Adaptation in Core Strokes®
How Living Organisation Changes While Perserving Viability
By Dirk Marivoet, Founder of Core Strokes®· Psychotherapist · Teacher · Author
Adaptation — Core Definition
Adaptation is the process through which living organisation changes in relation to the conditions in which it participates while preserving sufficient viability to continue.
Adaptation can occur over very different timescales.
Some adaptive changes are immediate and reversible. Movement changes when terrain becomes unstable. Attention narrows during a demanding task. Muscular effort increases when greater force is required.
Other adaptations become more enduring. Repeated environmental or relational conditions may contribute to stable patterns of posture, attention, emotional expression, behavioural expectation or interpersonal participation.
The important distinction is between Adaptation as an ongoing process and Adaptive Organisation as a relatively established configuration resulting from developmental or repeated adaptive processes.
Adaptation describes what living organisation does.
Adaptive Organisation describes how that history of adaptation may become relatively organised and enduring.
Adaptation Is Not the Same as Improvement
In ordinary language, adaptation can imply successful adjustment. Within living organisation, however, the situation is more complex.
An organism adapts to the conditions it encounters, not necessarily to ideal conditions.
If those conditions are supportive, adaptation may permit increasing exploration, Differentiation, Integration and participation.
If conditions are restrictive, unpredictable or threatening, adaptation may preserve viability by narrowing what can occur.
A child may inhibit particular forms of expression when they repeatedly disrupt an important relationship. A person may increase vigilance in an unpredictable environment. Movement may become guarded after repeated pain. Relational distance may become necessary when proximity repeatedly becomes overwhelming.
These adaptations may carry later costs while still having been organisationally meaningful under the conditions in which they developed.
Adaptation should therefore not be judged solely by whether the resulting pattern appears desirable in the present.
Its organisational significance depends partly upon the conditions to which it developed as a response.
Adaptation Is Not the Same as Regulation
Regulation and Adaptation are closely related, but they operate at different levels of the framework.
Regulation concerns the modulation of activity in relation to changing internal and external conditions.
Adaptation concerns how organisation itself changes through participation in those conditions.
A regulatory response may be brief. A person increases attention while crossing a busy street and relaxes afterwards. Muscular activity increases while lifting a heavy object and diminishes when the task is complete.
When particular regulatory configurations are repeatedly required, however, they may contribute to more enduring organisation.
Repeated vigilance can become habitual orientation. Repeated inhibition can shape expression. Repeated muscular protection can alter movement repertoire. Repeated relational withdrawal can become an established way of managing interpersonal intensity.
Regulation therefore concerns how activity is modulated now. Adaptation concerns how living organisation becomes shaped through its history of meeting conditions.
Adaptation and Continuity
Adaptation serves Continuity by allowing organisation to change rather than requiring it to remain identical.
When conditions alter, preserving exactly the same organisation may no longer be possible. Something must change if the organism is to continue participating.
Adaptation therefore represents one of the ways Continuity is maintained through transformation.
This is especially important under difficult conditions. A capacity may become restricted in one domain so that organisation can remain viable at another. Emotional expression may diminish to preserve relationship. Exploration may narrow to preserve safety. Movement may become guarded to avoid pain.
From this perspective, restriction does not necessarily represent the disappearance of organisation.
It may represent the means through which Continuity is being preserved.
Adaptation therefore reveals a central paradox of living organisation: change can be necessary in order for continuity to remain possible.
Adaptation and Pulsation
Pulsation concerns movement among changing states, directions and intensities. Adaptation concerns how the organisation of those possibilities becomes shaped through experience.
Repeated conditions may influence the range through which Pulsation occurs.
An organism repeatedly required to remain vigilant may develop a relatively narrow range around mobilisation. Another repeatedly required to inhibit expression may organise transitions towards containment before stronger activation becomes visible.
These patterns do not mean that Pulsation has disappeared.
Rather, the organisation of Pulsation has adapted.
Certain transitions may become easier, others less available. Some intensities may be rapidly amplified, while others are curtailed. Particular directions of movement may become recurrent because they have repeatedly contributed to viability.
