Memory: Working Memory

Working Memory is a dynamic theory of memory. Where Short-Term Memory (STM) describes the type of information stored, Working Memory describes how it is stored.

Baddeley's theories of Working Memory involve three parts: a central executive responsible for attention, a visuo-spatial sketchpad to rehearse visual images, and a phonological loop for the rehearsal of auditory stimuli.

Not all Working Memory models involve those three parts, but the commonality they share is that they view memory as an active process (especially in the short term). Items in Working Memory must be rehearsed, or they will either fade away or be replaced.
