Autistic Behaviour as Communication


Behaviour can be a sign of unmet need, overload, pain, uncertainty or difficulty communicating.


What looks like refusal, aggression, avoidance, repetition or “challenging behaviour” may be the visible part of a much bigger sensory, emotional or nervous-system experience.


Explore clear visual resources about behaviour as communication in autism, including sensory needs, regulation, distress, nervous-system responses and what may be happening beneath the surface.

Cover of a book about understanding behavior in non-speaking autism. Features a young boy with headphones, surrounded by speech and thought bubbles with icons representing various emotions and actions, flowers, and decorative leaves.
