The episodic buffer was not a part of Baddley’s original model. It was added to the model 25 years later. It is seen as a place to temporarily integrate information gathered from the phonological loop, visuo-spatial sketchpad, and long-term memory. The episodic buffer is controlled by the central executive, yet it transfers information into and out of the long term store. The addition of the episodic buffer allowed a clearer connection to be made between working memory and long-term memory.
