This book investigates the cognitive and neural mechanisms underlying mental imagery to determine whether it functions as a distinct form of representation or merely a byproduct of propositional thought. The authors, prominent researchers in cognitive neuroscience, synthesize decades of experimental data and neuroimaging studies to argue that mental imagery is a functional, quasi-pictorial process. They present a comprehensive framework that bridges the gap between behavioral psychology and brain-based evidence, challenging reductionist views that dismiss imagery as epiphenomenal.

Experts recognize this work as a foundational text for understanding the cognitive architecture of the human mind. Readers frequently note the academic density of the prose, which serves as a rigorous reference for students and researchers in cognitive science.
