Abstract
The attractor framework proposes that persistence under perturbation is a fundamental marker of reality, with corrective permeability (κ) serving as a proposed multi-dimensional measure of a system’s capacity to return to its attractor after perturbation. Bonet-Luz et al. (2020) developed Symmetric Projection Attractor Reconstruction (SPAR), a patented mathematical method that reformulates the entire electrocardiogram (ECG) waveform into a bounded, symmetric, 2-dimensional attractor and extracts quantitative features from it. Applied to mice with an Scn5a+/- mutation linked to Brugada syndrome, SPAR features achieved 96% classification accuracy—substantially outperforming standard ECG intervals and amplitudes. This paper identifies structural parallels between SPAR’s attractor-based analysis and the attractor framework. The SPAR attractor is a concrete, computable attractor derived from a physiological signal, and a provisional mapping is proposed between specific SPAR features and proposed components of κ. The parallels are post‑hoc and do not constitute independent validation of the framework. The framework’s κ remains qualitatively defined; this mapping is offered as a contribution to its ongoing development.
1. Introduction: Attractor-Based ECG Analysis
The attractor framework (Galida, 2026a, self‑published May 2026 at fantasyattractor.com; no DOI) proposes that dissipative attractors—stable configurations toward which systems converge and from which they resist displacement—are the fundamental units of persistent organization across physical, biological, cognitive, and social domains. Corrective permeability (κ) is a proposed multi-dimensional measure of a system’s capacity to return to its attractor after perturbation. The framework distinguishes between the attractor (the invariant set of states toward which the system converges) and the basin (the set of initial conditions that converge to that attractor). In the present paper, we use “attractor” in the standard dynamical systems sense and note where the framework’s usage aligns or diverges.
In 2020, Bonet-Luz, Aston, Nandi, and colleagues published a study in Heart Rhythm O2 (Elsevier) applying Symmetric Projection Attractor Reconstruction (SPAR) to murine electrocardiograms (Bonet-Luz et al., 2020). SPAR is a patented mathematical method that reformulates the entire ECG waveform into a bounded, symmetric, 2-dimensional attractor, preserving all available waveform morphology rather than extracting only a few fiducial points. The method was applied to distinguish wild-type mice from those carrying an Scn5a+/- mutation linked to Brugada syndrome, a hereditary condition associated with sudden cardiac death.
The study did not cite the attractor framework and was conducted within the established traditions of biomedical signal processing, nonlinear dynamics, and machine learning. This paper identifies structural parallels between SPAR’s attractor-based analysis and the attractor framework. The parallels are post‑hoc and do not constitute independent validation.
2. The SPAR Method
SPAR generates a 2-dimensional attractor from approximately periodic signals such as ECG, blood pressure, or photoplethysmogram waveforms. The method determines an average cycle length from the signal, sets a time delay parameter as one-third of that cycle, and plots the data in a bounded box using a symmetric projection. The resulting attractor is a compact, easily visualized representation of the entire waveform morphology, overlaid with a density map indicating which regions are visited more or less frequently. The method factors out changes in heart rate and baseline variation to concentrate on waveform morphology.
For murine lead I and II ECG signals, the SPAR attractor typically exhibits 3 long arms predominantly representing the R peak, with deep S peaks and sometimes deep Q peaks producing shorter arms in the opposite direction, yielding an attractor with up to 6 arms in total (Figure 1 of the original paper). The central core region reflects T-wave and P-wave morphologies.
From this attractor, Bonet-Luz et al. extracted 74 manually defined features relating to the density, size, and symmetry of the attractor, along with the average heart rate and a vertical normalization scaling factor. These features were used in a k-nearest neighbors classifier (k=3) with leave-one-animal-out cross-validation.
The dataset comprised ECG recordings from 42 anesthetized mice (39 lead I, 39 lead II) of varying genotype (wild-type vs. Scn5a+/-), sex, and age. Each signal was divided into 13 non-overlapping 10-second windows, yielding 1,014 records for classification. Standard ECG intervals (7) and amplitudes (6) were also extracted for benchmarking. It is important to note that the effective sample size for the classification is 42 animals, not 1,014 windowed records, and the 96% classification accuracy has not yet been independently replicated in a separate cohort.
3. Results Summary
The SPAR features alone achieved 87.2% classification accuracy for genotype (majority vote), outperforming ECG intervals (74.3%) and intervals plus amplitudes (85.9%). The highest accuracy (96.2%) was obtained by combining all features—SPAR, intervals, and amplitudes. For sex and age classification, SPAR features similarly outperformed standard measures.
