The Principle of Dominance holds that, in any given moment, attention is organized around a single dominant dimension of functioning. This principle mirrors the organization of the nervous system, where conscious awareness can sustain only one coherent representation at a time, never multiple or contradictory ones (Mashour et al., 2020).

Of course, the psyche is always distributed across all dimensions. Even now, as you read these lines, your mind is simultaneously active in several domains: in action (the physical act of reading), in thought (grasping the author’s intent), in emotion (feeling something toward the text or its author), in experience (sensing an inner state- perhaps curiosity, irritation, or absorption), and in being (inhabiting your enduring professional identity as a clinician or scholar). Yet focused awareness can occupy only one dimension at a time.

Much like Rubin’s famous vase illusion, where one perceives either two faces or a vase, but never both simultaneously, consciousness alternates between possible configurations.

We cannot hold two incompatible Gestalts at once, just as we cannot be fully present in more than one psychological dimension in the same moment.

The Principle of Dominance is evident both in everyday mental life and in psychotherapy. Activating a cognitive operation, such as performing repeated subtraction (e.g., 100-7-7…), can redirect attention away from an affective state of anger. This mechanism underlies many anger-management interventions, which train participants to shift from emotion to other dimensions, typically thought (e.g., spelling a long word backward) or action (e.g., performing a repetitive physical task such as tossing a yo-yo) (Denson et al., 2012; Kjærvik and Bushman, 2024). Such redirection rests on the Principle of Dominance: by mobilizing another mode of functioning, the psyche reorganizes itself, thereby reducing the dominance of the emotional state.

The Principle of Continuity states that transitions within the psyche occur between adjacent dimensions, unfolding sequentially rather than through abrupt leaps. Movement along the dimensional cascade, from being to experience, from experience to emotion, from emotion to thought, from thought to action, or in reverse, proceeds in sequence, without skipping a level. In other words, the psyche evolves through successive transitions in which each mode of functioning arises from the one before it and conditions the emergence of the next. Mental life progresses through transitions that mediate and integrate what precedes with what follows.

For example, when moving from emotion (“What do I feel toward the other?”) to action (“What do I do with the other?”), the transition necessarily passes through thought (“What meaning or decision arises from my feeling, and what action does it entail?”).

Likewise, when moving in the opposite direction, from action (“What did I do with the other?”) to emotion (“What do I feel about it?”), the shift unfolds through thought (“What do I think about what I did, and what feeling follows from that thought?”).

This principle rests on a developmental and phenomenological premise shared across major psychological traditions: transformations within the psyche unfold through neighboring modes of functioning rather than through abrupt leaps. In psychodynamic theory, the Principle of Continuity can be traced from Freud’s (1894) notion of affect transformation to Bion’s (1962) description of converting beta elements into alpha elements, both depicting a sequential, metabolizing process rather than a discontinuous shift (Riolo, 2007). Developmental and cognitive models, from Piaget’s stages (Quartz, 1999) to Edelman’s Neural Darwinism (Seth and Baars, 2005) likewise conceive psychological organization as a graded coordination of perceptual, emotional, and conceptual systems. In phenomenology, Merleau-Ponty’s (2012) “continuous intentional arc” (1945) and Heidegger’s account of Dasein as temporal unfolding both affirm that being, feeling, and acting are contiguous expressions of a single coherent movement of mind (Heidegger, 1962).

Everyday decision-making illustrates the Principle of Continuity with particular clarity.

When an individual acts deliberately, the psyche rarely leaps between states; rather, it traverses a sequence of adjacent transitions (experiencing, feeling, thinking, and acting), each shaping the next. Contemporary research on decision-making supports this conception. Neurocognitive models such as Damasio, 1996 Somatic Marker Hypothesis suggest that adaptive choice depends on a graded integration of bodily, emotional, and cognitive signals rather than on discrete computation. Dual-process theories (Kahneman, 2011; Evans, 2008) likewise describe reasoning as a continuous interaction between intuitive and reflective systems. Taken together, these findings suggest that coherence arises from the psyche’s capacity to transform experience into emotion, emotion into thought, and thought into intentional action.

This sequential description should be understood as the typical architecture of psychological transformation rather than as an invariant rule. Clinical change may at times appear to involve non-adjacent shifts; however, such moments often reflect rapid integrations in which intermediate processes remain phenomenologically implicit rather than structurally absent. The principle of continuity therefore describes the psyche’s underlying organization even when experiential change appears sudden.

