What evidence supports the existence of the visuospatial sketchpad?

Three main findings provide evidence for the distinction between visual and spatial parts of the visuospatial sketchpad: There is less interference between visual and spatial tasks than between two visual tasks or two spatial tasks. Brain damage can influence one of the components without influencing the other.

What is an example of visuospatial sketchpad?

If you’re drawing a flower, for example, you use the visuospatial sketchpad to hold a picture of the flower in your mind while you reproduce it on paper. While creating your drawing you have to either keep looking back at an actual flower or keep retrieving an image of a flower from your long-term memory.

Do blind people have a visuospatial sketchpad?

Measuring cognitive load of people who are blind or visually impaired can be considered different, because of their different memory model, their more active phonological loop and special sketchpad rather than visuospatial sketchpad [5] [6] .

What’s a visuospatial sketchpad?

The visuospatial sketchpad refers to our ability temporarily to hold visual and spatial information, such as the location of a parked car, or the route from home to a grocery store.

What is Visual cache?

visual cache. Sub-system of the visuospatial sketchpad whose function is the passive storage of visual information. The content of the visual cache is subject to rapid deterioration (unless the information is refreshed by the internal scribe) and to interference with new information (Logie, 1995).

What are the two primary components of the phonological loop?

The phonological loop has been referred to as STM because it involves two major components discussed in the STM literature: a speech-based phonological input store and a rehearsal process (see Baddeley, 1986, for review).

Does the visuospatial sketchpad have a limited capacity?

Working memory is a limited capacity store for retaining information for a brief period while performing mental operations on that information. Working memory is a multi-component system which includes the central executive, visuospatial sketchpad, phonological loop, and episodic buffer.

What does the visual cache store?

The visual cache, which stores information about form and color. The inner scribe, which deals with spatial and movement information. It also rehearses information in the visual cache and transfers information to the central executive.

What is proactive interference example?

Proactive interference refers to the interference effect of previously learned materials on the acquisition and retrieval of newer materials. An example of proactive interference in everyday life would be a difficulty in remembering a friend’s new phone number after having previously learned the old number.

What is the purpose of episodic buffer?

The episodic buffer acts as a ‘backup’ store which communicates with both long-term memory and the components of working memory.
