Fascinating, profusely illustrated study explores the psychology and physiology of vision, including light and color, motion receptors, the illusion of movement, much more. Over 100 illustrations.

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.

In this richly illustrated study, the first book-length exploration of illusionistic art in the early United States, Wendy Bellion investigates Americans' experiences with material forms of visual deception and argues that encounters with illusory art shaped their understanding of knowledge, representation, and subjectivity between 1790 and 1825. Focusing on the work of the well-known Peale family and their Philadelphia Museum, as well as other Philadelphians, Bellion explores the range of illusions encountered in public spaces, from trompe l'oeil paintings and drawings at art exhibitions to ephemeral displays of phantasmagoria, "Invisible Ladies," and other spectacles of deception. Bellion reconstructs the elite and vernacular sites where such art and objects appeared and argues that early national exhibitions doubled as spaces of citizen formation. Within a post-Revolutionary culture troubled by the social and political consequences of deception, keen perception signified able citizenship. Setting illusions into dialogue with Enlightenment cultures of science, print, politics, and the senses, Citizen Spectator demonstrates that pictorial and optical illusions functioned to cultivate but also to confound discernment. Bellion reveals the equivocal nature of illusion during the early republic, mapping its changing forms and functions, and uncovers surprising links between early American art, culture, and citizenship.

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.

With the dynamic interactive Optical Illusions, each time children turn the page, lift the flaps, or pull the tabs, they'll be confronted with an even more amazing optical illusion This guide to the world of eye-tricks is fun for the entire family -- providing new and gasp-inducing moments on each page. Along with the illusions, which include a spinning thaumatrope, a stereoscope, and an entrancing 3D sculpture that "follows" you around the room, kids will welcome learning the latest theories about why illusions fool us.

If you find visual illusions fascinating Programming Visual Illusions for Everyone is a book for you. It has some background, some history and some theories about visual illusions, and it describes in some detail twelve illusions. Some are about surfaces, some are about apparent size of objects, some are about colour and some involve movement. This is only one aspect of the book. The other is to show you how you can create these effects on any computer. The book includes a brief introduction to a powerful programming language called Python. No previous experience with programming is necessary. There is also an introduction to a package called PsychoPy that makes it easy to draw on a computer screen. It is perfectly ok if you have never heard the names Python or PsychoPy before. Python is a modern and easy-to-read language, and PsychoPy takes care of all the graphical aspects of drawing on a screen and also interacting with a computer. By the way, both Python and PsychoPy are absolutely free. Is this a book about illusions or about programming? It is both!

Contains color and black-and-white illustrations of over three hundred optical illusions, each with brief, explanatory text.
