Without Words: Decoding Nonverbal Signals. The motto is not to listen, but to watch in order to uncover the true motives, thoughts, and lies of colleagues, employees, and superiors. David Givens, an expert in body language, explains what hair, shoulders, hands, and even shoes reveal about the true thoughts of others. He illustrates with numerous examples from everyday business how communication science and knowledge of body signals can help read employees and business partners like an open book. The power of body language reveals, for instance, why a colleague's hand says more about what he thinks than his words do. Or why gestures are much more memorable than speeches. And how to silently fend off a curious boss.
