Multi-Store Model of Memory

Question 1

Who proposed the MSM?

Answer 1

Atkinson and Shiffrin, argues that info flows in a linear sequence.

Question 2

What are the features of the sensory register?

Answer 2

capacity: very large
duration: 250 milliseconds
coding: modality specific

Question 3

What are the features of STM?

Answer 3

capacity: 7+/-2 (5-9 items)
duration: 18-30 seconds
coding: accoustic

Question 4

What are the features of LTM?

Answer 4

capacity: unlimited
duration: potentially a lifetime
coding: semantic

Question 5

How does the case of HM support the MSM?

Answer 5

• suffered from epilepsy, had to remove his hippocampus
• HM’s procedural memory remained functional, but he lost the ability to form new declarative memories

Question 6

How does KF’s case study challenge the MSM?

Answer 6

• suffered brain damage as a result of a motorcycle accident
• STM for digits were poor when read aloud (auditory info affected)
• better recall when being read himself (visual info unaffected)
