In this video I cover the second box in the 3-box model, short-term memory, in greater detail. I explain the limited capacity of this store, George Miller's “Magical Number 7”, and how organizational encoding and chunking may appear to expand this capacity without necessarily increasing the number of “items” being held. This concept of organizing and manipulating information in this store brings us to Alan Baddeley and Graham Hitch's model of working memory. This model includes 4 main parts; a central executive, the visuospatial sketchpad, the phonological loop, and the episodic buffer (added later). This working memory model accounts for our ability to manipulate incoming information and also draw upon existing long-term memory.
