multi store model

Question 1

Supporting research evidence

Answer 1

P-A strength of MSM is that it is supported by research studies showing that STM and LTM are qualitatively different
E-For example, Baddeley found we tend to mix up words that sound similar when we’re using our STM’s
E-But we mix up words with similar meaning when using LTM’s, clearly showing that coding in STM and LTM are different as STM is acoustic and LTM is semantic.
L-This supports the MSM’s view that these two memory stores are separate and independent.

Question 2

There is more than one type of STM

Answer 2

P-Evidence from people suffering a clinical condition, amnesia shows that stm is not a unitary store
E-For example, Shallice and Warrington studies a patient with amnesia known as KF and found KF’s stm for digits was very poor when they read them out loud to him but his recall was much better when he was able to read the digits to himself.
L- The unitary STM is a limitation of MSM because research shows that at the very least there must be one short term store to process visual information and another to process auditory information

Question 3

There is more than one type of rehearsal

Answer 3

P-According to the msm, that the more information rehearsed the more likely you are to transfer it to LTM
E-However, Craik and Watkins found that this prediction is wrong, what really matters about rehearsal is the type
E-They discovered two types of rehearsal, maintenance rehearsal is described in the msm, but this does not transfer information into ltm it just maintains it in stm. Elaborative rehearsal is needed for long term storage. This occurs when you link the information to your existing knowledge or you think about what it means
L-This is a serious limitation of the msm because it is another research finding that cannot be explained by the model/
