ABSTRACT
Human communication is a symphony of continuously altering states. Utterances are rapidly created, fading as quickly as they are produced; body odors change with varying emotional states and with differing levels of stress; communicators shift their postures, wave their arms, cock their heads, and generally move in synchrony to the sounds that they produce. Most likely, you have watched people on television with the sound turned off. Such images graphically illustrate that the entire body, not just the vocal channel, is used in communication.
