Using Secure Functioning to enhance Somatic Experiencing

What each one is actually for

Secure Functioning

Secure functioning is trying to make two people predictable to each other under load. The agreements a PACT couple makes are not about being nicer; they are about what happens at the specific moments when neither person is at their best — the first thirty seconds of a rupture, the return after one of you has gone quiet, the transition home from a day that went badly. Tatkin's argument is that a relationship in which those moments are improvised will drift toward each partner privately managing their own threat state, because that is what a body does when it cannot predict the other one. The agreements exist to make the other person's next move knowable, which is a physiological service as much as a moral one. When you know what your partner will do when you are upset, your body has less to track.

Somatic Experiencing

Somatic Experiencing is trying to let a stress response finish. Levine's starting observation was that a threat response in the body runs a natural arc — mobilise, act, discharge, settle — and that in people it very often gets interrupted partway, leaving the mobilised part held in the body rather than completed. The practice works at the level of raw sensation rather than story: where in your body, what quality, does it have an edge or a centre, is it moving. Two things keep it from becoming overwhelming. Titration means taking a small enough dose of the sensation that you never leave the range you can tolerate. Pendulation, the other core move, means deliberately moving your attention back and forth between the activated place and somewhere in the body that currently feels neutral or fine, which keeps the nervous system from getting stuck in the difficult part. Signs the arc is completing are physical and often unremarkable: a spontaneous deeper breath, a wave of heat, the hands going warm, a small shake, tears that arrive without a story attached.

What you get out of pairing them

There is a version of we're fine that your shoulders do not believe. You made up an hour ago and you both meant it, and yet you are still slightly braced, still faintly on guard, and by ten o'clock you will have been curt about something unrelated and neither of you will connect it to the afternoon. That residue is what this pairing goes after. Not the argument — the tail of the argument, which is where a surprising amount of the damage in a long relationship accumulates, one unfinished afternoon at a time. What you stand to get is a body that actually comes down when the conversation ends, in the same hour rather than two days later, and a partner who can tell the difference between you being difficult and you being unfinished. There is a second thing, less obvious and more valuable. Once you have felt your own system settle in your partner's presence a few times, the relationship starts to register as a place where settling happens, which is a slower change than any single technique and the one people are really after.

What Secure Functioning rests on

• Attunement requires active monitoring not good intentions clinical practice
  Staying attuned to a partner's internal state requires ongoing structured attention rather than goodwill alone because connection erodes by default without it.
• Explicit commitment changes daily priority weighting clinical practice
  Explicitly and mutually committing to protect the relationship above other priorities changes how partners weigh choices during ordinary daily conflict.
• Rituals of connection reduce reliance on spontaneous attunement practitioner report
  Building repeatable rituals of connection reduces dependence on spontaneously noticing a partner's needs in the moment.

What Somatic Experiencing rests on

• Interoceptive attention randomised trials
  Directing sustained attention to internal bodily sensations increases awareness of the body's state and changes how that state is experienced.
• Graded exposure reduces avoidance randomised trials
  Repeatedly approaching a feared or avoided stimulus or action within a controlled, tolerable structure reduces the fear and avoidance response it triggers.
• Somatic discharge completes stress cycle clinical practice
  Physically completing a build-up-then-release cycle in the body discharges stored tension rather than leaving it held.

Where they actually meet

Safety is the word both traditions reach for, and they mean two different layers of the same thing. PACT builds safety as a set of terms between two people: an explicit, mutual commitment that changes how each of them weighs a choice at eleven at night, backed by agreements that do not depend on either partner spontaneously noticing what the other needs. Somatic Experiencing builds it inside one nervous system: small tolerable doses of sensation, approached rather than avoided, until a body that has been braced against something can stop bracing. The reason those two layers belong on the same page is that the second one does not automatically follow from the first. You can be objectively safe, correctly informed that you are safe, and married to someone who has kept every agreement, and still be sitting there with your jaw set — because the part of you doing the bracing does not take verbal instruction. What each practice supplies is what the other one assumes. PACT assumes that if the agreements hold, the settling will follow, and often it does not without something aimed at the body. Somatic Experiencing assumes a setting safe enough for a person to stop guarding, and for a couple that setting is not a given; it is a thing they either built or did not.

The principle underneath both

Approach in small doses beats confrontation, and both practices are organised around that. Levine's titration is the explicit version — never take on more sensation than your system can stay with, because exceeding that range does not speed anything up, it simply re-teaches the body that turning inward is dangerous. PACT's version is less obviously the same thing until you look at what its agreements do: they break a threatening class of interaction into portions that can be survived. You do not resolve the whole conflict at midnight; you agree that neither of you leaves the house, and you take the rest tomorrow. That is the same principle applied to a fight instead of to a sensation. Both traditions inherited it rather than invented it — the finding that repeatedly approaching what is feared, in doses small enough to tolerate, reduces both fear and avoidance is one of the more consistently replicated results in the anxiety literature, and it belongs to neither of them.

