Smiling, Real, Fake and Chimpanzees.

'That’s the gist of a study from Bangor University in Wales, which says spontaneous smiles can be spotted by a contraction of the orbicularis oculi — the muscle surrounding the eyeball.'

I've ripped the section about Chimpanzees here, it comments quite interestingly about how they have are two types of smiles, one to show they are aggressive, and one to show themselves as being submissive to one another. I wonder how many fake smiles in human are submissive behaviour? This could explain why the character Brandt uses a slight one as a gestural indication in Equilibrium. He needs to be submissive to the lies told by the character John Preston. It works, but the smile has to be seen as a gesture than an emotion which is why it works.

'Smiling and laughing are universally considered to be signals that show a person is happy. We cry at birth, begin smiling at five weeks and laughing starts between the fourth and fifth months. Babies quickly learn that crying gets our attention - and that smiling keeps us there. Recent research with our closest primate cousins, the chimpanzees, has shown that smiling serves an even deeper, more primitive purpose.

To show they're aggressive, apes bare their lower fangs, warning that they can bite. Humans do exactly the same thing when they become aggressive by dropping or thrusting forward the lower lip because its main function is as a sheath to conceal the lower teeth. Chimpanzees have two types of smiles: one is an appeasement face, where one chimp shows submission to a dominant other. In this chimp smile - known as a 'fear face' - the lower jaw opens to expose the teeth and the corners of the mouth are pulled back and down, and this resembles the human smile.'

I got 10 out of 10. I can't help but think about at the point where the video stops, how much does it influences the decisions. Depending where it cut alters how much we see of how sharply people pulled back to a neutral state. I guess this is a sign of how much the reading of the emotion is dependent on other sensory information, such as setting, story, context and body language.

Above is the demo for the micro-expression training of Paul Ekmans. On this one i got 40% on the first time of trying to be correct, where i was wrong, i did get the correct answer on the following try (without replaying), wonder how good i could get if i actually practiced.
