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.

A cultural history of the face in Western art, ranging from portraiture in painting and photography to film, theater, and mass media This fascinating book presents the first cultural history and anthropology of the face across centuries, continents, and media. Ranging from funerary masks and masks in drama to the figural work of contemporary artists including Cindy Sherman and Nam June Paik, renowned art historian Hans Belting emphasizes that while the face plays a critical role in human communication, it defies attempts at visual representation. Belting divides his book into three parts: faces as masks of the self, portraiture as a constantly evolving mask in Western culture, and the fate of the face in the age of mass media. Referencing a vast array of sources, Belting's insights draw on art history, philosophy, theories of visual culture, and cognitive science. He demonstrates that Western efforts to portray the face have repeatedly failed, even with the developments of new media such as photography and film, which promise ever-greater degrees of verisimilitude. In spite of sitting at the heart of human expression, the face resists possession, and creative endeavors to capture it inevitably result in masks—hollow signifiers of the humanity they're meant to embody. From creations by Van Eyck and August Sander to works by Francis Bacon, Ingmar Bergman, and Chuck Close, Face and Mask takes a remarkable look at how, through the centuries, the physical visage has inspired and evaded artistic interpretation.

Cerebral visual impairment (also known as cortical visual impairment, or CVI) has become the most common cause of visual impairment in children in the United States and the developed world. Vision and the Brain is a unique and comprehensive sourcebook geared especially to professionals in the field of visual impairment, educators, and families who need to know more about the causes and types of CVI and the best practices for working with affected children. Expert contributors from many countries represent education, occupational therapy, orientation and mobility, ophthalmology, optometry, neuropsychology, psychology, and vision science, and include parents of children with CVI. The book provides an in-depth guide to current knowledge about brain-related vision loss in an accessible form to enable readers to recognize, understand, and assess the behavioral manifestations of damage to the visual brain and develop effective interventions based on identification of the spectrum of individual needs. Chapters are designed to help those working with children with CVI ascertain the nature and degree of visual impairment in each child, so that they can "see" and appreciate the world through the child's eyes and ensure that every child is served appropriately.

Masked priming has a short and somewhat controversial history. When used as a tool to study whether semantic processing can occur in the absence of conscious awareness, considerable debate followed, mainly about whether masked priming truly tapped unconscious processes. For research into other components of visual word processing, however - in particular, orthographic, phonological, and morphological - a general consensus about the evidence provided by masked priming results has emerged. This book contains thirteen original chapters in which these three components of visual word processing are examined using the masked priming procedure. The chapters showcase the advantages of masked priming as an alternative to more standard methods of studying language processing that require comparisons of matched items. Based on a recent conference, this book offers up-to-date research findings, and would be valuable to researchers and students of word recognition, psycholinguistics, or reading.
