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. Information held in the STM is in a fragile state either because it simply decays or because new information comes along and displaces the old information if not rehearsed. If the information is sufficiently rehearsed it can enter LTM where limited information can be stored for as long as lifetime through semantic coding.

One of the strengths of the MSM is that it is supported by neurological case studies. The  MSM claims that STM and LTM are two separate store, which is supported by the case study of Clive Wearing. He had his hippocampus removed due to a viral infection which meant that he could not move information from STM into LTM. However, due to being a case study we must be cautious as it is concerned with a particular individual and therefore cannot be generalised to a whole population.

Further evidence for two separate store is provided by the medical technology ...