Adaptation therefore influences the repertoire through which Pulsation can unfold.
Adaptation and Propagation
Adaptation also shapes how change becomes consequential across living organisation.
Repeated experience can influence whether local activation remains local, spreads widely, becomes amplified or is rapidly contained.
A relatively small relational cue may produce widespread changes in attention, breathing and muscular organisation when similar cues have repeatedly been associated with difficulty. Conversely, strong experience may remain highly localised when broader propagation has previously been costly.
Such patterns can become part of Adaptive Organisation.
Propagation therefore describes how influence extends across organisation, while Adaptation concerns how the organisation of those relationships becomes shaped through repeated participation.
What propagates, how far it propagates and what constrains its propagation can all acquire adaptive organisation over time.
Adaptation and Differentiation
Adaptation can preserve, expand or restrict Differentiation.
Supportive conditions may permit increasingly precise distinctions among sensations, emotions, impulses, movements, relationships and environmental possibilities.
Under other conditions, maintaining such distinctions may become difficult or unnecessary. Organisation may become more global, or certain distinctions may receive disproportionate priority.
A person exposed to recurrent interpersonal uncertainty, for example, may become exceptionally sensitive to subtle changes in another person’s expression while remaining less differentiated in relation to their own bodily or emotional experience.
This should not simply be described as greater or lesser Differentiation.
Adaptation can redistribute Differentiation according to what has become organisationally relevant.
Some distinctions become highly refined because they support viability. Others remain less available because they were less useful, more costly or insufficiently supported under previous conditions.
The resulting organisation may therefore contain both remarkable capacities and significant restrictions.
Adaptation and Integration
Adaptation also changes which differentiated processes can participate together.
Under supportive conditions, a wide range of sensations, emotions, impulses, thoughts, movements and relational information may remain available within larger patterns of Integration.
Under difficult conditions, Integration may become more selective.
Some processes may need to be excluded, inhibited or compartmentalised so that other aspects of organisation can continue functioning. Emotional awareness may become separated from action. Bodily sensation may receive reduced attention during sustained demand. Relational engagement may remain possible only when certain impulses are contained.
These organisations may later appear fragmented or restricted, but their adaptive history matters.
Integration has not necessarily failed. Rather, a particular form of Integration may have developed around what could remain organisationally viable under those conditions.
Therapeutic work can therefore explore not only what appears insufficiently integrated, but what existing organisation has been preserving through that configuration.
Adaptation and Self-Organisation
Adaptive patterns frequently emerge through Self-Organisation.
No central controller needs to decide that vigilance should become habitual, that a particular movement should be avoided or that emotional expression should become constrained.
Patterns can gradually emerge through repeated interactions among bodily processes, environmental conditions, relational experience and previous organisation.
Once established, these patterns become part of the conditions from which subsequent Self-Organisation occurs.
Adaptation is therefore recursive.
Previous adaptations influence how new situations are perceived and encountered. Those responses generate further experience, which may reinforce, modify or reorganise established patterns.
This helps explain why enduring organisation can remain stable even after external circumstances change.
The organisation does not simply respond to the present environment. It encounters present conditions through patterns shaped by its previous participation.
Adaptation and Regulation
Regulation provides many of the moment-to-moment processes through which Adaptation develops.
Repeated modulation can gradually become characteristic organisation.
A person who repeatedly needs to reduce emotional activation in order to remain connected may become highly skilled at doing so. Someone who repeatedly needs rapid mobilisation may develop a regulatory organisation that recruits activation quickly. A person living with recurring uncertainty may sustain heightened orientation towards environmental change.
Over time, these regulatory patterns can become increasingly stable.
Adaptation therefore does not replace Regulation. It concerns how regulatory histories contribute to the organisation through which subsequent conditions are encountered.
At the same time, Adaptive Organisation shapes future Regulation by influencing which regulatory responses become readily available.
The relationship is reciprocal: Regulation contributes to Adaptation, and established adaptation constrains and enables subsequent Regulation.
Adaptation and Participation
Adaptation cannot be understood independently of Participation.
