This collection celebrates the 150th anniversary of Fechner's book on Psychophysics (originally published ten years after his epiphany of Oct. 22, 1850). Topics include modern assessments of the problems with which Fechner wrestled. Also included are more general discussions of psychophysical methodology, psychophysical theory, and how these two things can be useful in areas not normally associated with psychophysics. Furthermore, these works provide an entrée into Fechner’s ideas, which is perhaps more accessible than his seminal work itself.

Even in the age of Internet, when information and knowledge are just a click away, few probably know what is psychophysics and what is it for. Psychophysics can be romantically defined as the science that measures the soul, namely the sensory soul. Psychophysics estimates the sensibility and looks for the threshold, that ephemeral limit between the sensed and the not sensed, the perceived and the not perceived, the seen and the not seen. It is a challenging task, since this limit is like a butterfly twirling over a flowery meadow, and psychophysics is the tool aimed at measuring as exactly as possible the height of its flight. At the boundary between experimental psychology and sensory neuroscience, psychophysics is not confined within a theoretical framework, but has great importance also in the clinical setting: audiologists, ophthalmologists, optometrists, orthoptists as well as neuropsychiatrists make use of psychophysics in many of their diagnostic protocols. This book aims at describing the principles of this discipline in a simple yet rigorous form, so as to make psychophysics understandable to the broad audience of non-psychophysicists. And, why not, even to reveal its hidden charm.

Psychophysics and Experimental Phenomenology of Pattern Cognition examines the cognitive transformations that underly this cognitive system, and the specialized subsystems for processing these transformations. Sections cover symmetry cognition, contour perception, and geometric illusion. Weight sensation is also discussed, as are repetitive and dot patterns. Incorporating the fields of psychophysics and experimental phenomenology, pattern cognition is examined from both the physical and mental sensory perspective, providing a comprehensive view of this cognitive system. Examines the cognitive transformations underlying pattern cognition, and the specialized subsystems for processing transformations Provides an interdisciplinary psychophysics and experimental phenomenology perspective Features sections on cover symmetry cognition, contour perception, and geometric illusion Describes weight sensation, and repetitive and dot patterns.

Color vision is considered a microcosm of the visual science. Special physiological and psychological processes make this scientific topic an intriguing and complex research field that can aggregates around molecular biologists, neurophysiologists, physicists, psychophysicists and cognitive neuroscientists. Our purpose is to present the frontier knowledge of this area of visual science, showing, in the end, the future prospects of application and basic studies of color perception.

A Primer of Signal Detection Theory is being reprinted to fill the gap in literature on Signal Detection Theory--a theory that is still important in psychology, hearing, vision, audiology, and related subjects. This book is intended to present the methods of Signal Detection Theory to a person with a basic mathematical background. It assumes knowledge only of elementary algebra and elementary statistics. Symbols and terminology are kept at a basic level so that the eventual and hoped for transfer to a more advanced text will be accomplished as easily as possible. Intended for undergraduate students at an introductory level, the book is divided into two sections. The first part introduces the basic ideas of detection theory and its fundamental measures. Its aim is to enable the reader to be able to understand and compute these measures. It concludes with a detailed analysis of a typical experiment and a discussion of some of the problems which can arise for the potential user of detection theory. The second section considers three more advanced topics: threshold theory, the extension of detection theory, and an examination of Thurstonian scaling procedures.

Our lives are informed by perceptual and cognitive processes at all levels, from instrumental learning to metaphorical discourse to memorial representation. Yet, historically, these two branches of experimental psychology, perception and cognition, have developed separately using independent methods of experimentation and analysis. This volume is motivated by the assumption that a fundamental integration of the two fields is fruitful methodologically and indispensable theoretically. It explores how the notion of psychophysics aligned with cognitive processes shapes the study of perception and
