Sounds an awful lot like model based reasoning which has had applications in AI since (at least) Winograd's SHRDLU project in 1970: <>. The aforementioned web page focuses on the natural language aspect of the system. I reverse engineered SHRDLU as part of an AI course in grad studies. It develops plans for moving blocks around by applying a theorem prover to a formal representation of its world, so in quite a literal sense it fits Richard's definition (though not at all in the same league as the way humans do similar things).
