BADDELEY’S WORKING MEMORY MODEL
Baddeley’s (1986, 1997) model of working memory involves three main components: a central executive, and two socalled ‘slave’ systems – the phonological loop and the visuo-spatial sketch pad. To these Baddeley (2001) has added an episodic buffer. The central executive controls attention and coordinates the slave systems; the phonological loop contains a phonological store and an articulatory control process and is responsible for inner speech; the visuo-spatial sketch pad is responsible for setting up and manipulating mental images; the episodic buffer integrates and manipulates material in working memory.
