The Science behind
The Groundwork
The Groundwork is based on a simple understanding:
Children’s behaviour, emotions and attention are closely connected to the state of their nervous system.
When the system feels safe and settled, children are able to focus, learn, connect and cope with challenges.
When it’s overloaded, the brain shifts into protection mode - and everything becomes harder.
This approach draws on research from neuroscience, child development and stress physiology, while focusing on practical changes that support children in real life.
What is the Nervous System?
The nervous system is the body’s regulation and safety system.
It is constantly scanning the environment and asking one question:
Am I safe enough to learn, connect and engage?
When the system feels calm and safe, we are able to:
-
concentrate and think clearly
-
manage emotions
-
solve problems
-
communicate and interact positively with others
When the system feels overwhelmed or under pressure, it shifts into protection mode.
This can show up as:
-
big emotional reactions
-
anxiety or worry
-
shutdown or withdrawal
-
restlessness or agitation
-
irritability or resistance
-
difficulty focusing or making decisions
This isn’t a choice.
It’s the body responding to stress.
For some people, especially after ongoing stress, change or trauma, the nervous system can learn to stay on high alert.
Always scanning.
Always braced.
Ready for danger - even when they are safe.
Over time, survival mode can begin to feel normal.
Children often show this more quickly because their systems are still developing - but the same regulation system operates across the lifespan.
How Stress Affects the Brain and Body
When the nervous system detects stress or threat, it shifts into protection mode.
This activates the body’s stress response - often known as fight, flight or freeze.
In this state:
-
the thinking brain becomes less accessible
-
attention and memory reduce
-
emotional reactions increase
-
the body prepares for survival rather than learning or problem-solving
This response is automatic and protective.
When the nervous system is under prolonged or repeated stress, it becomes harder to return to a calm, regulated state.
Regulation Happens Through Safety
The nervous system does not regulate through reasoning alone.
It responds to signals of safety.
These signals come from:
-
calm, regulated adults
-
predictable environments and routines
-
connection and supportive relationships
-
reduced sensory and emotional overload
This process is known as co-regulation.
Children learn to regulate themselves over time by experiencing safety and regulation in their environment.
Environment Shapes Regulation
Research in neuroscience and child development shows that regulation is strongly influenced by the conditions around a child.
When environments are:
-
calm
-
predictable
-
supportive
-
appropriately paced
-
the nervous system is more able to settle.
When environments are highly stimulating, unpredictable or pressured, the stress response is activated more frequently.
This is why supporting regulation is not only about teaching strategies.
It’s about creating environments that allow the nervous system to feel safe enough to learn, engage and connect.
The Groundwork applies this science in practical ways - supporting the environments, routines and relationships that help children’s nervous systems function at their best.
