My Autism Tics: Do YOU Do This? Here are my personal autism tics I have never spoken about before, do you do these to? Autism tics occur when I am feeling nourvousy or anxious about a certain topic of conversation or a situation that is about to or is occurring. My autism tics are very much in controllable, I have no control over when or how they happen. Autism tics do differ from autism stims, as stimming is a stimulators behaviour that helps a person on the autism spectrum calm down or concert rain, where as tics are a reflex reaction to a situation.
