This book investigates the cognitive and neurological mechanisms that create the wide spectrum of human facial recognition ability, ranging from super recognisers to those with prosopagnosia. Karen Lander, a researcher in cognitive psychology, synthesizes current experimental data and clinical findings to explain why individual differences in face processing occur. The text explores how genetic factors, developmental experiences, and brain structure influence the efficiency of the human visual system. By examining the extremes of the recognition spectrum, the author provides a framework for understanding the standard human capacity for social identification.

Experts in cognitive psychology recognize this work as a clear synthesis of current research on face processing. Readers frequently note the accessible yet rigorous nature of the prose, making it a useful resource for students and professionals interested in visual cognition.
