Yes, stimming can sometimes be a form of communication. Stimming and communication in autism are more connected than many people realise, particularly for those who are non-verbal or struggle with spoken language. In these cases, repetitive actions like rocking, flapping, or vocalising may express feelings, needs, or reactions.

Rather than being random or meaningless, stimming and communication in autism often serve as expressive tools. Understanding this can help parents, teachers, and carers better interpret what an autistic person may be trying to convey.

How Stimming Sends a Message

For many autistic individuals, body language carries more weight than words. Here’s how stimming can work as communication:

Expressing emotion

Some forms of expressive stimming clearly reflect emotional states. For instance, hand-flapping might show excitement, while rocking intensely could indicate stress or frustration. Recognising these patterns helps others respond with empathy and support.

A form of non-verbal interaction

Non-verbal communication in autism can include not just facial expressions or gestures but also stimming. These behaviours often signal internal experiences that aren’t easy to put into words, especially in unfamiliar or emotionally charged situations.

Signalling discomfort or need

Signalling in autism might involve increased or altered stimming. A sudden shift in behaviour can point to sensory overload, pain, or a desire to leave a space. Observing these changes can provide important clues.

Understanding stimming and communication in autism allows for more meaningful connection and more effective support strategies.
