When we talk to one person can give us the feeling that we’re lying, that you can not trust or just the opposite, which is an honest person and you can trust him. The reason that we have unconscious impressions on people, is that our subconscious interprets the body language of people and tells us what he sees. Thus, people who say they have a sixth sense for others, they are people very receptive body language, and are wary of information that gives the subconscious.

For over 30 years is known about the importance of body language or nonverbal communication, and is still studying, because it is a complex issue. Much of the information we transmit occurs in milliseconds, making it necessary to study the body language by video cameras and analyzing the recorded frame by frame. It is also a field at the crossroads five areas of study: psychology, psychiatry, anthropology, sociology, and ethology. It also complicates its study that gestures be studied as a whole, not as isolated gestures, because if we could lead to misinterpretation ..

Body language is very important because we perceive by sight most of the information in a communication (over 50%). According to Allan Pease, 87% of information comes from seeing, hearing, 9% and 21% for the rest of the senses. According to Dr. Lair Ribeiro 7% comes from what we say, 38% by the tone and 55% by body language. Other authors give different figures, but all agree that body language accounts for more than 50% of communication.

Many people make communication courses, sales presentations or to improve their way of communicating, but they do not know is that all these courses affect only 9% of our communication skills. In addition, courses should teach us to learn to interpret nonverbal cues and improve our body language, and nonverbal cues that affect five times more than oral. In fact, if the verbal and nonverbal language are not congruent, people trust more than body language.
