The document summarizes the Working Memory Model created by Alan Baddeley and Graham Hitch in 1974 to explain how short term memory works. The model includes a central executive system that controls cognitive processes and three slave systems - the phonological loop for verbal information, visuo-spatial sketchpad for visual and spatial information, and episodic buffer that connects information across domains. While the model helped integrate findings on short term and working memory, limitations include an unclear role of the central executive and constraints of its functions remain unknown.
