Polyvagal-Informed Sandtray

The three states, briefly

Polyvagal Theory (PVT) describes three branches of the autonomic nervous system that organize our response to safety and threat (Porges, 2011, 2017). Deb Dana's clinical translation of PVT is the version most counselors learn first (Dana, 2018):

• Ventral vagal — social engagement. The state of safety. Eye contact softens, voice has prosody, breath is even, the body is open. Connection feels possible.
• Sympathetic — mobilization. The state of action. Heart rate rises, attention narrows, movement is rapid. Fight or flight; or, in less acute form, anxious doing.
• Dorsal vagal — immobilization. The state of shutdown. The body slows; affect flattens; the gaze goes far away. Freeze, dissociation, collapse.

Porges introduced neuroception to describe how the nervous system non-consciously scans for cues of safety, danger, or life threat — and shifts state without waiting for the prefrontal cortex to weigh in (Porges, 2011). For trauma-informed work, this is the central insight: state precedes story.

What each state looks like in the tray

Ventral signs (the "green" zone)

Trays built from ventral activation tend to have organization, narrative, and aesthetic care. The client makes considered figure choices, may name what they're building, makes brief eye contact, breathes audibly. The pacing is unhurried. Clients in ventral can hold both/and — they can place a worry figure next to a comfort figure.

Sympathetic signs (the "yellow" zone)

Mobilized trays often look chaotic, rushed, or aggressive. Figures are knocked over, bunched in piles, or hurled into corners. Builds and demolishes follow quickly. Speech may speed up; breath shortens. With younger clients, mobilization can present as silly, over-active play that escalates. Important: sympathetic activation in the tray is not pathology. The body is moving energy that needs to move. The clinical question is whether it can move through and resolve, or whether it spirals (Dion, 2018).

Dorsal signs (the "blue" zone)

Shutdown trays may be sparse, empty, or built without expression. The client may pick up figures and put them down without affect; choices feel mechanical or compliant. Eye contact is averted; voice is monotone; body posture collapses. Builds may be tidy in a way that feels lifeless rather than calm. Dorsal can be subtle — a polite, helpful client who is not actually present.

Mixed and blended states

Real sessions rarely sit cleanly in one state. PVT describes blended states — most relevant to the tray are ventral-with-sympathetic (engaged play, healthy aggression in service of a story) and ventral-with-dorsal (stillness, reverence, contemplation). These blends are often where the work happens. Pure sympathetic and pure dorsal are not therapeutic states; they are dysregulated ones (Dana, 2018).

Tracking state across a session

A polyvagal-informed clinician tracks state shifts the way a Kalffian clinician tracks symbolic emergence. You are watching the client's autonomic narrative. Useful questions to hold internally:

• What state did the client arrive in?
• What state did the tray work move them toward?
• Where did the shift happen — and what supported it (a figure choice, a moment of co-regulation, a pause)?
• What state did they leave in? Were they in a state safe enough to walk back into their day?

The Session Note Template includes a polyvagal-coded affect field so you can document this efficiently and review patterns across sessions.

Co-regulation: the clinician's nervous system as instrument

PVT describes how regulated nervous systems calm dysregulated ones through proximity, prosody, facial expression, and breath. This phenomenon — co-regulation — is the mechanism behind why presence is therapeutic (Geller & Porges, 2014; Badenoch, 2018).

Practically, this means your own state during the session is part of the intervention. If you arrive depleted, in sympathetic activation, or in low-grade dorsal, the client's nervous system will neurocept that. A few minutes of grounding — breath, feet on the floor, a brief contact with something that brings you to ventral — before opening the tray is not self-care window-dressing. It is clinical preparation.

Use in a session

Opening

Begin by reading the client's state, not by gathering information. A simple "How are you arriving today?" with patient eye contact tells you more than a check-in form. If they're sympathetic, slow your own pace and lower your voice. If they're dorsal, increase warmth and prosody — gently — without demanding engagement.

Choosing your stance based on state

• If the client is ventral-leaning: trust the process. Offer the tray and step back. Insight, narrative, and symbolic work are accessible.
• If the client is sympathetic: the tray itself is regulating. Allow movement, building and unbuilding, knocking over. Resist the urge to slow it down prematurely. Watch for the moment activation begins to settle — that is when meaning-making becomes possible.
• If the client is dorsal: do not push for content. Bottom-up first: warm voice, soft eyes, perhaps a sensory invitation ("Notice the texture of the sand for a moment, before we do anything else"). The first goal is autonomic shift, not a finished tray.

During the build

Notice state shifts as they happen and make brief, regulating contact across them — a soft "Mmm", a nod, a present silence. These are co-regulating signals; they are not interpretations. Save your symbolic curiosity for after the session.

Closing

Always close with attention to the state the client is leaving in. If they are still sympathetic or dorsal, do not send them out. A short grounding moment — a breath together, naming three things in the room, a regulating goodbye — is part of the intervention, not an afterthought (Dana, 2018).

What's different in the digital tray

Co-regulation across a screen is real but attenuated. Three things help:

• Camera at eye level. The non-conscious face-to-face cues PVT describes only work if your face is visible at a natural angle. A laptop on a desk usually shoots up your nose; raise it.
• Prosody. Voice carries autonomic information faster than image. Speak with warmth and unhurried rhythm; clip your sentences less.
• Don't multitask. Even a glance at email is detectable. Close other tabs. The session is the session.

Working with mobilization that escalates

Sympathetic activation in play can intensify quickly, especially in younger clients. Lisa Dion's work on aggression in play therapy is the most useful clinical writing on this topic and pairs well with PVT (Dion, 2018). Three rules of thumb:

• Stay in your own ventral. If you start mirroring the client's escalation, the work tips into dysregulation for both of you.
• Set boundaries, not lectures. Brief, calm limits on safety ("In here, the figures stay in the tray") preserve the frame without breaking it.
• Watch for the threshold. Sympathetic activation that moves through a story is regulating. Sympathetic activation that stays stuck in repetition is not. The latter often means the client's window of tolerance has been exceeded; pull back to bottom-up regulation.

Documenting polyvagal observations

Polyvagal language is increasingly accepted in clinical documentation, but framing matters. Useful phrasings:

• "Client arrived in sympathetic activation, evidenced by rapid speech and elevated motor activity. Tray work supported a shift toward ventral, evidenced by slowed pace, organized figure placement, and sustained eye contact during the closing."
• "Predominantly dorsal presentation throughout the session. Bottom-up regulation prioritized; symbolic work deferred."

Avoid jargon-heavy notes that an external reviewer cannot follow. The Session Note Template uses plain-language polyvagal coding (green / yellow / blue) that is interpretable across disciplines.