The machine learning algorithm selected 16 SPAR features out of 20 in the combined model, with the remaining 4 being the ST height, P and R amplitudes, and the PR interval. The density distribution and symmetry in the arm regions of the attractor were the most discriminative SPAR features. The ST height—a known marker for Brugada syndrome—was selected in both feature groups that included amplitudes.
The authors concluded that the ECG carries sufficient information to detect the Scn5a+/- mutation, but that enhanced analysis techniques are required to extract it. Standard interval and amplitude measures fail to capture the relevant signal because the mutation’s effects are distributed across the entire waveform morphology, not concentrated at isolated time points.
4. Structural Parallels with the Attractor Framework
4.1 The SPAR Attractor as a Cardiac Attractor. The SPAR method generates a bounded, stable 2-dimensional attractor from the ECG signal. This attractor is a compact representation of the cardiac system’s dynamical state—a region in state space toward which trajectories converge and around which they organize. In the attractor framework’s vocabulary, this is an attractor generated by a dissipative system (the beating heart, maintained by continuous metabolic energy input). The attractor’s density distribution, arm structure, and symmetry reflect the stability and structural coherence of this configuration.
4.2 SPAR Features as Candidate Proxies for Corrective Permeability (κ). The framework proposes κ as a multi-dimensional measure of a system’s capacity to return to its attractor after perturbation. A healthy heart with normal ion channel function has a deep, stable attractor—it responds to perturbations and returns rapidly to its baseline rhythm. The Scn5a+/- mutation degrades sodium channel function, making the cardiac tissue more vulnerable to arrhythmia. This degradation manifests as measurable changes in the SPAR attractor.
A provisional mapping between specific SPAR feature categories and proposed components of κ is offered below. This mapping is hypothetical and has not been formally derived; it is presented as a structural analogy to be tested in future work. The κ component labels in this table are introduced here for exploratory purposes and are not yet formalized in the primary framework document (Galida, 2026a); they are subject to revision pending formal axiomatization of κ.
| SPAR Feature Category | What It Measures in the Attractor | Candidate κ Component (provisional) |
|---|---|---|
| Density distribution (core) | Frequency of trajectory visits to central attractor region | Attractor core stability: a dense core indicates a stable, frequently occupied equilibrium |
| Density distribution (arms) | Frequency of trajectory visits to peripheral regions | Perturbation response: arm density reflects excursions from equilibrium |
| Symmetry features | Left-right symmetry of attractor arms | Recovery symmetry: asymmetric arms may indicate directional perturbation bias or conduction abnormality |
| Arm structure | Length, width, and number of attractor arms | Global waveform integrity: degraded arm structure reflects disrupted cardiac conduction |
The 96% classification accuracy (pending independent replication) demonstrates that these attractor-derived proxies capture diagnostically relevant information that standard interval measures miss. Whether this information corresponds specifically to κ, or to more general signal properties, cannot be determined without a formal derivation of κ from the framework’s axioms.
4.3 Multi-Dimensional Feature Combination. The framework proposes that κ is multi-dimensional—no single measure fully captures a system’s corrective permeability. The SPAR results are consistent with this principle: combined features outperformed any individual feature set. However, this result is also expected under standard machine learning practice, where feature combination typically improves classification performance. The result is therefore consistent with the framework without uniquely supporting it. The specific finding that SPAR features (16/20) dominated the combined model suggests that attractor-derived measures carry more discriminative information than point-based measures for this particular mutation. Whether this dominance generalizes to other perturbations and other physiological systems is an open empirical question.
4.4 Normalization as Signal Isolation. The SPAR method normalizes the signal to factor out changes in heart rate and baseline variation, concentrating on waveform morphology. In the framework’s terms, this is a methodological step that isolates the attractor’s structural properties from confounding variables. Heart rate is influenced by autonomic tone, physical activity, and respiratory cycle—perturbations that can obscure the measurement of the attractor’s intrinsic stability. SPAR’s normalization yields a cleaner representation of the attractor. However, this normalization step is standard practice in many signal processing methods and does not constitute a distinctive parallel with the framework.
5. Limitations
This mapping is post‑hoc. The parallels identified here are structural analogies, not independent evidence for the framework. The provisional κ-proxy mapping in Section 4.2 is hypothetical and has not been formally derived from the framework’s axioms. The κ component labels used in the provisional mapping table (e.g., “attractor core stability,” “recovery symmetry,” “global waveform integrity”) are introduced in this paper for exploratory purposes and are not yet formalized in the primary framework document (Galida, 2026a). They are subject to revision pending formal axiomatization of κ.
