The next time you attend a social function or go to a place where people meet and interact, take note of the number of people who have adopted the identical gestures and posture of the person with whom they are talking. This "carbon copying" is a means by which one person tells the other that he is in agreement with his ideas and attitudes. By this method, one is non-verbally saying to the other, "As you can see, I think the same as you, so I will copy your posture and gesture."
This unconscious mimicry is quite interesting to observe. Take for example, the two men standing at the hotel bar. They have mirrored each other's gestures and it is reasonable to assume that they are discussing a topic upon which they have the same thoughts and feelings. If one man uncrosses his arms and legs or stands on the other foot, the other will follow, lf one puts his hand in his pocket, the other will copy and this mimicry will continue for as long as the two men are in agreement.
This copying also occurs among good friends or people at the same status level and it is common to see married couples walk, stand, sit and move in identical ways. People who are strangers, however, studiously avoid holding mutual positions. The significance of carbon copying can be one of the most important non-verbal lessons we can learn, for this is one way that others tell us that they agree with us or like us. It is also a way for us to tell others that we like them, by simply copying their gestures.
If an employer wishes to develop an immediate rapport and create a relaxing atmosphere with an employee, he needs to copy the employee's posture to achieve the end. Similarly, an up-and-coming employee may be seen copying his boss' gestures in an attempt to show agreement. Using the knowledge, it is possible to influence a face-to-face encounter by copying the positive gestures and postures of the other person. This has the effect of putting the other person in a receptive and relaxed frame. of mind and he can "see" that you understand his point of view.
What is an appropriate title for this passage？
A．Appropriate Social Behavior.
B．How to Make Gestures.
C．Carbon Copying: Showing Agreement Through Gestures.
D．How to Avoid Carbon Copying.
