Body language

Body language is a form of non-verbal communication. Body language is about using behaviour to communicate. Both people and animals use this form of communication. Part of this behaviour is done subconsciously. It is therefore different from communicating using sign language, for example.
The forms of behaviour used in body language include body posture, gestures, facial expressions, and eye movements.
Body language may provide clues as to the attitude or state of mind of a person. For example, it may indicate aggression, attentiveness, boredom, a relaxed state, pleasure, amusement, and intoxication.
Body language is the science of nonverbal signals such as gestures, facial expressions, and eye gaze that communicate a person's emotions and intentions.

Vocabulary of body language
Body language is not spoken, so you have to be careful how you interpret it. A certain movement or facial expression may be quite meaningful, or it may mean nothing at all. As a starting point, the following sections give with some common body language terms and their generally-accepted meanings.
Positive body language
Positive body language is generally quite reliable as an indicator of a person's feelings. It signals interest in the other person and in the conversation.
Relaxed posture - Comfortably seated, relaxed breathing, no visible stiffness or abrupt movements. These indicate no major barriers to communication.
Arms relaxed - Uncrossed arms and hands open (palms up or otherwise visible to the other person) are signs of openness.
Good eye contact - Looking in the other person's eyes, particularly when they are speaking, indicates interest in that person. Proper eye contact involves looking away occasionally to avoid staring.
Nodding agreement - When nods are used to punctuate key things the other person has said, they signal agreement, interest and understanding. However, continual unconscious bobbing of the head usually indicates that the listener is tuning out.
Taking notes - Shows interest and involvement, particularly if notes are on what the other person is saying.
Smiling/adding humour - This is a very positive sign. It signals a warm personal relationship.
Leaning closer - Reducing the distance between two people, particularly when the other person is speaking. Indicates interest is up and barriers are down.
Gesturing warmly - Talking with hands, particularly with palms open, indicates involvement in the conversation and openness to the other person.
For all of these positive gestures, moderation is the rule. When they are exaggerated, they can become more negative than positive.
Negative body language
Body tense - Stiffness, wrinkled brow, jerky body motion, hands clasped in front or palms down on the table. These can indicate concern with the topic or dealing with the other person. Arms folded in front - Creates a barrier; can express resistance to what is being said.
Hand on face - A hand over one's mouth is a closed gesture. Leaning on one's elbow with the chin in the hand can communicate boredom.
Fidgeting - Moving around a lot, playing with things and drumming fingers are usually a sign of boredom, nervousness or impatience.
Arms behind head, leaning back - In a well-established relationship this can be a relaxed gesture. In a new relationship, it is often used to express a desire for control or power.
Yawning - Boredom, confusion. The other person is talking too much or in too much technical detail.
Impatience - Trying to interrupt what the other person is saying, opening one's mouth frequently as if to speak.
Distraction - Eyes flicking about, blank stares, flipping through literature without really reading it, looking at others in the office, looking at the person's body or clothing.
Leaning away - Avoiding moving closer, even when something is handed to the person, is strongly negative.
Negative facial expressions - These include shaking head, eyes narrowed, scowling, frowning
Personality - It comes under behaviour when a person shows his body language and the person in front gets understood what type of person is
For example, A bad boys behaviour is bad anyone can catch after seeing his behaviour
