Outline and evaluate the multi-store model of memory (12 marks)
Atkinson and Shiffrin’s multi-store model suggests that long-term memory and
short-term memory are like hypothetical stores of information. They believe
that memory has three stages; sensory memory, short-term and long-term
memory. Information first enters sensory memory where it undergoes encoding
and then transfers to short-term memory. Once there it’s rehearsed or verbally
repeated in order to undergo further encoding before being transferred to
long-term memory, otherwise it will decay.
A big aspect of the model was rehearsal; information can’t reach long-term
memory unless it’s rehearsed. The more it’s rehearsed, the longer the memory
will be as the trace becomes stronger.
The model has been criticised as lacking ecological validity because the
evidence for the model comes mainly from laboratory based experiments using
meaningless verbal data.
It’s also criticised as being simplistic; the model assumes that both short and
long term memory consist of individual stores made up of one component each,
but research into the…
