More than one third of the human brain is devoted the processes of seeing - vision is the main way in which we gather information about the world. This book examines vision as an 'active' process. It goes beyond most accounts of vision where the focus is on seeing, to provide an integrated account of seeing andlooking.

Written by two leading vision scientists, this book will be valuable for vision researchers and psychology students, from undergraduate level upwards.
