Decoding Body Language

According to Ernest R. Hilgard, “Body language or Kinesics is a term developed by behaviorists to refer to the way various human gestures reflect feelings and attitudes. The simplest manifestation of this is how we shake our heads from side to side to signify that we disagree; or its opposite, nodding to show that we agree with what is being said. Rubbing the back of one's ear connotes lying; while rubbing one's nose usually indicates confusion. But what if the person making the gesture actually feels the exact opposite inside?

Body language or Kinesics is a phrase that was made by behaviorists to refer to the way some human gestures can affect emotions. The simplest manifestation of this is how we shake our heads from side to side to signify that we disagree; or its opposite, nodding to show that we agree with what is being said. Rubbing the back of your ear shows you are lying; while, rubbing your nose is apparently a sign of confusion. But what if the person making the gesture might feel the exact opposite in their mind?
