Jan Hargrave is a body language expert in America. I was very pleased to hear Jan Hargrave speak the other day. She explained that although our mouths may lie(撒谎), our bodies do not. For the most part, we all have the ability to tell when people are lying to us by reading their tone of voice and body signals.

It was Professor Albert Mehrabian who discovered that we express our feelings and attitudes（态度）with 55 percent body languages, 38 percent tone of voice and only 7 percent actual words. In other words, if I asked you how you were doing and you said “fine”, that word wouldn’t mean anything by itself. It would be your body signals and how you said it that would let me know how you were really doing.

So, can you tell when people are lying to you? Jan Hargrave says we lie with the right side of your brains, so it is our left hand that tips us off.  A person touching his nose, pulling at his ear or rubbing his eye with his left hand might be lying to you. Also, a person who, in a way crosses fingers might just be lying.

Here are some things we do to shut people out. We continually look at our watch. We fail to make eye contact. We fail to look up from the paper or away from the TV. Our body is leaning away from them.

By paying attention, we can open these important lines of communication and see the truth more clearly. I think it would be a mistake to use these tools to control or lie to people, but we need to realize the signals we are giving, so we can show people that they really do matter to us.
