Baddeley and Hitchââ¬â¢s Working Memory Model Essay -- Neurology Memory
This essay addresses the operative stock model which was proposed by Baddeley and Hitch (1974 in Smith & Kosslyn, 2007) as a solution to Atkinson and Shiffrins (1968 in Smith, 2007) multi-store model. tally to Baddely and Hitch the multi-store model failed to explain most of the complexities of the human depot and viewed it as being in any case simplistic. They argued that the short term memory store must have more components rather it being a single inflexible store as suggested antecedently by Atkinson and Shiffrin (1968). The working memory model is and so an enhancement of the multi store model. According to Baddeley and Hitch working memory is a limited- capacity system that stores and processes information. According to Baddeley and Hitch (1974) what constitutes as working memory can be divided into quaternion distinct components which contribute to the processes of memory. They are the phonological loop, the visual spatial sketchpad, the occasional(a) buffer and the c entral decision maker (in Passer, Smith, Holt, Bremner, Vliek, 2009).The primary role of the phonological loop is to store mental representations of auditory information (in Passer, 2009). It has limited capacity and holds information in a speech ground form. It is further subdivided into two more components the articulatory rehearsal system which has a limited capacity of 2 seconds and rehearses information verbally and is linked to speech drudgery and the phonological store which temporarily holds speech based information (in Smith, 2007)Evidence for the existence of the phonological loop comes from Baddeley (1966 in Passer, 2009) They examined the intelligence length effect in which they presented participants with visual presentations of word lists and asked them to write t... ...however issues such as reliability, validity and bias occur when studying brain damaged patients therefore is not always a valid way of studying working memory (in Smith, 2007).In conclusion, Bad deley and Hitch (1974) developed the working memory in response to the multi store model and introduced four mechanisms involved the phonological loop, visual-spaital sketchpad, episodic buffer and the central executive. The four components are also largely supported by a good wealth of attest (in Smith, 2007).ReferencesParkin, A. J., (1993). Memory Phenomena , experiment and theory. Blackwell.