Living organisms adapt in relation to conditions.
These conditions include physical environment, developmental circumstances, relationships, culture, social structures, bodily capacities and the consequences of previous activity.
Adaptation is therefore not something that occurs exclusively inside the individual.
A relational pattern, for example, develops through repeated participation with others. Behaviour that appears avoidant in one context may have emerged because distance was repeatedly necessary within another. Strong interpersonal monitoring may have developed because subtle relational changes previously carried important consequences.
Understanding adaptation therefore requires attention to the field in which organisation developed.
This does not mean that current behaviour can be explained entirely by past conditions. Present organisation is always occurring now.
It means that its present configuration may carry the history of how participation became organised under previous conditions.
Adaptation and Coherence
Adaptation also clarifies an important feature of Coherence.
A pattern can be coherent without being optimal.
Processes may become meaningfully coordinated around protection, inhibition, vigilance or withdrawal. The resulting organisation can possess substantial internal consistency precisely because multiple processes have adapted together.
Breathing, posture, attention, emotional expectation and relational behaviour may all participate within the same adaptive configuration.
This is one reason why established patterns can be difficult to change.
They are not merely isolated symptoms waiting to be removed. They may belong to a wider organisation whose elements mutually support one another.
Therapeutic change therefore requires sensitivity to the coherence of adaptation rather than assuming that apparently problematic elements can simply be corrected independently.
Adaptive Organisation
Adaptive Organisation refers to relatively enduring configurations through which previous adaptation has become organised across embodied, experiential and relational life.
An Adaptive Organisation may include characteristic relationships among posture, breathing, movement, attention, affect, expectation and participation. These relationships need not be fixed, nor do they define the whole person.
They represent recurring organisational tendencies that have acquired relative stability.
Adaptive Organisation should therefore not be understood as a diagnostic category or permanent personality type.
It describes how living capacities can become organised through developmental and experiential history.
Importantly, Adaptive Organisation preserves capacities as well as constraining them.
The question is not simply what has been lost.
It is also what remains possible, what has been preserved, and how those preserved capacities continue to support viability within the organisation that developed.
Defensive Organisation
Defensive Organisation refers to organisation in which protective functions have become particularly significant in preserving viability under conditions experienced as difficult, threatening, overwhelming or incompatible with broader participation.
Defensive Organisation is therefore not the opposite of living organisation.
It is living organisation configured around protection.
Muscular holding, withdrawal, vigilance, emotional inhibition, behavioural control, reduced movement, increased activation or restricted relational participation may all contribute to such organisation under particular conditions.
These patterns can carry substantial costs. They may reduce flexibility, limit experience or maintain responses that are no longer required by present circumstances.
Yet describing them only as dysfunction obscures their organisational significance.
A defensive pattern may be preserving Continuity, maintaining Coherence, regulating intensity, limiting Propagation or protecting capacities that could not remain viable in another form.
The therapeutic question therefore becomes more precise:
What is this organisation protecting, preserving or making possible, and under what conditions did that organisation become necessary?
Adaptive Organisation and Defensive Organisation
Adaptive Organisation and Defensive Organisation overlap, but they should not be treated as synonyms.
All Defensive Organisation is adaptive in the broad sense that it emerges in relation to conditions and preserves some form of viability.
Not all Adaptive Organisation, however, needs to be predominantly defensive.
Adaptation also includes developmental learning, increasing skill, changing movement organisation, relational maturation, accommodation to bodily change and the expansion of capacities under supportive conditions.
The term Adaptive Organisation therefore identifies the broader category of relatively enduring organisation shaped through adaptation.
Defensive Organisation identifies adaptive configurations in which protection, restriction or limitation has become especially important to maintaining viability.
This distinction prevents two opposite errors.
The first is treating adaptation as inherently healthy.
The second is treating adaptive restriction as inherently pathological.
Core Strokes® instead asks how organisation developed, what it preserves, what it restricts and whether its present configuration remains responsive to current conditions.
The Adaptive Continuum
The Adaptive Continuum extends this inquiry by examining progressively restricted forms of adaptive organisation.
