The multi store model of memory was proposed by Atkinson and Shiffrin (1972). It suggests
that our memory can be understood in terms of different stores.
Receives incoming info from the senses.
Modality Specific info from each sensory system is encoded in the corresponding
The duration is very short
Sperling (1966) demonstrated that the capacity is surprisingly large.
Receives info from the Sensory Memory
Uses rehearsal to transfer info to the LTM
Miller found that the capacity is limited to 7 ± 2 items
Retrieval from STM happens using a serial exhaustive search every item in memory is
checked, even after the item being looked for is identified.
Has the greatest duration and capacity
Forgetting still occurs
Encoding is semantic stored on the basis of meaning
Retrieval from LTM may use several mechanisms, such as a hierarchy as proposed by
Collins and Quillian (1976) and various kinds of cues such as context and state.
It has made an important contribution It is over simplified and fails to reflect the
to memory research complexity of human memory
Enabled psychologists to construct Doesn't explain why info changes in coding
testable models of memory from one memory store to another
Provided foundation for later work Doesn't take into account the type of info taken
