(3) MULTI-STORE MODEL OF MEMORY

Question 1

Draw out and label the MSM

Answer 1

Question 2

What is the CAP, DUR AND COD of each store in MSM

Answer 2

Question 3

MSM eval (4 good, 3 bad)

Answer 3

Good:

Sperling:
- Sensory register = huge capacity, small duration
1. Flashed 12 letters for 50 milliseconds
○ Asked to write all 12
○ Remembered 3/4 (33%)
2. Same thing
○ Asked to write letters from specific row asked (high, mid, low)
○ Remembered 2/3 (17%)

Glanzer and Cunitz:
- Serial position effect
○ Remember words at beginning and end of list, not in the middle
- Primacy effect:
○ Ppl remember first 5 words in list
○ Bc first words are best rehearsed and sent to LTM
- Recency effect:
○ Ppl remember last 5 words in list
○ Bc these are last words presented. They are fresh and in STM
- This supports STM store and rehearsal of MSM

Clive Wearing:
- His elaborative rehearsal is not working- cannot make new memory
- Suggests STM and LTM are 2 separate stores & there is a process moving one to the other

Brain Scan Research:
- Researchers found:
○ Pre frontal cortex is active during STM NOT LTM
○ Hippocampus active during LTM NOT STM
- Proves diff memory stores

Bad:

Clive Wearing:
• Playing piano = procedural memory
• MSM says there is ONE of each store (STM, LTM…)
• Wearing shows there is more than one store

Over-simplified:
- Model is over-simplified
- Evidence suggests many STM and LTM stores
○ Eg LTM = episodic, procedural, semantic

KF:
- Suffered brain damage after motorbike accident
- Forgetting of auditory info > visual stimuli
- Brain damage only in phonological loop
- Supports multiple stores within STM

Question 4

What is each store in the MSM

Answer 4

Unitary - there is one store of each