Within the Fascia Texture Typology™, recurring tactile configurations such as Gritty, Sandpaper, Mud, Cold Wax and Wilted Leaf became phenomenological doorways into different adaptive organisations.
The significance of these textures does not lie in treating tactile qualities as diagnoses or as direct representations of psychological history.
They provide phenomenological observations through which deeper questions concerning organisation can be investigated.
The developing constitutional reconstruction of the Adaptive Continuum therefore asks not simply which texture is perceived, but which organisational capacities remain preserved as adaptation becomes increasingly restrictive.
This changes the meaning of the continuum.
It is not primarily a scale from health to pathology.
It investigates how living organisation can remain viable through progressively restricted configurations and which capacities must remain preserved for each organisation to remain possible.
The tactile phenomenon is therefore an observational entry point, not the constitutional explanation itself.
Adaptation and the Body
Adaptive history becomes perceptible through the body, although bodily patterns should not be treated as direct records of particular past events.
Movement repertoire can change after injury. Posture can reorganise under repeated physical demand. Breathing patterns can become associated with recurring forms of activity. Muscular recruitment can become increasingly characteristic when certain actions are repeatedly required.
Relational and emotional histories may likewise participate in embodied organisation, but no bodily configuration allows a practitioner to read a specific developmental history directly from the body.
Core Strokes® therefore distinguishes carefully between observation and interpretation.
The practitioner may observe recurring patterns of posture, movement, breathing, effort, orientation or response.
These observations can contribute to hypotheses about Adaptive Organisation only when considered in relation to wider embodied, experiential and relational information.
The body expresses organisation in the present. It does not function as a literal archive that can simply be decoded.
Breath and Adaptation
Breathing participates continuously in adaptation because respiratory organisation changes with activity, physiology, posture, emotion and environmental conditions.
Repeated conditions can contribute to characteristic respiratory patterns.
A person may habitually restrict respiratory movement during demanding interactions, recruit stronger breathing during mobilisation or maintain particular relationships between breath and muscular activity.
Such patterns can become clinically meaningful when they recur across situations.
They should not, however, be assigned fixed psychological meanings.
A restricted breath does not by itself demonstrate fear, trauma or inhibition. A fuller breath does not automatically indicate health or emotional freedom.
Within Core Strokes®, breathing becomes informative through relationships: how it changes with movement, expression, relational conditions and other aspects of organisation.
Adaptive significance is inferred from recurring patterns across contexts rather than read directly from respiratory form.
Fascia and Adaptation
Fascia and connective tissues participate in the mechanical history of embodied life.
Loading, movement, injury, immobilisation, physical activity and repeated patterns of muscular recruitment can influence tissue organisation and mechanical relationships.
Therapeutic palpation may also disclose recurring tactile qualities.
Within the Fascia Texture Typology™, such qualities are described phenomenologically before wider organisational interpretation is considered.
This distinction is essential.
A tactile texture does not contain a psychological adaptation, developmental history or memory. Nor does it establish a causal explanation for the organisation with which it is associated.
Instead, recurring tactile configurations can provide one perceptual window into wider embodied organisation.
The Adaptive Continuum emerged through this phenomenological doorway, but its developing constitutional significance lies increasingly in the organisational capacities disclosed through those observations rather than in the textures themselves.
Emotional Adaptation
Emotional life also adapts.
Certain emotions may become readily accessible because they support effective participation under recurring conditions. Others may become difficult to sustain, express or distinguish.
A person may become highly capable of mobilising anger while vulnerability remains less available. Another may readily perceive sadness but inhibit anger. Someone else may become exceptionally sensitive to the emotional states of others while remaining less differentiated in relation to their own experience.
These organisations should not automatically be understood as emotional deficits.
They may reflect histories in which particular emotional configurations supported relationship, protection, belonging or effective action.
Therapeutic work can investigate whether the existing emotional repertoire remains adequate for present conditions and whether additional possibilities can emerge without requiring the person to abandon capacities that remain valuable.
Adaptation and Relationship
Many human adaptations develop within relationship.
