Multistore model
Research evidence
There is a range of evidence supporting the multistore model.
The model has been useful in terms of practical application.
Explanatory power
The model can explain some important facts about memory, such as
why we remember things better if we rehearse them.
Research evidence
Shallice and warrington (1970) found that a brain damaged patient
(KF) had lost the ability to remember STM but not what he saw,
Suggesting that STM is not a unitary store.
Research suggests that too much emphasis is put on rehearsal in the
multistore model. Tulving (1967) found that there was no
difference in the participants' ability to recall words in a list, some of
which had been rehearsed beforehand and others had not.
Explanatory power
Too concerned with which memory is structured.
Memory is better seen as a number of processes.
Memory is not static as the static as the multistore suggests but
dynamic between memory and the material that goes into it.
STM and LTM are NOT unitary
The multistore model of memory includes aspects which are still
important in understanding memory.
Many psychologists have developed different theories from this basic
The working memory model
