Why Do People Behave the Way They Do? Understanding What Sits Beneath Behaviour

Someone raises their voice. They begin pacing, crying, repeating themselves, shutting down or pushing everyone away. You try to explain. They become more distressed. You add more detail, ask more questions or insist that they listen—and the situation grows.

In moments like these, the instinct to fix the problem quickly is understandable. But when someone is dysregulated, more reasoning is not always more helpful. The person may temporarily have less capacity to process language, consider consequences, solve problems or explain what they need.

If someone is dysregulated, first support safety and reduce what they have to manage. Settle your own body, use a calm tone and fewer words, lower avoidable demands and sensory input, give appropriate space, offer one or two genuine choices, and follow any established behaviour support or safety plan. Do not argue, lecture, shame or insist on resolving the issue at its peak. Wait until the person has enough capacity to reconnect, reflect and learn.

This is the central principle of this article: settle first, teach later.

Settling first does not mean ignoring unsafe behaviour, removing every boundary or giving a person whatever they demand. It means recognising that safety and regulation come before problem-solving. Once the moment has passed, we can explore what happened, understand what sat beneath the behaviour and build skills that may make a different response possible next time.

What Does It Mean When Someone Is Dysregulated?

Dysregulation describes a state in which a person is having difficulty managing their level of emotional or physical arousal in a way that supports what they need to do. Their feelings may be intense, their body may be highly activated or shut down, and the skills they can usually access may be harder to use.

Dysregulation is not a character flaw, and the word itself is not a diagnosis. It is a human experience that can happen to children and adults, with or without a diagnosed disability or mental health condition.

A person may become dysregulated when the demands of a situation feel greater than the skills, support or capacity available to them in that moment. Possible contributors include:

• fear, frustration, grief, shame, disappointment or anxiety
• pain, illness, hunger, thirst, fatigue or poor sleep
• sensory overload or an unmet sensory need
• unexpected change, uncertainty or loss of control
• difficulty understanding language or expressing a need
• too many instructions, questions, people or demands at once
• conflict, rejection, trauma reminders or feeling misunderstood
• a task that does not match the person’s current skills or capacity

The visible trigger may be small while the total load is large. A change of plan might appear to be the cause, but the person may also be tired, in pain, worried about something that happened earlier and struggling with the noise in the room. The final event may simply be more than their body can manage at that time.

This is why asking, “Why are you acting like this?” at the height of distress is rarely useful. The person may not know, may not be able to put the answer into words or may experience the question as one more demand.

What Can Dysregulation Look Like?

Dysregulation does not always look like shouting or aggression. Some people become more outwardly active. Others become quiet, still or disconnected. The same person may respond differently on different days.

These signs do not prove that a person is dysregulated, and one behaviour can have many explanations. Rocking or repeating words, for example, may be a person’s usual and helpful way of regulating rather than a sign that something is wrong. The most useful comparison is often with that individual’s usual communication, movement and behaviour.

People who know the person well may notice early signs before anyone else. A change in tone, a particular phrase, faster movement, repeated questions or a sudden loss of speech might signal that the person’s capacity is reducing. Responding at this earlier stage can be easier and less intrusive than waiting until distress reaches its peak.

Why “Settle First, Teach Later” Matters

Reasoning, learning and accountability all matter. Timing matters too.

When a person is highly distressed, they may find it harder to take in long explanations, remember instructions, shift attention, see another person’s perspective or generate alternatives. Repeating the rule more firmly does not necessarily restore those skills. It may simply add more noise, pressure or conflict.

Current guidance from NSW Health notes that it is not possible to reason or problem-solve effectively with someone who is enraged; settling the situation comes before dealing with the underlying concern. Guidance from the Raising Children Network similarly recommends safety, space, reduced sensory input, fewer words and waiting during an autistic meltdown.

