Outline And Evaluate The Working Model Of Memory

Baddeley and Hitch proposed that computer storage board has 4 components. The bomberstitution executive director, phonological loop, visuo spacial sketchpad and the episodic buffer. The important executive decides how to sh be out and direct care to incoming nurture. The phonological loop shtup be thought of as a maintenance rehearsal mechanism for retaining communicative information. It is sub-divided into two other components, the phonological computer storage (inner ear), which holds acoustically coded information, and the articulatory process (inner voice), which allows for sub vocal rehearsal (words you are about(predicate) to say).Furtherto a greater extent, the visuospatial sketchpad (inner eye) is responsible for storing visual and spatial information. In other words, it codes information in images and locoweed create and manipulate visual and spatial images. Finally, the episodic buffer. This component takes information from contrasting sources and integrates th em together. For example, Baddeley suggested if we imagine an elephant playing ice hockey, we mystify to draw out images stored in desire term memory and combine them into a moving image.The working memory vex is good and is an improvement over the multi-store model. It demonstrates how the small term memory works because it explains how we undersur sheath store information briefly and simultaneously manipulate it, for example, mental arithmetic. This shows that the model has face validity, which means that the test appears to measure what it is intend to. There is certify to prove the humankind of the phonological loop.Baddeley thought that because longer chunks of information take longer to say, this may relate how a lot the short term memory can hold, rather than the capacity. This is known as the word length effect and it supports the existence of a phonological loop. However, there are also arguments to suggest weaknesses of the working memory model. The main limitati on is the lack of lucidity about the central executive. A psychologist argued that the central executive may be to a greater extent than just one system, possibly consisting of more than one component.This could make the working memory model appear reductionist because it has barely been described as being one(a) and over simplified. From this, it could be suggested that it is lacking in detail and is not fully reliable. Finally, much of the supporting evidence for this model was by one of the psychologists who proposed it (Baddeley). Here, assumptions could be made as to whether investigator effects play a part as Baddeley may essential to prove his beliefs. This means that the supporting evidence many not always be fully reliable.
