Stimming in Public: Why Autistic People Move, Rock, and Make Repetitive Motions

Stimming is self-stimulatory behavior — repetitive movements, sounds, or actions that autistic people use to regulate their sensory and emotional states. Flapping hands, rocking, making repetitive sounds, spinning, fidgeting, clicking — these are stims. They are not random tics or signs of distress. They are regulation tools.

The neurotypical default is to try to suppress autistic stimming. Children are told to stop fidgeting, sit still, stop flapping, be quiet. In school and professional settings, stimming is often corrected or suppressed because it is seen as disruptive or unprofessional. The assumption is that stopping the behavior is a good thing.

For autistic people, suppressing stimming requires cognitive resources that could be used elsewhere. Trying to sit still and not stim while also processing language and social information makes everything harder. Allowing someone to stim while they listen often improves their ability to focus. An autistic person who is rocking while you talk is not dismissing you — they are self-regulating so they can listen better.

Stimming serves multiple functions. It can be calming when anxiety is high. It can be organizing when sensory input is confusing. It can be joyful expression when experiencing something positive. Different stims serve different functions.

Autistic stimming is not the same as ADHD fidgeting, though the behaviors can overlap. An ADHD person fidgets partly because they cannot focus without movement. An autistic person stims partly because it regulates their sensory experience. Both are legitimate regulation tools.

Respect for autistic people includes allowing them to stim without judgment. If an autistic coworker rocks while you talk, they are not being disrespectful. If an autistic person flaps their hands in a situation of joy or excitement, that is not malfunctioning — that is expression.

Many autistic adults have been trained to suppress stimming so thoroughly that they have difficulty identifying when they need to stim and giving themselves permission to do so. Letting autistic people stim is letting them regulate themselves in a way that works for them.
