Discussing the multi store model of memory.

Introduction

Transfer-Encoding: chunked ´╗┐The multi-store model of memory (MSM) Discuss the multi-store model of memory (12 marks) The multi-store model of memory was proposed by Atkinson and Shiffrin and it is a structural model which describes how information flows through the memory system in a linear way. The memory system consists of three memory stores: sensory register, short-term memory and long-term memory. Both short-term memory and long-term memory are unitary. Sensory memory is the information which you get from your senses, your eyes and ears. When attention is paid to something in the environment it is then converted to short-term memory. If any information is not important, it will decay or disappear. Once information is in the short-term memory information can be rehearsed and some information is rehearsed and then passed along into long-term memory. ...read more.

This way information can stay in our STM but if it is rehearsed it can transfer into LTM. Long-term memory is known as the unlimited and permanent memory store for information which has been rehearsed over a prolonged time thoroughly. The coding for LTM is semantic and it can also be visual. For example, Bahrick et al (1975) found that many of their participants were able to recognise their classmates almost 50 years after graduating. Although this material is stores in LTM, when we want to recall information, it has to be transferred back into STM by a process called retrieval. Support for the multi-store model of memory is that research studies show that STM and LTM are in fact different, for example Baddeley found that we tend to mix up words in that sound similar in STM and we tend to mix up words that mean similar things in LTM. ...read more.

Conclusion

This is a limitation of the MSM because it is a research finding that cannot be explained by the model. Another limitation is that the MSM states is a unitary store, meaning that there is only one type of short-term memory- but research has found that there is in fact more than one type of STM. Evidence against this comes from Shalice and Warrington (1970) who studied a patient with a clinical condition called amnesia. They found that KF?s short-term memory for digits was poor when read aloud to him however, when he was able to read the digit himself his recall was much better. The unitary STM is a limitation of the MSM because research shows that at the very least there must be one short-term store to process visual information and another one to process auditory information. However, the working-memory model includes these separate stores. ...read more.

  1. Memory: Rote Rehearsal and Mental Imagery.

    for the rest of the population, a larger sample would be needed. All the participants were 16-18, all those under 16 were not accounted for and therefore it would not be fair to say that mental imagery affects everyone's memory because these people have not even been included.

  2. Investigating the short-term memory

    A field experiment is better for the investigation, as a laboratory experiment is more controlled, which could lead to a change in behaviour of the participants, and this could affect the end results of the investigation. To get the needed result for this investigation, the independent variable needs to be manipulated.

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

    in the English language, detect the number of times either the letter 'e' or 'g' occurred in the words, class the words by part of speech (whether it was a noun, adjective, verb etc.), or decide whether the words would fit into a given sentence frame.

  2. Investigation into acoustic and visual encoding in short-term memory

    Furthermore in a similar study, Conrad demonstrated that participants found it more difficult to recall strings of acoustically similar letters than strings of acoustically dissimilar letters even though they were presented visually. Conrad concluded that such acoustic confusion provided evidence for acoustic coding in STM.

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

    Independent groups were used so that it avoids order effects and this is also more convenient and saves time. Two groups were used because counterbalancing was needed to control for order effects. The independent variable was the position in which the words were placed in the list.

  2. Alternatives to the multi store model of memory.

    As the WMM says different areas of the pre frontal cortex were activated when performing two tasks affecting separate stores than when performing two tasks affecting the same store. This then supports the dual task nature of WM in an objective and scientific way.
