Have you ever looked at someone smiling and thought to yourself that he/she was not really smiling? Well then, you have the makings of a humor detective!! That's right, people can and do smile for no reason. As a matter of fact a French neurologist, Dr Duchenne conducted several hours of research on the difference between a fake smile and a genuine smile by observing patients who had severe brain trauma or strokes. His findings revealed that two parts of the brain control smiling. Voluntary smiles are controlled by the motor cortex. The types of smiling that is intentional and brings good feelings to your body (receiving gifts, getting an A in a course, etc). Smiles that are spontaneous and the result of some emotion (daughter's wedding, surprise birthday party, etc) are controlled by the cingulate cortex. Patients who had a stroke or a brain injury can appreciate a joke and smile if the cingulate cortex wasn't damaged. Dr Guillaneume Duchenne further defined the differences in smiles. A true genuine smile stimulates the zygomatic major muscle and lifts the corners of the mouth in an upward movement and the muscles around the eyes (the orbicularis oculi) to wrinkle up, also known as crow's feet, by pulling on the cheeks. Dr Duchenne noticed that "fake" smiles or smiles not attached to any specific emotion, engages the zygomatic muscle but not the orbicular oculi muscle. This is why true, voluntary and intentional smiles are referred to as Duchenne Smiles.

WOOP WOOP!!! 19 out of 20! YAY! Very interesting, this whole smiling ordeal. :D
ReplyDeleteTry having to test 40 people with this test? It's soooo hard! It's my science fair project!
ReplyDeleteI took the test and got 19 out of 20. I felt confident that I would score well because I've always been able to tell when people are being genuine and when they're being fake. Great way to test your knowledge of genuine and fake smiles!
ReplyDeleteI took the test I got 13 out 20 correct, I found it to be weird, trying to pick real and fake smiles. sometimes you just don't know
ReplyDeleteEither I did something wrong, or the test is no longer accessible in its entirety as of today (10/19/15).
ReplyDeleteOn entering my response to the first smile, and hitting the "next" button, instead of seeing the second smile, I got a 404 (page not found) error message.
I am not smiling now.