Children depend upon relationships for survival and development. Adults continue to participate within intimate, familial, professional, social and cultural environments that shape possibilities for action and expression.
Relational adaptation may therefore involve changing how proximity, expression, boundaries, dependency, autonomy, reciprocity or conflict are organised.
A person may learn to monitor others closely, minimise demands, become highly self-reliant, maintain harmony, increase control, avoid confrontation or rapidly accommodate to another person’s needs.
Such patterns may later appear limiting, yet they can carry considerable relational intelligence.
Understanding them requires asking what relational conditions they developed within and what they enabled the person to preserve.
Therapeutic relationship can then provide conditions in which established adaptations become perceptible and alternative forms of participation can gradually be explored.
Adaptation and Relational Geometry
Relational Geometry provides a concrete way of observing aspects of adaptive organisation.
Characteristic patterns may appear in proximity, distance, orientation, boundary, direction, reciprocity, approach and withdrawal.
One person may consistently increase distance as emotional intensity rises. Another may move closer when uncertainty develops. Someone may orient strongly towards another person’s responses while reducing attention to their own position.
These patterns do not possess fixed meanings.
The same geometry can serve different functions in different people or situations.
Its value lies in making recurring organisation observable.
When relational geometry is considered together with breathing, movement, affect, reported experience and the changing conditions of interaction, it can contribute to hypotheses about how relational adaptation has become organised.
Trauma and Adaptation
Trauma provides an especially important context for understanding Adaptation.
Under overwhelming conditions, living organisation may need to reorganise rapidly around survival and protection.
Attention can narrow. Mobilisation may intensify. Movement may become inhibited. Emotional experience may change. Relational participation can become organised around vigilance, withdrawal, appeasement, control or other protective responses.
These changes are not necessarily failures of organisation.
They can represent adaptive solutions under extreme conditions.
Difficulties may emerge when organisation shaped under those conditions remains strongly recruited in circumstances where broader possibilities have become available.
The person is then not simply “stuck in the past.” Present organisation is actively occurring, but its repertoire has been shaped by previous conditions.
Therapeutic work can therefore focus less on eliminating trauma responses and more on understanding what they preserve while creating conditions in which additional organisation becomes possible.
Adaptation and Development
Development is inseparable from Adaptation because development always occurs under particular conditions.
The developing organism does not unfold independently of environment and relationship. Capacities emerge through participation with bodily, material, relational, cultural and social worlds.
Development therefore includes both increasing capacities and the organisation of those capacities in relation to actual circumstances.
Some developmental conditions support broad exploration and Differentiation. Others require particular capacities to be prioritised, restricted or reorganised.
This means that development cannot be understood solely by comparing an individual with an ideal developmental sequence.
The organisational question is also historical:
How did this living organisation become viable within the conditions through which it developed?
This perspective does not deny developmental difficulty. It allows difficulty to be investigated without losing sight of the adaptive intelligence contained within the organisation that emerged.
The Developmental Organisation of Adaptation
Adaptation does not appear at a particular developmental stage. It is present throughout life.
What develops is the complexity of the organisation available for adaptation.
Early adaptation depends strongly upon bodily and relational conditions. As movement, communication, Differentiation and Integration develop, the organism acquires additional possibilities for changing its relationship with the environment.
Later development introduces increasingly complex relational, social, symbolic and cultural conditions.
Each new capacity expands possible adaptation while previous adaptations continue to shape how those possibilities are encountered.
Development therefore accumulates history.
New organisation does not simply replace old organisation. Earlier adaptive patterns may remain available, become integrated within more complex configurations, or become strongly recruited again under particular conditions.
Maturity should therefore not be equated with freedom from adaptation.
A mature living organism remains adaptive.
What may broaden is the repertoire through which adaptation can occur without unnecessarily sacrificing capacities that remain viable under present conditions.
Adaptation Across Changing Conditions
One of the most clinically important questions is whether an adaptation remains responsive when conditions change.
An adaptive pattern may be highly appropriate in one environment and unnecessarily restrictive in another.
