Laurence Harris – författare

It has become apparent that vision is not a passive process working on the retinal image like a film to record a perfect copy as the perception. Instead, higher-level cognitive processes such as expectancies, memories and experience play a critical, almost overriding role. This book is a review and summary of the tremendous advances that have been made in recent years on the effect of attention on visual perception. The book will appeal to vision scientists as well as to people 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 this a very useful and broad-ranging volume.

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) flow. There are sections devoted to vestibular processing, eye movement processing and processing during brightness perception. The final section covers levels of processing in spatial vision. All scientists and graduate students working in vision will be interested in this book as well as people involved in using visual processes in computer animations, display design or the sensory systems of machines.