In clinical work, the Principle of Continuity is vividly expressed through the operation of defense mechanisms, which disrupt the psyche’s integrative movement linking affect, thought, and symbolization. As Fonagy and Target (1996) observe, defensive exclusion entails “a breakdown in the continuity of mental experience,” interrupting this integrative process and fragmenting the links that connect emotion, cognition, and meaning. In acting out, the individual moves directly from experience to action, bypassing emotion and thought, so that the feeling is enacted rather than symbolized. In intellectualization, movement halts within thought, severed from its emotional and experiential ground. In repression, the passage is blocked even earlier, preventing experience from transforming into emotion. Each defense thus represents a failure of transition between adjacent dimensions. Therapeutically, restoring these links (e.g., enabling emotion to emerge from experience, or thought from emotion) re-establishes the psyche’s natural continuity and allows meaning, rather than impulse, to govern action.

The Principle of Equilibrium holds that the psyche continuously regulates the balance among its dimensions, adapting to both internal and external demands. Psychological equilibrium is never static; it is inherently contextual and shifting. At any given moment, the psyche maintains a dynamic balance among its five dimensions, action, thought, emotion, experience, and being, which reorganizes in response to situational pressures or inner tensions. In a therapeutic encounter, for instance, a discussion about medication decisions may evoke a configuration dominated by thought, where analytical reasoning prevails; yet when the dialogue turns to the emotional meaning of a diagnosis, the equilibrium often shifts toward deeper emotional and experiential layers, where feelings are not only expressed but inwardly lived, and the therapist’s attunement helps sustain the emerging experience.

Stimulation that provokes inter-dimensional transitions may originate externally or internally, from another person, an evocative event, or an emergent impulse within the psyche itself. Gentle or transient stimulations induce soft, reversible transitions that momentarily reshape dimensional balance before returning to a habitual state. Intense or prolonged stimulations, such as traumatic or life-altering experiences, may produce deeper transitions that disrupt and reorganize the psyche’s equilibrium, often leading to a new configuration that may be either adaptive or maladaptive, yet bears the enduring imprint of transformation.

The Principle of Equilibrium is evident both in everyday life and in psychotherapy. In daily experience, it manifests as the subtle yet constant regulation of balance among the dimensions. This dynamic is especially visible in infancy. As Stern (1985) described, the minute exchange of signals between infant and caregiver generates micro-movements within the psyche, tiny oscillations between experience and emotion that sustain vitality, regulation, and connection. Crucially, Stern’s observations show that changes in psychological equilibrium must occur on a moment-to-moment basis and with exquisite delicacy: when transitions are too abrupt or intense, regulation collapses; when they remain finely tuned and responsive, integration deepens. The psyche, like the dyadic field between infant and mother, reorganizes not through force but through sensitivity (i.e.,- through the smallest possible perturbations that preserve coherence while enabling transformation).

In psychotherapy, the same principle operates through interpersonal resonance.

The therapist’s intervention, whether interpretive, empathic, or experiential, acts as a stimulus that gently perturbs the system of dimensional relations, momentarily shifting the patient’s habitual equilibrium. A reflective interpretation may reorient balance toward thought, while an empathic attunement invites emotion or experience to re-emerge. When the intensity of the stimulus exceeds the patient’s capacity for regulation, however, equilibrium may collapse, resulting in a therapeutic rupture rather than integration (e.g., Eubanks et al., 2018). When therapeutic contact provides sufficient stability and containment, these micro-perturbations instead accumulate over time into deeper reorganization, allowing the psyche to establish a renewed equilibrium in which previously dissociated dimensions can coexist in greater harmony (see, for example, Kernberg et al., 2012).

The fourth principle governing the relations among dimensions is the Principle of Mutual Attraction: when two individuals meet, each tends, often unconsciously, to draw the other toward the equilibrium of their own dimensional state. Put simply, when two people occupy different dimensional states and encounter one another, each tends to draw the other toward their own dominant dimension.

The Principle of Mutual Attraction operates across all dimensions. When someone attacks us (action), we instinctively defend ourselves physically (action); when a friend poses a riddle (thought), we are drawn into reasoning (thought); When a partner says “I love you” (emotion), it evokes a feeling in us (emotion); when another person turns inward and dwells in their inner world (experience), our attention often follows inward (experience); and when we encounter someone whose being radiates calm and groundedness, our own sense of being tends to harmonize with theirs.

