MSM theory (Atkinson and Shiffin, key theory)

Question 1

who was the proposer(s) for the multi-store model of memory?

Answer 1

Atkinson and Shiffin

Question 1

what did the MSM theory say about the sensory register? (4 key points)

Answer 1

is coded in a form appropriate to the senses
duration of less than half a second
has a very high capacity
to send to the STM, you must pay attention

Question 2

what did the MSM theory say about short-term memory? (4 key points)

Answer 2

is coded acoustically
duration of 15-30/18-30 secs without rehearsal
has a capacity of 5-9 items
to send to LTM, you must do prolonged rehearsal

Question 3

what did the MSM theory say about long-term memory? (3 key points)

Answer 3

is coded semantically
duration of up to a lifetime
has an unlimited capacity

Question 4

in the MSM study, what is maintenance rehearsal?

Answer 4

when you keep repeating information so it remains in the STM

Question 5

in the MSM theory, what does it mean when something decays?

Answer 5

we forget it

Question 6

what is the supporting evidence ‘Point’ of the MSM theory?

Answer 6

there are many studies which findings support the MSM

Question 7

what is the supporting evidence ‘Evidence’ of the MSM theory?

Answer 7

Baddeley’s study of encoding showed that we encode acoustically in the STM, but semantically in the LTM

Question 8

what is the supporting evidence ‘Explanation’ of the MSM theory?

Answer 8

this supports the MSM as it shows us that STM and LTM are independent and separate stores

Question 9

what is the supporting evidence ‘Link’ of the MSM theory?

Answer 9

as a result of being supported by valid pieces of research, the MSM is a more credible theory of types of memory

Question 10

what is the opposing evidence ‘Point’ of the MSM theory?

Answer 10

memory is more complex than the MSM suggests

Question 11

what is the opposing evidence ‘Evidence’ of the MSM theory?

Answer 11

we know from amnesia patients such as, Clive Wearing that there are different types of STM and LTM

Question 12

what is the opposing evidence ‘Explanation’ of the MSM theory?

Answer 12

the STM has separate visual and acoustic stores. Tulving found that the LTM is divided into episodic, semantic, and procedural memory stores

Question 13

what is the opposing evidence ‘Link’ of the MSM theory?

Answer 13

as the MSM does not consider that the types of memory may have more than 1 store, the model is too simplistic to explain memory
