Perceiving In Depth Volume 1

The three-volume work Perceiving in Depth is a sequel to Binocular Vision and Stereopsis and to Seeing in Depth, both by Ian P. Howard and Brian J. Rogers. This work is much broader in scope than the previous books and includes mechanisms of depth perception by all senses, including aural, electrosensory organs, and the somatosensory system. Volume 1 reviews sensory coding, psychophysical and analytic procedures, and basic visual mechanisms. Volume 2 reviews stereoscopic vision. Volume 3 reviews all mechanisms of depth perception other than stereoscopic vision. The three volumes are extensively illustrated and referenced and provide the most detailed review of all aspects of perceiving the three-dimensional world.Volume 1 starts with a review of the history of visual science from the ancient Greeks to the early 20th century with special attention devoted to the discovery of the principles of perspective and stereoscopic vision. The first chapter also contains an account of early visual display systems, such as panoramas and peepshows, and the development of stereoscopes and stereophotography. A chapter on the psychophysical and analytic procedures used in investigations of depth perception is followed by a chapter on sensory coding and the geometry of visual space. An account of the structure and physiology of the primate visual system proceeds from the eye through the LGN to the visual cortex and higher visual centers. This is followed by a review of the evolution of visual systems and of the development of the mammalian visual system in the embryonic and post-natal periods, with an emphasis on experience-dependent neural plasticity. An account of the development of perceptual functions, especially depth perception, is followed by a review of the effects of early visual deprivation during the critical period of neural plasticity on amblyopia and other defects in depth perception. Volume 1 ends with accounts of the accommodation mechanism of the human eye and vergence eye movements.

Volume 2 addresses stereoscopic vision. It starts with the physiology of stereoscopic mechanisms. It then deals with binocular rivalry, binocular summation, and interocular transfer. A review of how images are brought into binocular register is followed by a review of stimulus tokens used to detect disparities. Cyclopean effects, such as cyclopean illusions, cyclopean motion, texture segregation, and binocular direction are reviewed. Factors that influence stereoacuity are discussed. Two chapters describe how stimuli in distinct depth planes produce contrast effects, and affect motion perception and whiteness perception. The Pulfrich stereomotion effect and perception of motion in depth are reviewed. The volume ends with a review of applications of stereoscopy.

The three volumes are extensively illustrated and referenced and provide the most detailed review of all aspects of perceiving the three-dimensional world. Volume 3 addresses all depth-perception mechanisms other than stereopsis. The book starts with an account of monocular cues to depth, including accommodation, vergence eye movements, perspective, interposition, shading, and motion parallax. A chapter on constancies in depth perception, such as the ability to perceive the sizes and shapes of objects as they move or rotate in depth, is followed by a chapter on the ways in which depth cues interact. The next chapter reviews sources of information, such as changing disparity, image looming, and vergence eye movements, used in the perception of objects moving in depth. Various pathologies of depth perception, including visual neglect, stereoanomalies, and albanism are reviewed. Visual depth-perception mechanisms through the animal kingdom are described, starting with insects and progressing through crustaceans, fish, amphibians, reptiles, birds, and mammals. The chapter includes a discussion of how stereoscopic vision may have evolved. The next chapter describes how visual depth perception is used to guide reaching movements of the hand, avoiding obstacles, and walking to a distant object. The next three chapters review non-visual mechanisms of depth perception. Auditory mechanisms include auditory localization, echolocation in bats and marine mammals, and the lateral-line system of fish. Some fish emit electric discharges and then use electric sense organs to detect distortions of the electric field produced by nearby objects. Some beetles and snakes use heat-sensitive sense organs to detect sources of heat. The volume ends with a discussion of mechanisms used by animals to navigate to a distant site. Ants find their way back to the nest by using landmarks and by integrating their walking movements. Several animals navigate by the stars or by polarized sunlight. It seems that animals in several phyla navigate by detecting the Earths magnetic field.

The three volumes are extensively illustrated and referenced and provide the most detailed review of all aspects of perceiving the three-dimensional world. Volume 2 addresses stereoscopic vision in cats and primates, including humans. It begins with an account of the physiology of stereoscopic mechanisms. It then deals with binocular rivalry, binocular summation, binocular masking, and the interocular transfer of visual effects, such as the motion aftereffect and visual learning. The geometry of the region in binocular space that creates fused images (the horopter) is discussed in some detail. Objects outside the horopter produce images with binocular disparities that are used for stereoscopic vision. Two chapters provide accounts of mechanisms that bring the images into binocular register and of stimulus tokens that are used to detect binocular disparities. Another chapter discusses cyclopean effects, such as cyclopean illusions, cyclopean motion, and binocular direction that are seen only with binocular vision. Stereoacuity is the smallest depth interval that can be detected. Methods of measuring stereoacuity and factors that influence it are discussed. Two chapters deal with the various types of binocular disparity and the role of each type in stereoscopic vision. Another chapter deals with visual effects, such as figure perception, motion perception, and whiteness perception that are affected by the relative distances of stimuli. The spatiotemporal aspects of stereoscopic vision, including the Pulfrich stereomotion effect are reviewed. The volume ends with an account of techniques used to create stereoscopic displays and of the applications of stereoscopy.

Originally published in 1977, the chapters in this volume derive from a conference on Perceiving, Acting and Knowing held by the Center for Research in Human Learning at the University of Minnesota in 1973. The volume was intended to appeal, not just to the specialist or the novice, but to anyone sufficiently interested in psychology to have obtained a sense of its history at the time. Through these essays the authors express a collective attitude that a careful scrutiny of the fundamental tenets of contemporary psychology may be needed. In some essays specific faults in the foundations of an area are discussed, and suggestions are made for remedying them. In other essays the authors flirt with more radical solutions, namely, beginning from new foundations altogether. Although the authors do not present a monolithic viewpoint, a careful reading of all their essays under one cover reveals a glimpse of a new framework by which theory and research may be guided.

In his first book, Dedrick ushers the reader into a space where only his deepest musings reside. From poems of love, anger, and spirituality - he makes sure to have something for everyone to grasp. In an endeavor to give life to the phrase "my life is an open book," join Dedrick as he explores his inner self, and find out just how deep he is in Depth Perception.

Beginning with his doctoral dissertation in 1950 which introduced the study of event perception and the application of vector analysis to perception, Gunnar Johansson has been a seminal figure in the field of perception. His work on biomechanical motion in the 1970s challenged conventional notions and stimulated great interest among experimental psychologists and students of machine vision. In 1989 Johansson published his latest theoretical synthesis, the optic sphere theory, an innovative conceptualization that goes beyond his earlier proposals. This volume presents -- for the first time -- an extensive precis of the out-of-print classic 1950 monograph prepared by Johansson. It also includes a representative set of Johansson's important publications produced over the ensuing four decades. These papers served as the springboard for a set of original essays by a distinguished group of North American and European scientists. Part critical commentary, part elaboration, and part seeking new directions, the entire collection makes for a singularly rich treatment of the perception of objects and events.

This volume combines the classical fields of perception research with the major theoretical attitudes of today's research, distinguishing between experience- versus performance-related approaches, transformational versus interactional approaches, and approaches that rely on the processing versus discovery of information. Perception is separated into two parts. The first part deals with basic processes and mechanisms, and discusses early vision and later, yet still basic, vision. The second covers complex achievements with accounts of perceptual constancies and the perception of patterns, objects, events, and actions.
