Multi Store Memory Model

Question 1

Describe the Sensory Register

Answer 1

Capacity - very large
Duration - 0.5 seconds (milliseconds)
Coding - modality specific
Encodes incoming environment mental stimuli through senses such as iconic, echoic and haptic.

Question 2

Describe STM.

Answer 2

Coding - acoustic
Duration - 18-30s
Capacity- 5-9 units
Attention must be paid to incoming stimuli for it to be transported into the STM.
Info is maintained within the STM through maintenance rehearsal.
If this doesn’t happen within 18-30s info decays or is displaced.

Question 3

Describe LTM.

Answer 3

Coding - semantic
Duration - unlimited
Capacity - unlimited
Info is moved into LTM through elaborative rehearsal

Question 4

How is info transported from LTM into STM?

Answer 4

Retrieval

Question 5

What has happened if you cannot remeber information stored in your LTM?

Answer 5

Interference or retrieval failure. You may just need assistance in remembering.

Question 6

Who designed the MSM?

Answer 6

Atkinson And Shiffron (1968)
