ABSTRACT
You do not need to know much about the underlying physiol-ogy to understand the results of our research on human tutor-ing or the ideas underlying the building of our Intelligent Tutoring System, but a certain minimal familiarity with the physiology of the baroreceptor reflex, particularly the concepts and the language used to describe it, is helpful to understand fully the tutoring and the tutorial dialogues that are discussed here. It is also helpful to understand the problem being solved by the students. This chapter provides the minimal necessary background in physiology. If you find this chapter difficult, you can, of course, skip ahead to the next chapter, and then come back here later if you need more information about the underlying physiology to understand the tutoring dialogues.
