multi-store model

Question 1

What does the Multi-Store Model suggest?

Answer 1

It suggests that memory is made up of three stores, linked by processing.

Question 2

What is the purpose of the Multi-Store Model?

Answer 2

To show how information moves through the memory system.

Question 3

What are the key components of the multi-store model?

Answer 3

• Sensory Register
• Short Term Memory (STM)
  -Long Term Memory (LTM)

Question 4

What is the first component that an environmental stimulus passes through?

Answer 4

Sensory Register

Question 5

What is the sensory register?

Answer 5

-the first component of the MSM that environmental stimulus passes through

Question 6

What is the duration of the sensory register?

Answer 6

Less than half a second

Question 7

Which of the three components of the MSM is made up of multiple registers?

Answer 7

Sensory Register is made up of multiple registers and coding in each store is modality-specific

Question 8

What is the capacity of the sensory register?

Answer 8

Very high

Question 9

What store does information pass into after the Sensory Register?

Answer 9

STM

Question 10

How does information move if you pay attention?

Answer 10

From the Sensory Register, to the STM

Question 11

How does information move from Sensory Register to STM?

Answer 11

Attention

Question 12

What is the duration of STM?

Answer 12

Approximately 18 seconds

Question 13

What is the capacity of STM?

Answer 13

Approximately 5-9 pieces of information

Question 14

How does information code in STM?

Answer 14

Acoustically

Question 15

What happens if the STM exceeds its capacity?

Answer 15

Old information is displaced

Question 16

What happens to a piece of information if it doesnt move into LTM and duration runs out?

Answer 16

It decays

Question 17

How does information stay in STM?

Answer 17

-there must be maintenance rehearsal. If it is prolonged, it passes into LTM.

Question 18

What is maintenance rehearsal? What does it do?

Answer 18

• repeating information in your head over and over
  -keeps information in STM

Question 19

What is prolonged rehearsal? What does it do?

Answer 19

-rehearsing information over a long period of time
-moves info from STM to LTM

Question 20

How does information move from STM to LTM?

Answer 20

Prolonged rehearsal

Question 21

How is information coded in LTM?

Answer 21

Mainly semantically

Question 22

What is the duration thought to be for LTM?

Answer 22

Lifetime

Question 23

What is the capacity thought to be for LTM?

Answer 23

Infinite

Question 24

What must happen in order for information from LTM to be recalled?

Answer 24

-must be retrieved which moves information from LTM to STM

Question 25

How does information move from LTM to STM?

Answer 25

retrieval

Question 26

What are the limitations of the Multi-Store Model?

Answer 26

-MSM may have oversimplified the memory stores
-believes that the amount of rehearsal is important rather than the type.
-the use of artificial materials to support it

Question 27

What research suggests that the Multi Store Model may have oversimplified the memory stores? How?

Answer 27

-Shalice and Warrington
-found that an amnesia patient, KF, had poor recall for digits when they were read out loud to him but his recall was much better when he read
digits to himself.
-According to the MSM, he should not be able to do one of these, causing issues with STM being just one thing.

Question 28

What research supports the Multi Store Model?

Answer 28

Glanzer and Cunitz found participants remembered words from the start (a primary effect) and end of a list (a recency effect) but were less good at recalling words in the middle. This supports idea of more than one memory store- the start words are in the LTM due to rehearsal, and the end words are in the STM, while middle words are displaced from the STM by end words.
