Multi store model - evaluation

Question 1

There is research supporting that STM and LTM are different
semantic, acoustic

Answer 1

• Baddeley (1966) found that we tend to mix up words that sound similar when using our STMs, but we tend to mix up words that have similar meanings when we use our LTMS
• This shows that coding in STM is acoustic and in LTM it is semantic

Question 2

The case of HM

Answer 2

HM had brain surgery to relieve his epilepsy, so his hippocampus was removed from both sides of his brain
- His LTM never improved with practice - he could not remember speaking with someone only an hour earlier
- However, his STM remains intact
- This supports the MSM because he hadn’t lost all of his memory - This suggests that there are different stores for different type of memories

Question 3

evidence suggests that there is more than one type of STM - The case of KF → Shallice and Warrington (1970)

Answer 3

shallice and Warrington (1970) studied KF = amnesia
- His STM for digits was poor when they read them out loud to him, but his recall was much better when he read the digits himself
- This suggests there must be one STM store to process visual information and another to process auditory information

Question 4

Research studies supporting the MSM use artificial materials

Answer 4

• Rs often asked Ps to recall digits, letters and sometimes words
• In everyday life we form memories related to all sorts of useful things e.g. people’s faces, names, facts etc
• This suggests that MSM lacks external validity

Question 5

It oversimplifies LTM

Answer 5

• There is a lot of research evidence that LTM is not a unitary store
• We have a LTM store for memories or facts about the world (semantic), and a different one for memories of how to ride a bike (episodic)
• This means that the LTM is limited
