On the BBC Real Smile Versus Fake Smile Quiz I got 19/20 correct. Fake smiles are created from conscious signals of the brain. Genuine smiles are created from the unconscious brain. Different facial muscles are used to create a genuine and a fake smile. It is sometimes hard to tell the difference between a fake smile and genuine smile. One way to tell that a smile is genuine is by looking to see if his or her eyelid moves. The code that researchers use to determine if a smile is fake or genuine is the Facial Action Coding System, which was created by Dr. Paul Ekman. Now that you know what to look out for try taking the quiz at http://www.bbc.co.uk/science/humanbody/mind/surveys/smiles/index.shtml
and see how you do!
