phonological loop: temporary store of verbal information, holds and rehearses words that are being considered.
the phonological loop is encoded acoustically.
The visuo-spatial sketchpad has two components: an inner scribe which processes visual details and an outer scribe which deals with spatial relations.
Episodic buffer: allows us to integrate information from different sources into one coherent story.
long term memory stores large amounts of information over long periods of time.
the visuospatial sketchpadtemporarily holds and manipulates visual and spatial tasks
the visuospatial sketchpad and the phonological loop both have a limited capacity.
the episodic buffer provides storage from information received from the central executive and maintain a sense of time.
the episodic buffer has a limited capacity.
The working memory model is based on the idea that we can only hold onto a small amount of information at any given moment, but it also suggests that there are separate systems within our short-term memory which allow us to process different types of information simultaneously.
The working memory model was developed by Baddeley and Hitch (1974).
Baddeley's theory states that working memory consists of four components; the central executive, the phonological loop, the visuo-spatial sketch pad and the episodic buffer.
the central executive's role is to receive information from the visuospatial sketchpad, phonological loop, perception and the long term memory then sift, sort and combine information.
(strength of working memory) Application- Working memory training has shown improvements in reading skills and maths performance.
(Weakness of working memory model) Individual differences. It does not account for variation between all people.
