奇怪的肢體語言
Liars often fidget, turn away from the person to whom they are speaking, blink rapidly, smile less and have pitch changes in their tone of voice. They may cross their arms which is a sign of being “closed” or trying not to reveal too much information. Sometimes people fidget excessively when they are lying. They could fidget with a part of their body or touch parts of their face, an ear or a nose or play with keys or another item that they have in their hand.
