Multi-store Model of Memory

Question 1

Outline a strength of the multistore model

Answer 1

Evidence from brain scans show STM and LTM are separate stores. Different areas of the brain are active when performing STM tasks

Question 2

Outline another strength of the multistore model

Answer 2

Further support for MSM comes from psychological studies. Miller, Peterson, Bahrick

Question 3

Outline a limitation of the multistore model

Answer 3

Suggest only one type of STM. Shallice and Warrington proves that STM is stored differently and suggests they might be separate stores.

Question 4

Outline another limitation of the multistore model

Answer 4

MSM oversimplifies the LTM. Evidence to show LTM is not a singular unit, 1 store to remember memories, other to read, remember how to ride a bike.

Question 5

Capacity of the SR

Answer 5

Unknown, supposedly unlimited capacity, Sperling (1960)

Question 6

Capacity of the STM

Answer 6

7+/- 2 chunks of information, Miller (1946)

Question 7

Capacity of the LTM

Answer 7

Unlimited capacity

Question 8

Duration of the SR

Answer 8

Approximately 1/2 second, Sperling (1960)

Question 9

Duration of the STM

Answer 9

Approximately 18 seconds, Peterson and Peterson (1959)

Question 10

Duration of the LTM

Answer 10

Up to a Lifetime, Bahrick (1975)

Question 11

Coding of the SR

Answer 11

Via Our Senses, Modality Specific

Question 12

Coding of the STM

Answer 12

Acoustically, Baddeley (1960)

Question 13

Coding of the LTM

Answer 13

Via rehearsal, semantically, Baddeley (1960)
