The Science Behind Behaviour

The Science Behind Behaviour

You will receive the printable unwatermarked version of this infographic

Behaviour is not random. It is the output of the nervous system, shaped by biology, environment, experience and unmet needs. This infographic walks through exactly how that happens, from sensory input arriving through the senses, to the brain processing and interpreting that information, to behaviour as the final visible output.

It covers what happens when the load becomes too much, moving from mild stress through to survival mode, why the same input can look completely different across different nervous systems, and what the nervous system actually needs to move back towards regulation.

Perfect for parent carers who want a clear, visual explanation of why behaviour happens, and for professionals and educators looking for a science based framework to share with teams and families.

What is included:

Full breakdown of the input, processing and output model of behaviour

The four brain regions involved and what each one does

The stress escalation pathway from mild stress to survival mode

Why behaviour looks different from person to person

What the nervous system needs to feel safe and regulated

A high resolution digital download, ideal for printing, sharing with schools and professionals, or keeping as a quick reference when behaviour needs understanding rather than managing.

See the science. Support the system. Change the outcome.
