Visual Perception explores fundamental topics underlying the field of visual perception, including the perception of brightness and color, the physics of light, and the optics of the eye. Although the text leans heavily on physical and physiological concepts, explanations of the relevant physics and physiology are considered. This book is organized into 16 chapters and begins with an overview of the relationship between information assimilation and the physiology of the visual system based on data gathered both in physiological and perceptual experiments. More specifically, this text discusses the nature of the human perceptual system in terms of the kinds of information that are assimilated from the world, and how this selection of information is governed by the structure of receptors and the neural circuits that are connected to them. The relationships between symbols and their corresponding physical and physiological variables are also examined. Finally, the book addresses the presence of strong lateral inhibition in the visual system and how it fits the concept of evolution. This book is aimed at undergraduate and graduate students, regardless of their academic backgrounds.

Cutting-edge research on the visual cognition of scenes, covering issues that include spatial vision, context, emotion, attention, memory, and neural mechanisms underlying scene representation. For many years, researchers have studied visual recognition with objects—single, clean, clear, and isolated objects, presented to subjects at the center of the screen. In our real environment, however, objects do not appear so neatly. Our visual world is a stimulating scenery mess; fragments, colors, occlusions, motions, eye movements, context, and distraction all affect perception. In this volume, pioneering researchers address the visual cognition of scenes from neuroimaging, psychology, modeling, electrophysiology, and computer vision perspectives. Building on past research—and accepting the challenge of applying what we have learned from the study of object recognition to the visual cognition of scenes—these leading scholars consider issues of spatial vision, context, rapid perception, emotion, attention, memory, and the neural mechanisms underlying scene representation. Taken together, their contributions offer a snapshot of our current knowledge of how we understand scenes and the visual world around us. Contributors Elissa M.

A radically integrative account of visual perception, grounded in neuroscience but drawing on insights from philosophy and psychology. How do we gain access to things as they are? Although we routinely take our self-made pictures to be veridical representations of reality, in actuality we choose (albeit unwittingly) or construct what we see. By movements of the eyes, the direction of our gaze, we create meaning. In Brain and the Gaze, Jan Lauwereyns offers a novel reformulation of perception and its neural underpinnings, focusing on the active nature of perception. In his investigation of active perception and its brain mechanisms, Lauwereyns offers the gaze as the principal paradigm for perception. In a radically integrative account, grounded in neuroscience but drawing on insights from philosophy and psychology, he discusses the dynamic and constrained nature of perception; the complex information processing at the level of the retina; the active nature of vision; the intensive nature of representations; the gaze of others as visual stimulus; and the intentionality of vision and consciousness. An engaging point of entry to the cognitive neuroscience of perception, written for neuroscientists but illuminated by insights from thinkers ranging from William James to Slavoj Žižek, Brain and the Gaze will give new impetus to research and theory in the field.

In the late-1980s, visual cognition was a small subfield of cognitive psychology, and the standard texts mainly discussed just iconic memory in their sections on visual cognition. In the subsequent two decades, and especially very recently, many remarkable new aspects of the processing of brief visual stimuli have been discovered -- change blindness, repetition blindness, the attentional blink, newly-discovered properties of visual short-term memory and of the face recognition system, the influence of reentrant processing on visual perception, and the surprisingly intimate relationships between eyeblinks and visual cognition. This volume provides up-to-date tutorial reviews of these many new developments in the study of visual cognition written by the leaders in the discipline, providing an incisive and comprehensive survey of research in this dynamic field.

Sensory perception has been the subject of scientific and philosophical inquiry for centuries, and it is well accepted that it is closely related to the workings of the brain. However, the precise relationship between brain activity and sensory perception remains elusive. Visual illusions are useful tools to study the workings of the brain. Motion- induce blindness (MIB), one such illusion, renders an unchanging visual target intermittently invisible when surrounded by an array of moving distractors. Here I explore the relationship between brain activity and sensory perception by recording the activity of single neurons in the brain of awake-behaving monkeys, while they experience motion-induced blindness. Monkeys were trained to report, using a lever press, whether they saw a small visual target appear or disappear. Recordings were made from primary visual cortex (V1) and frontal-eye field (FEF), while monkeys reported their perceptual state during MIB. Results show that activity in VI is related primarily to stimulus parameters, regardless of the perceptual state of the monkeys, whereas FEF shows the opposite behavior, with activity correlated to perceptual state of the monkey regardless of stimulus parameters. Based on the response properties of V1 cells I propose a conceptual model by which different brain areas might contribute to the perceptual disappearance in this illusion. The neuronal responses recorded from FEF are, thus far, the temporally earliest known to correlate with perceptual state when it is dissociated from the physical stimulus, and will need to be taken into consideration by any theory of perceptual consciousness.

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.
