Beyond words: nonverbal communication
Read the passage and take notes on the main points. 

Nonverbal communication is any kind of communication that takes place without the use of words. It can refer to facial expressions such as smiling or frowning; it can refer to movements of the head such as nodding the head to show agreement or shaking it to show disagreement; it can refer to hand gestures such as offering the hand to shake in greeting or waving the hand to say "hello" or "good-bye." Nonverbal communication can also refer to a whole host of other ways of communicating without words inasmuch as nonverbal communication is limited only by  exclusion: it is any type of communication without words. Communication is verbal if words are used; it is nonverbal if words are not used.
