Baddeley's Model of Working Memory consists of the following four parts: the central executive, phonological loop, episodic buffer, and visuospatial sketchpad. The semantic buffer does not exist in his model, and is the correct answer. The central executive acts like the "boss" of the other three components and directs our attention. The phonologial loop gives us the ability to temporarily hold spoken or written information in our memory through repetition; for example, you use this when trying to remember a phone number. The visuospatial sketchpad allows us to temporarily remember visuospatial information via mental images. For example, you may use this when navigating through a room to remember there is a chair to your left even when it is out of sight. Last, the episodic buffer is used to relate current experiences to memories of the past. For example, if you see a house and realize it looks similar to your childhood home.
