WORKING MEMORY.
 Atkinson’s and Shiffrin’s (1968)  			 multi-store model was extremely successful in terms of the amount of research it generated.    However, as a result of this research, it became apparent that there  were a number of problems with their ideas concerning the  characteristics of short-term memory.    			 Building on this research, Baddeley and Hitch (1974)  developed an alternative model of  			 short-term memory  which they called working memory  (see fig 1).  			   			 		  									 													  											 									 Baddeley and Hitch (1974)  argue that the picture of short-term memory ( STM ) provided by the Multi-Store Model is far too simple.  According to the Multi-Store Model ,  STM holds limited amounts of information for short periods of time with  relatively little processing.  It is a unitary system. This means it is  a single system (or store) without any subsystems.  Working Memory is  not a unitary store.  									   									 										 			   								...
