Every day we see other people respond, fall silent, move closer, or pull away. Almost without noticing, we give them an explanation.
This section invites you to pause for a moment before doing so: to look more closely at what is happening, to notice what we do not yet know, and to ask better questions.
We do not promise to know what is happening inside another person. We offer a more careful way of looking.
There is not one path here for families and another for professionals. We all begin in the same place: an everyday situation.
Let's begin with one.
Constructed scene, written to illustrate the framework.
Monday morning. The teacher asks a child what he did over the weekend. He says he went to the river with his grandfather and that the water was cold.
In the afternoon, the same teacher asks him, "And what else did you do on Sunday?" He did not answer in words. Nor did the teacher identify any other response directed at that question.
Before going on, pause for a moment. What do you think happened?
What we know. One answer in the morning. No answer to the question in the afternoon. That is what we know about these two moments. We do not yet know what explains the difference.
What we don't know. It was the same teacher, but that does not mean everything else was the same. Perhaps he didn't hear the question, or understood it differently. Perhaps he felt he had already said what he wanted to say. Perhaps Sunday had been different and he preferred not to talk about it, or he simply didn't feel like talking, which is also a legitimate way to be. Perhaps something was happening around him at that moment, or between the two of them, that we could not see. None of these possibilities is more likely just because we can name it.
What the body can add. The body is also part of what we can ask about. How had he slept? Was he tired? Had he eaten? Was something hurting or bothering him? These questions do not tell us why he responded one way in the morning and another in the afternoon. They help us recognize information we do not yet have.
One possible reading. With what we know about Monday, we can put forward something more specific: he may have felt he had already said what he wanted to say about the weekend. It is a possibility, not a conclusion; the fact that he did not answer does not, by itself, confirm it.
What would support this interpretation? His own account that he had already said what he wanted to, if he wished to give one, in whatever way he preferred. It could also help to know how the conversation had gone before that second question.
What would lead us to revise it? If he communicated that he did want to continue telling us about it, or if we learned of some circumstance in that conversation that offered another explanation for his not answering.
We do not need to repeat questions or provoke responses to test our ideas. We can keep observing, listen to the person, and look for information that is already available.
Tuesday. The next day, it happens the other way around. In the morning, faced with a similar question, he does not answer. In the afternoon, he does.
What do we do with that? Tuesday does not allow us to decide which explanation is right. The new information invites us to reconsider whether our first explanations were enough to understand what happened on both days. But it does not show that the reading we put forward about Monday's conversation was wrong. That reading can help us think about that situation without becoming an explanation of what happens at other times.
What research says. Research has documented that the same person's performance on certain tasks, such as working-memory tasks, can vary from one moment and one day to the next. It also studies the factors associated with that variation. But those findings do not allow us to know why this child answered or did not answer in these situations.

Not every difference requires us to find a cause right away. We can listen to whatever the child wants to communicate, respect his not answering, and stay attentive to what he may need.
Go back to your first impression. Which part was observation, and which part was assumption? What would you need to know, and whom would you need to listen to, before calling it understanding?
How we learned to look. We separated what we knew from what we assumed. We opened up possibilities: in communication, in the context, in the body, and in the child's own decision. We put forward one possible interpretation, and considered what information might support it and what would lead us to revise it, without turning it into a general explanation of the person. The new information led us to reconsider whether our first explanations were enough.
A responsible interpretation is not necessarily a correct one. It is one that recognizes its limits, considers alternatives, and remains open.
Looking at what came before — Behavior Is Not the Beginning of the Process — To explore how to widen the window of observation.
Exploring how a response can vary — Access Variability — To examine differences between moments without assuming a loss of capacity.
In the scene, you practiced a way of looking: separating what we know from what we assume, opening up possibilities, and leaving the interpretation open. The readings that follow continue that work with other situations and in more detail.
Even when we cannot see it, the body keeps regulating itself all the time. What happens around it and within it can change its activity — heart rate, breathing, muscle tension. After those changes, the body may need different amounts of time to recover; sometimes, some physiological changes last even after the situation has ended. Research can measure some of these changes with instruments; watching someone in daily life is not enough to know how their regulation is being organized.
The readings are organized according to the framework we develop in Reading the Nervous System. The framework does not discover new mechanisms: it brings together what is known about these processes into a way of looking that follows time — what happened before, what built up, what opportunities there were between one demand and the next — and the conditions in which each person lives. It proposes that we ask questions about the conditions someone is in, about how they are organized within them — something we do not see directly — about what is within their reach at that moment, and about the different ways they can participate, some of which we may not recognize. And also about the relationship between the one who observes and the one being observed.
These categories help organize questions. They are not, in themselves, demonstrated physiological processes, nor do they describe a sequence that must always occur in the same order. Nor do they allow us to determine, by themselves, what explains a particular person's response. They help us look further back in time and in more detail at the conditions.
Some readings draw on what research has found; others develop what the framework proposes. In each one, we try to make the difference visible.
Each reading stands on its own. You can begin with whichever draws you most.
In the scene, you separated what you knew from what you assumed. This door takes that practice further: toward what happened before the visible moment, toward what the person might be communicating in other ways, and toward our own way of looking — what we expect to see and what our experience has taught us to consider important.

