Stimming

Repetitive movements, sounds, or behaviors that serve self-regulatory functions, commonly associated with autism but present in all people to varying degrees. Examples include hand-flapping, rocking, spinning, humming, fidgeting, and repeating words or phrases. From a neurodiversity perspective, stimming is understood as a natural and important self-regulation mechanism that helps autistic people manage sensory input, process emotions, express feelings, and maintain equilibrium. Traditional behavioral interventions like ABA have historically sought to suppress stimming, which autistic self-advocates argue is harmful—removing coping mechanisms essential for well-being. The debate around stimming reflects broader tensions between normalization and acceptance in autism support.
