the multi-store model Flashcards
1
Q
what are the components of the MSM?
A
- stimulus from environment
- sensory register (iconic, echoic, other sensory stores)
- short term memory store
- long term memory store
2
Q
what are the proceedings that link the stores?
A
- response / remembering
- maintenance rehearsal (loop)
- prolonged reversal
- retrieval
3
Q
what is the sensory register (SR)?
A
- stimulus from environment along with other senses passes into register
- duration = less than half a second
- capacity = very high (over a million in 1 eye)
- coding depends on sense like visual and auditory
4
Q
How does info transfer from SR to STM?
A
needs attention to be paid to it (rehearsal)
5
Q
what is the STM?
A
- duration = 18 - 30 seconds unless reversed
- capacity = 5 - 9 items
- coding = acoustic
6
Q
how does info transfer from Sim to LTM?
A
maintenance rehersal occurs when we repeat material (if it rehersed long enough it goes into ltm)
7
Q
what is the LTM?
A
- PERMANENT MEMORY STORE
- duration = upto a lifetime
- capacity = potentially unlimited
- coding tends to be semantic (with meaning)
- retrieval used to recall info from here
8
Q
What was the case study of HM?
A
- brain operation to remove hippocampus
- memory was assessed in 1955 but he thought it was 1953 and he was 27 (he was 31)
- LTM never improved but permed well on immediate STM tests
9
Q
+ supporting research evidence
A
- research shows STM and LTM are different as Baddeley found STM was acoustic and LTM semantic
- supports MSM that they are separate
10
Q
- Theres more than one type of STM
A
- Shalice and Waringdon (70) studied KF with amnesia whose STM for digits read to him were poor but good when he read them himself (STM store for non verbal sounds)
- MSM sates there only one type of STM but WMM includes multiple stores
11
Q
- More than one type of rehearsal
A
- says reversal good for transfer to LTM
- Craik and Watkins (73) found maintenance rehearsal just mains STM and elaborative rehearsal is instead needed for information transfer
