Body language is a form of non-verbal communication, which consists of body posture, gestures, facial expressions, and eye movements. Humans send and interpret such signals almost entirely subconsciously.
Body language is the unspoken or non-verbal mode of communication that we use in every single aspect of our interaction with another person. It is like a mirror that tells us what the other person thinks and feels in response to our words or actions. 55% of the messages that we convey to other people are transmitted through body language. The actual verbal communication accounts for the other 38% in tone of voice and only 7% in the words we use (*When verbal context is ambiguous).
Body language may provide clues as to the attitude or state of mind of a person. For example, it may indicate aggression, attentiveness, boredom, relaxed state, pleasure, amusement, and intoxication, among many other cues.

Truthful statements are more likely to contain descriptions of emotions that deceptive statements, as well as where in the story emotions are introduced. It's thought that deceivers will mention emotions just before the climax of the story, whereas truth tellers are more likely to mention emotions throughout the story, but particularly after the climax of the story.