The framework’s κ remains qualitatively defined. A formal derivation specifying the state variables, the attractor geometry, and the perturbation response function is required before the SPAR feature mapping can be evaluated as more than a structural analogy.
The 96.2% classification accuracy was obtained from a single study of 42 mice (effective N=42, despite 1,014 windowed records). Independent replication in a separate cohort has not been performed. The accuracy figure should be interpreted with appropriate caution.
The SPAR method was developed for approximately periodic signals and has been validated on cardiovascular waveforms. Its applicability to the non‑periodic attractors the framework describes in cognitive and social domains is unknown.
The attractor framework is self‑published and has not undergone independent peer review.
6. Falsifiability Conditions
The following observations would weaken or invalidate the parallels drawn here:
- Disconfirming observation 1: If SPAR features were shown to be uncorrelated with independently validated measures of cardiac resilience or arrhythmia susceptibility in a larger, independent cohort, the κ proxy interpretation would lose its empirical anchor.
- Disconfirming observation 2: If the SPAR attractor’s classification accuracy for the Scn5a+/- mutation were shown to derive primarily from features unrelated to attractor geometry (e.g., heart rate alone or predominantly heart rate), the attractor interpretation would be substantially weakened.
- Disconfirming observation 3: If alternative signal processing methods with no attractor reconstruction component achieved equal or higher classification accuracy using the same data, the attractor interpretation would not be uniquely supported.
Affirmative predictions:
- Primary prediction: If the provisional κ-proxy mapping in Section 4.2 captures genuine components of corrective permeability, then pharmacological interventions that improve cardiac ion channel function (e.g., sodium channel modulators) should produce measurable shifts in specific SPAR features—density, symmetry, arm structure—toward the wild-type baseline. Conversely, interventions that degrade ion channel function should shift these features away from the baseline. This prediction is testable using pre‑ and post‑intervention ECG recordings with the same SPAR methodology.
- Secondary prediction: If attractor-derived features are more sensitive to κ-relevant perturbations than point-based measures, then SPAR features should show greater sensitivity to these pharmacological interventions than standard ECG intervals and amplitudes. This secondary claim is more speculative; failure of the secondary prediction while the primary prediction holds would suggest that SPAR features track relevant physiological changes without uniquely capturing κ as distinct from other measures.
7. Conclusion
The SPAR method developed by Bonet-Luz et al. (2020) generates a mathematically defined attractor from ECG signals that encodes diagnostically relevant information about cardiac stability. A provisional mapping between SPAR features and proposed components of corrective permeability (κ) has been offered, along with primary and secondary affirmative predictions. The 96% classification accuracy for a disease-causing mutation demonstrates that attractor-based features capture information about system integrity that standard point-based measures miss. These parallels are structural analogies, not independent validation. The framework remains a self‑published, preliminary research program. This mapping is a contribution to its ongoing development.

Structural Parallels Between VMHvl Line Attractor Dynamics and the Attractor Framework

Abstract
The attractor framework proposes that persistence under perturbation is a fundamental marker of reality, with corrective permeability (κ)—a proposed measure of the rate at which a system returns to its basin after perturbation—serving as a key diagnostic variable. Nair et al. (2023) discovered an approximate line attractor in the ventromedial hypothalamus (VMHvl) of mice that encodes an escalating aggressive state. The line attractor exhibits a single integration dimension with a long time constant that correlates with individual differences in aggressiveness. This paper identifies structural parallels between the VMHvl line attractor and the attractor framework. Both frameworks draw on a shared dynamical‑systems vocabulary; the parallels are therefore a consistency check, not independent corroboration. The integration dimension’s time constant is proposed as a candidate structural analogue for the inverse of corrective permeability (κ ~ 1/τ), grounded in the perturbation‑recovery events directly observable in Nair et al.’s data. The paper specifies falsifiability conditions, including an affirmative, testable prediction, and acknowledges the framework’s preliminary, self‑published status.
1. Introduction: Shared Vocabulary, Not Convergence
The attractor framework (Galida, 2026a, self‑published May 2026 at fantasyattractor.com; no DOI) proposes that dissipative attractors—stable basins toward which systems converge and from which they resist displacement—are the fundamental units of persistent organization across physical, biological, cognitive, and social domains. Corrective permeability (κ) is a proposed measure of the rate at which a system returns to its basin after perturbation. The framework’s concepts were developed independently through philosophical inquiry, systems theory, and N=1 self‑engineering experiments—a methodology in which the author systematically tracked physiological, cognitive, and behavioral responses to targeted interventions on himself, generating preliminary data that informed the framework’s development but does not constitute independent validation.
