Who developed the idea that short-term memories get "filed away" in three different areas of the brain: a visuospatial area, a phonological loop for auditory memories, and an episodic buffer for multimodal memories with story-lines?

Hermann Ebbinghaus

Explanation:

is his theory propose that, memory fades because of the passage of time. Information is not available for later retrieval as time goes by and memory, as well as memory strength, wears away. When an individual has a new knowledge, a neurochemical "memory trace" is created. However, as time goes on, this trace slowly disintegrates. Continually practicing information is believed to be a major factor counteracting this temporal decline
