Stereotypy

Stereotypy is a type of behavior that includes repeatedly doing the same thing over and over again, even though it doesn't seem to help the person who is doing it. For example, someone might flap their hands a lot or walk around in circles. Some people with autism do stereotypy as a way to cope with stress or overwhelming emotions. The behavior looks strange to people who don't understand it, but it's not intended to hurt anyone. Stereotypy helps those with autism manage their emotions and reduce stress in their lives.
