Behaviour & Regulation Glossary (A–Z)

Clear, respectful definitions for behaviour support, emotional regulation, and everyday coping language.

Welcome

Behaviour is communication

This glossary explains common terms used in behaviour support and regulation conversations (home, school, disability support, and therapy settings) — in calm, plain language.

✔ Strengths-based ✔ Neurodiversity-affirming ✔ Trauma-aware ✔ Practical examples

“Support helps skills grow — not shame.”

Gentle content note

Some terms describe distress, safety, and crisis support. Definitions are written to be educational and non-graphic. You can use the search bar, skip sections, or take breaks — there is no rush.

Tip: Search filters the terms live as you type.

Quick model

The ABC Framework (simple)

A helpful way to notice patterns — without blaming the person.

Part	What it means	Gentle example
Antecedent	What happened before the behaviour	The room got loud and busy.
Behaviour	What the person did (what we can observe)	Covered ears, left the space, yelled “stop”.
Consequence	What happened after (response/impact)	Adult offered quiet space + headphones; noise reduced.

Regulation supports

Co-regulation toolkit

Support that helps the nervous system settle (then skills can happen).

Support	When it helps	Why it helps
Predictability	Transitions, new places	Reduces uncertainty + threat signals
Low words	Overwhelm, shutdown, meltdown	Less processing demand
Choice	Power struggles / stuck moments	Restores control safely
Sensory tools	Noise/light/touch overload	Supports regulation through the body

Letter A

Accommodation: Changes that reduce barriers so someone can participate and learn. Example: “Movement breaks help me focus and stay regulated.”
Activation (nervous system): When the body shifts from calm into “ready” mode (more alert, more energy). Example: “I noticed my activation rising, so I used breathing and a quiet corner.”
Antecedent: Something that happens right before a behaviour (a trigger, change, demand, or environment). Example: “The antecedent was the sudden change in plan.”
Augmentative & Alternative Communication (AAC): Ways of communicating that aren’t speech-only (pictures, device, typing, sign). Example: “AAC helps me communicate when words are hard.”
Autonomy: Having control over your body and choices. Example: “Offering options supports autonomy and reduces stress.”

Letter B

Behaviour (as communication): What we do to meet a need (comfort, safety, help, space, connection). Example: “Leaving the room was a way to communicate ‘too much’.”
Behaviour Support Plan (BSP): A plan that focuses on prevention, skill-building, and supportive responses. Example: “The BSP includes visual schedules and calm-down options.”
Body cues: Signals in your body that show stress or calm (tight chest, shaky hands, relaxed shoulders). Example: “My jaw tightens when I’m getting overwhelmed.”
Boundary: A limit that protects wellbeing and safety. Example: “I’m not ready to talk — I can message later.”
Break (planned): A supportive pause built into routines to prevent overload. Example: “A planned break stops stress from building too high.”

Letter C

Co-regulation: When another person helps you regulate through calm presence, structure, and safety. Example: “A steady voice helped my body settle.”
Calm corner: A safe space with tools for regulation (low light, fidgets, water, headphones). Example: “I used the calm corner before my stress hit 10/10.”
Capacity: How much energy/ability you have for demands right now. Example: “My capacity is low today — I’m choosing smaller tasks.”
Consequences (in behaviour terms): What happens after a behaviour; can increase or reduce the chance of it happening again. Example: “Reducing noise after overload reinforced leaving early.”
Choice architecture: Offering options that are all acceptable and supportive. Example: ‘Do you want the quiet table or the hallway break?’

Letter D

De-escalation: Support that helps stress reduce (space, fewer words, calm tone, predictable steps). Example: “We de-escalated by lowering demands and offering water.”
Demand: Anything that requires effort (instructions, transitions, social expectations). Example: “Too many demands can push my regulation down.”
Dysregulation: When the nervous system is overwhelmed and coping is harder. Example: “When dysregulated, I need support — not lectures.”
Distress tolerance: Skills that help you ride out intense feelings safely. Example: “Cold water + paced breathing helps me tolerate distress.”
Downshift: Moving from high alert toward calm (slower breathing, softer muscles). Example: “After the break, my body downshifted.”

Letter E

Emotion coaching: Helping someone name feelings and choose coping steps without judgement. Example: “I can see you’re frustrated — let’s breathe together.”
Emotional regulation: Skills and supports that help feelings become manageable. Example: “I regulate through movement and predictable routines.”
Executive function: Brain skills for planning, starting, switching, remembering, and stopping. Example: “Task initiation is hard — a visual checklist helps.”
Escalation: When stress increases (more intensity, less access to words/skills). Example: “Early support prevents escalation.”
Environment (as support): Adjusting noise, lighting, space, and expectations to help regulation. Example: “Dim lights reduced sensory stress.”

