Evaluation: The multi-store model of memory

Question 1

State the 1st evaluation point of the multi-store model of memory.

Answer 1

Supporting evidence
- Controlled lab studies on capacity, duration & coding supports existence of a separate STM & LTM store

• Beardsly (1997)
• Found prefrontal cortex active during STM but not LTM
• Squire et al
• Hippocampus active in LTM

Question 2

State the 2nd evaluation point of the multi-store model of memory.

Answer 2

Case study

• Patient called HM = Hippocampus removed to reduce epilepsy
• Could not form new LTM’s

There this provides support as:

• Patient unable to transfer information from STM - LTM
• Before surgery was able to retrieve information

Question 3

State the 3rd evaluation point of the multi-store model of memory.

Answer 3

Model is too simple
- Research does not support that they are ‘Single unitary’ stores
- There are a number of qualitatively different binds of LTM
e,g Maintenance rehearsal does not explain LTM episodic memory but does in semantic memory
