- theoretical explanation of memory in terms of ‘stores’. Developed by Atkinson & Shiffrin in 1968
- proposes that memory is split into three separate stores: Sensory, Short-term and Long-term memory, Each with different durations and capacities and linked as information must pass through each store to be remembered in the long term.
- First widely accepted models of memory and although now outdated it has lead to many new discoveries.
- One way to show the existence of different stores is to link STM and LTM to specific areas of the brain.
- Research has found that the prefrontal cortex is active when working on a STM task (Beardsley, 1997) whereas the hippocampus is involved when LTM is engaged (Squire et al,1992).
