Before we move ahead and study the other gestures of lying, why not take a test- to tell a deliberate lie to someone face-to-face and at the same time be conscious about the gestures which you'll make. This is the best way to experience the lying gesture for your self ( of-course i don't wont you to tell a malicious lie!!!)
I am listing few of the observation which you can do when you are deliberately lying, flushed cheeks, eye-blink rate increases, increase in number of gulps of saliva, fake smile.
