Book Description
The Perception of Multiple Objects describes a neurally inspired computational model of two-dimensional object recognition and spatial attention that can explain many characteristics of human visual perception. The model, called MORSEL (named for its ability to perform Multiple Object Recognition and attentional Selection), is unique in providing a broad and unified explanation for a wide range of experimental psychological data on visual perception and attention. Although it draws on existing theoretical perspectives from cognitive psychology, it is a fully mechanistic account, not just a functional-level theory. MORSEL has been trained to recognize letters and words in various positions on its "retina." Following training, it can also recognize several items at once, subject to capacity limitations. The model makes predictions about what sorts of information the visual system can process in parallel and what sorts must be processed serially. Through simulation experiments, chiefly in letter and word perception, MORSEL has been shown to account for a variety of psychological phenomena, including perceptual errors that arise when several items appear simultaneously in the visual field, facilitatory effects of context and redundant information, attentional phenomena, visual search performance, and behaviors exhibited by neurological patients with acquired dyslexia.

Book Description
Multisensory Perception: From Laboratory to Clinic surveys the current state of knowledge on multisensory processes, synthesizing information from diverse streams of research and defining hypotheses and questions to direct future work. Reflecting the nature of the field, the book is interdisciplinary, comprising the findings and views of writers with diverse backgrounds and varied methods, including psychophysical, neuroanatomical, neurophysiological and neuroimaging approaches. Sections cover basic principles, specific interactions between the senses, the topic of crossmodal correspondences between particular sensory attributes, the related topic of synesthesia, and the clinic. - Offers a comprehensive, up-to-date overview of the current state of knowledge on multisensory processes - Coverage includes basic principles, specific interactions between the senses, crossmodal correspondences and the clinical aspects of multisensory processes - Includes psychophysical, neuroanatomical, neurophysiological and neuroimaging approaches

Book Description
"Marmodoro's monograph engages with Aristotle's views on a philosophically challenging question regarding perception, which has been central in the history of philosophy and is very much the focus of current debates in a number of philosophical and psychological disciplines: How do we become perceptually aware of objects in the world? Despite the significance of the question, the ways in which ancient philosophers have addressed it have only just begun to be be explored. There is a great wealth of insight on this question to be found in Aristotle, regarding our ability to perceive items in our environment, which he develops through his very demanding metaphysics, and Marmodo explores these insights in depth here. Aristotle's attempts at accounting for our awareness of complex perceptual content were highly original, drawing on and building on the metaphysics he has developed elsewhere in his works, but have not been adequately explored to date"--

Book Description
Studying the Perception-Action System as a Model System for Understanding Development, Volume 55, the latest release in the Advances in Child Development and Behavior series, includes chapters that highlight some of the most recent research in the field of development of the perception-action system, with an overarching theme of addressing how the development of the perception-action system is a useful model for understanding both typical and atypical development. Chapters in this latest release include discussions of Perception and Action, Exploration and Selection, and the Acquisition of Skills in Infancy, The Development of Object Fitting: The Dynamics of Spatial Coordination, Developmental Pathways of Change in Perceptual-Motor Learning, Timing Is Almost Everything: How Children Perceive and Act on Dynamic Affordances, Vision, Whole Body Coordinations, and the Development of Throwing, Action Errors: A Window into the Early Development of Perception-Action System, Are Different Actions Mediated by Distinct Systems of Knowledge in Infancy and Childhood?, Sensory-Motor Development as a Precursor to Cognition, and A Perception-Action Approach to Those with Developmental Coordination Disorder. - Compiles contributions from leaders in research on the perception-action system - Contains theoretical contributions in the field of developmental psychology - Fills major gap in the literature on this topic

Book Description
From a barrage of photons, we readily and effortlessly recognize the faces of our friends, and the familiar objects and scenes around us. However, these tasks cannot be simple for our visual systems--faces are all extremely similar as visual patterns, and objects look quite different when viewed from different viewpoints. How do our visual systems solve these problems? The contributors to this volume seek to answer this question by exploring how analytic and holistic processes contribute to our perception of faces, objects, and scenes. The role of parts and wholes in perception has been studied for a century, beginning with the debate between Structuralists, who championed the role of elements, and Gestalt psychologists, who argued that the whole was different from the sum of its parts. This is the first volume to focus on the current state of the debate on parts versus wholes as it exists in the field of visual perception by bringing together the views of the leading researchers. Too frequently, researchers work in only one domain, so they are unaware of the ways in which holistic and analytic processing are defined in different areas. The contributors to this volume ask what analytic and holistic processes are like; whether they contribute differently to the perception of faces, objects, and scenes; whether different cognitive and neural mechanisms code holistic and analytic information; whether a single, universal system can be sufficient for visual-information processing, and whether our subjective experience of holistic perception might be nothing more than a compelling illusion. The result is a snapshot of the current thinking on how the processing of wholes and parts contributes to our remarkable ability to recognize faces, objects, and scenes, and an illustration of the diverse conceptions of analytic and holistic processing that currently coexist, and the variety of approaches that have been brought to bear on the issues.

Book Description
Because of the ease with which we perceive, many people see perception as something that "just happens." However, even seemingly simple perceptual experiences involve complex underlying mechanisms, which are often hidden from our conscious experience. These mechanisms are being investigated by researchers and theorists in fields such as psychology, cognitive science, neuroscience, computer science, and philosophy. A few examples of the questions posed by these investigations are, What do infants perceive? How does perception develop? What do perceptual disorders reveal about normal functioning? How can information from one sense, such as hearing, be affected by information from another sense, such as vision? How is the information from all of our senses combined to result in our perception of a coherent environment? What are some practical outcomes of basic research in perception? These are just a few of the questions this encyclopedia will consider, as it presents a comprehensive overview of the field of perception for students, researchers, and professionals in psychology, the cognitive sciences, neuroscience, and related medical disciplines such as neurology and ophthalmology.
