Threat matters.
Across evolution, animals that could detect danger and respond quickly were simply more likely to survive. Sometimes that meant moving away or becoming still. Sometimes it meant preparing to defend themselves – or actively doing so!
Jaak Panksepp described FEAR as one of the brain’s primary emotional systems – part of an evolutionarily old network involved in detecting and responding to threat. In his model, FEAR helps organise avoidance, escape and defensive behaviour when danger is perceived.
But this is where language can quickly get confusing.
The FEAR system is not the same thing as the conscious feeling we describe as fear.
Joseph LeDoux has argued strongly for this distinction. Brain circuits involved in detecting and responding to threat can change what we notice, what happens in our body and how we behave, without necessarily producing the conscious experience we would describe as “feeling afraid”.
That distinction matters enormously when we are thinking about young people.
A Principle – A Note on Language
Why FEAR is capitalised
Panksepp capitalised the names of his proposed primary emotional systems, including CARE, FEAR, SEEKING, PLAY, RAGE and PANIC/GRIEF, to distinguish the underlying biological systems from the everyday words we use to describe feelings and behaviour.
So FEAR refers to the proposed primary emotional system, while fear refers to the lived experience of being afraid.
A child may therefore move away from a situation, become unusually still, react aggressively, seek reassurance or struggle to engage without being able to tell us, “I am frightened.”
They may not experience the situation in those terms at all.
So asking “What are you scared of?” may sometimes be exactly the right question and, annoyingly, sometimes it may not help very much!
A more useful starting point might be:
“What seems to be happening when this young person experiences something as threatening?”
Why don’t we all respond to threat in the same way?
If threat simply produced one predictable response, understanding defensive behaviour would be relatively easy.
But it doesn’t.
The way any animal (including us!) responds depends on far more than whether something feels threatening. It also depends on how close the threat is, whether escape seems possible, whether the situation can be controlled, what has happened before and what options appear to be available.
The psychologist and neuroscientist Michael Fanselow has described defensive behaviour along a Predatory Imminence Continuum – essentially, the way defensive responses change as a threat becomes psychologically closer and more immediate.
Moving away may be the safest response. Becoming still may help gather information or avoid detection. Active defence may become more likely when escape no longer seems possible.
This is why familiar descriptions such as fight, flight or freeze are useful shorthand (and we certainly use them in Motional), but they are not three neat boxes that people simply drop into.
Defensive behaviour is dynamic.
A young person may move between withdrawal, stillness, agitation, avoidance, reassurance-seeking or active resistance as a situation changes. And again, behaviour observed in a single moment does not tell us what is happening internally.
The same outward response can have very different meanings for different young people.
A Motional Principle
Useful shorthand is not the same as biological fact
Terms such as fight, flight and freeze can be very useful ways of describing patterns of defensive behaviour.
Polyvagal Theory has taken this further, offering an influential model in which different autonomic states are linked to mobilisation, social engagement and immobilisation. The model has been widely used in education, trauma-informed practice and psychotherapy.
But some of its core claims about the anatomy, evolution and organisation of the autonomic nervous system are now strongly contested. A major expert review published in 2026 concluded that several fundamental premises of Polyvagal Theory are not supported by the wider neurophysiological evidence. Porges has subsequently challenged that conclusion, so the debate continues, and we observe with interest.
At Motional, we do not want to choose a convenient model and present it as fact. We are much more interested in where models are useful in helping us communicate complex ideas and support the young people in our care, without overstating what the science can tell us.
So fight, flight and freeze remain useful descriptions, but we should be careful about treating them as three fixed biological states, or assuming that an observed behaviour tells us exactly what is happening in a young person’s nervous system.
The reality is more complex, and that complexity matters.
This all leaves us with another important question:
What makes something feel threatening in the first place?
Not every threat is obvious. A loud noise, an angry face or something moving rapidly towards us may carry fairly immediate information about possible danger.
But much of what young people respond to is far less straightforward. It might be a particular tone of voice or sound, a sensation, being asked to read aloud, walking into a busy classroom – or an empty hall. It might be not knowing what is going to happen next, a look from another pupil (or what is perceived as one), or an adult moving closer.
None of these things is inherently threatening in every situation or to every person. What matters is partly what the young person has learned to expect.
Our brains are constantly using previous experience to make predictions (LINK HERE) about what is likely to happen next. When something resembles a situation that has previously ended badly, the brain and body can begin preparing for danger before we have consciously worked out why.
And that preparation is not simply happening in the brain. Defensive responding involves an ongoing exchange between brain and body. Changes in heart rate, breathing, muscle tension and other bodily systems provide information back to the brain, while the brain continuously interprets those signals alongside what is happening around us.
So what feels threatening emerges from a mixture of what is happening now, what has happened before, what the body is doing and what we predict may happen next.
Two young people can therefore experience the same classroom, the same adult or the same moment or event very differently.
And the same young person may experience it differently on another day.
A Principle
Interoception – how the body becomes part of what we feel
Information does not only travel from the brain to the body – in fact, in some important pathways it is almost the opposite! The brain is constantly receiving information from inside the body, from things such as our heart, breathing, muscles, gut and temperature.
