As I said above, few planners were intended as psychological models. Now I'll come to one that might form the basis for such a model. The idea is that when we plan, rather than building plans from scratch, we work by modifying a large memory of existing plans. This is called case-based planning.
There's an introduction and two references: the first is probably easier to follow. Introduction to Part IV of Readings in Planning, page 647. Then the article on Chef, pages 655--659. And Case-based planning: a framework for planning from experience by Hammond, in Cognitive Science volume 14 number 3 (July--September 1990). Don't read these articles if you're feeling hungry.
As above, don't go into too much detail. I don't suppose you'd ever need to write for more than twenty minutes on this one topic. So concentrate on the main points: the way in which Chef might model a person's experience-based planning, and a few example of how it mutates old plans into new.
