Those who have become wary of popular treatments of neuroscience will be gratified by the clarity of the author’s thinking, which avoids or cuts through the simplistic reductionism and other conceptual confusions that often mar books on the brain. ... It is highly recommended to anyone with an interest in the science of conscious experience ... a category that surely includes readers of this Journal.

A fascinating introduction to synaesthesia, explaining how the trait gives insight into the way the senses are organized. Ward also delves into other sensory experiences, such as phantom limbs and sympathetic touch, in an accessible introduction to this growing research field.
NATURE, Vol 454, 31 July 2008
The Frog Who Croaked Blue reads like a fascinating novella-length essay. Ward is clearly enthralled by the topic and he has no trouble finding interesting issues to address. He explores synesthesia's potential causes, how and why the brain mixes the senses, and whether the condition might confer intellectual and even evolutionary benefits, such as a better memory. Between scientific discussions, he interweaves fascinating personal narratives from synesthetes around the world.

This very readable book provides an entertaining and informative foray into the fascinating world of synaesthesia, where words can have tastes, letters may be coloured, and the sound of a frog may indeed be blue. Jamie Ward has neatly drawn together a historical view of synaesthesia with a clear discussion of current scientific research. In seeking to explore and explain synaesthesia, the book covers such phenomena as visual experience in the blind, phantom limb pain in amputees, and drug-induced sensory experiences to form an interesting and highly enjoyable read.

Ward provides an exceedingly readable and comprehensive introduction to perhaps the most interesting area in current Psychological research. I challenge anyone not to be drawn into the fascinating world of synaesthesia, which Ward so expertly portrays. His book provides a unique perspective on the interplay between inner thought and concrete perception – and this would be of interest to anyone wishing to understand the relationship between the human mind and the world outside it.
