Emotions and gestures liar may contradict each other. For example, a person says that he is confident in his words, but his face at the same time may be surprised and scattered. Or your partner says that he agrees with you, shaking his head at the same time in a negative gesture. Also, if violently gesticulating man stopped for a moment, waving his arms, he probably thought about what he should lie on.
Responding to a question, a liar willing to use your own words: - That you broke my favorite dish? - It is not I broke your favorite cup! Or, on the contrary, his answer will be very short: - No!
There is a myth that a person who tells lies, avoids eye contact companion. In fact, so do only small children. An adult who knows how to control himself and to control their emotions, will look into the eyes of your opponent in order to understand, believe it or not that.
Liar will give an unnatural tone of voice. He can answer too loud, unsuitable environment, or on the contrary, speak in a low monotone voice, to lull the attention of the interlocutor. Liar will raise or lower the tone of voice in those places where it would be illogical.
