Available in PDF, EPUB and Kindle. Book excerpt: Visual Psychophysics and Physiology: A Volume Dedicated to Lorrin Riggs illustrates a particular approach to the study of vision. It also celebrates Lorrin Riggs' retirement from formal teaching duties. During his teaching career Riggs advised and directed about fifty doctoral and postdoctoral students, many of whom wrote the chapters that make up this volume. The book is organized into six parts. Part 1 explains the approach to the study of vision, thus providing the philosophical theme for the chapters that follow. Part 2 on physiological mechanisms presents examples of comparative and physiological investigations. Part 3 on sensitivity and adaptation examines new research that bears directly upon the classical problems of visual psychophysics. Here, there is an initial concern with measurement, visual sensitivity, scaling, and adaptation. Part 4 discusses research on color vision while Part 5 on acuity, contrast, and movement considers some of the factors that contribute to these perceptions. Part 6 deals with applications of visual science to other disciplines. Specific examples are given that link visual research with ophthalmology, child development, and the investigation of cognitive variables such as meaning, activation, and so forth.
