As behavioral sciences develop, researchers find that the importance of speech has been overestimated. (61) Although speech is the most obvious form of communication we do use other forms of which we may be only partially aware or, in some cases, completely unaware. It is possible we are unconsciously sending messages with every action, messages that are unconsciously picked up by others and used in forming opinions. (62) These unconscious actions and reactions to them may in part account for our “feelings” and “snap judgments”.

(63) We communicate a great deal researchers have found with our bodies — by the way we move, sit. stand and what we do with our hands and heads. Imagine a few- people sitting in a waiting room: One is tapping his fingers on his briefcase, another keeps rubbing his hands together, another is biting his fingernails, still another grabs the arms of his chair tightly and one keeps running his fingers through his hair. (64) These people aren't talking but they're “saying” a lot if you know- the “body language” they're using.

Two of the most “telling” forms of behavior are driving a car and playing games. Notice a person's reaction to stress in these situations and to aggressive behavior in others.(65) Those who easily become angry, excited, passive or resentful when driving or playing may be giving insights into the inside self.
