Multi-store and working memory model Multi-store model (Atkinson's and Shiffrin's-1968) The multi-store model is a classic model of memory and is sometimes called the modal model or the duel process model. The multi-store model describes memory in terms of information flowing through a system. Information is detected by the sense organs and enters the sensory memory. If the information is attended to it enters the short term memory, information from the short term memory is transferred to the long term memory only if that information is rehearsed. However, if rehearsal doesn't occur then information is forgotten, lost from short term memory through the process of displacement or decay. A strength of the multi-store model are the model is influential because it has generated a lot of research into memory. However, a weakness of the multi-store model is it is oversimplified, in particular when it suggests that both short term and long term memory each operate in a single, uniform fashion. Working memory model (Baddeley and Hitch-1974) Baddeley and Hitch developed an alternative model of short term memory which they called working memory. They argued that the picture provided by the multi-store model is far too simple. According to the multi-store memory, short term memory holds limited amounts of information for short periods of time with relatively little processing. It is a unitary system which means it is a single system (or store) without any subsystems whereas working memory isn't a unitary store. Working memory is short term memory. Instead of all information going into one single store there are different systems for different types of information. Working memory consists of a central executive which controls and co-ordinates the operation of two subsystems; the phonological loop and the visuo-spatial sketchpad.
