Multi- store model Flashcards
memory
model of MSM
1) enviromental stimuli
2) enters the sensory memory (info is held at each sense)
3) if u pay attention then data transfers to STM
4) info is held in STM for immediate tasks
5) by maintenance rehersal ( repetition keeps info in STM but eventually it will create a LTM)
6) Retrievel is the process of getting info from LTM and passing back to STM to use.
who and what year did they come up with the MSM model
Atkinson and shriffin in 1968
evaluation that supports MSM
one case of a man called HM. his brain damage was caused by removing hippocampus from both sides of his brain to reduce epilepsy. His personality and intellect was intact but he was not able to form new LTMs but could still remember his things from before the surgery. This provided support to MSM as HM was unable to transfer info from STM to LTM but were able to retrieve information
Limitation of MSM
MSM suggests that STM comes before LTM however Logie pointed out that STM actually relies on LTM so therefore can not be first.
Ruchkin did a study by asking participents to recall a set of words and pseudo-words. They found out that there were much more brain activity when normal words asked compared to psuedo-words and this research shows that STM and LTM are not seperate and that STM is just a part of LTM
Capacity of Sensory Memory
high, info will only passed to STM if you pay attention
Duration of Sensory memory
half a second
Encoding of Sensory Memory
Visual
