Description
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.
