Two dissociable updating processes in working memory dating facetherating com picture rate
One slave system, the phonological loop (PL), stores phonological information (that is, the sound of language) and prevents its decay by continuously refreshing it in a rehearsal loop.It can, for example, maintain a seven-digit telephone number for as long as one repeats the number to oneself again and again.The other slave system, the visuospatial sketchpad, stores visual and spatial information.It can be used, for example, for constructing and manipulating visual images and for representing mental maps.introduced the multicomponent model of working memory.The theory proposed a model containing three components: the central executive, the phonological loop, and the visuospatial sketchpad with the central executive functioning as a control center of sorts, directing info between the phonological and visuospatial components.Oberauer has extended Cowan's model by adding a third component, a more narrow focus of attention that holds only one chunk at a time.
In a similar vein, Cowan does not regard working memory as a separate system from long-term memory.
The episodic buffer resembles Tulving's concept of episodic memory, but it differs in that the episodic buffer is a temporary store.
have introduced the notion of "long-term working memory", which they define as a set of "retrieval structures" in long-term memory that enable seamless access to the information relevant for everyday tasks.
This feat is possible by extensive training on an encoding strategy by which the digits in a list are grouped (usually in groups of three to five) and these groups are encoded as a single unit (a chunk).
For this to succeed, participants must be able to recognize the groups as some known string of digits.
