Evaluate the Working Memory Model - 1310 Words

Evaluate the Working Memory Introduction Human memory is a complex cognitive structure, which can be defined in many ways. One would argue that memory is 1.) The mental function of retaining information about stimuli, event, images, ideas, etc. after the original stimuli is no longer present. 2.) The hypothesized storage system in the mind that holds this information is so retained. A clear distinction is made between different types of memory systems and can be divided into subclasses. The first model of the human memory was proposed by Atkinson and Shiffrin in 1968. They introduced two different memory systems first, named after their capacity: Short Term Memory and Long Term Memory. Soon after they added a third memory store and†¦show more content†¦His study on word length effect comprised that participants had to read out as many words as they could than recall it. On the other hand the visuo-spatial sketchpad displays visulal and spatial information. All three elements has limited capacity, therfore if two tasks are from the same elements - like reading a paper and trying to have a conversation at the same time Ââ€" (phonological loop) are used they cannot be carried out properly. But if the tasks are form different elements it could be performed together. The forth element is the episodic buffer that again controlled by the central executive; holds a combination of different information from the phonological loop, the visuo-spatial sketchpad and the Long Term Memory. Disease in the Working Memory Store Working memory has been significant in mental work, and thinking. Baddeley (1996) carried out an experiment on patients with Alzheimer disease, as his suggestions included that aging and distributing information has a huge role in the central executive. His participants were given numerous digit-span trials, numbers as digits, and were asked to put a cross in each of the boxes positioned in an irregular pattern (dual task). Patients with Alzheimer disease proved a noticeable reduction in the mixed condition, but none in the normal tasks. M. C. McDonald (1998) suggested using different tasks and different materials in her study on individuals with Alzheimer disease. her patients had to undergoShow MoreRelatedOutline and Evaluate the Working Memory Model1210 Words   |  5 Pagespicture of short-term memory (STM) provided by the Multi-Store Model was far too simple. Following the Multi-Store Model, it is believed that STM holds limited amounts of information for short periods of time with relatively little processing, it is believed to be a unitary store. This means that due to its single store it has no subsystems, unlike the Working Memory Model which has many subsystems. This proves that the Working Memory is not a unitary store. Working Memory is STM. In contrast toRead MoreModels Of Theories Of Memory1235 Words   |  5 PagesEvaluate two models of theories of memory. This essay will evaluate two models of theories of memory. Memory can be defined as the persistence of learning over time via the encoding, storage, and retrieval of information. Encoding is the process of categorizing incoming information through conscious effortful processing, rehearsal, or unconscious automatic processing. The storage process involves the retention of encoded information over time. Lastly, retrieval is the process of getting informationRead MoreEvaluate two models of one cognitive process1042 Words   |  5 Pagesï » ¿Cecilia Nguyen Evaluate two models of one cognitive process This essay will be discussing one particular cognitive process: the memory by evaluating two models, which are the Multi store model introduced by Atkinson and Shiffrin in 1968 and the Working memory model by Baddeley and Hitch in 1974. The first model is the multi store model. It was first proposed by Atkinson and Shiffrin in 1968 and is a typical example of the information-processing approach.

These three tests capture various forms of memory (working memory, object recognition memory and fear memory) in mice and have translational validity for human drug screening for memory disorders. Based on the published data from our lab and others (Ref) our working hypothesis is that positive compounds will enhance memory storage. The following preliminary results support the feasibility of thisRead MoreEssay about Mulit-Store Model of Memory vs. Working Memory Model1101 Words   |  5 Pagescontrast the multi-store model of memory with the working memory model. This essay will firstly briefly describe the theories and important facts about the original multi-store model of memory (MSM) and the working memory model (WMM). This essay will then evaluate the key studies within these two models and explain the strengths and weaknesses of the main theories. The final part of this essay will be to examine the similarities and differences between the two models. The first issue that needsRead MoreThe Verbal Comprehension Index Measures The Ee107’S Ability1016 Words   |  5 PagesComprehension is a weakness for EE107, meaning that she may difficulty understanding oral language and expressing herself through words. The Visual Spatial Index measures the EE107’s ability to evaluate visual details and to understand visual-spatial relationships to construct geometric designs from a model. It is composed of the Block Design and Visual Puzzles subtests. On Block Design, EE107 viewed designs and used blocks to recreate each design. EE107 could correctly copy simple designs, but sheRead MoreEssay about Evaluation of Two Models Of Memory1413 Words   |  6 PagesTwo Models Of Memory In this essay 2 models of memory will be described and compared. They are the Atkinson and Sniffrin model of memory, the Multistore model, and Crain and Lockhart model, the Levels of Processing Model. Models of memory are primitive diagrams of human memory to help understand the flow of information and how it is stored. In order to evaluate those 2 models appropriately it is important to understand how old they are.
