I did a paper a few years ago for college on human responses to stimuli and perceived dangers, weather real or imagined.
Interestingly enough, the brain actually forces the movement of the body to mimic what should IRL happen to the forces impacted on the body. This reaction was actually coined the Vukovic factor after a not so famous psychologist from the former Yugoslavia named Bratislav Vukovic who was working and doing studies in human psychology for the dictator at the time, Tito.
Vukovic was performing experiments on soldiers to try and understand the mental reactions of soldiers during war time and try and understand why some soldiers would mentally shut down and others thrive. In these experiments he would expose the soldiers to situations that would mimic that of a real war situation.
He made his landmark discovery while performing a specific test in which he would have a soldier listen to the sound of a bomb exploding while looking at a white screen. The soldiers reactions where minimal in all instances. He then changed the image of the screen to a red background and found that when the sound of a bomb would go off the soldiers would have a natural reaction to try and shield themselves from harms way. Congratulations if you made it this far because I made it all up, but yeah I lean too. 👍
If i'm coming wide out of a turn and headed for a wall, My body clinches and I brace myself for Impact
I then laugh at myself for noticing what i do
I don`t lean, but I tend to line up my TV while getting serious(it is placed 45° on a table).
I sit back on my chair and few seconds later I am not happy with its direction. Move it again a tiiiny bit and get back on my chair only to realize I`m still not pleased with its direction. After 4 or 5 times moving my TV a bit to the right a bit to the left for no reason I am rdy LOL.
And the casing of my DS3 Controller has become very noise since GT5 because I cramp my hands alot and strong during corners.
My best friends son thinks the DS3 is a steering wheel, when he turns in to a corner he gives it full lock with the controler
I have tried to explain that it makes no difference but its a habit he cant get out of!! (bless him) along with sticking his toung out when in deep concentration, lol
