Q

What is the duration of the LTM?

A

Forever

17
Q

What is the capacity of the LTM?

A

Unlimited

18
Q

What research shows that STM and LTM are separate?

A

Glanzer & Cunitz

19
Q

What did the Glanzer & Cunitz research show?

A

Found that words at the start and end of a word lists are more easily recalled (primacy and regency effect)
–> Suggest 1st words in LTM and last words in STM, but middle words were displaced.

20
Q

What are negatives about the multi-store model of memory?

A
  • Cognitive Tests about MSM: low mundane realism and low ecological validity
  • There are different types of LTM
  • The capacity of the STM can be changed ( age + practice)
21
Q

What did the Jacobs research show?

A

Found the recall for lists of letters and 9 for numbers
–> suggests the STM has limited capacity of 7+/-2
–> But can be improved through chunking

21
Q

What research shows the capacity of the STM?

A

Jacobs
