Evaluate two models of one cognitive process

Memory is divided into three categories. These categories consist of: sensory memory, short term memory and long term memory, out of these short term memory is the main focus in this essay. It has been widely researched due to interest of how much memory can be stored, how long this memory can be stored for and what information is memorised.

Atkinson’s and Shiffrin’s (1968) multi-store model was extremely successful in terms of the amount of research it generated. However, as a result of this research, it became apparent that there were a number of problems with their ideas concerning the characteristics of short-term memory. Building on this research, Baddeley and Hitch (1974) developed an alternative model of short-term memory which they called working memory. Baddeley and Hitch (1974) argued that the picture of short-term memory (STM) provided by the Multi-Store Model is far too simple. According to the Multi-Store Model, STM holds limited amounts of information for short periods of time with relatively little processing. It is

The multi-store model of memory (eg, Atkinson and Shiffrin 1968) claims the memory can be sectioned into three distinctive parts: sensory store, short-term store (STM) and long-term store (LTM). Eysenck and Keane (2005:190) states that data is first encountered by the sensory store, then depending on the attention given, is processed to the STM and finally - if rehearsed - continues to the LTM.

In the last half century several theories have emerged with regard to the best model for human memory. In each of these models there was a specific way to help people recall words and

The working memory model has been used to explore a range of human behaviour. With reference to just one aspect of functioning, critically evaluate how successful the working memory model is at providing an explanation.

In 1974 the researchers Baddeley and Hitch argued that the picture 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.

Question 14 of 35 1.0 Points The store model of the information-processing system assumes that A. automatic cognitive processing expands the capacity of working memory. B. the central executive directs the flow of information in the cognitive system unconsciously. C. long-term memory is limited in capacity. D. sensory information is represented directly and briefly in the short-term memory without being filtered by attention. Reset Selection

Memory in the human brain is a complex process which is easier understood by the use of theoretical constructs. Memories begin as sensory stimuli which become sensory memory which only last about one second, from there it moves into working memory which lasts for about twenty to thirty seconds and is used to process information. Within working memory there are a few separate processes, the central executive which directs attention, the episodic buffer which is a secondary storage lasting ten to twenty seconds, this area communicates with long term memory as well as the central executive. The visuospatial sketchpad which is used to visualise visual and spacial

Baddeley (2001) suggests a working memory system which consists of four components; a modality-free central executive, a phonological loop which holds information in speech based form, a visuo-spatial sketchpad and an episodic buffer which is the temporary storage system that holds and integrates information from the phonological loop, visuo-spatial sketchpad and long-term memory (Eysenck & Keane, 2005).

Baddeley and Hitch determined that this working memory should be divided into three parts based on the type of information it processes. The first part, deemed the central executive area, acts as a boss sending data to the other areas while dealing with cognitive tasks such as problem solving on its own. The visuo-spatial area stores and processes visual information and is responsible for navigation. Finally, the phonological loop stores and processes written and spoken materials and would be responsible for memorizing a telephone number. The phonological loop is further broken down into two parts, the phonological store, which holds spoken information, and the articulatory control process, which is used to store verbal information from the phonological store. In 2000, based on a failure to explain experimental results, Baddeley decided to add the fourth part called the episodic buffer. This component is responsible for communication between long-term and episodic (short-term) memory and serves as a backup (Mcleod, 2008). Working memory and short-term memory are often interchanged, however working memory commonly includes the active processes in the brain that make up the short-term memory, while the term short-term memory solely refers to the brain’s ability to temporarily store

Baddeley and Hitch (1974) criticised the multi-store model for being a very simplistic view of memory. They saw short term memory as a store that had many individual sections inside it. This was supported by patient KF who had epilepsy, the doctor wanted to try and remedy this by removing his hippocampus. This surgery was done, however instead of fixing his epilepsy, it damaged his short term memory, yet he still had his long term memory intact. In the multi-store model it states that in order to have long term memory, one needs to have gone through the several stores, such as the sensory memory store, the short term memory and then by adding meaning and rehearsal, into the long term memory store. Seen as patient KF could still encode long

Working memory's current understanding largely stems from the model in 1974 by Baddeley and Hitch, since then it has been recently advanced. The boss being the central executive, who controls and monitors all the information processing. The two other separate storage systems that support the central executive: phonological loop, who functions as the temporarily store for phonological information, and the visuospatial sketchpad where visual and spatial representations are temporarily stored and manipulated (Baddeley, 1996). The integrator of information from the subcomponents of working memory and long term memory is known as the episodic buffer, it is the recently proposed addition (Baddeley, 2000). Many people when they think of an individual

This essay addresses the working memory model which was proposed by Baddeley and Hitch (1974 in Smith & Kosslyn, 2007) as a response to Atkinson and Shiffrins (1968 in Smith, 2007) multi-store model. According to Baddely and Hitch the multi-store model failed to explain most of the complexities of the human memory and viewed it as being too simplistic. They argued that the short term memory store must have more components rather it being a single inflexible store as suggested previously by Atkinson and Shiffrin (1968). The working memory model is therefore an enhancement of the multi store model. According to Baddeley and Hitch working memory is a limited- capacity system that stores and processes information.

Memory is a cognitive process that allow us to stored, retrieved, and encoded information. Storage is where the information goes, retrieved is where you get the information, and encoding is where the information is processed. A model that supports the cognitive process is the multi-store model (MSN) and according to the MSM the human memory can be divided into three stores of memory.

Memory is defined as "the persistence of learning over time through the storage and retrieval of information." Our memory can be compared to a computer's information processing system. To remember an event we need to get information into our brain which is encoding, store the information and then be able to retrieve it. The three-stage processing model of Richard Atkinson and Richard Shiffrin suggests that we record information that we want to remember first as a fleeting sensory memory and then it is processed into a short term memory bin where we encode it ( pay attention to encode important or novel stimuli) for long-term memory and later retrieval. The premise for the three step process is that we are unable to focus on too much
