Lara Wainwright AS Psychology Outline and evaluate the multi-store model of memory (12 marks) There are three parts of the multi-store model of memory; sensory memory, short-term store and long-term store. The model was proposed by Atkinson and Shiffrin in 1968. The proposed that information enters the system from the environment and first registers on the sensory memory store where it stays for a brief period of time before either decaying or passing onto the short term memory store. Sperling (1960) did a sensory store experiment, which involved showing the participants three rows of letters (12 on the chart) for a split second which they then had to recall. The findings showed that only a fraction of the letters were passed on to the…show more content…
He thinks that performance on span tasks if often affected by rehearsal and long-term memory, and doesn’t reflect the capacity of ‘pure’ short-term memory. Individual differences can also affect short-term memory capacity, e.g. people who are highly anxious appear to have shorter spans. Duration refers to how long a memory is stored. Short-term memory is a temporary store and anything we need to retain for longer periods has to be transferred to long-term memory. Peterson and Peterson (1959) tried to find out how long items remain in short-term memory without rehearsal. Participants were presented a triagram consisting of 3 consonants, which they would have to recall in order after a delay of 3, 6, 9, 12, 15 and 18 seconds, but in-between they were given an interference task. This experiment gives us more knowledge about short-term memory because there results showed that very little information remained in the short-term memory for more than 18 seconds or so. The experiment was carried out in controlled conditions and there were no ethical issues to affect this experiment. However there were a few limitations, such as the use of triagrams are very artificial and not part of
