An Introduction To The Visual System

Building on the successful formula of the first edition, Martin Tovée offers a concise but detailed account of how the visual system is organised and functions to produce visual perception. He takes his readers from first principles; the structure and function of the eye and what happens when light enters, to how we see and process images, recognise patterns and faces, and through to the most recent discoveries in molecular genetics and brain imaging, and how they have uncovered a host of new advances in our understanding of how visual information is processed within the brain. Incorporating new material throughout, including almost 50 new images, every chapter has been updated to include the latest research, and culminates in helpful key points, which summarise the lessons learnt. This book is an invaluable course text for students within the fields of psychology, neuroscience, biology and physiology.

In recent years there has been a host of new advances in our understanding of how we see. From molecular genetics come details of the photopigments and the molecular causes of disorders like colour blindness. In-depth analysis has shown how a cell converts light into a neural signal using the photopigments. Traditional techniques of microelectrode recording along with new techniques of functional imaging - such as PET scans - have made it possible to understand how visual information is processed in the brain. This processing results in the single coherent perception of the world we see in our 'mind's eye'. An Introduction to the Visual System provides a concise, but detailed, overview of this field. It is clearly written, and each chapter ends with a helpful 'key points' section. It is ideal for anyone studying visual perception, from the second year of an undergraduate course onwards.

If you've ever been tricked by an optical illusion, you'll have some idea about just how clever the relationship between your eyes and your brain is. This book leads one through the intricacies of the subject and demystifying how we see.

Vision is our most dominant sense, from which we derive most of our information about the world. From the light that enters the eye and the processing in the brain that follows we can sense where things are, how they move and what they are. The first edition of Visual Perception took a refreshingly different approach to perception, starting from the function that vision serves for an active observer in a three-dimensional environment. This fully revised and expanded new edition continues this approach in contrast to the traditional textbook treatment of vision as a catalogue of phenomena. Following a general introduction to the main theoretical approaches, the authors discuss the historical basis of our current knowledge. Placing the study of vision in its historical context, they look at how our ideas have been shaped by art, optics, biology and philosophy as well as psychology. Visual optics and the neurophysiology of vision are also described. The core of the book covers the perception of location, motion and object recognition. There is a new chapter on representation and vision, including a section on the perception of computer generated images. This readable, accessible and truly relevant introduction to the world of perception aims to elicit both independent thought and further study. It will be welcomed by students of visual perception and those with a general interest in the mysteries of vision.

'Vision and the Visual System' offers students, teachers and researchers a rigorous, yet accessible account of how the brain analyses the visual scene. Schiller and Tehovnik describe key aspects of visual perception such as colour, motion, pattern and depth while explaining the relationship between eye movements and neural structures in the brain.

Vision is our most dominant sense. From the light that enters our eyes to the complex cognititve provesses that follow, we derive most of our information about what thigns are, where they are and how they move from our vision.

Does the world appear the same to everyone? Does what we know determine what we see? Why do we see the world as we do? Vision is our most dominant sense. From the light that enters our eyes to the complex cognitive processes that follow, we derive most of our information about what things are, where they are, and how they move from our vision. Visual Perception takes a refreshingly different approach to this enigmatic sense. From the function that vision serves for an active observer, to the history of visual perception itself the third edition has been extensively revised, updated and expanded, while still preserving the essential features of historical context, neurophysiology and independent thought that made the earlier editions so engaging. Covering the perception of location, motion, object recognition and with up-to-date information on the workings of the visual brain, the 3rd edition looks at how our ideas have been shaped, not just by psychology, but by art, optics, biology and philosophy. The emphasis on understanding vision as a basis for action in the real world has also been expanded to cover seeing representations of all sorts, whether they are pictures or computer-generated displays. The 3rd Edition of Visual Perception is a readable, accessible and truly relevant introduction to the world of perception and will be welcomed by students of visual perception as well as anyone with a general interest in the mysteries and wonder of vision.
