Outline and evaluate the multi-store model of memory.

Outline and evaluate the multi-store model of memory. The Multi- store model (MSM) of memory was proposed by Atkinson and Shiffrin suggests that the memory is a flow of information through a system in a linear pattern. It consists of 3 distinct stages which are sensory memory (SM), short- term memory (STM) and long- term memory (LTM). the environmental stimulus first enters the SM in an uncoded form where it stays for a very brief period of time. In order for information to be passed to into STM, attention is vital. The STM can store ±7 items for approximately 15- 30 seconds acoustically. ...read more.


Further evidence for two separate store is provided by the medical technology such as PET and MRI scans which show different brain patterns when patients were carrying out tasks associated with STM and LTM. Similarly lab experiments such as the research on the primacy and recency effect also provide evidence for two separate stores. Glanzer and Cunitz found that the participants who were asked to remember a list of words could remember the first and last few words, while the middle one were more difficult to remember. This supports that idea that there are two separate stores as the first words were in the LTM, whereas the last words were still in the STM. ...read more.


Similarly, evidence from patients with amnesia indicates that there are different kinds of LTM rather than the LTM being a single store. Schachter suggested there are 4 kinds of long- term stores which are; semantic memory, episodic memory, procedural memory and perceptual- representation system memory. Another criticism of the MSM is that it overemphasises the role of rehearsal in form LTM. According to the MSM, elaborative rehearsal is the only way that information can pass from the STM to LTM. Lockhart and Craik?s study into levels of processing showed that information is more likely to be transferred into LTM if it is process at a semantic rather than acoustic and shallow level. ...read more.

    Describe and evaluate the Multi-store Model of memory.

    3 star(s)

    The multi-store cannot account for this. It is also criticised for focussing on the structure of the memory system at the expense of adequately explaining the process involved. For example, visual stimuli registered in sensory memory are thought to be changed to an acoustic code for access to STM.

  2. Primacy and Recency effect

    As from this experiment 20 participants were used so if this experiment was to be done again the participants used would be increased to 40. It will increase reliability significantly and give more generalisability to the target population. Then again, the number of subjects participating is and extraneous variable as it is difficult to determine how many will show voluntarily.

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

    Asked to recall them in any order (free recall) Condition 1: immediate free recall Condition 2: free recall after interference task To obtain results, plotted position of each word in the list against how many of the participant's recalled it. Results: - * Participants recalled more words at beginning (primacy)

  2. Outline and Evaluate the Multi Store Model of Memory and One Alternative Model

    These findings and the conclusion drawn from them supports the theory put forward through the Multi Store Model of memory. Evidence to demonstrate Atkinson and Shiffrin's claim that decay is the mechanism for forgetting in short-term memory is taken from the study performed by Glanzer and Cunitz (1966).

  1. An experiment to support the assumption that there are two distinct memory stores in ...

    This is due to the primacy and recency effect. In the primary effect, participants tend to recall the first words in the list of words better. This therefore shows that the first words have entered the short term memory store and have had time to be rehearsed before being passed on to the long term memory.

  2. Discuss research evidence associated with the multi store model

    It is increasingly doubted that there is a single long-term memory store. Studies have been made to prove to argue that there are separate memory stores. Peterson and Peterson did a study of the duration of short-term memory.
