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.

The Spiral After-Effect discusses the spiral after-effect of apparent movement. It aims to bring a body of research literature into some compact form for the convenience of students and clinicians in particular, and experimentalists in general. It seeks to outline the main areas of interest in the study of this intriguing illusion and to examine the influence of selected psychophysical, program, and subject factors on its incidence and duration. It also provides a few suggestions for future research. The book begins with an introduction and historical review of studies on the after-effect of apparent movement. Separate chapters then cover stimulus variables and their influence on the incidence and duration of the after-effect; program variables relevant to the incidence and duration of the illusion; the influence of selected observer variables on the incidence and duration of the after-effect; and theoretical explanations of the after-effect. The appendix provides an abstract of the main experiments, findings, and conclusions of the pre-eminent figure in the field of motion aftereffects Dr. G. A. Wohlgemuth who, working between 1905 and 1909, brought together the existing literature up to the period and summarized what was largely nineteenth-century work.

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.

Put the power of Expressions to work in your animations with controls and efficiencies impossible to achieve with traditional keyframing techniques. No programming skills are required. Foundation concepts and skills orient the new designer and serve as a handy reference to the experienced one. Basics of creating expressions, variables, commands, and expression helpers precede the leap into javascript and math essentials for more advanced expressions that include randomness, physical simularions and 3D. Full color illustrations display the scripts and the resulting effects, pickwhip techniques, and sequential animations. Downloadable companion files include Quicktime movies of the demo animations, and AE project files that permit you to examine the Expressions. Extensive notes are provided to aid you in implementing the extensive library of Expressions available for your use on Adobe LiveDocs.

From August 24-29, 1980 the international "Symposium on the Study of Motion Perception; Recent Developments and Applications", sponsored by NATO and organized by the editors of this book, was held in Veldhoven, the Netherlands. The meeting was attended by about eighty scholars, including psychologists, neurologists, physicists and other scientists, from fourteen different countries. During the symposium some fifty research papers were presented and a series of tutorial review papers were read and discussed. The research presentations have been published in a special issue of the international journal of psychonomics "Acta Psychologica" (Vol. 48, 1981). The present book is a compilation of the tutorial papers. The tutorials were arranged around early versions of the chapters now appearing in this book. The long discussions at the Veldhoven tutorial sessions resulted in extensive revisions of the texts prior to this publication. Unfortunately this led to a delay in publication, but we feel that this was justified by a greater depth of understanding which, in our opinion, has significantly increased the quality of the book. As they now stand, the chapters cover most of the issues relevant to the study of motion perception. Also they clearly reflect the intensive exchange of knowledge that took place during the symposium. As such we think that this book can be used both as an advanced text for students and scientists alike and as a comprehensive reference source.