What that makes the real goal

Say it without Levine's vocabulary and without Tatkin's, and the goal is to produce the kind of safety a body registers rather than the kind a sentence announces, and to produce it at a chosen time rather than whenever it happens to arrive. That is a strange-sounding target only until you notice how much of ordinary life it governs. It is what a good handover between shifts does, what a competent nurse does before a procedure, and what a parent does at a bedside. The target is not calm as a mood. It is the specific physiological event where a system that has been mobilised for something stands down, plus the ability to make that event happen on a Tuesday evening on purpose. Once the aim is stated that way, it belongs to no lineage, and the practices that serve it can be assessed on what they actually deliver.

Other practices that serve the same goal

Slow paced breathing with a longer exhale than inhale is the least glamorous route and carries some of the cleanest evidence: deliberately extending the out-breath for a few minutes measurably shifts markers of autonomic arousal, and the effect has been tested in randomised designs in ways most body practices have not. Progressive muscle relaxation — tensing and releasing muscle groups in sequence — is similarly old, similarly unfashionable and similarly well supported. Sensorimotor Psychotherapy, developed by Pat Ogden, works the same territory as Somatic Experiencing with a more explicit link to attachment relationships, which makes it a natural neighbour for couples work, though its evidence base is clinical rather than randomised. Stephen Porges's polyvagal framework is where much of the popular language about nervous-system states comes from, and it is worth knowing that its theoretical claims are contested among researchers even where the practices built on it are widely used — the framework's usefulness as a description does not settle whether its physiology is right. And there is a two-person route that neither practice on this page uses directly: synchronised breathing, where partners sit and match each other's breath for a few minutes. Laboratory work on couples has documented that partners' physiological states track each other, which is observational rather than experimental, but it is the most direct evidence that the setting for regulation is often another person rather than a technique.

A tradition that already does this

This move has already been made once, inside PACT itself. Tatkin did not build the model from communication theory; he built it from attachment work and from the study of how one person's arousal state moves another's, which is why its recommendations are so often physical — hold the hug longer, do the goodbye face to face, go to bed at the same time. The older ancestor both practices share sits in infant research, in Ed Tronick's still-face procedure, where a caregiver who has been interacting normally holds a blank, unresponsive expression for a short period. The infant escalates its bids for a response and then, when none comes, becomes distressed and turns away. What that procedure demonstrated is the premise underneath everything on this page: regulation is not only something that happens inside a nervous system, it is something that happens between two of them, and the withdrawal of a face is a physiological event and not merely a social one. Somatic Experiencing mostly works with one nervous system at a time and PACT works with two, but the finding they descend from is the same one.

Using Secure Functioning (PACT) to enhance Somatic Experiencing

Body-tracking is hard to do honestly next to someone who might react badly to what surfaces, and most people do not notice they are hedging — they simply track a slightly safer version, because some part of their attention is on their partner's face rather than on their own chest. PACT's contribution is to remove that job in advance, and it has a ready-made exercise for it. Tatkin's welcome home exercise is the one to use, and it is almost embarrassingly simple. One: when one of you comes in, stop what you are doing and greet each other with full body contact — a real hug, chest to chest, not the sideways version with a pat at the end. Two: lean weight into each other, so each of you is genuinely taking a little of the other's, because a hug where both people hold their own weight is a handshake with more surface area. Three: hold it until you feel the other person's body let go, and do not be the first to end it. That last instruction is the entire exercise. Most couples release at three or four seconds, which is roughly a second before anything happens. Four: agree in advance, in words, what happens if something surfaces during it — if one of you starts shaking, or tears show up without a story, or one of you needs to stop and sit down. Agree it will be met with staying rather than with questions, fixing, or a joke. That agreement is the safety that makes deeper tracking possible, and it has to be made before the moment, because in the moment it is exactly what nobody can negotiate. Five: expect the first several attempts to feel silly. Silly is not the same as failing; a system that has been braced for years does not stand down because you scheduled a hug, and the point is repetition rather than any single occasion. What this gives Somatic Experiencing is a setting. Without one, most people keep the brace and simply hold it more quietly, because part of them is still monitoring the room instead of the body.

Using Somatic Experiencing to enhance Secure Functioning (PACT)

