The Perception of Illusory Contours is a complete and comprehensive volume on one of the most important phenomena in modern perception research. An illusory contour is a demonstration in which people perceive edges, surfaces, objects and colors that have no physical reality. The international group of distinguished researchers which comprise the contributors to the volume present new theoretical interpretations and data in addition to reviewing the extensive literature on this topic. The volume begins with an introduction to the research on and theories behind illusory contours and their applications to other areas of perception, cognitive science and art. The collection also features English language translations of the seminal papers by Schumann, Ehrenstein, and Kanizsa, the scientists who originally discovered and investigated the phenomenon. The Perception of Illusory Contours contains the most comprehensive set of illusory contour figures ever assembled. The volume is a most significant reference work in an area of research at the critical intersection of perception, cognitive science, visual neurophysiology, and artificial intelligence.

From Fragments to Objects

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!

The theory of visual perception that Irvin Rock develops and supports in this book with numerous original experiments, views perception as the outcome of a process of unconscious inference, problem solving, and the building of structural descriptions of the external world.

Written by a group of developmental scientists, this book debates cognitive achievements in early infancy from a multidisciplinary perspective. The editors combine knowledge from different areas of infant development research to present an integrated view of the cognitive abilities emerging in early infancy. The chapters are arranged in a sequence that best conveys to the reader the line of reasoning that emerged during the development of this book. The book opens with chapters dealing with fundamental and general aspects of cognitive development, sweeps through the specific theme of language acquisition, and closes by returning to general questions concerning different representation modalities.
