This book presents a collection of articles reflecting state-of-the-art research in visual perception, specifically concentrating on neural correlates of perception. Each section addresses one of the main topics in vision research today. Part 2: Fundamentals of Awareness, Multi-Sensory Integration and High-Order Perception covers topics from filling-in to visual awareness to crossmodal interactions. A variety of methodological approaches are represented, including single-neuron recordings, fMRI and optical imaging, psychophysics, eye movement characterization and computational modelling. The contributions will provide the reader with a valuable perspective on the current status of vision research, and more importantly, with critical insight into future research directions and the discoveries yet to come. · Provides a detailed breakdown of the neural and psychophysical bases of Perception · Presents never-before-published original discoveries · Includes multiple full-color illustrations

This landmark volume brings together the work of the world's leading researchers in sublimated perception. This compilation marks a fundamental shift in the current study of subliminal effects: No longer in question is the notion that perception without awareness occurs. Now, the emphasis is on elucidating the parameters of subliminal effects and understanding the conditions under which stimuli perceived without awareness significantly influence affect, cognition, and behavior. PERCEPTION WITHOUT AWARENESS firmly establishes subliminal perception within the mainstream of psychological science. Well represented here are the two main research branches that have emerged: One directly investigates the nature of subliminal effects; the other uses subliminal techniques as tools for investigating psychological phenomena such as hypnosis, dreaming, repression, social judgment and inference, psychopathology, and symptom formation. Broadly grouped into three main sections, the contributed chapters explore * The cognitive perspective--including implicit memory and implicit perception, the measurement of unconscious perceptual processes, and methods for revealing unconscious processes * The clinical perspective--exploring the cognitive and dynamic aspects of subliminal perception, memory, and consciousness; direct recovery of subliminal stimuli; and validation of subliminal psychodynamic activation * The social perspective--discussing subliminal mere-exposure effects, affect and social perception, and the role of subliminality in social psychology Timely and thought-provoking, PERCEPTION WITHOUT AWARENESS is sure to be of enormous interest to all psychoanalytic clinicians and scholars, as well as cognitive, clinical, and social psychologists whose work touches upon issues relating to psychopathology, perception, cognition, and memory.

The present volume was assembled in honor of Professor Alan Cowey FRS, and attempts to embrace his wide range of research interests in visual neuroscience. It is divided into four sections. The first contains a group of papers dealing with different fundamental aspects of the visual system, including the control and monitoring of eye movements. The second is concerned with the functional organization of cortical visual areas and their role in visual perception and visually guided action. The third addresses issues concerning color and motion perception, along with broader questions of visual attention; and the effects of selective brain damage on these different aspects of visual experience. The fourth and final section of the volume deals explicitly with questions relating to visual awareness, with particular emphasis on 'blindsight', a topic on which Alan Cowey has worked extensively in recent years, both in humans and in monkeys.

Several popular theories of consciousness propose that conscious representations entail deeper or more complex forms of information processing. We question this view and show that unconscious perception is more powerful than previously thought. In the first set of experiments we explore brightness perception, one of the most fundamental aspects of vision. We show, using a combination of metacontrast masking and priming, that the simultaneous brightness contrast (SBC) illusion occurs without awareness. These results demonstrate that our visual systems account for stimulus context in brightness perception for stimuli that we are unaware of. Our results further suggest that SBC occurs early during visual processing, likely within the initial feedforward sweep. We then extend these observations and demonstrate that activation of complex stimulus-response mappings also occurs unconsciously, when stimulus processing times are adequate. One of our key claims these results support is that some of the apparent differences between unconscious and conscious vision are due to differences in information processing times, as opposed to consciousness. We also show, using TMS, that unconscious shape priming requires primary visual cortex at specific temporal phases of processing. Because the later temporal phase of processing suppression has been proposed to interfere with feedback activity, our results further suggest that feedback is also essential for unconscious processing and may not necessarily be a signature of conscious vision. Together our results demonstrate that complex visual information can also be represented unconsciously, and suggest that conscious and unconscious vision use similar neural pathways and processes.

"Most of the research on the epistemology of perception has focused on visual perception. This is hardly surprising given that most of our knowledge about the world is largely attributable to our visual experiences. The present volume is the first to instead focus on the epistemology of non-visual perception - hearing, touch, taste, and cross-sensory experiences. Drawing on recent empirical studies of emotion, perception, and decision-making, it breaks new ground on discussions of whether or not perceptual experience can yield justified beliefs and how to characterize those beliefs. The Epistemology of Non-Visual Perception explores questions not only related to traditional sensory perception, but also to proprioceptive, interoceptive, multisensory, and event perception, expanding traditional notions of the influence that conscious non-visual experience has on human behavior and rationality. Contributors investigate the role that emotions play in decision-making and agential perception and what this means for justifications of belief and knowledge. They analyze the notion that some sensory experiences, like touch, have epistemic privilege over others, as well as perception's relationship to introspection, and the relationship between action perception and belief. Other essays engage with topics in aesthetics and the philosophy of art, exploring the role that artworks can play in providing us with perceptional knowledge of emotions. The essays collected here, written by top researchers in their respective fields, offer perspectives from a wide range of philosophical disciplines and will appeal to scholars interested in philosophy of mind, epistemology, philosophical psychology, among others."--Publisher description.

The thesis investigates the evidence for perception without awareness in both patients and normal individuals. This is examined by considering which types of visual material might be subject to such processing and at what level (perceptual or semantic) the processing appears to occur. The evidence is discussed in relation to working memory and long term memory processes. One previous study which suggested that perception without awareness can occur in neglect patients at a semantic level was the burning house task of Marshall and Halligan (1988). Results from two replications of this study with patients and normals do not unambiguously support this interpretation. Further experiments, employing a repetition priming technique, suggest that meaningful visual material can be processed to a perceptual level in young individuals. However, a comparable task presenting similar, but novel and meaningless, material produced no evidence of such processing in either normal individuals or neglect patients. The results of further experiments employing conceptual priming tasks produced evidence for semantic implicit processing in both neglect patients and normals. The evidence from these experiments is discussed in relation to initial, direct long term memory processing occurring for all incoming information. Results of a further set of experiments, employing proverbs, support this theory and suggest that the strength by which material is represented in long term memory directly affect observed levels of perception without awareness. The data resulting from all these experiments are discussed at length in relation to working memory and long term memory processing.