Letter F

Fight / Flight / Freeze / Fawn: Common stress responses (protective survival patterns). Example: “Freeze can look like ‘not responding’ — it’s a stress response.”
Functional communication: Communication that effectively meets a need (help, break, “no”, “more time”). Example: “A break card is functional communication.”
Function of behaviour: The “why” — what the behaviour helps the person achieve or avoid. Example: “The function might be escape from overload.”
Flexibility (skill): Ability to adapt when plans change; can be hard under stress. Example: “We practiced flexibility with small, predictable changes.”
Fidget: Small movement/tool that supports focus and regulation. Example: “Using a fidget helps me stay present.”

Letter G

Grounding: Skills that bring attention back to the present using the senses. Example: “I name 5 things I can see to ground myself.”
Guilt (after dysregulation): A common feeling after an intense moment; support focuses on repair and learning. Example: “I used repair steps instead of shame.”
Goal (behaviour support): A skill we build (communication, coping, transitions) instead of just stopping behaviour. Example: “Goal: ask for a break using a card.”
Generalisation: Using a skill across places/people (home + school). Example: “We practiced coping skills in different settings.”

Letter H

Helping words: Short phrases that reduce stress and guide next steps. Example: “You’re safe. One step. I’m here.”
High arousal: Body is “on” (fast heart, restless, intense emotion). Example: “High arousal needs calming supports before learning.”
Headphones / sensory protection: Tools that reduce sensory load. Example: “Headphones helped me stay in class.”
Hyperfocus: Deep focus that makes switching tasks harder. Example: “I needed a 5-minute warning to shift out of hyperfocus.”

Letter I

Interoception: Sensing internal body signals (hunger, thirst, stress, needing the toilet). Example: “Low interoception means I miss early stress signs.”
Impulse control: Ability to pause before acting; gets harder under stress. Example: “When dysregulated, my impulse control drops.”
Inclusion: Adjusting spaces and expectations so people can belong as they are. Example: “Inclusion means access, not forced sameness.”
Initiation (task start): Starting a task; can require support like prompts and breaking steps down. Example: “A first-step cue helps with initiation.”

Letter J

Joint attention: Sharing focus on the same thing with another person (look, point, comment). Example: “Joint attention can be supported with low-pressure play.”
Journaling (regulation tool): Writing or drawing to process feelings and track patterns. Example: “I journal to notice triggers and helpful supports.”
Just-right challenge: Tasks that are not too easy or too hard (supports skill-building without overwhelm). Example: “We adjusted demands to a just-right level.”

Letter K

Key worker (support role): A main contact person who helps coordinate support. Example: “My key worker helps keep plans consistent across services.”
Kid-led / person-led approach: Following the person’s interests and signals to build trust and regulation. Example: “We used a person-led approach to reduce pressure.”
Kind prompts: Supportive cues that guide without shaming. Example: “First shoes, then outside.”

Letter L

Lagging skills: Skills that are still developing (flexibility, frustration tolerance, language). Example: “We support lagging skills with teaching and practice.”
Low demand: Reducing pressure temporarily to support recovery and regulation. Example: “Low-demand time helped my nervous system reset.”
Learned safety: When the body begins to expect safety in a place/person over time. Example: “Consistent calm responses build learned safety.”

Letter M

Meltdown: An overload response where control is reduced; it’s not a choice or “bad behaviour”. Example: “A meltdown means I need safety and recovery time.”
Mind-body regulation: Using body-based supports (movement, breathing, pressure) to help emotions. Example: “Heavy work helps my body feel settled.”
Motivation: What makes a task feel possible/meaningful; stress reduces motivation. Example: “When supported, motivation returns.”
Micro-break: A tiny pause to prevent overload (30–90 seconds). Example: “A micro-break stopped escalation.”

Letter N

Need (under behaviour): The reason a behaviour happens (safety, connection, sensory relief, communication). Example: “The need was escape from overload, not attention.”
Nervous system: The body’s safety system that shifts between calm, alert, and overwhelmed. Example: “Support helps my nervous system feel safer.”
Neurodiversity-affirming: Support that respects differences without trying to “fix” identity. Example: “We focus on comfort and access, not masking.”
Nonverbal communication: Communication without speech (gestures, AAC, movement, facial expression). Example: “My body language says ‘too much’ before words do.”

