Why do we need two eyes? Why are all cats grey at night and appear to move faster the day? Why is the sky blue and the setting sun red? This book explains the multifaceted nature of perception, and discusses the mysteries of vision. It provides readers with experiments to help them discover optical illusions and the features of their own perception. Illusions of Seeing begins with a discussion on the essence of light and its perception to the human eye. It presents a comprehensive overview of the basic laws of human perception as well as the fundamentals of good gestalt. Subsequent chapters discuss geometric-optical illusions; the perception of form, brightness, and translucency and their interaction with each other; ambiguous perception, color vision, spatial vision. The book ends with a discussion of the perception of motion and its interaction with color, form, and spatial depth with a full chapter devoted to illusions in our everyday life. Consider this your travel guide in the marvelous world of sight, to experience a completely individual way to understand and improve your own perception. Illusions of Seeing will be of interest to psychologists, physicists, biologists, and undergraduate and graduate students within the field of cognitive psychology.

It looks so easy. Open your eyes, and immediately there is a world of objects in glorious Technicolour. It takes no time or effort - perception just happens. Or does it? As this book discusses, the more that has been discovered about the senses and the brain, the more we know that seeing, hearing, smelling, touching, and tasting depend on incredibly complicated physiology. This book is about the phenomena of perception. It covers the evolution of the sense organs, through to how perception really works and the phenomena of illusions as keys for unlocking secrets of perception.

Looks at various types of optical illusions, including distortion illusions, motion illusions, color illusions and afterimages, and impossible objects and images.

In this volume, originally published in 1978, the authors survey the historical and contemporary research literature pertaining to two-dimensional visual-geometric illusions. They bring together much of the known data, summarising and evaluating theories that have been offered to explain these phenomena. Coren and Girgus provide a new conceptual framework that suggest that visual illusions are not unitary phenomena. Within this framework, illusions do not represent a breakdown in normal perceptual processing. Rather, it is proposed that each illusion is produced by a number of mechanisms operating at different levels in the visual information processing system. The book contains an extensive collection of illusion figures. It will be essential reading for all of those concerned with vision and visual perception, since it integrates the study of illusions into the main body of psychological and perceptual theories at the time.

A specialist in visual perception, Ninio (Centre National des Recherches Scientifiques, Paris) presents many classic and new illusions, explains the underlying logic of the various types, and suggests their value for neurological and physiological research. He does not provide an index. La Science des Illusions was published in 1998 by Editions Odile Jacob. Philip has translated widely from the French, including an autobiography of Francois Jacob. c.

More than 30 images and activities in this visually stunning, elaborate pop-up book challenge readers to take a second look at the optical illusions that surround them Seeing is not always believing, and this book will challenge whether readers should believe their eyes. It contains all sorts of optical illusions including shadow play, magic mirrors, kaleidoscopes, visual vibrations, and more. Readers will be able to make patterns flicker, spin, and constantly change shape; create absurd faces in the funhouse mirrors; see beautiful abstract images through the kaleidoscope; and pull tabs and open flaps to reveal magical surprises. Plus, the book features a drawer full of additional pieces to create yet more illusions again and again.

Using the fundamentals of A Course in Miracles, Seeing Beyond Illusions walks us through a gentle dismantling of the dualistic lie of separation, freeing us from our unconscious guilt at having forsaken Source by learning to trust our divine connection to all that is. At its core, this book is about letting go of our need and urge to control, freeing ourselves to embrace forgiveness, and experience the reality of our profound connection with others. The easiest of easygoing spiritual coaches, David Cowan has a gift for synthesizing wisdom as old as Jesus and as cutting-edge as neuroscience, his writing is infused with an all-encompassing relevance that heals.

Buddhism is in many ways a visual tradition, with its well-known practices of visualization, its visual arts, its epistemological writings that discuss the act of seeing, and its literature filled with images and metaphors of light. Some Buddhist traditions are also visionary, advocating practices by which meditators seek visions that arise before their eyes. Naked Seeing investigates such practices in the context of two major esoteric traditions, the Wheel of Time (Kalacakra) and the Great Perfection (Dzogchen). Both of these experimented with sensory deprivation, and developed yogas involving long periods of dwelling in dark rooms or gazing at the open sky. These produced unusual experiences of seeing, which were used to pursue some of the classic Buddhist questions about appearances, emptiness, and the nature of reality. Along the way, these practices gave rise to provocative ideas and suggested that, rather than being apprehended through internal insight, religious truths might also be seen in the exterior world-realized through the gateway of the eyes. Christopher Hatchell presents the intellectual and literary histories of these practices, and also explores the meditative techniques and physiology that underlie their distinctive visionary experiences. The book also offers for the first time complete English translations of three major Tibetan texts on visionary practice: a Kalacakra treatise by Yumo Mikyo Dorj , The Lamp Illuminating Emptiness, a Nyingma Great Perfection work called The Tantra of the Blazing Lamps, and a B n Great Perfection work called Advice on the Six Lamps, along with a detailed commentary on this by Drugom Gyalwa Yungdrung.

Visual illusions are compelling phenomena that draw attention to the brain's capacity to construct our perceptual world. The Compendium is a collection of over 100 chapters on visual illusions, written by the illusion creators or by vision scientists who have investigated mechanisms underlying the phenomena. --

'Perception and Imaging' explains how we see and what we don't see. Relevant psychological principles will help you predict the emotional reaction of photographic images, giving you more power, control, and tools for communicating your desired message.
