Born in 1838, Mach was a pioneer in the field of physics, having even made an impression on Einstein in his younger life who credited him with being the "Philosophical forerunner of relativity theory." His name is also associated with the speed of sound (as in traveling at Mach "insert-number-here") as well as the Doppler effect. Throughout his career, he was particularly interested in the biological and sensory relationship to physics and science, and naturally, this interest expanded to that of (...) the world of psychological perception and physiological psychology as well as philosophy. The Analysis of Sensations is about just that, the nature of the relationship of physics and the physical sciences to psychological phenomena of sense and perception. It's a fascinating read for anyone looking to expand their knowledge of how the two sides of the same coin meld harmoniously. (shrink)

This book collects some of the most exciting pioneering work in perceptual and cognitive psychology. The authors' quantitative approach to the study of mental images and their representation is clearly depicted in this invaluable volume of research which presents, interprets, evaluates, and extends their work. The selections are preceded by a thorough review of the history of their experiments, and all of the articles have been updated with reviews of the current literature. The book's first part focuses on mental rotation; (...) the second includes other, more complex transformations and sequences of transformations. A third part describes work on rotational transformations in the context of the perceptual illusion of &"apparent motion.&" Roger N. Shepard is Professor of Psychology, Stanford University. Lynn A.