Letter O

Overwhelm: When demands or sensory input exceed capacity. Example: “Overwhelm looks like shutting down or leaving.”
Override (stress override): When stress reduces access to thinking skills. Example: “In stress override, I need fewer words and more safety.”
Options (supportive): Choices that reduce power struggles and increase control. Example: “Do you want a break now or after one more step?”

Letter P

Predictability: Knowing what happens next; supports safety and regulation. Example: “A visual schedule made the day feel predictable.”
Prompt: A cue that supports a skill (visual, gesture, first-step). Example: “A visual prompt helped me remember the steps.”
Positive reinforcement: When something helpful increases the chance of a skill happening again (praise, break, preferred activity). Example: “After asking for help, they got support quickly.”
Processing time: Extra seconds/minutes needed to understand and respond. Example: “I need processing time before I can answer.”

Letter Q

Quiet space: A low-stimulation area for regulation and recovery. Example: “A quiet space helped me return to baseline.”
Quick reset: A brief strategy to reduce stress (water, breathing, pressure, fresh air). Example: “A quick reset stopped my stress climbing.”
Quality of support: How consistent, respectful, and safe the support feels. Example: “Better support quality reduced my anxiety.”

Letter R

Regulation: Being in a state where coping and thinking are more accessible. Example: “When regulated, I can learn and problem-solve.”
Repair: Steps after a tough moment to rebuild connection and safety. Example: “We repaired by apologising, resting, and making a plan.”
Routine: Predictable pattern that reduces decision load and stress. Example: “A morning routine helps my nervous system feel safe.”
Rejection sensitivity: Strong emotional response to perceived criticism or rejection. Example: “Gentle feedback supports me when I’m sensitive to rejection.”

Letter S

Safety plan: A personal plan for intense moments: warning signs, supports, safe people, and help options. Example: “My plan is saved on my phone.”
Sensory overload: When sensory input becomes too much (noise, light, touch). Example: “Overload makes it hard to speak or stay.”
Shutdown: A protective response where the body “powers down” (quiet, withdrawn, slowed). Example: “Shutdown means I need time, low words, and safety.”
Stimming: Self-stimulating movement/sound that supports regulation and focus. Example: “Stimming helps me stay calm and organised.”
Support needs: The kind of help a person requires to access everyday life. Example: “Support needs can change day to day.”

Letter T

Transition: Moving from one activity/place to another; can be hard under stress. Example: “A warning timer helps transitions.”
Trigger: Something that sparks a strong stress response (sensory, memory, demand). Example: “Sudden shouting is a trigger for me.”
Time-in (not time-out): Staying connected and supported during distress rather than isolating. Example: “Time-in helped me settle faster.”
Trauma-aware: Support that assumes distress may be linked to past experiences and prioritises safety and choice. Example: “We use consent-based support.”

Letter U

Up-regulation: Strategies that increase alertness when energy is low (movement, light, music). Example: “A brisk walk helps me up-regulate.”
Unmet need: A need that hasn’t been supported yet (rest, sensory relief, clarity). Example: “The behaviour showed an unmet need for a break.”
Urgent support: When someone needs immediate help for safety or crisis. Example: “If I feel unsafe, I contact urgent support options.”

Letter V

Validation: Letting someone know their feelings make sense, even if behaviour needs support. Example: “I see this is hard. I’m here.”
Visual supports: Pictures or written cues that reduce processing load. Example: “Visual steps helped me complete the task.”
Voice (tone): How we speak can increase or reduce stress. Example: “A calm tone helped me feel safer.”

Letter W

Weighted pressure: Deep pressure that can support calm (only if the person likes it). Example: “A weighted lap pad helps me settle.”
Window of tolerance: The zone where coping and thinking are more accessible; stress pushes us above/below it. Example: “Breaks help me stay in my window of tolerance.”

Letter X

X-factor (individual differences): Personal factors that shape regulation (sleep, pain, stress, sensory needs). Example: “My X-factor today is poor sleep, so I need more support.”

Letter Y

Yes-set: Starting with easy, agreeable steps to build momentum. Example: “First one easy step, then the harder one.”
Your pace: Respecting the person’s speed for processing, calming, and responding. Example: “Supporting my pace helps me stay regulated.”

Letter Z

Zone of regulation: A way to describe energy/emotion states (calm, alert, overwhelmed) to support coping tools. Example: “I’m in a high-energy zone — I need movement then breathing.”
