"The Case for Mental Imagery" offers an in depth scholarly codex for comprehending the art and science of mental representation. Although part of the Oxford Psychology Series, it's coupled with neuroscience and a rich array of case studies. In fact, I gladly found this book grounded in scientific research in comparison to other resources on the topic.
As a PhD student of Psychology with interests in imagery, thematic apperception, visualization, intuition, and the art of projection, I found this text to be highly informative. Topics covered include "behind the scenes" exploration of sensory systems, brain picturing or representations, associative memory, perception, visualization, neuroimaging; critique of topics, and much more.
