Multi Store Model

Question 1

MSM

Answer 1

Developed by Atkinson and Shiffin

Question 2

Sensory register

Answer 2

Encoding - modality specific
Duration - less than one second
Capacity - large

Question 3

STM

Answer 3

Encoding - acoustic
Duration - 18-30 seconds
Capacity 7+/-2

Question 4

LTM

Answer 4

Encoding - semantic
Duration - infinite
Capacity - unlimited

Question 5

Describe the MSM

Answer 5

Separate unitary stores
Linear model (Sensory register - STM - LTM)
Maintenance rehearsal

Question 6

A03 - oversimplification of the LTM - patient HM

Answer 6

Patient HM could acquire new procedural memories, such as mirror-drawing, which relies on motor skills.
This is because he only had lost his episodic memory.

Question 7

A03 - Patient HM and CW - limitation of MSM

Answer 7

Both patients show separation between the STM and the LTM
Their immediate memory span was relatively intact, but they were unable to form new episodic long-term memories
Suggests STM and LTM are separate systems
Shows that memory can’t be unitary

Question 8

A03 - brain scans - supportive

Answer 8

Beardsley (1997) found that the prefrontal cortex is active during short-term tasks, such as decision making
Squire (1992) found that the hippocampus is active when long-term memories are used
