A unique aspect of this body language book is its use of comparison. Using real people in stress-free situations in photos, the authors show the same people responding to various stimuli. They also show the standards of body language, and then the adjustments to the body and face that represent deviations from those standards. Observing these changes helps you understand when youre being manipulated or being sent a disguised message, and teaches how to effectively use your own body language. 206 pgs, paperback, 2009
