Rick, you might want to read Perspectives on Personality by Carver and Scheier Chapter 17 Self-Regulation and Feedback Control
I know you and Bill did not get along with these folks but if you are looking for a way to introduce PCT into your cognition class this will give you all the perspective you need to so without using their model.
Check it out.
Regards,
Marc
