Multi-Store Model of Memory. In this essay we will be looking at what research and evidence there is to support the model

Extracts from this document...

Introduction

´╗┐Unit Title: Psychology Kayleigh Giles-Johnson Multi-Store Model of Memory Atkinson and Shiffrin?s (1968, 1971) Multi-Store Model (MSM) is an early but influential model of memory which explains how information moves from short-term memory (STM) to long-term memory (LTM). In this essay we will be looking at what research and evidence there is to support the model, before comparing it with other memory models and looking at how these may offer alternative explanations to how memory works. The MSM explains that memory works by retrieving information from environmental input and storing it in the sensory memory, where if attended to, it will pass into the STM before passing through to the LTM only through the repeated rehearsal of the information. If information is not repeated, it will be forgotten through displacement (McLeod, simplypsychology.org). A strength of the MSM, as well as being the most influential model and the grounds for a lot of new memory research, is that there is a lot of evidence to support the idea, most notably that of the serial position effect. ...read more.

However, the model also has its weaknesses. It could be argued that it is in fact oversimplified and does not explain the full process of how information passes through. It has become more apparent that both LTM and STM are a lot more complicated than previously thought, and could be explained in a better way by looking at Baddeley and Hitch?s (1974) Working Memory Model (WMM). They argue that the multi-stores? idea of STM is far too simple, and that it is not a unitary store as the model might suggest. The WMM describes an alternative version of STM, known as working memory, in which it has different systems for different types of information. There is the Central Executive (CE), which drives the whole system and allocates information to the subsystems, whilst dealing with cognitive tasks such as problem solving and arithmetic. Then there are the Visio-Spatial Sketch Pad (VS), which stores information in a visual or spatial form, and the Phonological Loop (PL), which deals with spoken or written material, such as remembering a phone number (McLeod, simplypsychology.org). ...read more.

Conclusion

Liebermann also argues that the VS subsystem should perhaps be separated into two different components, as the two are not necessarily linked, such as in the case of blind people who have excellent spatial awareness yet no visual information in the first place (McLeod, simplypsychology.org). In conclusion, the Multi-Store model of memory does give a basic insight to how memory works and is the foundation on which many more ideas for memory have been built. However it has now been realised that it is in fact too simple and that alternative ideas such as the Working-Memory model may give a better look into how the information passes through from one system to the other. Both have considerable amount of evidence to support them and strengths and weaknesses of their own but do not focus on more than the passing of information from one storage system to another.

  1. Marked by a teacher

    Describe and evaluate the Multi-store Model of memory.

    3 star(s)

    The deepest level of processing involves coding the input in terms of its meaning. The variance here, between this model and Atkinson and Shiffrin's multi-store model, is that Craik and Lockhart disagreed with their theory in the area of how information enters the memory.

  2. Marked by a teacher

    Outline the multi store model of memory with evidence to support it

    The other form of forgetting in STM is trace decay. This is the physical decay of the connection between neurons when we remember things if it is not rehearsed. Long term memory has a limitless capacity; there is no evidence for it 'filling up'.

  1. SHORT TERM MEMORY

    It is clear that group 1 scored better recalls overall than those of group 2 as they has a higher mean shown on the graph. This was an average of 8.5 which when compared to an average of 7 demonstrates the difference between the two sets of data.

  2. Investigating the short-term memory

    The beep sound was again used, to make the investigation fair for all the participants. They were given another 60 seconds to recall and record the information in the scoring sheet. After the time was due, they were told to "stop writing" and their scoring sheet was collected.

  1. Case Studies relating to the Multi Store Model of Memory.

    He had no memory for events following the operation. His memory for events prior to the operation was reasonable, however, not as good as before. He could still talk and recall all the skills he previously knew but his memory didn't incorporate new experiences. In conclusion, the case study of Clive Wearing provides evidence for the multi store model,

  2. The effect of primacy and recency on recall

    The findings of this study showed that recall of adverts within the positions 1-3 were recalled most consistently (primacy effect), similarly with positions 13-16 (recency effect). Recall of adverts in the middle of the series was less consistent (positions 7-9).

  1. Evaluate 3 Approaches to treating Mental Disorders: Psychodynamic, Biological and Behavioural Approach.

    Tolerance can occur if a person takes these drugs for a long time, and withdrawal symptoms often appear when the drug use is discontinued. Antidepressant Drugs: Anti-depressants usually take a few weeks to have an effect and divided into three classes the first being Monoamine oxidase inhibitors (MAOIs)

  2. Alternatives to the multi store model of memory.

    The working memory differs from long term memory; long term memory is a separate part of the memory system with a vast storage capacity that hold information in a relatively more stable form. Working memory is an explanation of how short term memory works.
