Utilize Hand Gestures to Communicate Non-Verbally.

Instructions

Pay attention to the hand gestures of the person you are talking to.
Notice the speed and position of the gesture to understand the attitude of the person.
Use hand gestures to communicate without speaking.
Rubbing the palms together is a way to show positive expectation. Thumb and finger rub is used to express money expectancy. Steepling hands is used to show confidence.
Be aware of the situation.
Hand gestures can be misinterpreted if the context is not taken into account.
Be aware of the mouth guard gesture.
This gesture consists of the hand covering the mouth and the thumb pressed against the cheek. It indicates that the person is lying.
Look out for the nose touch gesture.
This gesture is a more subtle version of the mouth guard gesture. It may consist of several light rubs below the nose or it may be one quick, almost imperceptible touch.
Notice the eye rub gesture.
This gesture is the brain’s attempt to block out the deceit, doubt or lie that it sees or to avoid having to look at the face of the person to whom he is telling the lie.
Be aware of the ear rub gesture.
This gesture is an attempt by the listener to ‘hear no evil’ in trying to block the words by putting the hand around or over the ear.
