Herb Simon, a collaborator with Newell at CMU, used a "memory palace" to greatly enhance recall.
I sat in on one of his courses once, a grad seminar in Cognitive Processes. He took questions for 20 minutes and then answered them in order for the rest of the lecture. They were very detailed subject matter, well over my head. I've never seen anything like it.
I was studying cog processes as an undergrad and I think I asked my professor about it and they said it was a memory palace technique.
