Sight can be so effortless, so useful, and so entertaining--the average human can distinguish several million colors; a falcon can see a fencepost from three thousand yards--that we never stop to think about how complex a process it is and how easily it can fail us. We never have as clear and complete a picture of the world around us as we think we do. The gaps between what our eyes take in and what is in our mind's eye provide the unifying theme in Bruno Breitmeyer's wide-ranging volume. In his fascinating account of the many ways that our eyes, and minds, both see and fail to see, Breitmeyer moves from cataracts and color blindness through blindsight, acquired dyslexia, and visual agnosias, including fascinating cases like the woman who did not know what she was seeing was a dog until it barked. He then uses what we've learned about the limits of our sight to illustrate the limits of our ability to mentally visualize and our ability to reason, covering everything from logical fallacies to how our motives and emotions relentlessly color the way we see the world. This book will intrigue anyone interested in how easily we can fail to capture the world around us without even realizing it.

Our visual system can process information at both conscious and unconscious levels. Understanding the factors that control whether a stimulus reaches our awareness, and the fate of those stimuli that remain at an unconscious level, are the major challenges of brain science in the new millennium. Since its publication in 1984, Visual Masking has established itself as a classic text in the field of cognitive psychology. In the years since, there have been considerable advances in the cognitive neurosciences, and a growth of interest in the topic of consciousness, and the time is ripe for a new edition of this text.Where most current approaches to the study of visual consciousness adopt a 'steady-state' view, the approach presented in this book explores its dynamic properties. This new edition uses the technique of visual masking to explore temporal aspects of conscious and unconscious processes down to a resolution in the millisecond range. The 'time slices' through conscious and unconscious vision revealed by the visual masking technique can shed light on both normal and abnormal operations in the brain. The main focus of this book is on the microgenesis of visual form and pattern perception - microgenesis referring to the processes occurring in the visual system from the time of stimulus presentation on the retinae to the time, a few hundred milliseconds later, of its registration at conscious or unconscious perceptual and behavioural levels. The book takes a highly integrative approach by presenting microgenesis within a broad context encompassing visuo-temporal phenomena, attention, and consciousness.
