Self-stimulating Behaviors – Stimming

Self-stimulating behaviors or “stimming” are stereotyped or repetitive movements or posturing of the body. They include mannerisms of the hands (such as flapping, finger twisting or flicking, rubbing, or wringing hands), body (such as rocking, swaying, or pacing), and odd posturing (such as posturing of the fingers, hands, or arms). Sometimes they involve objects such as tossing string in the air or twisting pieces of lint. These mannerisms may appear not to have any meaning or function, although they may have significance for the person, such as providing sensory stimulation, communication, or soothing when wary or anxious. These repetitive mannerisms are common in children with ASD.
