Multi-store model Flashcards
Multi store model
Defenition
An explanation of memory that is based on three different stores and the information is transered between these.
Three terms- short term memory, long term memory and the sensory store.
Sensory store
Defenition
Where the initial coding first takes place, it is held for a very short time (half a second) and the method pf coding will depends on the organ that is involved (visual= eyes acoustic =ears)
Multi store model
origins
Atkinson and Shiffin (1968) gave the multi store model its name as it consists of three memory stores linked by processes that transfer information from one to the next.
Sensory store
Duration coding capacity
The capacity is very large if you pay attention.
if not attention is paid then it will only stay for a few milliseconds showing a limited druation
Attention is the process that takes it to the STM
Short term memory
Duration capacity coding
Limited duration 18/30 seconds and will quickly decay if its not reherased.
It has limited capacity as information will be dispalced if new information enters.
It is coded acoustically
Maintenance reherasal (repeating) the information so it will be sent to the LTM.
Long Term Memory
Duration capacity coding
The capacity and duration are both potentially unlimited and it is coded semantically.
The process is called retrival this is where you will get the information back from the LTM to the STM and making it ready for use
Mulit store model
Evaluation- Positive
The brain images can confirnm that there are differences in the stores.
Beardsley (1977) found that the frontal cprtext was needed for activites using STM and not LTM
Scovile and Milner (1957) case of HM
Multi store model
Evaluation- negative
There are different types of STM and LTM so this dosnt expalin the formation of Epesodic memories
Carik and lockhart (1972)- deeper processing is needed than juts maintenance rehersal as you need to complete both shallow and deep processing.
