Zusatztext Normal and Defective Colour Vision . . . succeeds both in strengthening our understanding of existing findings and in identifying gaps in our knowledge of chromatic processes that can be addressed in future studies. In this respect, the book as a whole is significantly more valuable than the sum of its constituent parts and is therefore a 'must' for both students and researchers in this field. Klappentext The topic of "colour vision" is one that integrates research from psychology! neuroscience! biology! opthalmology! physics! and genetics. How do we make sense of colour in the world! and how has such an ability evolved in humans? How does the brain interpret colour images? How can our genes influence the way in which we perceive colours? Do men discriminate colours differently to women? Why do some people have problems perceiving colours? John Mollon! Joel Porkorny! and Ken Knoblauch are leading authorities on this topic. Together they have brought together a stellar list of contributors! encompassing all these fields. Superbly edited and presented! this book is unique in drawing together contributors from these several fields to provide a truly interdisciplinary review of the field. Aimed at researchers in the vision sciences (including psychology and neuroscience)! this will be the definitive text on this topic for many years to come. Zusammenfassung The topic of "colour vision" is one that integrates research from psychology, neuroscience, biology, ophthalmology, physics, and genetics.
