Outline and evaluate the Working Memory Model.
The Working Memory Model (WMM) is a model of the STM. The WMM was proposed by Baddeley and Hitch when they carried out a Dual-task method experiment only to find that the MSM was too simple as it stated that the STM is only one store. The model shows that information is first received by the Central Executive. The Central Executive has overall control of the STM and it is multi-modal meaning it can process information from different senses. This information can then go to one of two stores. If it is speech-based information it will be transferred to the Phonological Loop. It has two subcomponents, phonological store and articulatory control process. The phonological store is the inner ear and contains snippets of sounds either from the outside world or recalled from long term memory. The articulatory control process is the inner voice which essentially is our own voice inside our heads as it constantly repeats or rehearses information so therefore preventing forgetting by decay. The visuo-spatial sketch pad is visual short term memory, or the inner eye. It can manipulate images in two and three dimensions. The WMM shows memory as an active process as the Central Executive can store and retrieve information from either slave store. As this is a model of the STM, all three stores have a limited duration and capacity.
A good thing about the WMM is that it’s pioneering. This model is the first of its kind to explain STM as having separate stores rather than just one as explained in the MSM. Therefore, this pioneering model is useful as we can improve and build from it.
Another positive about the WMM is that there is evidence to support it. For example, KF only damaged his phonological loop. His visuo-spatial sketch pad was fine. Therefore, it proves that there are separate stores in the STM as only parts of KF’s STM were

Outline and Evaluate the Working Memory Model

...Outline and Evaluate the Working Memory Model The working memory model (WM) explains why we can do two different tasks at the same time, but not two similar tasks. It replaced the idea of a unitary short term memory (STM) in the working memory model information is passed from STM to the central executive and this decides if the information is visual or auditory. Information is then passed to the corresponding store. The central executive is a key component of the WM. It directs information from STM to one of the "slave systems" It also has a very limited capacity and duration so can't attend to too many things at once. The first "slave system" is the phonological loop. This deals with auditory information and maintains the order of the information. It consists of two stores, the phonological store which is like an inner ear and deals with sounds and the articulatory process is used for words which are heard or seen. These words are silently repeated (looped) like an inner voice. The next "slave system" is the visuo-spatial sketchpad. This deals with visual information and spatial information is the relationship between this information. This store is used when you have to plan a spatial task such as getting from one room to another or counting the number of windows your house has. Hitch and Baddley showed support for the WM by conducting an experiment where they gave participants two tasks to do at the same time. They found participants were slower completing these tasks...

Outline and Evaluate the Working Memory Model

...Outline and evaluate the working memory model In the working memory model, there are four main components; The central executive is the most important component as it is involved in problem solving and decision making. It controls attention and plays a vast part in planning and processing information from subsidiary systems and LTM. It is flexible and can process information. It has a limited capacity and can only contain a limited amount of information at one time, Secondly the phonological loop stores a limited amount of speech-based sounds for quick periods. It contains two components. The phonological store (inner ear) allows acoustically coded items to be stored for a brief timing. The articulatory control process (inner voice) allows subvocal repetition of the items stored in the phonological store. Repetition can be prevented by a technique known as ‘articulatory suppression’. The visuo-spatial scratch pad (inner eye) stores visual and spatial information. It is responsible for setting up and manipulating mental images. It has a limited capacity but the limits of the system are independent. The episodic buffer interrogates and manipulates material in the working memory. It has a limited capacity, depending a lot on executive processing. It is capable of binding together information from different sources into chunks/episodes. It interrogates material from LTM to meet the requirements of working memory. The working memory model has many advantages which are that it...

Outline and Evaluate Working Memory Model

...Atkinson and Shiffrin's (1968) Multi-Store model of memory was extremely successful in terms of the amount of research it generated. However, it became apparent that there were a number of problems with their ideas concerning the characteristics of short-term memory. Baddeley and Hitch (1974) developed an alternative model of short-term memory which they called working memory. Baddeley and Hitch (1974) argue that the multi-store model is too simplistic. Instead of all information going into one single store, there are different systems for different types of information. Working memory consists of a central executive which controls and co-ordinates the operation of two subsystems: the phonological loop and the visuo-spatial sketchpad. Baddley and Hitch investigated if participants can use different parts of working memory at the same time. They conducted an experiment in which participants were asked two perform two tasks at the same time - a digit span task which required them to repeat a list of numbers, and a verbal reasoning task which required them to answer true or false questions. The result was that as the number of digits increased in the digit span task, participants took longer to answer the reasoning questions, but not much longer. They didn't make any more errors in the verbal reasoning task as the number of digits increased. This was also known as the dual method. They concluded that the verbal reasoning task made us of the central executive and the digit span...

Outline and Evaluate the Working Memory Model (12 Marks)

...Outline and evaluate the working memory model (12 marks) Baddeley and Hitch proposed that memory has 4 components. The central executive, phonological loop, visuospatial sketchpad and the episodic buffer. The central executive decides how to share out and direct attention to incoming information. The phonological loop can be thought of as a maintenance rehearsal mechanism for retaining verbal information. 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). Furthermore, the visuospatial sketchpad (inner eye) is responsible for storing visual and spatial information. In other words, it codes information in images and can create and manipulate visual and spatial images. Finally, the episodic buffer. This component takes information from different sources and integrates them together. For example, Baddeley suggested if we imagine an elephant playing ice hockey, we have to draw out images stored in long term memory and combine them into a moving image. The working memory model is good and is an improvement over the multi-store model. 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. This shows that the model has face validity, which means that the test appears to measure what it is...

