We have presented a theory of mechanism description and simulation which is based on tenets and processes we hypothesize to be applicable to other aspects of human cognition. We feel the theory of cause-effect representation is sound and expressive for a wide variety of mechanisms, and that it bears significance as a theory of human cause-effect knowledge representation. Our next specific goals are three fold: (1) to make the acquisition of new mechanism patterns interactive, having the model prompt the user, and verify that the user s use of the representation coincides with the model's notions of semantic well-forkedness, (2) to study the processes of mechanisms abstraction, and (3) to apply the existing CSA plan synthesizer to the task of mechanisms invention, involving the simulator in a debugging loop.
