Outline and evaluate the model of working memory In this essay I am going outline what is working memory in terms of psychology and evaluate it in terms of both advantages and limitation of the working memory model. The fact that short-term memory contains both new information and information retrieved from long-term memory has led some psychologists to prefer the term ‘working memory’ (Baddeley and Hitch, 1974; Baddeley, 1986,1992) Working memory model is an alternative to the multi-store model; it is a far more complex explanation of short-term memory. Baddeley and Hitch argued that the short-term memory was made up of several subsystems, each of them have a specialized function, rather than the short-term memory model being a single inflexible store. According to Martin, G. N, Carlson, N.R & Buskist, W. (2006) “According to Baddeley, working memory is a short-term memory system that allows us to retain material for current use and not just for transport into long-term memory.” Baddeley suggested this short-term memory as having three independent components that allow us to store temporarily visuo-spatial material and verbal material. These components were so-called the Visuo-Spatial Sketchpad and the Phonological Loop. Baddeley and Hitch suggested that these two subsystems were governed by central controlling mechanism, which they termed the Central Executive. The Phonological Loop acts like an inner ear and operates like the loop of an audiotape. It can hold spoken information for about 1-2 seconds. Written words must be transferred into spoken words in order to enter the phonological loop. Information is then transmitted back to the articulatory system, when the word is silently repeated. The loop continues until the individual’s attention turns to something else or until it is replaced with new information. (Martin, G. N, Carlson, N.R &
