Multistore Of Memory - Evaluation

Question 1

What is a strength of MSM in relation to seperate stores?

Answer 1

Research supports STM and LTM as separate stores as Glanzer and Cunitz argue in their study, words at the start of the list stored in LTM (primacy effect), words in the middle displaced from STM but not yet stored in LTM, words at the end still in STM.

Presented a distracted task to prevent rehearsal in which info in STM easily disrupted while LTM not affected

Question 2

What does the primacy effect refer to?

Answer 2

Tendency to remember items presented at beginning of a list better than those in the middle

Question 3

What’s another strength of MSM relating to coding of STM and LTM?

Answer 3

Research supports STM (acoustically) and LTM (semantically) coded differently

Baddeley argues mix up similar sounding words using STM, mix up words with similar meanings using LTM

Question 4

What’s another strength related to brain damaged patients?

Answer 4

Supports by studies of brain-damaged patients as patients with amnesia had very poor LTM but normal or almost normal STM

Difficulty remembering start and middle of list (involves LTM) yet can remember the last parts of the list that uses STM

Question 5

What’s a limitation of MSM related to different stores?

Answer 5

If sensory register has different stores, STM should have different stores aswell to store different formats of info

Amnesia studies suggest a separate store for non verbal sounds - Patient K.F (Shallice and Warrington)

Question 6

What did Patient K.F. demonstrate about short-term memory?

Answer 6

K.F. had poor short-term memory for digits read aloud but better memory for rehearsing digits himself.

suggests the existence of separate short-term stores for external and internal information.

Question 7

What’s another limitation of MSM relating to rehearsal?

Answer 7

Jenkins argues maintenance rehearsal doesnt seem necessary for store and found participants could remember material without expecting to be tested on it

Question 8

What’s another limitation of MSM relating to oversimplification?

Answer 8

Oversimplifies LTM, improbable all knowledge stored within single LTM store. Logie believes access to LTM occurs before information processed in STM for example info on how words are processed.

Question 9

What limitation did Morris highlight?

Answer 9

Doesnt really consider overall functions of memory for the individuals

Simultaneously take in more than 7 items during conversation and do it quite successfully
