2.1 The Definition of Body Language
Considering the endless stream of body language theory, it has been evolved and defined by many experts. Samovar and Porter’s defined that body language was the technically, biologically, psychologically or culturally framed exchange of significant messages which are not conveyed by verbally speaking out but passed by the body, gesture, symbol or relevant context and surroundings and so on. (Samovar, L. & Porter, R, 1995: 14) The definition in Oxford Advanced Learner’s English-Chinese Dictionary is that the process of communicating what you are feeling or thinking by way of you placing or moving your body instead of by words. (Oxford Advanced Learner’s English-Chinese Dictionary, 1997: 175) Zhao Tao shows another famous definition of body language. He indicates that body language is a term of communication for using body movements or gestures rather than, or in addition to, sounds, verbal language or other communications. It can form a part of category of para-language, which describes all kinds of human communications that are not verbal language. That is to say, it includes the slightest of movements that many people can not be aware of, including winking and subtle movement of the eyebrows. Moreover, body language can also containing the use of facial expression (Zhao Tao, 2000). Body language is an essential medium that can help people communicate with each other. It is Richard Nordquist, a grammar and composition expert, defines that nonverbal communications depend on body movements to transfer messages, just like gestures, posture, and facial expressions. Generally speaking, body language can be adopted consciously or unconsciously. It may go with a verbal message or act as a substitute for speech (Richard Nordquist, 2015). No matter how specific or abstract the definitions are, the value of body language is integral and the use and functions are inevitable.
