The working memory model is the part of the short term memory which is governed by the ‘central executive which monitors and coordinates the operation of the store systems; Phonological loop and visuo – spatial sketchpad. The phonological loop allows sounds to be stored for brief periods. The visuo spatial sketchpad allows visual and spatial information to be stored for brief periods. The two slave systems within the WMM are completely separate and can work individually.…
Baddeley and Hitch (1974) developed an alternative model of short-term memory which they called the working memory model. The working memory model consists of four components. The central executive which controls and co-ordinates the operation of two subsystems, the phonological loop and the visuo-spatial sketchpad. The central executive controls attention and coordinates the actions of the other components, it can briefly store information, but has a limited capacity. The phonological loop consists of two parts, the articulatory control system and the phonological store. The articulatory control system (the inner voice) where information is rehearsed sub vocally and has a capacity of about 2 seconds. The phonological store (the inner ear) stores information in speech-based form, the speech input is held for a brief duration. The third component, the visuo-spatial sketchpad, mentally manipulates images and space, for example it is used when a person imagines the encodes visual information in terms of separate objects as well as the arrangement of these objects in one's visual field. The final component, episodic buffer, receives input from many sources, temporarily stores this information, and then puts them together in order to construct a mental episode of what is being experienced right now.…
Information in the short term (working memory) is either processed & stored, or not fully processed & is then forgotten.…
The Working Memory Model (WMM) is a theory by Baddeley and Hitch in 1974. The theory replaces the idea that there is a single Short Term Memory (STM) from Atkinson and Shiffrin (1968), it suggests that the STM is a flexible multi-component system. The WMM suggests that the STM is controlled by the Central Executive (CE) which controls attention, planning and synthesising information. The Central Executive is a flexible system which means it can process audio, visual and sound information, it also has a limited capacity.…
The working memory model (WMM) suggests that there are three main components to human memory. The central executive is the key component of working memory and is what directs attention to particular tasks, deciding which ‘resources’ (being the phonological loop and visual-spatial sketchpad) are allocated to which tasks. The central executive has a very limited capacity however, and can’t attend to too many things at once. The phonological loop (PL) too has a limited capacity and is what deals with auditory information; it is split into two further parts, the phonological store which holds the words you hear, and the articulatory process which is for the words you hear/see and are rehearsed…

The working memory model consists of three parts; these are the central executive, phonological loop and visuo-spatial sketchpad. The central executive controls attention and draws on the other two systems known as the ‘slave systems’. The central executive has a limited capacity; in other words it cannot attend to too many things at once. This is supported by the dual task technique in 1976 where participants were given two tasks to do simultaneously. The first task used the central executive which was a simple sentence verification task e.g. participants were asked to answer true or false when shown the sentence B is followed by A. The second task involved the central executive and the phonological loop where participants had to repeat the word ‘the’ over and over again whilst working out the sentence verification task. The third task used the central executive and the central executive and phonological loop. In this task participants had to say random digits between 1 and 9 whilst completing the sentence. Hitch and Baddeley found that the time taken on task 3 was significantly longer because the task involved using the same component, the central executive making completing the task more difficult. They also…
Working Memory- a newer understanding of short-term memory that focuses on conscious, active processing of incoming auditory and visual-spatial information, and of information retrieved from long-term memory.…
Long term memory is information that is stored in memory, but mainly outside our consciousness (MRC, 1993). However it can be recalled through our working memory (MRC,…
Working memory refers to how we manipulate the information that stored in the short-term memory. According to Baddeley's model of working memory, working memory is composed of three parts:…

Short-Term Memory is information that we are aware of or information that we think about. Most of the information that is stored in our short-term memory for a longer period of time than the Sensory Memory.…
There is a unique distinction between short-term memory and working memory. Short-term memory is used for holding small pieces of information over a short period of time and the working memory is part of the short-term memory that deals with immediate processes and scientists use it to refer to sustained neural activation. So even though the they directly correspond to one another, they have distinct differences that set them apart such as the tasks that each one is used to accomplish. Scientists here looks at a theoretical approach to the constructs of short-term memory and working memory.…
Sensory memory is the immediate processing of information, working memory is the sorting area in which information is categorized, and long-term memory is information that is retained and linked to information that was already learned (Schraw & McCrudden, 2013, pg 1).…
1) In case study one it is evident that HM’S long term memory is functioning as it states that he can still remember things about himself and things that had happened up until the operation. However the case study then goes onto prove how HM’S short term memory was damaged during the surgery. HM can now no longer remember anything after the surgery, no matter the importance, whether it was finding his way around his house or remember the death of his father. Another example where short term and long term memory has been disrupted would be Clive Wearing. Like HM, Clive can’t remember anything after his illness. The evidence proving this is that Clive can no longer enjoy books or TV serious as he can’t remember what happened…
