Why has Atkinson and Shiffrin has been criticized?
Atkinson and Shiffrin proposed the multi-store model of memory
in 1968.
A criticism of this model was that it had been over-simplified,
and that the relationships between the short term memory and the
long term memory were more complex than it described.
Another criticism of this model was that rehearsal is far too
simple a process to account for all of the information from the
short term memory being encoded into the long term memory.
A final criticism is that is lists the short term memory as one
unit, whereas the working model of memory (proposed by Baddeley and
Hitch) spilt the short term memory up into separate sections for
each sense. E..G the phonological loop of the working model
temporarily stores verbal/sound information, and the visuospatial
sketch pad temporarily stores visual and spatial information.
