Before you go and start mimicking someone's every word, be aware that mirroring must be subtle as to appear to be unconscious!
This is the difference between a good conversation and a punch or slap.
According to some scientists, there is a neuron that affects part of the brain that is responsible for recognition of faces and facial expressions.This neuron causes the ‘mirroring’ reaction when you see smiling or frowning faces.It is a powerful tool that we use instinctively without even being aware of it.The most obvious forms of mirroring are yawning and smiling.Mirroring can be achieved by copying any of these things: Some say that accents can be mirrored, but I don't think this is true.
Mirroring body language is a way to bond and to build understanding.
Mirrors are used in microscopes, telescopes, and lasers, as well as in devices that collect light for solar power and the devices that make holograms.
For instance, a common type of telescope called a reflecting telescope has a concave mirror (curved inward) at one end.
In other words, it causes you to copy facial expression that you see on others.
Mirroring body language is a non-verbal way to say ‘I am like you, I feel the same’.
Psychologists often examine mirroring and when doing so they are most often like to look at body language.