The vagus nerve is a good example. Around 80% of its fibres are afferent, carrying sensory information from the body towards the brain, with the remainder being efferent and carrying information in the other direction.
This wider process of sensing what is happening inside our body is known as interoception.
Those bodily signals are not emotions in themselves. A racing heart does not automatically mean fear, just as a tense stomach does not automatically mean anxiety. The brain has to make sense of those signals alongside what is happening around us, what has happened before and what we expect may happen next.
So the body does not simply respond to our experience – it helps shape it.
At Motional, we think of the brain and body as a system, not as two separate things.
So how do we recognise a pattern we cannot see directly?
We cannot directly observe another person’s FEAR system, just as we cannot directly see their prediction that something is threatening. And we cannot know, from a single behaviour or a single moment in time, exactly what is happening inside a child’s body or brain.
What we can observe are patterns.
A young person may regularly avoid particular situations or struggle to manage change. They may become unusually still when demands increase, repeatedly seek reassurance, become overly concerned about making mistakes, or appear more controlling, agitated or confrontational in certain contexts.
None of these behaviours proves that FEAR is driving the response. But when we observe behaviour over time, alongside what we know about the young person, their relationship and environment, patterns can begin to emerge.
This is why Motional uses practitioner observation over time rather than asking adults to identify a hidden emotional state.
A Snapshot does not ask “Is this child frightened?” It brings together repeated observations from an adult who knows the young person well. How often does this happen – always, often, sometimes, rarely or never? Does it seem to happen in particular situations, or has something changed?
The aim is not to identify FEAR as ‘a cause’. It is to create enough structured Insight to ask better questions about what may be happening beneath the behaviour.
Patterns do not give us certainty. They give us somewhere more useful to look.
What do we do with that Insight?
Recognising a pattern is only useful if it changes what we do next.
If a young person appears to be responding to something as threatening, a useful first response is not to persuade them that it is safe – it is to be curious about what their experience may be telling us.
A Motional Principle
Professional Curiosity
Professional curiosity is really about resisting the temptation to decide too quickly that we know what a behaviour means.
Something may look familiar. We may even have seen very similar behaviour many times before. But that does not necessarily mean that the same thing is happening for this young person.
So rather than jumping immediately to an explanation, we stay curious. What has changed? What tends to happen around the behaviour? What do we know about this young person, their relationship and environment, and what they may have learned to expect?
That does not mean endlessly questioning everything or refusing to make professional judgements. Quite the opposite.
It means holding those judgements lightly enough to notice when the evidence suggests we may need to think again.
We need to stay curious about what seems to make the situation harder, and what appears to help.
That might mean making something in the environment more predictable, helping the relationship feel more consistent, giving the young person clearer information about what is going to happen next, or making sure they have some way to step back, ask for help or regain a sense of control.
The response itself will depend on the young person and the situation. Sometimes reassurance will help. Sometimes it might be clearer information, more preparation, greater choice or simply an adult who notices what is changing before things escalate. At other times, what helps most may be a calm and predictable boundary.
Really importantly, some of these changes can be made structurally – through the way we organise a classroom, a school or our everyday practice. A whole school approach means creating conditions that support everyone, while often making the biggest difference to those who are most vulnerable, without singling them out or creating unnecessary stigma or segregation.
A Motional Principle
A Whole School Approach
A whole school approach is not about giving every young person exactly the same thing.
It is about designing the wider environment, routines, relationships and expectations so that they work better for everyone, while still allowing additional support where it is needed.
Predictability, clear communication, consistent responses, Emotionally Available Adults and opportunities to ask for help are not specialist interventions. They are good foundations for a school community.
When those foundations are built into everyday practice, the young people who are most vulnerable can benefit without always having to be identified, separated or treated differently first.
Individual support still matters.
But often, the most useful intervention is to develop the environment around young people, rather than continually asking them to adapt to the environment.
The aim is not to remove every possible source of discomfort or uncertainty. Young people also need opportunities to learn that difficult situations can be managed and that predictions of threat do not always come true.
But that learning is far more likely when challenge happens within a relationship and environment that feel safe enough for new expectations to develop.
FEAR therefore gives us another reason to look beneath behaviour. Not to decide which defensive state a child is in, or to label a response as fight, flight or freeze, but to ask:
“What might this young person be expecting right now, and what experience might help them expect something different next time?”
Acknowledging the Evidence
Motional Foundations brings together evidence from multiple disciplines to explore how Emotional Wellbeing develops and how that understanding can inform practice.
This Foundation draws particularly on Jaak Panksepp’s work on the FEAR system, alongside Joseph LeDoux’s work on defensive survival circuits, research into threat imminence and defensive behaviour, and the growing evidence base around interoception.
We have also referenced Polyvagal Theory because of its considerable influence in education, trauma-informed practice and psychotherapy. Some of its core neurophysiological and evolutionary claims are now strongly contested, and there remains an active scientific debate around the theory. We therefore draw a deliberate distinction between models that may be useful for communicating complex ideas and claims that can be treated as established biological fact.
As throughout Motional Foundations, none of these theories provides a complete explanation for an individual young person. They offer different ways of becoming more curious about patterns of behaviour, experience, relationship and environment.
