Question 1

Who designed the MSM?

Answer 1

Attkinson and Shiffrin (1968,1971)

Question 2

What order does the MSM travel?

Answer 2

sensory register, STM, LTM

Question 3

Whats the sensory register? (SR)

Answer 3

recieves all stimuli from the environment.

Question 4

Whats the coding in the SR?

Answer 4

Modality-specific

Question 5

Whats the duration of the SR?

Answer 5

less than half a second

Question 6

Whats the capacity of the SR?

Answer 6

very high

Question 7

How is information coded in the STM?

Answer 7

acoustically

Question 8

Whats the duration of STM?

Answer 8

18 seconds

Question 9

Whats the capacity of STM?

Answer 9

limited, we can only remember a certain amount of things before we forget.

Question 10

Whats maintennance rehearsal?

Answer 10

The repetition of material so we can keep it in our STM, rehearsed enough it goes to LTM

Question 11

Hows LTM coded?

Answer 11

semantically

Question 12

Whats the capacity of LTM

Answer 12

practically unlimited

Question 13

Whats the duration of LTM?

Answer 13

up to a lifetime

Question 14

how to we tranfer infromation from LTM to STM?

Answer 14

retrieval

Question 15

what are the strengths of MSM?

Answer 15

• Baddeley’s (1966) study proves that STM and LTM are different

Question 16

what are the limitations of MSM?

Answer 16

• MSM may not be valid as we have to remember more meaningful information in everyday life
• evidence suggests theres more than one store in the STM, Warrington (1970) had a patient with amnesia who remembered certain things but not others.
• Elaborative rehearsal is needed for long term storage, MSM doesnt fully show how to achieve long term storage

Question 17

Whats the case of HM?

Answer 17

He underwent brain surgery where they removed his hippocampuses. in 1955 he thought it was 1953, that he was 27 when he was 31. He couldnt form any new memories after the surgery.
