8 of 10 just do it. If you ask someone to reproduce a certain movement, posture, sport figure, dance or emotion (like ” be Karate Kid, superman or a goalkeeper”) they will probably reproduce it without previously skills, practice or actually being a real dancer or the Karate Kid. How does this work? The mirror neuron theory suggests that human beings use a very special kind of neuron to "copy” behavior or actions, for learning new skills by imitation. The theory has a very important function, specially in children’s development who need to copy behaviours and actions. But, what happens when your mirror neuron copies wrong behaviours, actions or movements? If you, as runner, constantly see other people running (whether they have good or bad technique), your mirror neuron will lead you to imitate their running. Unfortunately, the commonly used acronym WYSIWYG is right.
