It was my intention that the book might serve as a text or companion for an upper level
course in sensory evaluation, perhaps as a second semester offering following the introduc￾tory course in sensory evaluation. As such, it is aimed at beginning graduate students,
advanced undergraduates, and practitioners with a solid background in theory. That being
said, it is nearly impossible to write a book that is truly state of the art because the field is
so rapidly developing and new models and theories abound each year. This is especially
true in sensometrics. Rather than dwell on the latest popular theory or development, I have
focused on fundamentals, mathematical principles, and models that I suspect will stand the
test of time.
