The ticks of repetitive gestures is a recursive operation within in episodic memory, most likely (within the context of most here) dealing with the sense of self in relation to sense of others. A breakout from the memory algorithm is what they are fixated upon (likely traumatic and seemingly unmoveable). It can result in nervous ticks and facial spasms while the attempt is underway, depending on which cranial nerves are being tripped up in whatever simulations are underway.
A introduction to recursive operations.

I posted yesterday a video of Sartre's play "No Exit" where the phenomena is played out across three people with personal faults equally balanced that leads to mutual self torment and sadistic attacks on one another. It's pretty close to what a depression looks like internally from those suffering from a socially induced depression, the concept that "Hell Is Other People":

Sartre's play toys with the psychology of recursive thinking in a interpersonal triad the whole time, and you can very well imagine why the bizarre perplexing art is how it is (to endlessly make you ponder why) and the paper knife is there for when it all boils up to stabbings in rage.
The interpersonal triad of that llay isn't unlike the conscious-unconscious networks of the individual human mind playing off itself continiously.
This whole process, once understood and can be successfully navigated, can result in a recursive ennui where every person teying to look cool and act unique comes off as looking like other people you already met, and you already can predict the range of statements, conclusions and emotions they will state (all very original from their perspective). At this point the only gestures you'll give up involuntarily is frowning and pounding your head on the desk/table/wall. I've just met you, yet I've known you forever, please go away you uninteresting person. The trauma of a deep recursive depression can be easily resolved by that point, but a depression felm fruitless familiarity takes over. You won't suffer from PTSD like others anymore, but you'll suffer interpersonally from already being able to guess where every conversation is going to go with them from that point on, and not even caring if they are trying to hurt you, or care to impress them, as it doesn't matter anymore, cause you already done it, a hundred times.
