In our daily lives, in our memories and fantasies, our mental worlds overflow with faces. But what do we really know about this most remarkable feature of the human body? Why do we have faces at all, and brains that are good at reading them? What do our looks say – and not say – about our personalities? And perhaps the most compelling question of all: Why are we attracted to some faces more than others? 'In Your Face' is an engaging and authoritative tour of the science of facial beauty and face perception. David Perrett, the pre-eminent scholar in the field, reveals and interprets the most remarkable findings and in the process demolishes many popular myths, setting the record straight on what neuroscience and evolutionary psychology are teaching us about beauty. The record is more surprising and often more unsettling than you might think.