In everyday life, the Principle of Mutual Attraction is principle quietly operates whenever emotional or mental states synchronize between people. A calm interlocutor can gradually slow the speech, breathing, and thought of an anxious partner; an agitated atmosphere in a group can quickly mobilize action or defensiveness among its members. These are not instances of content being “passed” from one person to another, but of equilibrium being co-regulated, as each person’s dimensional configuration subtly re-tunes itself in relation to the other’s.

In psychotherapy, the Principle of Mutual Attraction can be understood as a dynamic of reciprocal regulation that underlies all relational processes. Conceptually, it resonates with the psychoanalytic notion of projective identification as a bidirectional communicative process (Ogden, 1982), and with later intersubjective and relational theories that view the therapeutic dyad as a system of mutual influence (Stolorow et al., 1994; Mitchell, 2000). Empirically, similar dynamics have been described in research on affective attunement and mutual regulation (Stern, 1985; Tronick, 1989), as well as in neuropsychological studies of mirror systems and empathic resonance (Gallese, 2003). Across these perspectives, therapeutic interaction is understood not as a unidirectional intervention but as a co-regulated field, in which each participant’s dimensional configuration continuously adjusts in response to the other’s. Within the framework of the dimensional model, this corresponds to a constant modulation of balance among action, thought, emotion, experience, and being, through which shared meaning and transformation emerge.

The fifth principle, the Principle of Flexibility, holds that the capacity to move freely between dimensions constitutes both a sign and a mechanism of psychological adaptability. Throughout the psychoanalytic tradition, mental health has been associated with the ability to shift fluidly among different modes of psychic organization. For Freud (1900), this was reflected in the free mobility of psychic energy; for Bion (1962), in the mind’s capacity to oscillate between modes of thought; for Winnicott (1971), in the spontaneity that allows play between inner and outer reality; and for Bromberg (1998), in the flexible movement among self-states that transforms dissociation into integration. Within the Dimensional Model, the Principle of Flexibility extends this long-standing idea: the greater the fluidity of movement across the five dimensions, the greater the individual’s adaptability, coherence, and psychological well-being.

Table 2 presents the five principles of dimensional dynamics.

The dimensional model provides a clinically accessible method for analyzing and refining psychotherapeutic work. By translating complex psychodynamic principles into a concise and structured model, it allows therapists to observe the unfolding of therapeutic dialogue in terms of transitions between five psychological dimensions. Each utterance in the clinical exchange can be viewed as representing one dominant dimension, and the progression of these utterances reflects the movement of the therapeutic process itself.

This approach enables the therapist to identify how the dialogue evolves, whether it progresses smoothly through adjacent dimensions or exhibits abrupt transitions that may indicate defensive maneuvers, ruptures, or missed opportunities for attunement. The framework is guided by the five governing principles [dominance (which states that only one dimension is active at a time); continuity (which posits that movement occurs between adjacent dimensions); equilibrium (which describes the dynamic balance among them); mutual attraction (which captures the intersubjective pull between therapist and patient); and flexibility (which reflects psychological adaptability and health)].

By mapping clinical material through these principles, therapists can gain a clearer view of the structure and rhythm of their interventions. Breaks in continuity or dominance, for example, can signal moments where the therapist’s focus diverged from the patient’s experiential position. Conversely, alignment across dimensions can reflect depth, resonance, and therapeutic growth. The model thus provides a precise language for describing therapeutic processes, enabling the therapist to reflect not only on what was said, but on how each intervention positioned itself within the unfolding psychological process.

In clinical supervision and training, the dimensional perspective offers more than a practical framework. It establishes a shared conceptual language for articulating the complexity of therapeutic encounters. By mapping the shifting configurations of action, thought, emotion, experience, and being within the session, it grounds reflective dialogue in a coherent systemic logic. This coherence bridges theory and technique, enabling supervision to move beyond procedural correction toward an exploration of the evolving psychological field itself. In this way, the dimensional model transforms psychodynamic understanding into a structured yet flexible method of reflective inquiry, one that is teachable, replicable, and anchored in lived clinical phenomena. It thus provides a fertile basis for implementing deliberate practice (Hilsenroth and Diener, 2017; Rousmaniere et al., 2017) in psychotherapeutic practice and supervision (Mendlovic, 2025) supervision, responding to recent calls for frameworks that operationalize reflection and growth within the everyday ecology of supervision (Berning et al., 2024; Clements-Hickman and Reese, 2020).

