All of us communicate with one another nonverbally, as well as with words. Most of the time we're not aware that we're doing it. We gesture with eyebrows or a hand, meet someone else's eyes and look away, change positions in a chair. These actions we assume are occasional. However in recent years researchers have discovered that there is a system to them almost as consistent and understandable as language. One important kind of body language is eye behavior. Americans are careful about how and when they meet one another's eyes. In our normal conversation, each eye contact lasts only about a second before one or both of us look away. When two Americans look searchingly into each other's eyes, they become more intimate. Therefore, we carefully avoid this, except in suitable situations. Researchers who are engaged in the study of communication through body movement are not prepared to spell out a precise vocabulary of gestures. When an American rubs his nose, it may mean he is disagreeing with someone or refusing something. But there are other possible interpretations, too. Another example: when a student in conversation with a professor holds the older man's eyes a little longer than is usual, it can be a sign of respect; it can be something else entirely. The researchers look for patterns in the situation, not for a separate meaningful gesture. Communication between human beings would be with just dull if it were all done with words. 1.
