Review "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 Product Description 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.