Vigilance may be essential under danger but costly in sustained safety. Emotional inhibition may preserve functioning during crisis but constrain intimacy when the crisis has passed. Strong self-reliance may support survival under unreliable conditions while later limiting the capacity to receive support.
This does not mean that the earlier adaptation has become meaningless.
Its history remains part of the organisation.
Therapeutic transformation involves the possibility that present conditions can increasingly participate in how organisation is shaped.
The question becomes whether living organisation can recognise, tolerate and respond to differences between previous and current conditions.
Observing Adaptation
Adaptation cannot be directly perceived as an abstract principle.
What becomes observable are recurring relationships among activity, conditions and changes over time.
Observation may include:
- which responses recur under particular conditions;
- how posture and movement change with environmental or relational demand;
- which forms of activation are readily available and which are rapidly inhibited;
- how breathing changes across different situations;
- what happens when familiar relational patterns are interrupted;
- which distinctions remain available under increasing intensity;
- how boundaries, proximity and orientation change within relationship;
- which capacities remain available when organisation becomes more constrained;
- whether organisation changes when present conditions differ from previous expectations;
- how rapidly established patterns return after temporary change.
No single observation establishes an adaptation or reveals its developmental origin.
A repeated pattern may support an adaptive hypothesis, but interpretation requires attention to context, history, recurrence and relationships among multiple observations.
Within Core Strokes®, phenomenological description therefore precedes organisational interpretation.
The Living Participation Observation System™ (LPOS™) provides a structured phenomenological framework for describing such changes before provisional organisational interpretations are developed.
Adaptation and Therapeutic Touch
Therapeutic touch encounters organisation that already has a history.
Tissue responsiveness, muscular activity, breathing, movement and the participant’s responses to proximity and contact may all display recurring patterns.
The practitioner should not assume that resistance is an obstacle to be overcome or that yielding necessarily represents improvement.
A resistant response may preserve boundary, stability or protection. A yielding response may expand possibilities, but under some circumstances it may also reflect reduced organisation or excessive accommodation.
The meaning cannot be determined from the tactile quality alone.
Therapeutic touch therefore requires attention to what changes across the wider organisation.
Does breathing change? Does movement become more or less available? Does the participant become clearer about sensation or boundary? Does contact increase or reduce relational participation? Does a local change remain stable when the context changes?
Touch becomes a way of participating with Adaptive Organisation rather than an attempt to erase adaptation from the body.
Adaptation and Therapeutic Transformation
From the perspective of Adaptation, therapeutic transformation is not the replacement of an adapted organism with an unadapted one.
There is no unadapted human organisation to recover.
Living organisation develops through adaptation from the beginning of life.
Therapeutic change therefore concerns whether established adaptations remain necessary in their current form and whether additional organisational possibilities can become viable under present conditions.
This may involve greater Differentiation, new forms of Integration, altered Regulation, broader Pulsation, different relational participation or changes in how activity propagates across organisation.
Such changes cannot simply be imposed.
Existing adaptations may be preserving capacities that would be destabilised if the pattern were removed too rapidly.
Therapeutic work therefore requires respect for the intelligence of established organisation while remaining open to its possible reorganisation.
The practitioner participates in conditions through which the person can encounter what the existing adaptation accomplishes, recognise its costs and explore whether broader possibilities can become sustainable.
Transformation does not invalidate adaptation.
It allows adaptation itself to continue.

Final Orientation
Within Core Strokes®, Adaptation describes how living organisation changes in relation to the conditions through which life is lived.
Adaptation is neither inherently healthy nor inherently pathological.
It may expand possibilities, but it may also preserve viability through restriction. Capacities can be maintained, reorganised, prioritised or constrained according to what particular conditions make possible.
This perspective changes how enduring difficulties are understood.
A restrictive pattern is not necessarily evidence that organisation has failed. It may reveal how organisation succeeded in preserving something essential under circumstances in which broader possibilities could not be sustained.
The therapeutic task is therefore not simply to remove the adaptation.
It is to understand what the adaptation preserves, what it restricts, whether the conditions that required it remain present, and whether additional possibilities can become viable now.
Adaptation is the continuing reorganisation of living possibility in relation to the conditions of life.