No response happens in a vacuum. This door looks at the environment: what is around the person, what is being asked, and what is expected. It does not take for granted how all of that affects the person living it.
Reading: Regulatory Margin in the Environment
Here the framework proposes four parameters for organizing questions about a person's experience and the conditions in which it takes place. They are conceptual tools to guide observation, not direct measures of what is happening inside that person.
Concurrent demand: what someone is already sustaining when something new arrives.
What was happening at the same time: sounds, tasks, other people? What do we know about their rest, eating, or discomfort from the person's own account or from other relevant sources? If the person expresses pain or discomfort, that needs to be attended to, not reinterpreted as merely a sign of load.
Regulatory margin: the room that remains, at a given moment, for activation to rise without exceeding what can be sustained.
What demands were already present when the new one arrived, and under what conditions were they asked to respond? This does not tell us how much margin they had.
Activation slope: how quickly activation rises when something does not match what was expected.
Was there something unexpected just before? What we see afterward does not tell us how quickly it rose.
Recovery: how quickly, and how far, activation returns toward the recovery reference after it has risen.
Between one demand and the next, was there time, and were there conditions, for rest? Having time does not mean having recovered.
And one question for all of them: What information would lead us to reconsider our interpretation?
Readings: What Is Regulation? (G·02) · Regulatory Margin (G·03)
That something does not happen does not mean it cannot happen. This door distinguishes between what a person knows or can do and what is within their reach at a particular moment and under particular conditions. Without forgetting that they may also choose not to.

If there is pain, discomfort, illness, or a risk to safety, that is attended to first, without waiting for anything that follows.
You do not need a final explanation to act with care. With what you do know, you can:
Understanding is not excusing. Nor does it require correcting every behavior: responding can also mean respecting a "no," offering support, or changing a condition.
These topics do not yet have readings of their own. We leave them here as questions, because they are part of what we want to learn to look at.
Participating is not only speaking, answering, or doing what is expected. It can also be watching, moving closer, moving away, choosing, refusing, or doing things at one's own pace.
The one who observes is also part of what is being observed. Our tone, our hurry, the way we ask or wait for an answer, and what we already think we know can change the situation we are trying to understand — although that, by itself, does not explain any particular response.
Not every question the framework raises has an answer yet. These are some that remain open — not as gaps to be hidden, but as a visible part of the work.
What relationship might there be between what we observe, a person's current conditions, and their accumulated experience? What other explanations would we need to consider before attributing it to their regulatory organization?
If we suspect that recovery has been insufficient across different moments, what information would we need to examine that possibility without ruling out others?
How might the state of the person providing support — their tiredness, their hurry, their own tension — relate to what happens in the interaction and to what they are able to notice? What would we need to investigate to find out, without assuming a mechanism?
When a person's own account of their experience does not match our reading, what place do we give it? What would have to change in the way we read for their perspective to be able to correct it?
How do we keep a reading through the framework from leading us to overlook something that needs attention in its own right, such as pain?
