According to Baddeley, working memory is a multicomponent.  These components include: a central system (central executive) and three sub-systems (phonological loop, visuo-spatial sketch pad, and episodic buffer).  The central executive is responsible for all executive processes such as attention to relevant information, integration of information, coordinating multiple cognitive processes, as well as coordinating the sub-systems.  The phonological loop maintains a short amount of inoformation that is rehearsed.  The visuo-spatial sketch pad creates mental images (mental map).  This sub-system also has two sub-systems that include visual and spatial information.  The episodic buffer provides a connection between working memory and long term memory.  The sub-systems are fluid, but once the information makes it to long term memory it is in a crystalized system.  Information goes through the working memory by way of one of the sub-systems before making it’s way to long term memory.
