chapter  4
Approaches to the Psychology of Visual Perception
Pages 8

In Part I of this book we were concerned with the workings of the eyes and those parts of the brain that handle information received from them. At several points, we saw how this physiological knowledge could explain quite specific aspects of our conscious awareness of the world. We can explain in terms of the physiology of the retina why we cannot read a book in dim light or see colours at night, or why it takes only three primaries to reproduce any colour. At the same time, however, we saw that the relationship between most of our visual experience and the functioning of the brain remains largely unknown.
