Body language is a form of non-verbal communication involving the use of stylized gestures, postures, and physiologic signs which act as cues to other people. Humans unconsciously send and receive non-verbal signals through body language all the time.
One study at UCLA found that up to 93 percent of communication effectiveness is determined by nonverbal cues. Another study indicated that the impact of a performance was determined 7 percent by the words used, 38 percent by voice quality, and 55 percent by non-verbal communication. Your body language must match the words used. If a conflict arises between your words and your body language, your body language governs. The components of body language include:
Eye contact: The impact of your message is affected by the amount of eye contact you maintain with the person with whom you are speaking. One who makes eye contact is normally perceived as more favorable and confident.
Posture: Find comfortable sitting and standing postures that work for you; avoid any rigid or slouching positions.
Excessive or unrelated head, facial, hand and body Movement: Too much movement can divert attention from the verbal message. Your facial expressions should match the type of statement you are making; smile when saying “I like you”, and frowning when saying “I am annoyed with you”. Occasional gestures that reinforce your verbal message are acceptable.
