The blush is a ubiquitous, but little understood, phenomenon. It involves an involuntary change in the face that can express feelings, reveal character and cause intense anxiety. Crozier provides a scholarly, yet accessible, synthesis of new research, locating blushing within the context of the 'social emotions' of embarrassment, shame and shyness.

"A leading researcher on this particular subject, Crozier has written an excellent overview of the research findings on shyness, emotions and blushing . . . this is the first study of this common phenomenon. As such it is a vital resource." - Choice