Across FABIC’s clinician interviews, the same practical message appeared repeatedly:

• Do not “lock horns” with a person who is already dysregulated.
• A settled supporter is better able to see the person rather than react to the behaviour.
• Simple, concrete language is often more useful than a detailed explanation.
• When someone’s emotional cup is already full, even a well-meant response can become more for them to process.
• The difficult moment can become a learning opportunity later—but only when the person has capacity to engage.

The aim is not to force calm. It is to stop adding avoidable pressure and create conditions in which the person has a better chance of returning to a more settled state.

How FABIC’s Body Life Skills Program Applies to Dysregulation

The FABIC Body Life Skills Program provides a simple structure for understanding behaviour and supporting lasting change:

During peak dysregulation, the immediate focus is usually the BODY and safety: noticing the state, reducing pressure and supporting the person through the moment. Once the person is settled, we can explore the LIFE component with curiosity. What happened? What was difficult? What need was not met? The SKILLS work then happens proactively, at a pace matched to the person.

This prevents a common mistake: trying to complete all three steps while the person is least able to participate. A crisis is not the ideal classroom. The teaching belongs in a safer, more settled moment.

What to Do When Someone Is Dysregulated: A Step-by-Step Response

There is no script that suits every person. Age, communication, culture, disability, trauma history, sensory profile, relationship and immediate risk all matter. The following steps are general principles to adapt to the individual and any professional plan already in place.

1. Check Immediate Safety

Before trying to understand or discuss anything, look at the immediate risk.

• Is anyone in danger of being injured?
• Is the person near traffic, water, stairs, glass, weapons or another hazard?
• Can children, bystanders or unnecessary staff move away safely?
• Does the person have a known medical condition or could this be a medical emergency?
• Is there an existing behaviour support, crisis, health or safety plan to follow?

Where it is safe to do so, create distance from hazards and reduce the audience. Avoid crowding, cornering or making sudden movements. Do not improvise physical restraint. NDIS providers must follow the person’s authorised plan, organisational procedures and applicable restrictive-practice requirements.

If there is an immediate risk of serious harm, a medical emergency or a life is in danger, call Triple Zero (000).

2. Settle Your Own Body First

Before speaking, notice what is happening in you. Are you holding your breath? Raising your voice? Moving quickly? Feeling the need to prove a point or regain control?

A brief pause can change the interaction. If it is safe, soften your posture, release tension from your hands and jaw, slow your breathing and lower your volume. The Better Health Channel notes that slow diaphragmatic breathing can help reduce the body’s stress response.

Your calmness is not a performance and it does not guarantee that the other person will settle. It does help you make clearer decisions and reduces the chance that your own reaction will add another layer of threat, urgency or conflict.

If you are too activated to respond safely and another trusted, informed person is available, it may be appropriate to step back and let them take the lead.

3. Reduce the Amount the Person Has to Process

Look for anything that can be safely simplified:

• pause non-essential tasks and questions
• reduce noise, bright light and unnecessary movement
• ask extra people to move away
• have one person communicate rather than several people speaking at once
• move to a familiar or quieter space if the person wants this and it is safe
• make the next step predictable

Reducing a demand in the moment is not the same as permanently abandoning an expectation. It can be a temporary safety and regulation decision. The task, boundary or problem can be revisited later in a way the person can understand and participate in.

4. Use Fewer Words and Concrete Language

When someone has reduced processing capacity, a long explanation can feel like another demand. Use short sentences, one idea at a time, and then pause.

Instead of:

“I have already explained why we cannot do that, and if you would just listen to me and stop shouting, we could work this out.”

Try:

“You’re safe. I’m here.”

“One thing at a time.”

“We can talk later.”

“Quiet room or outside?”

The right words depend on the person. Some people find emotion labels helpful. Others experience “I can see you’re angry” as inaccurate or intrusive. Use the language, visuals, gestures, signs or communication system the person already understands. Allow extra processing time instead of repeating the same instruction immediately.

5. Connect Without Confronting

Show the person that you are paying attention without turning the interaction into a contest.

