'I thoroughly enjoyed reading this book. Each chapter was a delight, providing an overview of research and pertinent theory. As I read each successive chapter, I found myself absorbed by the material and the simple elegance with which each topic was described.' - Marjorie Collins, Murdoch University, Australia 'This book would provide an appropriate challenge for an Honours level course on consciousness, but would also be a fascinating read for all those who are interested in this intriguing and mysterious aspect of our existence. I enjoyed this book immensely.' - Elizabeth A. Boyle, Psychology Learning& Teaching (The Higher Education Academy)
