The visual processes involved in moving, reaching, grasping, and playing sports are complex interactions. For example, the action of moving the head provides useful cues to help interpret the visual information. Simultaneously, vision can provide important information about the actions and their control. This becomes a reiterative process. This process, and the interactions between vision and action, are the foci of this volume. This book contains contributions from scientists who are leaders in each of the several facets of the subject. The editors consider simple types of action, such as...

This is at once a review and a summary of the tremendous advances that have been made in recent years on the effect of attention on visual perception. This broad-ranging volume will appeal to vision scientists as well as to those involved in using visual processes in computer animations, display design or the sensory systems of machines. Physiologists and neuroscientists interested in any aspect of sensory or motor processes will also find it very useful.

In this book the authors relate and discuss the idea that perceptual processes can be considered at many levels. A phenomenon that appears at one level may not be the same as a superficially similar phenomenon that appears at a different level. For example "induced motion" can be analyzed in terms of eye movements or at the retinal level or at a much higher cognitive level: how do these analyses fit together? The concept of levels also makes us think of the flow of information between levels, which leads to a consideration of the roles of top-down and bottom-up (or feed-forward, feed-back)...
