The Motion Aftereffect

Motion perception lies at the heart of the scientific study of vision. The motion aftereffect (MAE) is the appearance of directional movement in a stationary object or scene after the viewer has been exposed to viusal motion in the opposite direction. For example, after one has looked at a waterfall for a period of time, the scene beside the waterfall may appear to move upward when one's gaze is transfered to it. Although the phenomenon seems simple, research has revealed copmlexities in the underlying mechanisms, and offered general lessons about how the brain processes visual information. In the 1990s alone, more than 200 papers have been published on MAE, largely inspired by improved techniques for examining brain electrophysiology and by emerging new theories of motion perception.

Motion perception lies at the heart of the scientific study of vision. The motion aftereffect (MAE), probably the best known phenomenon in the study of visual illusions, is the appearance of directional movement in a stationary object or scene after the viewer has been exposed to visual motion in the opposite direction. For example, after one has looked at a waterfall for a period of time, the scene beside the waterfall may appear to move upward when ones gaze is transferred to it. Although the phenomenon seems simple, research has revealed surprising complexities in the underlying mechanisms, and offered general lessons about how the brain processes visual information. In the last decade alone, more than 200 papers have been published on MAE, largely inspired by improved techniques for examining brain electrophysiology and by emerging new theories of motion perception. The contributors to this volume are all active researchers who have helped to shape the modern conception of MAE.

The Spiral After-Effect presents the visual phenomenon of the spiral after-effect in clinical investigations. This book explains how and under what conditions the illusion happens or can be modified. Organized into eight chapters, this book begins with an overview of the features of illusion that are similar to many of the characteristics of other movement perceptions, including vividness, velocity, and persistence. This text then examines the complex structure and the geometric function of the inducing stimulus. Other chapters consider the effects of drugs on the spiral illusion, which is rather strange when one considers the wide use of the phenomenon in patient groups who may be receiving substantial admixtures of compound for therapeutic purposes. This book discusses as well the relationship between intelligence and perception of the spiral after-effect. The final chapter deals with the conditioned after-effect. Clinical psychologists and readers who are interested in personality research will find this book useful.

After Effects for Designers teaches design students, artists, and web, graphic, and interactive designers how to design, develop, and deploy motion design projects using Adobe After Effects. Author Chris Jackson balances fundamental aspects of time-based design with related techniques, and explores the principles of animation; composition and layout; visual hierarchy; typography; cinematic storytelling; 3D modelling; compositing, and more. Each chapter contains unique, step-by-step project exercises that offer timesaving practical tips and hands-on design techniques, teaching readers how to effectively use the tools at their disposal in order to conceptualize and visualize creative solutions to their own motion design work. Readers will build professional-world examples in every chapter and, as a result, learn how to both design effectively using After Effects and practically apply these skills in client-based work. An accompanying companion website includes complete project files for the book's chapter exercises, and additional video tutorials.

The annual Computational Neuroscience Meeting (CNS) began in 1990 as a small workshop called Analysis and Modeling of Neural Systems. The goal of the workshop was to explore the boundary between neuroscience and computation. Riding on the success of several seminal papers, physicists had made "Neural Networks" fashionable, and soon the quantitative methods used in these abstract model networks started permeating the methods and ideas of experimental neuroscientists. Although experimental neurophysiological approaches provided many advances, it became increasingly evident that mathematical and computational techniques would be required to achieve a comprehensive and quantitative understanding of neural system function. “Computational Neuroscience” emerged to complement experimental neurophysiology. The Encyclopedia of Computational Neuroscience, published in conjunction with the Organization for Computational Neuroscience, will be an extensive reference work consultable by both researchers and graduate level students. It will be a dynamic, living reference, updatable and containing linkouts and multimedia content whenever relevant.
