This book presents the basic concepts of classical psychophysics, derived from Gustav Fechner, as seen from the perspective of modern measurement theory. The theoretical discussion is elucidated with examples and numerous problems, and solutions to one-quarter of the problems are provided in the text.

Part I: Background
1: Ordinal Measurement
2: Extensive Measurement
3: Functional Equations
Part II: Theory
4: Fechner's Psychophysics
5: Models of Discrimination
6: Psychometric Functions
7: Further Topics on Psychometric Functions
8: Sensitivity Functions - Weber's Law
9: Psychophysical Methods
10: Signal Detection Theory
11: Psychophysics with Several Variables or Channels
12: Homogenity Laws
13: Scaling and the Measurement of Sensation
14: Meaningful Psychophysical Laws

"Falmagne says much that is useful and important. Not only does this book provide a solid grounding in the formalization of psychophysical theory, but its author also gives thoughtful commentary about many issues, from the implicit principles governing measurement in physical science to the various criticisms about the meaning of sensory scales....For novice and seasoned students of psychophysics alike, this book is well worth the effort."--Contemporary Psychology

"Excellent in providing formalisms and formal models of basic psychophysical results, and can be recommended to any experienced investigator in the field . . . Can provide a great service to the psychophysical community by introducing a level of mathematical sophistication generally associated with theory construction in physics and chemistry." --Mathematical Reviews

"...An excellent, innovative text..." --Journal of Mathematical Psychology

"It is a pleasure to see a book like this involving the applications of mathematical sciences to psychological events. Such application to biological events has certainly produced vast rewards in biophysics, and it is high time such progress is made in areas of psychological behavior and mental sciences. This book, intended as a textbook for a two semester graduate course, does this job excellently." --Research Communications in Psychology, Psychiatry and Behavior
