Multi store model of memory

Question 1

What is the multi store model of memory (MSM)

Answer 1

Linear model of how info flows in terms of memory (LTM, STM and sensory register)
First memory model
Suggested by Atkinson and Shiffrin

Question 2

How does the sensory register work

Answer 2

Info enters through 5 senses
Info decays with no attention
Attention moves info to STM

Potentially unlimited capacity
Short duration - 250ms

Question 3

How does STM work in the MSM

Answer 3

Info can be forgotten due to displacement
Maintenance rehearsal keeps info in STM
Consistent maintenance rehearsal moves info to LTM

5-9 info capacity
18-30 second duration
Encoded acoustically

Question 4

How does LTM work in MSM

Answer 4

Info rehearsed infrequently to keep in LTM
Info is retrieved from LTM to STM through cues

Unlimited capacity
Unlimited duration
Encoded semantically

Question 5

Evaluate Atkinson and Shiffrin’s MSM

Answer 5

Research to support MSM - Peterson and Peterson - duration of STM

Patient KF bike accident - Could encode visually but not acoustically

Research to support - Brain scans show LTM and STM occupy different brain areas - LTM = Hippocampus
STM = Prefrontal cortex

Nomothetic vs ideographic
