Im gonna make a thread of cog function eye movements and other micro expressions! Feel free to add anything
Si- (Kims eyes in this) smooth, low down, tend to move along a horizontal plain
Se- focused on tangible things in view, often higher up but basically anywhere is fair game, and go from one place to another rather than smoothly sliding. Can move their head/body but keep their eyes focused on one thing easily
Ni- flutter along a horizontal plain in the slightly lower middle part of the eye, following an internal thought process rather than looking at tangibles. (I’m sorry but this gif is my absolute favorite example)
Ne- up and to the side/corner of the eye. Also not focused on tangibles, but smooth like Si.
Fe eyebrows - highly (pun intended) expressive! Often go up when the person smiles, usually furrow and unfurrow on command, really show all emotions to some extent.
Fi eyebrows - usually stay fairly stable when other facial expressions change.
Fe smile - corners go up and the smile reaches wide, while the middle of the top lip is not forced up but instead is slightly held back/down. More tension in the cheeks/outside of the mouth
Fi smile - Middle of top lip goes up almost into a type of snarl (for lack of a better word), corners of the smile may go up or down but the general direction of the smile is up rather than wide, more tension in the top lip/nose area
Ti body language - I could talk about their low disengaged eyes or calm facial expressions, but my favorite physical manifestation of Ti is the light pinch when conveying the preciseness of their words.
