What were the first emotions expressed by President Trump after he was introduced yesterday?
Many people in his shoes would exhibit a sincere smile, a social smile or a perhaps a nervous smile. But joy and happiness (or even an attempt at these) were not the expressions (nor the emotions) which Donald Trump displayed (nor felt) when he was introduced by Senator Roy Blunt (R-MO) - just after he was sworn-in and immediately prior to his inaugural address. The first emotions President Trump felt and displayed upon being introduced were that of regret and anger (captured below from 0:24).
In the real world, emotions do not always appear in their textbook, pure and isolated forms. Often two or more emotions are experienced simultaneously. Although, because the motion-capture nature of this telephoto video image (immediately above) is of a bit lower resolution, several key features on Mr. Trump's face in this moment delineate the emotions of both regret and anger. This combination can be also thought of as "bitter-anger" or "bitterness".
Note the lateral, backward and down retraction of the corners of Trump's mouth - this cluster is highly characteristic of regret. The thinning of his upper lip along with the jutting forward of his jaw are highly indicative of anger. Moreover, the muscular tension/contraction of the area above his upper lip and below his nose (termed the "mustache area" regardless of the level of facial hair) - along with the flaring of his nostrils - also projects anger. A third anger indicator is the particular type of tension of his lower eyelids and the partial closure of his upper and lower eyelids. Remove for a moment any political bias you may have - if you have no formal nonverbal training at all, but otherwise have good interpersonal and social skills - these emotions should jump out at you.
