Ben, you might want to look at some modeling I recently did for my thesis.
It involves a model that uses a representation similar to schema's, which
are retrieved from memory, modified for different purposes, and eventually
proceduralized. It is described in my thesis (chapter 7), which you can
retrieve from its webpage:

http://tcw2.ppsw.rug.nl/~niels/thesis

This page also has the models themselves on it, although they are fairly
large...

Alternatively, a summary of the model is in the paper is in de proceedings
of the last cognitive science conference, although it lacks technical
details. (to be retrieved from:
