Atkinson & Shriffin:
two process model of memory - showed how info flowed through the 2 stores of short term & long term memory - assuming the existence of sensory memory that precedes STM - termed Multi store model
regarded stores as structural components of model - proposed number of control processes such as ATTENTION, CODING & REHEARSAL which operate in conjunction w/stores - info moves through 3 stores under control of various cognitive processes
STM decays rapidly + limited capacity - Miller = hold between 5 & 9 items at 1 time - chunking of info lead to increase in STM capacity - if info not rehearsed within 15-30 secs info lost
model suggests we receive info from environment through 5 senses - automatically stored in sensory register up to 2 secs - large capacity
Coding + rehearsal determine fate of info
capacity of LTM = infinite/ all types of encoding -- STM =acoustic encoding
