Like when we try to spit, a small puddle of saliva instantly comes into out mouths before it is spit out.
In: Biology
If you’ve heard of Pavlov and his dogs, by conditioning his dogs every time he rang a bell when food presented to them, he eventually had them salivate on command by ringing the bell and no food present.
We associate producing saliva to other activities with the other thoughts and triggers we have. With spitting, as little kids we see others do it, and we try to do it and over time we build up that conditioning to bring producing saliva out on command to the act we want (eating, spitting, licking our lips, etc).
