Outline the Multi-Store Model of Memory?

The multistore model of memory was proposed by Atkinson and Shiffrin and is a structural model. They proposed that memory consisted of three stores: sensory register, short-term memory (STM) and long-term memory (LTM). Information passes from store to store in a linear way.The sensory store is constantly receiving information from the environment. Most of this information receives no attention and so is lost. However, if the information that enters the sensory stores is attended to (paid attention) then this information is encoded and passes through to the short term memory (STM).Once in the STM, information (if not rehearsed), can be lost through either displacement (this is because the STM has a capacity of 7+/- 2 items) or decay (as the STM only has a duration of 0-18 seconds).If information is rehearsed, then the information can be transferred /encoded into the long term memory (LTM).The LTM can hold information for an unlimited about of time and has an unlimited capacity.When stored information is needed, it can be retrieved from the LTM back to the STM.
