Rhythmic, repetitive behaviors are a hallmark of autism. Hand-flapping, spinning in circles, body rocking, vocalizations such as grunting and muttering, and other habits can be disquieting to people unfamiliar with them. Scientists and clinicians have long puzzled over what these behaviors mean — and how to respond to them.For many years, experts thought repetitive movements resulted from deprivation or even trauma, and that they hindered learning. Psychologist Ole Ivar Lovaas, an early autism specialist, reportedly referred to them as “garbage behavior.”1 He made suppressing these habits a priority. Lovaas and his followers electrically shocked, screamed at, shook and slapped autistic children2. Others prescribed antipsychotics and other stupefying drugs. Even in today’s sometimes gentler treatment paradigms, therapists often train children to have ‘quiet hands’ as opposed to freely flapping ones3.But growing evidence suggests that repetitive behaviors have been misunderstood — and that they may in fact be incredibly useful.

It is often a result for one of the following reasons
Overstimulation: When there are too many sensory inputs, focusing attention away from overwhelming feelings
Understimulation: When there is not enough sensory input or feeling, stimming can allow stimulation of the senses and creating pleasure
Reduction of pain: Engaging in a different activity causes the body to relax.
Self regulation: Overcome anxiety, express distress etc