A PACT ritual can be performed exactly as agreed and still fail to land, because a braced nervous system does not register a correctly executed ritual as safety. What the body offers here is a second channel of information, and pendulation is the technique to borrow — Somatic Experiencing's move of swinging attention deliberately between an activated place and a place that currently feels fine, rather than staring at the difficult sensation until it grows. Run it as a two-minute addition to a ritual you already have. One: each of you names one place in your body that feels neutral or good right now, in three words or fewer. Feet on the floor. Hands are warm. That is the anchor, and finding it first is not optional — going to the activated place without one is the most common way this goes badly. Two: each of you names the place that is holding something. Jaw. Stomach. Chest, tight. Three words again, no interpretation, no narrative about who caused it. Three: put attention on the difficult place for perhaps twenty seconds, then deliberately move it back to the neutral place for the same. Then again. Three or four swings, out loud or silently, and stop while it is still comfortable — the discipline is to stop early, because the point is teaching the system that it can go there and come back, not proving you can endure it. Four: each say one word about what changed, if anything. Often nothing changes, and nothing changing is normal. Five: notice the mismatches, because this is where the real value is for a couple. When your words say we're fine and your chest reports otherwise, that gap is the most useful information available to either of you, and a purely verbal check-in has no way to surface it. Two cautions. This is not therapy and it is not the place for either of you to open significant trauma; if something large arrives, the right move is to stop and get proper support, not to press on because the exercise had five steps. And do not use your partner's body report as evidence in an argument — the moment a tight stomach becomes proof that someone was lying about being fine, honest reporting ends for good.

The fight ended an hour ago and your shoulders have not been told

You made up before dinner. You both said real things, and you meant them, and the argument is over by every reasonable measure. Except your shoulders are somewhere near your ears, your breathing has been shallow for an hour, and you have just been shorter than you needed to be about the dishwasher. Instead of moving on to the next thing — which is what you would normally do, and which is how this ends up in Thursday — you stop in the kitchen and say the agreement out loud: we're okay, this isn't going anywhere tonight. Not as reassurance. As information for a part of you that does not read tone. Then you do the two minutes. You go first: feet on the floor is fine, and your shoulders are up. She says her hands are okay, her stomach is in a knot. You each move attention back and forth a few times, twenty seconds one way, twenty the other, nobody talking. Around the third swing your jaw does something you did not authorise and lets go, and you take one of those breaths that arrives on its own. She notices, because she is standing right there, and does not say anything about it, which is the correct move and the one you had agreed on. Her stomach takes longer and does not fully release, and she says so plainly, and that is not a failure of the exercise or of the evening — it is just where she is. What you have at the end is a body that came down in the same hour as the conversation, and a piece of information you would not otherwise have had: she was still holding something after you had stopped, which is worth knowing on a night neither of you is arguing.

When this is worth reaching for

The argument ended forty minutes ago by every measure you can name, and your body is still in it. That is the condition — a mismatch between what has been settled in words and what has been settled in you — and it is worth naming because most couples do not treat it as a thing that can be addressed. It just becomes the evening. A second condition: one or both of you goes quiet or flat under conflict rather than loud, so there is no visible signal to work with and the verbal check-in keeps returning fine. A third: the rituals are in place, they are being kept, and neither of you feels much from them, which usually means the words are landing somewhere the settling is not happening. And an explicit not yet — if either of you is in the middle of active trauma work, or if body attention reliably produces panic rather than information, this is not the month, and the sequence needs a clinician who can pace it rather than a page that can only describe it.

Where this does not apply

PACT's agreements address safety between two people and say little about how a nervous system processes stored survival stress on its own. Someone whose bracing predates the relationship — from earlier trauma that has nothing to do with this partner — may need somatic work that is not about the couple at all, and folding it into a shared ritual can quietly reframe an individual history as a relationship problem, which is both inaccurate and hard on the partner who did not cause it. In the other direction, Somatic Experiencing regulates one nervous system, or two working in parallel, and it does not by itself produce the structural agreements PACT exists to establish. A couple can get very good at settling their bodies together and still be operating from entirely different assumptions about money, family and what protecting the relationship means, and no amount of tracking will surface that; it takes an explicit negotiation. Two further limits. Body attention is not universally calming — for some people, particularly with a trauma history, turning attention inward increases distress rather than reducing it, and the practice then needs pacing by someone trained rather than a five-step list. And in a relationship where there is intimidation or a safety concern, an exercise that asks one partner to lower their guard in the other's presence is the wrong instruction, whatever the agreements say.

What the evidence does and does not support

Two different kinds of claim sit on the two sides of this page, and the difference matters more here than on most pairs. On the body side, directing sustained attention to internal sensation and having that change how a state is experienced carries randomised support, as does the broader finding that approaching what is feared in tolerable doses reduces fear and avoidance — that one is among the most replicated results in the anxiety-treatment literature. The specifically Somatic Experiencing claim, that physically completing a build-up-and-release cycle discharges stored tension rather than leaving it held, is graded clinical: it is a description of what practitioners repeatedly observe, and it is genuinely hard to isolate experimentally, because you cannot easily randomise a nervous system into finishing or not finishing an arc. Anyone telling you the discharge model is settled science is overstating it, and anyone dismissing the observations is ignoring a lot of consistent clinical report. On PACT's side, the attunement and explicit-commitment principles are clinical, and the claim about rituals is anecdotal. As for the two together: no study has tested a couple adding body-tracking to their agreements, and the design that would test it is straightforward enough to describe — randomise couples with existing rituals to add a two-minute pendulation step or not, and measure how long physiological arousal stays elevated after a conflict — which makes the absence a gap rather than an impossibility. What is offered above is a reading of two mechanisms that plausibly meet.
