Body language is described simply by psychologists as a language of signals. They say we express our feelings and thoughts in gestures, movements and attitudes, unaware that we are doing so.
If you like, this language is what we say without speaking, which is a great deal. Only part of what we tell those around us is conveyed by the spoken word. Movements, usually controlled by the subconscious, say more. Every day we unconsciously send many signals through the body. Kinesics, the study of body movement, will tell us that 50 percent of information on the character, impact and credibility of a person is conveyed by body language.
