Introduction

Describe and evaluate the multi store model of memory The multi-store model was developed by Shiffrin and Atkinson in 1968, it explains how information flows from one storage system to another, with three permanent structures in memory (sensory memory, short term memory, and long term memory). The sensory memory receives information from our senses, the information that we gain only lasts about ¼ of a second but If it is paid attention to then it will pass on to the short term memory. Short term memory is an active memory system containing information currently being thought about. It is a temporary storage of information received from the Sensory memory. Encoding in the short term memory (how we process the information) is mainly acoustic and based on sounds. Baddeley completed a research study that found acoustically similar words were more difficult to recall than words which were acoustically different. ...read more.

and memory only lasted 18 seconds, as rehearsal retains material within the short term memory loop, until eventually it becomes a permanent feature of the long term memory. The studies that were carried out for the short term memory were all carried out in a lab, to ensure control over extraneous variables and so the findings don?t really apply in an outside setting, also most memory experiments were carried out on students, and is difficult to suggest that all people will use memory in a similar way. The long term memory involves the storage of information over extended periods of time, potentially a whole lifetime. Forgetting from long term memory may not occur due to loss of information, but rather to problems in retrieving memory traces. Storage of information longer than 30seconds counts as long term memory. ...read more.

Conclusion

Items in the long term memory have a longer duration if originally well learned and certain forms of information have a longer duration like information based on skills rather than just facts. The three areas of the long term memory show that it is difficult to see how smells and tastes could be encoded semantically and reason suggests that songs must be encoded acoustically, supporting the idea of several forms of encoding in the long term memory. Also diary studies which are used in capacity studies are a type of case study and therefore are not representative of the general population. There is strong evidence to support the components of the multi-store model and it provides an account of memory in terms of both structure and process. The structures are the three stores and the processes are attentio0n and verbal rehearsal. However it is reductionist (oversimplifies memory structures and processes). And has been criticised for focusing too much on structure and too little on process. ...read more.

    The Levels of Processing Model, proposed by Craik and Lockhart, 1972, concentrates on the LTM and the semantic processing occurring there. It presents another alternative to the Multi-store model, which suggests information is transferred to LTM via rehearsal (repetition). This model suggests that the depth or level at which we

    Research evidence for the existence of a distinction between STM & LTM can be found in Glanzer & Cunitz (1966). This was an experiment in which participants were asked to recall a series of words and recall them in any order (free recall).

    All the selected participants were called into the classroom and asked to "please sit". They were all given a briefing sheet and asked to "read and asked question(s) if unclear of any information written on the sheet".

    The cognitive psychological approach was formed in the 1960s. This approach consists of the understanding of attention, memory, perception, information processing, problem solving, thought, language and other aspects of cognition. Piaget who was a Swiss psychologist researched on how to measure intelligence of an individual.

    he had no ability to update it, this means that he couldn't use his short term memory. Without short term memory HM couldn't transfer data to long term memory but he could still use his long term memory this means he couldn't rehearse.

    Baddeley found from this experiment that in STM words with similar sounds were harder to recall than those which sounded dissimilar. The similarity of meaning compared to the dissimilarity appeared to have no significant effect in STM. When participants recalled words in the long-term memory trial they performed much better

    And the second was that the deeper levels of analysis produce more elaborate,longer lasting and stronger memory traces than shallow levels of analysis. Shallow processing : these are when information is processed at a shallow level so encoding is based only on the physical qualities of something.
