M2. Multi-Store Memory Model Flashcards
1
Q
Multi-Store Model (MSM)
A
- represents storage, transfer, and receipt of information between stores (and process of forgetting)
- Sensory register, short-term memory, long-term memory
2
Q
Sensory register
A
- contains 1 sub store for 5 sense (e.g. echoic store for auditory info)
- HUGE capacity; < 0.5 second duration
- information only passes from SR to STM if we PAY ATTENTION to it
3
Q
Short Term Memory (STM)
A
- acoustically coded (Baddley)
- 5 - 9 items (7+/- 2) (Miller)
- duration: 18-30 seconds (Petersen)
4
Q
Maintenance Rehearsal
A
- repeat new information to ourselves (attention), allowing it to be kept in the STM
- prolonged MR allows info to pass into LTM
- a lack of MR causes ‘forgetting’
5
Q
LTM
A
- semantically encoded
- capacity: unlimited
- duration: 46+ years (Bahrick et al)
- ‘retrieval’ occurs in order to remember info; information passed back into STM; and remains in ‘maintenance loop’ order to be remembered
6
Q
- Eval: Oversimplification: Different LTM Types
A
- Tulving et al.
- LTM NOT a single store
- procedural memory retrieved unconsciously
- semantic received consciously
7
Q
- Eval: Maintenance Rehearsal
A
- MSM suggests that amount of maintenance rehearsal determines how much information is transferred into LTM (directly proportional)
- Craik and Watkins: TYPE of Rehersal more important: elaborative rehearsal (linking knowledge) is more efficient than prolonged rehearsal
8
Q
- Eval: STM as a single store
A
- Patient KF had poor recall for auditory stimuli, but increasingly accurate recall for visual stimuli
- KF also able to differentiate and recall between both verbal and non-verbal sounds
- suggests multiple STM stores
