How would I answer a question on memory models?

You would choose a specific memory model, for example, the Multi-Store Model of Memory. This was proposed by Atkinson and Shifrin and essentially explains the way in which they believe how memories are passed on from short to long term stores. ·     * Three step principle system that leads to the successful encoding and ability to retrieve information. * There’s a rehearsal loop believed to occur between the encoding of a short and long term memory which if travelled by a piece of information leads to its successful movement into long term memory. * By this model memories can only be lost from the long-term memory if by interference or damage, so instead remain there until a need to be retrieved. Diagram of the model:So your answer would begin with a brief description of the model after your intro (if you need help on structure of an intro we can go through that as well), and would be followed by a study to support the use of the model. In this case, a study relevant to this would be that of Peterson and Peterson. Aim: To test how long short-term memory lasts when rehearsal is prevented.Method: Participants were briefly shown a consonant trigram and then were asked to count backwards in threes from a specified number to prevent repetition. After intervals of 3, 6, 9, 12, 15 or 18 seconds the participants were then asked to recall the original trigram. Results: Participants were able to recall 80% of trigrams after a 3 second interval with progressively worse recall as the time intervals lengthened. After 18 seconds fewer than 10% of trigrams were recalled. Conclusion: If rehearsal is prevented, information vanishes rapidly from short term memory, therefore decay is evidently the mechanism by which memories are lost from the short term. Evaluation of Study:+ Random consonant use reduced participants ability to make associations with trigrams and known words. + Strongly supports the multistore memory model as an accurate representation of how memories are encodedTrigrams are a very artificial representation of everyday memory tasks It is possible that the interference from the counting and not merely the decay that resulted in poor recall. Linking point back to question: The results of this data demonstrate that if information is not repeated it decays rapidly from memory which is supported by the idea in the multistore memory model that information has to go through a rehearsal loop in order to remain in long term memory. Then, conclusion.
