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.

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.