The following four clinical vignettes illustrate how the operational principles of the Dimensional Model can guide moment-to-moment understanding in psychotherapy. All clinical vignettes are fictional and constructed solely for illustrative purposes. They are not drawn from, nor do they quote, any real clinical case or therapeutic session. Accordingly, no patient data or identifying details are included. Each vignette presents a brief segment of patient discourse, followed by two therapist responses (Therapist 1 and Therapist 2). The first response exemplifies alignment with the principle under discussion, while the second deliberately departs from it. Together, these contrasting interventions demonstrate how adherence to- or deviation from- the relevant dimensional principle shapes the session’s depth, continuity, and vitality.

For the sake of illustrative simplicity, all examples focus on the dimension of experience, which provides a common ground for demonstrating the model’s clinical logic.

Systematic coding of therapeutic dialogue has become a cornerstone of psychotherapy research, enabling fine-grained examination of therapeutic processes and mechanisms of change (e.g., Pereira et al., 2025). The MATRIX (Mendlovic et al., 2017) exemplifies such a framework: a theory-based and empirically validated tool designed to map the phenomena occurring within the therapeutic encounter. It is structured along two intersecting axes, the focus of observation (patient, therapist, dyad) and the dimension of inquiry (potential, content, relation), yielding nine possible configurations that together capture the dynamics of clinical dialogue.

Across several studies, the MATRIX has demonstrated strong reliability and predictive validity. Synchrony between patient and therapist codes was shown to distinguish successful treatments, with increasing convergence over time associated with positive outcomes (Mendlovic et al., 2019). Subsequent analyses revealed that congruence within the potential dimension accounted for most of the variance in treatment results (Bar et al., 2021), underscoring its theoretical and clinical significance. More recent work extended the MATRIX to quantify discursive richness and to identify ineffective “out-of-matrix” interventions, both yielding predictions of alliance and symptom change (Bar et al., 2023, 2025). Together, these findings illustrate how dimensional coding can advance the empirical study of psychotherapy by operationalizing the transitions and balances that define its inner logic.

The MATRIX is one example among a range of systematic process-research tools in which psychotherapy sessions are transcribed, coded, and analyzed according to defined theoretical models. These frameworks have sought to operationalize the moment-to-moment unfolding of treatment. Such are the Core Conflictual Relationship Theme (CCRT), which maps recurring relational patterns of wish–response of other–response of self; the Structural Analysis of Social Behavior (SASB), which codes interpersonal exchanges along axes of love, control, and autonomy; the Assimilation of Problematic Experience Scale (APES) and the Experiencing Scale, which quantify levels of emotional processing; and systems such as the Psychotherapy Process Q-Sort, Narrative Process Coding, and Rupture-and-Repair analyses, each highlighting different facets of therapeutic interaction (for extensive review, see Luo and Levendosky, 2025).

Like these instruments, the Dimensional Model seeks to describe the underlying organizational structure of mental processes. However, it extends beyond the analysis of therapeutic discourse, offering a parsimonious and broadly applicable framework for conceptualizing psychological functioning. Its advantages lie in its clarity, integrative potential, and ease of use: the model captures the complexity of mental life through five nested and hierarchically related dimensions (action, thought, emotion, experience, and being) which can be applied consistently across clinical, research, and theoretical contexts.

The following propositions illustrate how the model’s principles can be translated into falsifiable research hypotheses. To translate the Dimensional Model from conceptual framework to testable system, future studies should operationalize its principles as measurable process variables. Several hypotheses are directly derivable from the model. For instance, violations of the Principle of Continuity (abrupt transitions skipping adjacent dimensions) may predict therapeutic ruptures or defensive enactments, while greater dimensional flexibility, quantified as the range and fluidity of transitions within sessions, should correlate with better therapeutic outcomes. Similarly, alignment between patient and therapist dominant dimensions could serve as an index of attunement and alliance strength, whereas persistent mismatches might forecast dropout or stagnation. These propositions invite the integration of process coding, linguistic analysis, and computational modeling to trace dimensional dynamics over time. Embedding such metrics within ongoing clinical trials could provide the empirical grounding necessary to evaluate, and refine, the Dimensional Model as both explanatory and predictive framework.

The Dimensional Model introduces a genuinely systematic language for describing mental activity without collapsing the complexity of the therapeutic encounter. Its main advantage lies in structural precision: it makes visible the transitions that usually remain implicit in psychodynamic formulations. This precision allows for empirical coding and comparison across cases, something few meta-theoretical models achieve.

