Atkinson and Shiffrin’s 1968
- The multi-store memory model (MSM) represents how memory is stored,
transferred between the different stores, retrieved and forgotten.
- There are 3 stores: the sensory register, short term memory and long-term
memory.
- The sensory register contains one sub-store for each of the 5 senses e.g. an echoic
store for auditory information.
- Since it receives information for our senses, the sensory register has a huge
capacity, but a duration of less than half a second. Therefore, information will only
pass from the sensory register to the short-term memory store if we pay attention
to it.
- STM is described as being acoustically encoded (Baddeley), having a capacity of
7+/- 2 items (Miller) and a duration of 18-30 seconds (Petersen).
- Maintenance rehearsal occurs when we repeat the new information to ourselves,
allowing the information to be kept in the STM. Prolonged maintenance rehearsal
allows the information to pass into the LTM, whilst a lack of such rehearsal causes
forgetting.
- LTM is described as being semantically encoded, having an unlimited capacity and
a very long duration (over 46 years, as shown by Bahrick et al). In order to remember
information, ‘retrieval’ must occur, which is when information is transferred back
into the STM, and will continue to pass through the maintenance loop afterwards.
