The multi-store model (MSM) of memory consists of three sections; SM (sensory memory), STM (short term memory), and LTM (long term memory). Information of the surroundings of an individual is moved from SM to STM when the information concerned is given attention. When information is in the STM maintenance rehearsal is required in order for the information to stay in the STM. If elaborative rehearsal is used on the information that is in the STM it is then transferred into the LTM, this is needed to remain in the memory without maintenance rehearsal and as a result of this the information is less likely to disappear from the memory.
Research that was carried out by Sperling in 1960 gives evidence for the MSM, this is because the experiment that was carried out showed that when reporting a group of 12 items that were flashed on a screen for 50 milliseconds, it was 42% less accurate than reporting only one row, which was 75%. This shows that information in the SM decays rapidly unless it is able to be transferred into STM and then into LTM.
Another piece of research that supports the MSM is that carried out by Glanzer and Cunitz. There research looked at the serial position effect. When the participants were asked to record the number of words they could remember from a list of 20 words it was found that the participants tended to remember the words that were at the beginning of the list because the words are rehearsed and therefore they are transferred into the LTM. Also the participants tended to remember the words from the end of the list because the words are still in the STM when they are recalled. However the words that were in the middle of the list were not likely to be recalled as much as the words that were located at the end of the list and the beginning. This is because the words would not have been rehearsed and they would be displaced from the STM when new words were shown.
Brain scans can also support the MSM because they show that when different...
