[SR: 1528742], Hardcover, [EAN: 9780195187168], Oxford University Press, Oxford University Press, Book, [PU: Oxford University Press], Oxford University Press, How the human visual system determines the lightness of a surface, that is, its whiteness, blackness, or grayness, remains--like vision in general--a mystery. In fact, we have not even been able to create a machine that can determine, through an artificial vision system, whether an object is white, black, or gray. Although the photoreceptors in the eye are driven by light, the light reflected by a surface does not reveal its shade of gray. Depending upon the level of illumination, a surface of any shade of gray can reflect any amount of light.In Seeing Black and White Alan Gilchrist ties together over 30 years of his own research on lightness, and presents the first comprehensive, historical review of empirical work on lightness, covering the past 150 years of research on images ranging from the simple to the complex. He also describes and analyzes the many theories of lightness--including his own--showing what each can and cannot explain. Gilchrist highlights the forgotten-yet-exciting work done in the first third of the twentieth century, describing several crucial experiments and examining the brilliant but nearly unknown work of the Hungarian gestalt theorist, Lajos Kardos. Gilchrists review also includes a survey of the pattern of lightness errors made by humans, many of which result in delightful illusions. He argues that because these errors are not random, but systematic, they are the signature of our visual software, and so provide a powerful tool that can reveal how lightness is computed. Based on this argument and the concepts of anchoring, grouping, and frames of reference, Gilchrist presents a new theoretical framework that explains an unprecedented array of lightness errors. As both the first comprehensive overview of research on lightness and the first unified presentation of Gilchrists new theoretical framework Seeing Black and White will be an invaluable resource for vision scientists, cognitive psychologists, and cognitive neuroscientists., 4682, Mental Health, 11128, Anxiety Disorders, 598622, Attention Deficit & Attention Deficit Hyperactivity Disorders, 4693, Bipolar, 282909, Codependency, 11146, Compulsive Behavior, 16311461, Dementia, 4689, Depression, 15992951, Dissociative Disorders, 282910, Dreams, 282911, Eating Disorders, 11170, Emotions, 4739, Happiness, 4694, Mood Disorders, 600620, Personality Disorders, 16311441, Post-traumatic Stress Disorder, 282839, Postpartum Depression, 4695, Schizophrenia, 10, Health, Fitness & Dieting, 1000, Subjects, 283155, Books, 11119, Psychology & Counseling, 11121, Adolescent Psychology, 11130, Applied Psychology, 11132, Child Psychology, 11149, Counseling, 11160, Creativity & Genius, 11162, Developmental Psychology, 13922612011, Evolutionary Psychology, 11172, Experimental Psychology, 11173, Forensic Psychology, 11177, History, 16311181, Medicine & Psychology, 11186, Mental Illness, 11164, Neuropsychology, 11189, Occupational & Organizational, 11192, Pathologies, 11194, Personality, 11196, Physiological Aspects, 227701, Psychiatry, 11199, Psychoanalysis, 11201, Psychopharmacology, 11203, Psychotherapy, TA & NLP, 11205, Reference, 11207, Research, 11209, Sexuality, 11223, Social Psychology & Interactions, 11229, Testing & Measurement, 10, Health, Fitness & Dieting, 1000, Subjects, 283155, Books, 573358, Cognitive Psychology, 226685, Behavioral Sciences, 75, Science & Math, 1000, Subjects, 283155, Books, 15811861, Cognitive, 6511980011, Psychology, 173514, Medical Books, 1000, Subjects, 283155, Books<
