Stereotypy refers to repetitive movements, sounds, or actions — often called “stimming” — that an individual uses to regulate their sensory experience or emotions. Common examples include hand-flapping, rocking, vocal sounds, or lining up objects. Stimming is most often associated with autism, though everyone engages in some form of self-regulating behavior. ABA approaches stimming with respect for the individual and only intervenes when the behavior interferes with learning, safety, or daily functioning, never simply to eliminate harmless self-regulation.