Outline and Evaluate the Working Memory Model Essay

...The working memory model (Baddeley and Hitch 1974) replaced the idea of a unitary STM, it suggests a system involving active processing and short term storage of information. The working memory model consists of four components which each have a different job. The Central executive (CE) is the key component and can be described as attention. It has a limited capacity and controls two ‘slave’ systems that also have limited capacity. The function of the CE is to direct attention to particular tasks, determining how the brain's ‘resources’ are used for the task. The ‘resources’ are the three ‘slave’ systems. Data arrives from the senses or from the long term memory. Because the CE has a very limited capacity it can’t attend to too many things at once and has no capacity for storing data. The next component is the Phonological loop (PL) which is one of the ‘slave’ systems. This deals with auditory information and preserves the order of information. Baddeley (1986) further subdivided this loop into: - The phonological store which holds the words you hear, like and inner ear. - An articulatory process which is used for words that are heard or seen. These words are silently repeated like an inner voice. This is a form of maintenance rehearsal. The next component is the episodic buffer which is another ‘slave’ system. Baddeley (2000) added the episodic buffer because he realised the model needed a general store. The Phonological loop and Visuo-Spatial Sketchpad...

Multi Store Model of Memory

...Outline and evaluate the multi-store model (12) | A01Atkinson and Shiffrin argued that there are three memory stores: 1. sensory store 2. short-term store 3. long-term storeAccording to the theory information from the environment is initially received by the sensory stores. (There is a sensory store for each sense.) Some information in the sensory stores is attended to and processed further by the short-term store. In turn some information processed in the short-term store is transferred to the long-term store through rehearsal or verbally repeating it. The more something is rehearsed the stronger the memory trace in the long-term memory. The main emphasis of this model is on the structure of memory on rehearsal | A02Case studies support to the multi-store modelGlanzer and Cunitz found that when rehearsal is prevented, the recency effect disappears.There is evidence that encoding is different in short term and long-term memory. For example Baddeley There are huge differences in the duration of information in the short term and long term memory (Peterson & Peterson). (Bahrick et al.)oversimplified.

Outline and Evalute the Working Memory Model (12)

...Outline and evaluate the working memory model. The working memory model was proposed in 1974 by Baddeley and Hitch, who felt that Atkinson and Schifrin’s multi store model, was too simplistic, therefore the working memory model acted as an alternative, unlike the multi store model the working memory model presents short term memory stores because it focuses on the short term memory. The term working memory is used by Baddeley and Hitch to refer to the part of the memory that is active, for example calculating sums or reading a sentence all of which are collecting data to be stored. There are three parts main of the original working memory model: the central executive, phonological loop, visual spatial sketch pad and the later added episodic buffer. The central executive controls attention and draws on the other the other two systems also known as slave systems. The central executive only has a limited capacity, which is supported by the dual task technique. This is when an individual struggles to do tasks that require the same component – this is because they are competing for the central executive’s capacity. There is evidence to suggest that there may be more than one component of the central executive, for example Eslinger and Damasio study. Their findings were that a patient, who had recently had a brain tumour removed, performed well on tasks that required reasoning, but not on decision making tasks. The two slave systems in the working memory model have similarities...

In what ways do consumers stray from a deliberative, rational decision process? CHAPTER SUMMARY 1.  Consumer behavior is influenced by three factors: cultural (culture, subculture,  and social class), social (reference groups, family, and social roles and statuses),  and personal (age, stage in the life cycle, occupation, economic circumstances,  lifestyle, personality, and self‐concept). Research into these factors can provide  clues to reach and serve consumers more effectively.   2.  Four main psychological processes affecting consumer behavior are motivation,  perception, learning, and memory.   3.  To understand how consumers actually make buying decisions, marketers must  identify who makes and has input into the buying decision; people can be  initiators, influencers, deciders, buyers, or users. Different marketing campaigns  might be targeted to each type of person.   4.  The typical buying process consists of the following sequence of events: problem  recognition, information search, evaluation of alternatives, purchase decision,  and postpurchase behavior. The marketers’ job is to understand the behavior at  each stage. The attitudes of others, unanticipated situational factors, and  perceived risk may all affect the decision to buy, as will consumers’ levels of  postpurchase product satisfaction, use and disposal...

Personal Knowledge Management : Who, What, Why, When, Where, How?

...Personal Knowledge Management : Who, What, Why, When, Where, How? Jason Frand and Carol Hixon December, 1999 Our students, who will spend most of their working lives in the 21 st century, will need to see the computer and related technologies as an extension of themselves, as a tool as important as the pencil or quill pen was for the last several hundred years. Fifteen years ago, few people knew what a personal computer was. Now personal computers are ubiquitous. With the proliferation of personal computers and linked computer networks, there has been an increase in the amount of information produced, as well as new avenues of finding the information. Personal Knowledge Management (PKM) attempts to utilize the computer to help the individual manage the information explosion in a meaningful way. What is personal knowledge management? It’s a system designed by individuals for their own personal use. Knowledge management has been described by Davenport and Prusak as a systematic attempt to create, gather, distribute, and use knowledge. Lethbridge characterizes it as the process of acquiring, representing, storing and manipulating the categorizations, characterizations and definitions of both things and their relationship. PKM, as conceived at the Anderson School, is a conceptual framework to organize and integrate information that we, as individuals, feel is important so that it becomes part of our personal knowledge base. It provides a strategy for transforming what might be random...