• Use a calm, respectful tone.
• Position yourself in a non-threatening way and respect personal space.
• Listen for the concern beneath the volume or repetition.
• Acknowledge what you can genuinely understand.
• Avoid insisting on eye contact.
• Do not demand an apology or confession during the peak of distress.

Connection may involve quiet presence rather than conversation. One FABIC clinician described the discipline of not adding more to a person whose emotional “cup” is already full. Sometimes the most supportive response is to remain available, say very little and give the person time.

6. Give Space—Without Abandoning the Person

Space can mean physical distance, silence, fewer people or a pause from the task. It does not necessarily mean leaving someone alone.

You might say:

“I’ll step back. I’ll stay nearby.”

“You don’t have to talk right now.”

“I’ll check in again in five minutes.”

Some people regulate best with a trusted person nearby. Others need privacy. Some welcome a hand to hold; others experience touch as painful or threatening when overwhelmed. Do not assume. Use known preferences and, where possible, ask before touching.

If the person asks for space and it can be provided safely, respect that request. If they cannot be left alone because of an immediate safety risk, maintain the least intrusive level of supervision possible and follow the relevant plan.

7. Validate the Experience While Keeping the Boundary

Validation means recognising that the person is having a real experience. It does not mean agreeing with every statement or accepting unsafe behaviour.

Both of these messages can be true:

• “I can see this change was really hard.”
• “I won’t let anyone be hit.”

Or:

• “You wanted more time, and stopping felt sudden.”
• “The tablet is still finished for now. We can look at the plan when we’re settled.”

A clear boundary should be brief, achievable and focused on safety. Repeating it many times, adding threats or listing every past incident is unlikely to help in that moment.

8. Offer One or Two Genuine Choices

Dysregulation can intensify when a person feels trapped, powerless or unable to predict what happens next. A small choice can restore some participation:

• “Would you like the door open or closed?”
• “Do you want me nearby or at the doorway?”
• “Headphones or quiet room?”
• “Water now or in a few minutes?”
• “Would you like words, pictures or no talking?”

Only offer options you can honour. Too many choices can create more work, and a disguised command is not a genuine choice. If the person cannot answer, pause rather than repeatedly asking.

9. Use Known Regulation Supports, Not Assumptions

Helpful supports are individual. They may include:

• a familiar person or familiar routine
• quiet, dim lighting or noise-cancelling headphones
• movement, pacing or safe stimming
• a sensory item, weighted item or preferred object where clinically appropriate
• music, drawing, water, a pet or another familiar activity
• visual schedules, written words or AAC
• slow breathing or grounding exercises—if the person finds these helpful

Do not assume that a commonly recommended strategy will suit everyone. Telling a person to take deep breaths, for example, can feel controlling or increase distress if breathing exercises are unfamiliar or uncomfortable. Regulation supports work best when they are identified with the person and practised before a crisis.

10. Wait for Capacity to Return

Silence can feel uncomfortable when we want the situation resolved, but recovery takes time. Watch for the person’s own signs that capacity is returning, such as slower breathing, softer posture, reduced repetition, renewed use of communication, accepting a familiar activity or showing interest in what happens next.

A quieter body does not always mean the person is ready to talk. They may be exhausted, embarrassed or still processing. Ask simply:

“Do you want to talk now, later or not today?”

If the answer is later, honour that—and make sure “later” does not quietly become “never” when an important safety or relationship issue still needs repair.

Helpful Phrases—and What Can Add More Pressure

These are examples, not scripts. A phrase that reassures one person may irritate another. The goal is to understand the individual’s communication preferences and agree on helpful language before the next difficult moment.

What If the Person Is Aggressive, Self-Injuring or at Risk of Harm?

Dysregulation and dangerous behaviour are not the same thing, but they can occur together. If there is aggression, self-injury or another serious risk, safety takes priority.

