Many autistic people engage in self-stimulating behaviour, also known as stimming. It may include repetitive use of an object (e.g., flicking a rubber band), repetitive activities involving the senses (e.g., feeling a certain texture), or behaviour involving body movements (e.g., jumping, rocking, spinning, head-banging). Although it varies for everyone, autistic people may stim for enjoyment, to reduce or gain sensory input, or to deal with stress or uncertainty.
