NonverbalCommunication

All of uscommunicate with one another nonverbally,as well as with words.Most of the timewe're not aware that we're doing it.We gesture with eyebrows or a hand,meet

someone else's eyesand look away,change positions in a chair.(46)__________.However in recentyears researchers have discovered that there is a system to them almost as

consistent andunderstandable as language.

One important kindof body language is eye behavior.(47)_________.In our normal conversation,eacheye contact lasts only about a second before one or both of us look

away.When twoAmericans look,searchingly into each other's eyes,(48)_________.Therefore,wecarefully avoid this,except in suitable situations.

Researchers(49)________arenot prepared to spell out a precise vocabulary of gestures. When an Americanrubs his nose,it may mean he is disagreeing with someone or

refusing something.But there are other possible interpretations,too.Another examplE.when a studentin conversation with a professor holds the older man's eyes a little longer

than isusual,(50)_________;it can be a challenge to the professor's authority;it canbe something else entirely.The researchers look for patterns in thesituation,not for a

separate meaningfulgesture.
