The Working Memory Model Was Proposed By Baddeley And Hitch

Working Memory The working memory model was proposed by Baddeley and Hitch in 1974. They replaced the concept of short- term memory, which was proposed in 1986 by Atkinson- Shiffrin model because they believed the model-lacked detail. Every day we have occasions where we keep particular pieces of important information briefly in our mind, storing them until an opportunity arises. For example remembering a phone number while you are hearing it and dialling it or holding directions in your mind until you get to that landmark (take the first right, continue for three miles, past the university and then the third exit at the roundabout). There might be times where the person can have solutions to a problem for example in a chess game.

The phonological loop contains the order the way words are presented and the visual- spatial sketchpad is used to hold visual information; the eyes are us ed to store and manipulate visual and spatial information such as remembering 3-D molecules or colour of solutions 5 6 7. All three-component work independently to other components. There are two assumptions that can be made: 1. If the task requires using the same component then it cannot be performed together successfully. 2. If both the tasks require different components; it should not be a problem performing both the task separate successfully. Phonological loop The phonological loop also known as the articulatory loop deals with sound or phonological information. The loop consists of two parts: a short term memory store with auditory memory traces which can rapidly decay and an articulatory rehearsal component that can recover the memory traces. It is assumed that articulatory verbal information automatically enters the phonological store. Information that is presented visually can be transformed into phonological code by silent articulation hence encoded into the phonological store 8. The sound of the speech is stored in the phonological store â€Å"inner ear† so that it can be remembered in the temporal order on the
