Nonverbal Communication

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.(46)__________.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.(47)_________.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,(48)_________.Therefore,we carefully avoid this,except in suitable situations.

Researchers(49)________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,(50)_________;it can be a challenge to the professor’s authority;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 just dull if it were all done with words.
