Perception of Pixelated Images covers the increasing use of these images in everyday life as communication, socialization, and commerce increasingly rely on technology. The literature in this book is dispersed across a wide group of disciplines, from perception and psychology to neuroscience, computer science, engineering, and consumer science. The book summarizes the research to date, answering such questions as, What are the spatial and temporal limits of perceptual discrimination of pixelated images?, What are the optimal conditions for maximizing information extracted from pixelated images?, and How does the method of pixelation compromise or assist perception? Integrates research from psychology, neuroscience, computer science, and engineering Explains how the process of perception works for pixelated images Identifies what assists and hinders perception, including the method of pixelation Discusses the limits of perception of pixelated images

A rigorous case for the primacy of mind in nature, from philosophy to neuroscience, psychology and physics. The Idea of the World offers a grounded alternative to the frenzy of unrestrained abstractions and unexamined assumptions in philosophy and science today. This book examines what can be learned about the nature of reality based on conceptual parsimony, straightforward logic and empirical evidence from fields as diverse as physics and neuroscience. It compiles an overarching case for idealism - the notion that reality is essentially mental - from ten original articles the author has previously published in leading academic journals. The case begins with an exposition of the logical fallacies and internal contradictions of the reigning physicalist ontology and its popular alternatives, such as bottom-up panpsychism. It then advances a compelling formulation of idealism that elegantly makes sense of - and reconciles - classical and quantum worlds. The main objections to idealism are systematically refuted and empirical evidence is reviewed that corroborates the formulation presented here. The book closes with an analysis of the hidden psychological motivations behind mainstream physicalism and the implications of idealism for the way we relate to the world.

Our contact with the world is through perception, and therefore the study of the process is of obvious importance and signi?cance. For much of its long history, the study of perception has been con?ned to natural- tic observation. Nonetheless, the phenomena considered worthy of note have not been those that nurture our survival—the veridical features of perception—but the oddities or departures from the common and c- monplace accuracies of perception. With the move from the natural world to the laboratory the oddities of perception multiplied, and they received ever more detailed scrutiny. My general intention is to examine the interpretations of the perc- tual process and its errors throughout history. The emphasis on errors of perception might appear to be a narrow approach, but in fact it enc- passes virtually all perceptual research from the ancients until the present. The constancies of perception have been taken for granted whereas - partures from constancies (errors or illusions) have fostered fascination.

Ecomedia: Key Issues is a comprehensive textbook introducing the burgeoning field of ecomedia studies to provide an overview of the interface between environmental issues and the media globally. Linking the world of media production, distribution, and consumption to environmental understandings, the book addresses ecological meanings encoded in media texts, the environmental impacts of media production, and the relationships between media and cultural perceptions of the environment. Each chapter introduces a distinct type of media, addressing it in a theoretical overview before engaging with specific case studies. In this way, the book provides an accessible introduction to each form of media as well as a sophisticated analysis of relevant cases. The book includes contributions from a combination of new voices and well-established media scholars from across the globe who examine the basic concepts and key issues of ecomedia studies. The concepts of "frames," "flow", and "convergence" structure a dynamic collection divided into three parts. The first part addresses traditional visual texts, such as comics, photography, and film. The second part of the book addresses traditional broadcast media, such as radio, and television, and the third part looks at new media, such as advertising, video games, the internet, and digital renderings of scientific data. In its breadth and scope, Ecomedia: Key Issues presents a unique survey of rich scholarship at the confluence of Media Studies and Environmental Studies. The book is written in an engaging and accessible style, with each chapter including case studies, discussion questions and suggestions for further reading.

The field of perception is devoted to explaining the operation of the senses and the experiences and behaviors resulting from stimulation of the senses. Perceptual processes such as recognizing faces, seeing color, hearing music, and feeling pain represent the actions of complex mechanisms, yet we usually do them easily. The Encyclopedia of Perception presents a comprehensive overview of the field of perception through authoritative essays written by leading researchers and theoreticians in psychology, the cognitive sciences, neuroscience, and medical disciplines. It presents two parallel and interacting approaches: the psychophysical, or determining the relationship between stimuli in the environment and perception, and the physiological, or locating the biological systems responsible for perception. Are there any processes not associated with perception? Surely there are, but the pervasiveness of perception is truly impressive, and the phenomena of perception and its mechanisms are what this encyclopedia is about. Key Features Contains 16 pages of color illustration and photography to accompany the entries Offers a varied and broad list of topics, including basic research as well as methodologies, theoretical approaches, and real-world applications of perceptual research Emphasizes human perception but includes ample research because of its importance in its own right and because of what this research tells us about human perception Written by recognized experts from many disciplines but for an audience with no previous background in perception—students and members of the general public alike Key Themes Action Attention Audition Chemical Senses Cognition and Perception Computers and Perception Consciousness Disorders of Perception Illusory Perceptions Individual Differences (Human) and Comparative (Across Species; Not Including Ageing, Disorders, and Perceptual Development) Methods Perceptual Development/Experience Philosophical Approaches Physiological Processes Sense Interaction Skin and Body Senses Theoretical Approaches Visual Perception

Visual masking is a technique used in cognitive research to understand pre-conscious processes (priming, for example), consciousness, visual limits, and perception issues associated with psychopathology. This book is a short format review of research using visual masking: how it has been used, and what these experiments have discovered.Topics covered include concepts, varieties, and theories of masking; masking and microgenetic mechanisms and stagesof visual processing; psychopharmacological and genetic factors in masking, and more. Provides succinct information about the widely dispersed masking studies and points out some new trends in masking research Reviews transcranial magnetic stimulation (TMS) as an alternative to the traditional psychophysical masking methods Comments on the methodological pitfalls hidden in the practice of masking, helping to improve the quality of future research where masking is used as a tool Informs readers about recent developments in theoretical attempts to understand masking
