Body language is a term for communication using body movements or gestures instead of, or in addition to, sounds, verbal language or other communication. It forms part of the category of paralanguage, which describes all forms of human communication that are not verbal language. This includes the most subtle of movements that many people are not aware of, including winking and slight movement of the eyebrows. In addition body language can also incorporate the use of facial expressions.
Although they are generally not aware of it, many people send and receive non-verbal signals all the time. These signals may indicate what they are truly feeling. The technique of ‘reading’ people is used frequently. For example, the idea of mirroring body language to put people at ease is commonly used in interviews. It sets the person being interviewed at ease. Mirroring the body language of someone else indicates that they are understood.
Body language signals may have a goal other than communication. Both people would keep this in mind. Observers limit the weight they place on non-verbal cues. Signallers clarify their signals to indicate the biological origin of their actions.
* One of the most basic and powerful body-language signals is when a person crosses his or her arms across the chest. This can indicate that a person is putting up an unconscious barrier between themselves and others. It can also indicate that the person’s arms are cold which would be clarified by rubbing the arms or huddling. When the overall situation is amicable, it can mean that a person is thinking deeply about what is being discussed. But in a serious or confrontational situation, it can mean that a person is expressing opposition. This is especially so if the person is leaning away from the speaker. A harsh or blank facial expression often indicates outright hostility. Such a person is not an ally, and may be considering contentious tactics.
* Consistent eye contact can indicate that a person is thinking positively of what the speaker is saying. Individuals with anxiety disorders are often unable to make eye contact without discomfort. It can also mean that the other person doesn’t trust the speaker enough to “take his eyes off” the speaker. Lack of eye contact can indicate negativity. Eye contact is often a secondary and misleading gesture because we are taught from an early age to make eye contact when speaking. If a person is looking at you but is making the arms-across-chest signal, the eye contact could be indicative that something is bothering the person, and that he wants to talk about it. Or if while making direct eye contact a person is fiddling with something, even while directly looking at you, it could indicate the attention is elsewhere.
* Disbelief is often indicated by averted gaze, or by touching the ear or scratching the chin. So is eyestrain, or itchiness. When a person is not being convinced by what someone is saying, the attention invariably wanders, and the eyes will stare away for an extended period.
* Boredom is indicated by the head tilting to one side, or by the eyes looking straight at the speaker but becoming slightly unfocused. A head tilt may also indicate a sore neck, and unfocused eyes may indicate ocular problems in the listener.
*Sexual desire can be indicated through posture or extended eyecontact.
* Body Language can also be an indirected conversation Body     Language
It should be noted that some people (e.g., people with certain disabilities, or those on the autistic spectrum) use and understand body language differently, or not at all. Interpreting their gestures and facial expressions (or lack thereof) in the context of normal body language usually leads to misunderstandings and misinterpretations (especially if body language is given priority over spoken language). It should also be stated that people from different cultures can interpret body language in different ways.
