Working Memory
Captions available
The idea
Baddeley and Hitch described working memory as a central executive directing a phonological loop and a visuospatial sketchpad; Baddeley added an episodic buffer in two thousand.
In practice
Rehearsing a word list uses the phonological loop; picturing a route uses the sketchpad.
Where people slip
Capacity is small, often put at about seven items, and later estimates put the core limit nearer four chunks.
Your place on the trail
