Mimicry

We now know through the work of neuroscientists that the human brain is wired to mimic other people, and this mimicry involves actual involuntary, physiological experience in the observer. Human beings tend to imitate actions that they see. Physiologically, our brains include mirror neurons, which react to actions that are seen as if we are doing the action ourselves. It is largely an unconscious and automatic experience. When we hear people speak, observe their vocal nuances, watch their posture, gestures, and facial expressions, etc., neural networks in our brains are stimulated by the "shared representations," generating feelings within us that reflect the experience of those we are observing.
