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.

    Like the phonological loop, it has limited capacity. In other words, it is possible, for example, to rehearse a set of digits in the phonological loop while simultaneously making decisions about the spatial layout of a set of letters in the visuo-spatial scratch pad.

  2. Primacy and Recency effect

    These findings can be applied to real life such as when revising, this technique could be used to improve revision skills by having to remember more things. As shown from the experiment that through rehearsal the items that you have learnt are stored in the Long Term memory.

  1. 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).

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

    He found that, if the tone was sounded immediately after the letters had been flashed on the screen, most participants were able to recall all four letters in the indicated row. Sperling's conclusions - * Information from a brief visual stimulus is stored in a high capacity sensory known as the iconic memory.

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

    The primacy effect therefore involves recalling from the long term memory. In the recency effect, participants tend to recall the last words in the list of words better. They also tend to be more accurate because the words have been recalled from the short term memory since those words were the last to enter the short 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.
