Multi store model and working memory model
This component helps us imagine a route from one place to another. The working memory model is a theory for how short-term memory works, and an expansion of the views expressed in the MSM theory. Further evidence for the existence of the phonological loop comes from Conrads and Hulls in Passer, experiment in which they examined the effect of phonological similarity.

One other strength is that as the model sates that tasks that require both components should require more brain activity. It demonstrates how the short term memory works because it explains how we can store information briefly and simultaneously manipulate it, for example, mental arithmetic. It stores both visual and spatial data here, but only temporarily. He performed well in reasoning tests which suggest that his central executive was intact however, tests which required decision making were performed poorly, and this means that his central executive was not completely intact. The visuo-spatial sketchpad stores and manipulates visual information and is a temporary store. The phonological loop can be thought of as a maintenance rehearsal mechanism for retaining verbal information. However, many positives and few challenges, then it is a very useful tool to understanding ourselves. The central executive is the main component of the working memory model it controls and directs attention to the other components by transferring the acoustic and iconic information to the phonological loop and the visuo-spatial sketchpad; this is due to the limited capacity of the store. This therefore suggests that more research into the central executive and working memory models is needed to make it more understandable. The phonological loop rehearses information to prevent loss and decay.
The findings also highlighted the difficulties of doing multiple tasks using the same store as oppose to using separate stores simultaneously. This is evidence of the two subsystems in working memory, as the ease of completion of the verbal and visual tasks must indicate two separate systems.
For example, if a theory has been used to improve the lives of people, then not only is the of benefit to humans, but it demonstrates that the theory is valid, because when used its predictions come true 15 Outline and evaluate the working memory model 16 marks See the practical applications offered at the bottom of page 10 and add notes to your plan.
This therefore suggests that more research into the central executive and working memory models is needed to make it more understandable.
This gives evidence that the central executive is more complex because it does not explain anything.
It works at delegating our attention to specific tasks, determining at any time how the two other components, the phonological loop and the visuo-spatial sketchpad, should be allocated different tasks.

Evaluate the working memory model essays
This component helps us imagine a route from one place to another. It works in conserving auditory information and preserves which order that information came in. According to Baddeley and Hitch working memory is a limited- capacity system that stores and processes information. In addition, Vallar and Papagno in Smith, found that the phonological store in brain damaged patients were dysfunctional. The role of the phonological loop in rehearsal has been supported however by experimental support by studies of the word-length effect. The findings also highlighted the difficulties of doing multiple tasks using the same store as oppose to using separate stores simultaneously. This component takes information from different sources and integrates them together. It is sub-divided into two other components, the phonological store inner ear , which holds acoustically coded information, and the articulatory process inner voice , which allows for sub vocal rehearsal words you are about to say. This is evidence of the two subsystems in working memory, as the ease of completion of the verbal and visual tasks must indicate two separate systems. This could make the working memory model appear reductionist because it has only been described as being unitary and over simplified. Even though there is evidence showing that the components are at work there is little information on how the central executive govern the other two components. To do this, we can analise the findings of psychological research studies to see if the data supports the assumptions in the model. This means that the supporting evidence many not always be fully reliable. Other participants had very little difficulty tracking the light if they were simultaneously completing a verbal task. But becareful not to repeat yourself here.
Here, assumptions could be made as to whether investigator effects play a part as Baddeley may want to prove his beliefs. Participants accomplished both tasks as well as they would have done if doing the tasks separately.
Phonological working memory
The phonological loop also has a restricted capacity. The working memory model is good and is an improvement over the multi-store model. These concepts lead them to form a model which consists of three slave systems; the central executive, the phonological loop and the visuo-spatial sketchpad. To do this, we can analise the findings of psychological research studies to see if the data supports the assumptions in the model. The visio-spatial sketchpad visually organises information to maintain visual memory, also known as the inner eye. Search for information about your subjects. In other words, it codes information in images and can create and manipulate visual and spatial images. The central executive is the main component of the working memory model it controls and directs attention to the other components by transferring the acoustic and iconic information to the phonological loop and the visuo-spatial sketchpad; this is due to the limited capacity of the store. Both of these findings are predicted by the WMM. Baddeley thought that because longer chunks of information take longer to say, this may affect how much the short term memory can hold, rather than the capacity.
It is the active system used to complete tasks, using 3 different parts. Make sure you state how these findings support the existence of WMM grounding Look at this example on the next slide, but you have to use two others… 9 Example of supporting evidence and grounding Gathercole and Baddeley found that participants found it very difficult to track a moving point of light on a screen, whilst simultaneously describing the angles of a hollow letter F.
This is known as the word length effect and it supports the existence of a phonological loop.
