Baddeley, A.D. (1992). Working memory. Science, 255, 556-559.
Atkinson and Shiffrin (1968) suggested working memory being necessary for learning, for remembering past information and for cognitive tasks.
The author suggests a tripartite system for working memory instead of a single unitary system with two slave systems, phonological loop and visuospatial sketch, respectively, and one central executive.
Central executive coordinates the slave systems.
Slave systems act as a dual system and one is is responsible for learning by means of visuospatial imagery while the other by rote repetition.
The phonogical loop:

The phonogical loop:
-acoustic similarity effect: similar words are more difficult to recall then dissimilar (not the meaning)
-the irrelevant speech effect: recalling a visual item presented by a irrelevant speech would be poor
-the word-length effect: people can rehearse as many words as they can in 2 seconds
-articulatory suppression: let the subject utter an irrelevant. This removes word-length effect and acoustic similarity effect, and prevents the recall of visual.
