Nonverbal communication is a process which communicators (1) use the natural features of their bodies to deliver information and express specific meaning instinctive to the other communicator. (2) The study of nonverbal communication covers three major parts: Proxemics, Kinesics and Body Language, and Paralanguage. (3) Proxemics refers that people keep a certain space with each other (4) when they communicate and the meaning it suggests. For example, Arabians like to keep close while Englishmen like to keep a certain distance. It is fun to see they are in conversation. (5) Arabians will come closer and closer but Englishmen will withdraw further and further. When they finish the conversation, they are far from the place they stood. Kinesics is also called (6) body language, that studies the meanings of the movement of (7) all parts of body and it includes many nonverbal behavior such like (8) eye language, gestures, postures, facial expressions, touch and so on. Paralanguage refers to all kinds of sound signs made by (9) mouth, which can express certain emotions and ideas. Paralanguage is not the phrases and sentences with clear meanings. It is to transform information by sound, such as "Ouch". Except this, the pitch of tone (10) and loudness or quietness of voice also belongs to paralanguage. And some researchers believe that clothing belongs to paralanguage, too.