Yet the model’s greatest contribution is methodological rather than doctrinal: it provides a grammar of psychological movement that different theoretical schools can use without abandoning their own metaphors. In this sense, its integrative power rests not on theoretical synthesis but on shared observability, a common map for studying how mind and meaning transform in dialogue.

Precisely because it imposes structure, the Dimensional Model inevitably excludes what resists formalization. Any segmentation of therapy into discrete units simplifies the fluid, co-created nature of human dialogue. The model therefore clarifies mechanisms of movement but cannot capture the emergent, non-rule-bound transformations that constitute the art of therapy.

Another limitation concerns scope: the framework currently addresses the organization of psychic discourse, not its developmental, somatic, or neurobiological substrates. Nor does it account for the cultural or linguistic variability that may shape dimensional expression. These boundaries are not flaws but define the epistemic domain of the model: a map of mental functioning, not a map of mind in total. Future elaborations may extend the architecture to include embodied, temporal, and social dimensions, but within its present formulation, the model should be judged by its explanatory precision, not its comprehensiveness.

Beyond these practical considerations, the model carries inherent conceptual constraints embedded within each of its structural components (the five dimensions, the cascade, and their operational principles). Future development may involve expanding the model to encompass additional domains such as body, time, intersubjectivity, or even chaos. These could help delineate the model’s boundaries and reveal what stirs between or destabilizes its dimensions, thereby enriching our understanding of psychic motion beyond its current architecture.

Similarly, the Dimensional Cascade may include yet unrecognized transitional zones, fractures, or peripheral dimensions that influence inner equilibrium and the system’s capacity for self-renewal. Likewise, further inquiry may uncover latent or implicit principles of operation that remain outside the current framework but subtly shape the flow between dimensions, challenge continuity, or stimulate dynamic reorganization.

Taken together, these limitations should not be regarded as weaknesses but as generative invitations. They call for continued conceptual refinement, empirical exploration, and methodological innovation in testing and expanding the Dimensional Model of the psyche.

Recognizing these limits clarifies the model’s status: not a closed system of explanation, but an analytic lens whose strength lies in the disciplined articulation of what can be observed, rather than in the promise of theoretical totality. Its primary contribution may therefore lie in offering a shared conceptual grammar through which diverse psychological processes can be rendered intelligible within a single structural vocabulary.

Efforts to integrate psychology’s disparate paradigms are not new. Henriques’s Tree of Knowledge framework Henrique’s, 2004, 2011 proposed a hierarchical unification of natural and social sciences through levels of complexity, situating psychology as the “joint point” between biology and culture. The Dimensional Model shares this integrative ambition but differs in scope and focus: rather than describing a phylogenetic hierarchy of knowledge systems, it delineates the functional architecture of the psyche itself, the dynamic transitions through which subjective life unfolds from being to action. Its concern is phenomenological and processual rather than epistemological or disciplinary.

Hayes and Hofmann’s (2021) Process-Based Therapy (PBT) movement represents a second major integrative current, replacing schools of therapy with empirically defined change processes. The Dimensional Model complements this approach by supplying a meta-structural grammar of those processes. Where PBT enumerates mechanisms of change (e.g., cognitive flexibility, attentional control), the Dimensional framework articulates the underlying configurations of mental functioning within which such mechanisms operate and transform. It thus offers a phenomenological topology to accompany the nomothetic taxonomy of PBT.

Dynamic-systems formulations (e.g., Schiepek and Tschacher, 2020) likewise emphasize self-organization, feedback, and attractor states in psychotherapy. The Dimensional Model converges with this perspective in portraying the psyche as a non-linear system governed by principles of equilibrium and flexibility, yet diverges by grounding these dynamics in experiential and semantic rather than purely mathematical terms. It translates systemic regulation into clinically observable movements between dimensions.

Finally, Damasio’s (2021) neurophenomenological synthesis underscores the hierarchical emergence of mind from bodily regulation to consciousness. The Dimensional Model parallels this ascending organization but extends it beyond neural description to the symbolic and intersubjective field, framing the same continuity from a first-person psychological standpoint.

In this respect, the Dimensional Model positions itself as a bridging meta-framework: not a replacement for these integrative paradigms but a phenomenologically precise matrix linking subjective experience, clinical practice, and empirical observation within a single, dynamically regulated structure of mind.