• Keep a safe distance and a clear way for yourself to leave.
• Move other people away where this can be done safely.
• Reduce access to hazards only if you can do so without increasing risk.
• Use one calm communicator and avoid arguing, threatening or crowding.
• Follow the person’s behaviour support, crisis or medical plan.
• Seek trained assistance early rather than waiting until the situation exceeds your capacity.

Do not attempt an improvised restraint or use seclusion as a convenient calming strategy. A quiet space the person chooses and can freely leave is different from preventing them from leaving. For NDIS-funded supports, regulated restrictive practices are subject to legal safeguards. The NDIS Quality and Safeguards Commission states that behaviour support should help others understand why behaviour occurs and how to support the person’s needs. Any regulated restrictive practice must be authorised where required, used only as a last resort, be proportionate to risk, be the least restrictive option and be used for the shortest possible time.

If a life is in danger, there is an immediate risk of serious injury or urgent medical care is required, call Triple Zero (000). If someone is in emotional crisis or thinking about suicide, Lifeline is available in Australia 24 hours a day on 13 11 14; call 000 if life is in immediate danger.

Supporting an Autistic or Non-Speaking Person Through Dysregulation

Autistic people may experience dysregulation or meltdown when sensory, emotional, communication or situational demands become overwhelming. A meltdown is not simply “bad behaviour”, and it should not automatically be treated as a deliberate attempt to gain control.

Useful considerations may include:

• reduce noise, lighting, conversation and the number of people present
• do not stop safe stimming that is helping the person regulate
• avoid touch unless the person has indicated that touch is helpful
• do not insist on eye contact
• keep access to AAC, visual supports, writing or gestures available
• allow extra time for processing and responding
• do not assume that lack of speech means lack of understanding
• use the person’s known sensory and communication profile rather than a generic “autism strategy”

A speaking person may temporarily lose reliable access to speech when overwhelmed. Continue to communicate respectfully and offer accessible alternatives without demanding a response.

Every autistic person is different. The Australian national guideline for supporting autistic children and their families emphasises support that is effective, safe and desirable to the child and family. Personal preference, consent, communication and lived experience should shape the plan.

What Not to Do When Someone Is Dysregulated

Even well-intended responses can increase pressure. Unless immediate safety requires otherwise, avoid:

• Arguing about facts: Proving that the person is mistaken rarely settles an activated body.
• Asking many questions: Questions require processing and can feel like interrogation.
• Giving a lecture: Save explanations, consequences and skill-building for later.
• Matching intensity: Louder voices, quick movements and hostile posture can increase threat.
• Taking the behaviour personally: This makes it harder to remain curious and respond to what is needed.
• Shaming or labelling: Words such as “naughty”, “manipulative”, “dramatic” or “attention-seeking” do not explain the behaviour and can damage trust.
• Demanding eye contact, touch or speech: These can add significant pressure.
• Making threats you cannot or should not carry out: This reduces safety and predictability.
• Offering too many solutions: Choose one simple next step and allow time.
• Talking about the person as if they are not there: Preserve dignity even when their communication looks different.

Also avoid assuming that every incident is “behavioural”. A sudden or unusual change can be related to pain, illness, injury, medication, sleep or another health issue. Seek medical advice when indicated, particularly if the change is abrupt, severe or out of character.

What to Do After the Person Is Settled

The period after dysregulation is where connection, learning and prevention can begin. It should not become a delayed punishment session.

1. Support Recovery Before Debriefing

The person may need water, food, rest, quiet, movement, a familiar activity or time without conversation. Check for injury or illness. Restore dignity and privacy, particularly if the incident happened in front of other people.

2. Reconnect Without Shame

A simple message can protect the relationship:

“That was a hard moment. I’m glad you’re here. We can work out the next step together.”

Separating the person from the behaviour is central to the FABIC ethos and principles of client care. The behaviour may need to be addressed, repaired or changed; the person still deserves decency, respect and dignity.

3. Ask What Happened in an Accessible Way

When the person is ready, use curiosity rather than accusation:

• “What felt hardest?”
• “When did you first notice your body changing?”
• “Was it the noise, the change, the task, something else—or are you not sure?”
• “What did you need that you could not ask for?”
• “What helped, and what made it harder?”
• “What would you like us to do differently next time?”

