There Are 19 Types Of Smile But Only 6 Are For Happiness.

Which is a real smile in the two portraits above?

The “science of smiling” was initiated by Charles Darwin. He noticed that the cause, consequences and manifestations of smiling is universal, whereas many other nonverbal of body language behaviours (like gestures or touch) differ between cultures and are, therefore, probably learnt. Babies born blind smile like sighted infants. We begin smiling at five weeks: babies learn that crying gets attention of adults, but smiling keeps it. Darwin also observed that smiling and laughter often occurred together, and therefore, had similar origins. Happiness, he thought, was similar to amusement. We are “prewired” to connect with others via this system. However there maybe cultural differences in rules of smiling. For instance, it has been demonstrated that in America, people smile more in the south than the north. Many east Asians cover their mouth when smiling.

Our sensory system first collects the information prior to a smile, and this emotional data is communicated to the brain, exciting the left anterior temporal region in particular, which then activates the surface of the face, where the zygomatic major, which resides in the cheek, tugs the lips upward, and the orbicularis oculi, which encircles the eye socket, squeezes the outside corners into the shape of a crow’s foot. The entire event typically lasting from two-thirds of a second to four seconds — and those who witness it often respond by mirroring the action, and smiling back. Other muscles can simulate a smile, but only the peculiar tango of the zygomatic major and the orbicularis oculi produces a genuine expression of positive emotion. Psychologists call this the “Duchenne smile,” after the French anatomist Guillaume Duchenne, and most consider it the sole indicator of true enjoyment.
