That is more remembering things and not for 'quick thinking' per se - OP's goal. There is a very interesting book on the concept of 'Memory Palace' (on which 'artofmemory.com' is based on): Moonwalking with Einstein: The Art and Science of Remembering Everything http://www.amazon.com/Moonwalking-Einstein-Science-Rememberi...

These techniques can also be applied to "concepts", not just objects and words. Reduced latency of human access, e.g. placing related concepts "nearby" in human memory, has similar benefits as database indexes which colocate related data. Some data visualizations help with associative thinking. "Quick" thinking may involve navigation around a high-dimensional conceptual space, which could be simplified as projections onto 2D images which can be stored in a memory palace. Flatland is a classic essay on the 2D/3D boundary.

Another way of approaching the question would be to look at people who can have "quick conversations", e.g. longtime team members. There's a shared body of experience and shared vocabulary for complex concepts, addressable by shorthand.

Memory and emotion go hand-in-hand with perception.