Not everyone can explain the reason, and memory may be incomplete after intense distress. Use visuals, drawing, AAC, yes/no options or observation when these are more accessible. Treat everyone’s explanation—including your own—as information to explore, not an unquestionable conclusion.

4. Repair Harm Without Defining the Person by It

If someone was hurt, frightened or had property damaged, repair may still be needed. The conversation can include responsibility while avoiding shame:

• describe what happened clearly
• acknowledge the impact
• identify what can be repaired now
• agree on a safer alternative for next time
• practise that alternative when the person is settled

Understanding why a behaviour occurred does not excuse harm. It makes the response more useful because it addresses both the impact and the missing support or skill.

5. Record the Pattern Objectively

For repeated incidents, record what a camera could have observed:

Patterns across time are more informative than a confident guess after one incident. The information can also help a behaviour support practitioner assess what is contributing to the dysregulation and which strategies should be tested. Learn more about Functional Behavioural Assessments and the Body Life Skills Program.

6. Teach and Practise the Missing Skill

The alternative needs to be realistic and useful. Depending on what happened, this might involve teaching the person to:

• recognise early body signs
• ask for help, information, connection, space or a break
• use AAC or a visual card under stress
• cope with waiting or a small change in plan
• use a preferred regulation strategy
• communicate “no” or negotiate a demand safely
• repair a relationship after conflict
• choose between two safe options

Practise when the person is settled, start small and adjust the task to their capacity. A new skill is unlikely to replace an established behaviour unless it works reliably enough to meet the person’s need.

Create a Personal Regulation and Response Plan

The best time to decide what helps is before the next crisis. Develop the plan with the person wherever possible—not only about them.

A useful plan may describe:

• the person’s usual settled presentation
• their early signs of rising stress
• common situations that reduce capacity
• health, sensory and communication considerations
• words, visuals, gestures or AAC that help
• words, touch, people or approaches that make things harder
• preferred spaces and regulation supports
• how much proximity or supervision is needed
• clear responses to different levels of risk
• who should be contacted and when
• what recovery and debriefing look like for that person

For NDIS participants with behaviours of concern, these strategies may form part of a formal behaviour support plan. The NDIS Commission’s current Behaviour Support Assessment—including Functional Behaviour Assessment Guide emphasises person-centred, proactive and evidence-informed strategies, environmental change, skill development and clear response strategies.

A plan is only useful if the support team understands it and applies it consistently. Training, rehearsal and review matter—especially when several family members, educators, carers or support workers are involved.

Looking After the Person Who Is Providing Support

Supporting repeated or high-intensity dysregulation can be exhausting. It may leave parents, partners, carers and workers frightened, angry, guilty or constantly alert for the next incident.

FABIC clinicians repeatedly described the supporter’s own foundations as part of effective care. When we are depleted, we are more likely to react, personalise behaviour or lose sight of the person beneath it. This is not a reason to blame an overwhelmed supporter. It is a reason to include their needs in the plan.

Helpful supports may include:

• clear roles during an incident
• access to relief, respite or another trained person
• debriefing and supervision after serious events
• sleep, food, movement and other basic foundations
• training in the person’s plan and communication
• permission to step back when another safe supporter can take over
• professional support for the supporter’s own stress or trauma

You do not need to be perfectly calm to help. You do need enough support and preparation to respond safely and respectfully.

When Should You Seek Professional Support?

Professional support may be helpful when dysregulation:

• is frequent, prolonged or becoming more intense
• creates a risk of harm to the person or others
• involves aggression, self-injury, property damage or leaving unsafe environments
• affects relationships, education, work, housing or community participation
• is difficult to understand despite strategies already being tried
• may be linked with complex communication, sensory, health or trauma factors
• leaves the person or their support team feeling unsafe or unable to cope
• may lead to the use of restrictive practices

A sudden or significant change should also prompt consideration of pain, illness, medication effects, sleep, mental health or another medical issue. A GP or relevant health professional can help assess these possibilities.

