Real smiles vs. fake smiles

I am giving a deception detection workshop tonight. One of the techniques I will discuss is how to tell a real smile from a fake smile. Different parts of the brain are responsible for real and fake smiles. The unconscious part of the brain is responsible for a real smile, while the conscious part of the brain creates a fake smile.As well as making the mouth muscles move, the muscles that raise the cheeks in a smile also contract, making the eyes crease up. There are few key features which distinguish a real smile from a fake one. In a genuine smile the fold in the fleshy part of the eye between the eyebrow and eyelid moves downwards and the corners of the eyebrows dip slightly. Real smiles are all about the eyes. I did research on smiling as the national spokes person for The Natural Dentist. I will be blogging about this more tomorrow in the meantime here’s a great link from the BBC which provides a test to determine if you can determine a genuine smile from a fake one through recognizing micro expressions: http://www.bbc.co.uk/science/humanbody/mind/surveys/smiles
