several mechanisms including the phonological loop, visuospatial sketchpad, and the central executive.
The phonological store can maintain sounds or speech for one to two seconds and works with the articulatory control process that is equivalent to inner speech (Baddeley).
Baddeley suggests that the visuospatial sketchpad and the phonological loop are slave systems to the central executive.

Baddely (1990) considers working memory to consist of three components: a central executive component that co-ordinates the information from two storage systems, the visuospatial sketchpad and the verbal-phonological rehearsal loop.
Thus, the visuospatial scratchpad may provide the surgeon with details about the position of the particular body part to be operated on, as well as the positioning of surgical implements around the operating table.
We are quite capable of turning a vocalised word (such as "kangaroo") into an image of a kangaroo which is then kept active through the visuospatial scratchpad.

 Working Memory   (Site not responding. Last check: 2007-10-11)
There are two types of components: storage and central executive functions (see Baddeley, 1986 for a review).
The two storage systems within the model (the articulatory loop [AL] and the visuospatial sketchpad or scratchpad [VSSP] are seen as relatively passive slave systems primarily responsible for the temporary storage of verbal and visual information (respectively).
The most important, and least understood, aspect of Working Memory is the central executive, which is conceptualized as very active and responsible for the selection, initiation, and termination of processing routines (e.g., encoding, storing, and retrieving).