A FABIC Behaviour Support Practitioner can work with the person, family and support team to understand patterns, complete assessment where appropriate, develop proactive and in-the-moment strategies, and teach skills for lasting change. FABIC offers support in multiple Australian locations and through telehealth, subject to individual suitability and service availability.

Frequently Asked Questions About Dysregulation

How Do You Help Someone Who Is Emotionally Dysregulated?

Start with safety and reduce pressure. Settle your own body, speak calmly and briefly, reduce avoidable demands and sensory input, give appropriate space, offer simple choices and use supports already known to help the person. Do not force problem-solving at the peak. Reconnect, understand and teach later when capacity has returned.

What Is Co-Regulation?

Co-regulation is the support one person offers another as they manage emotion and arousal. It can involve a steady presence, predictable communication, validation, modelling, sensory or environmental support and help using an existing regulation skill. Co-regulation is not taking control of someone’s emotions or guaranteeing that they become calm.

Should I Tell a Dysregulated Person to Calm Down?

Usually, “calm down” does not tell the person how to do so and may make them feel misunderstood or controlled. A more useful response is to reduce what they must process and offer one specific support, such as space, quiet, water, a familiar regulation tool or a simple choice.

Should I Ask Why They Are Upset?

Not repeatedly at the height of distress. The person may not have access to the answer or the words. Wait until they have more capacity, then ask in an accessible way and accept “I don’t know” as valid information. Patterns across several incidents may reveal more than one immediate explanation.

Does Reducing a Demand Reward the Behaviour?

Not necessarily. Temporarily reducing a demand may be needed for safety and regulation. However, if the same pattern occurs repeatedly, it is important to understand why. The task may be inaccessible, the person may need a reliable way to request a break, or the response may unintentionally maintain the behaviour. A functional assessment can help determine the right proactive and teaching strategies.

Can I Keep a Boundary While Being Empathetic?

Yes. You can recognise the person’s distress and still maintain a clear safety boundary. For example: “I can see this is hard. I won’t let anyone be hit. I’m stepping back, and we can talk when it is safer.” Empathy helps you understand the experience; it does not require accepting harm.

How Long Does Dysregulation Last?

There is no universal timeframe. It depends on the person, the intensity of the situation, health and sensory factors, what happens around them and whether further demands are added. A person may look quiet before they are ready to talk, and recovery can continue after the visible behaviour stops.

What If the Person Will Not Talk Afterwards?

Do not assume refusal or lack of understanding. They may need more time or another communication method. Offer writing, visuals, AAC, simple choices or a later check-in. Some information may need to come from careful observation and patterns over time, while still including the person’s preferences and communication wherever possible.

Is Dysregulation the Same as an Autistic Meltdown?

No. Dysregulation is a broad description of difficulty managing emotional or physiological arousal. An autistic meltdown is one possible expression of overwhelm in an autistic person. Not every dysregulated person is autistic, and not every sign of distress in an autistic person is a meltdown. Individual assessment and the person’s own experience matter.

A Final Thought: The Lesson Can Wait

When someone is dysregulated, it is easy to focus entirely on stopping what we can see. But the fastest-looking response is not always the one that creates lasting change.

First, support safety. Bring less pressure, not more. See the person rather than taking the behaviour as their identity. Use fewer words. Give time. Follow what is known to help.

Then, when capacity returns, become curious. What part of life felt too difficult? What was the body communicating? What support, environmental change or skill could make the next moment different?

Settle first. Connect next. Understand and teach later.

Would You Like Help Supporting Dysregulation?

If dysregulation is affecting safety, relationships, learning, independence or everyday life, you do not have to work it out alone. FABIC’s team works with individuals, families and support communities to understand what sits beneath behaviour and develop practical, person-centred strategies for lasting change.