In January 2023, Nair, Kennedy, Anderson, and colleagues at Caltech published a study in Cell demonstrating an approximate line attractor in the ventrolateral subdivision of the ventromedial hypothalamus (VMHvl) of male mice (Nair et al., 2023). Using calcium imaging and dynamical systems modeling, they showed that neural population activity in VMHvl converges toward and progresses along a stable trough in neural state space, and that the position of activity along this trough correlates with the intensity of aggressive behavior.
Both the framework and the Nair et al. study use the vocabulary of dynamical systems—”attractor,” “basin,” “time constant.” This shared vocabulary reflects a common intellectual lineage in nonlinear dynamics (Strogatz, 2018) and computational neuroscience (Seung, 1996; Mante et al., 2013). The parallels identified in this paper are therefore a consistency check, not independent corroboration. The framework imported these concepts; it did not invent them. The relevant question is whether the framework’s specific claims—about κ, basin depth, and cross‑domain generalization—find structural analogues in the VMHvl circuit that are non‑tautological. This paper explores that question while acknowledging its limitations.
2. The VMHvl Line Attractor
Nair et al. (2023) fit recurrent switching linear dynamical system (rSLDS) models to calcium imaging data from VMHvlEsr1 neurons during social interactions. Their unsupervised analysis revealed a dominant integration dimension with a time constant exceeding 50 seconds—significantly longer than all other dimensions. This dimension accounted for approximately 20% of the total variance in neural activity.
The integration dimension exhibited slow ramping as aggression escalated, rising from low values during sniffing to intermediate values during dominance mounting to high values during attack. Once elevated, activity persisted for tens of seconds after the intruder was removed, decaying slowly along the attractor. When a new intruder was introduced, neural activity was transiently displaced from the attractor but rapidly returned to its previous position along the trough.
These perturbation‑and‑recovery events—intruder removal producing slow decay, new intruder introduction producing transient displacement followed by rapid return—are directly observable in Nair et al.’s Figure 3C–3D and Supplementary Videos 1 and 2. They provide an empirical window into the system’s post‑perturbation dynamics and are the natural data from which to estimate any candidate measure of corrective permeability.
Individual mice varied substantially in the time constant of their integration dimension. This variation was strongly correlated with the fraction of time each mouse spent attacking (r² = 0.77, n = 14 animals). Mice with longer time constants were more aggressive. It should be noted that alternative explanations for this correlation exist: testosterone and other androgens influence both VMHvl activity and aggressiveness, and individual differences in circuit excitability could produce both a longer time constant and more aggressive behavior. The time constant–aggression link is robust but not uniquely explained by attractor depth.
3. Structural Parallels with the Attractor Framework
3.1 The Line Attractor as a Basin. The line attractor is a stable region of neural state space toward which population activity converges and along which it progresses slowly. This is structurally analogous to the framework’s concept of a basin—a configuration toward which the system gravitates and from which it resists displacement.
3.2 Integration Time Constant and Corrective Permeability (κ). The framework defines κ as a proposed measure of the rate at which a system dissipates perturbation and returns to its basin. As currently formulated, κ is qualitative and lacks a formal derivation from the framework’s axioms. Dimensional analysis suggests a candidate mapping: corrective permeability has dimensions of inverse time (s⁻¹), while the integration time constant τ has dimensions of time (s). A natural structural analogue is κ ~ 1/τ. Under this mapping, longer time constants (slower decay) correspond to lower κ (deeper persistence), and shorter time constants correspond to higher κ (faster recovery).
This dimensional argument is necessary but not sufficient. What recommends the specific mapping κ ~ 1/τ over other inverse‑time quantities in the system (such as firing rates or synaptic decay constants) is its functional role: κ should specifically track the post‑perturbation recovery rate. Nair et al.’s data contain perturbation‑and‑recovery events—intruder removal and reintroduction—where the time course of return to the attractor can be observed. The integration time constant τ directly governs the rate of this return. It is therefore the natural candidate for a functional, not merely dimensional, analogue. This mapping is a hypothesis, not a derivation. It is offered as a bridge for future formal work.
The observed correlation between the time constant and individual differences in aggressiveness is consistent with the framework’s prediction that variation in κ may be associated with variation in persistent behavioral traits. It does not independently confirm that prediction.
3.3 Graded Position Along the Attractor as Intensity Encoding. The framework describes attractors as graded landscapes: a system can occupy different positions within a basin, each corresponding to a different state intensity. The VMHvl line attractor demonstrates this property: sniffing, dominance mounting, and attack occur at progressively higher values along the integration dimension.
3.4 Persistence and Resistance to Perturbation. When the intruder is removed, activity decays slowly rather than collapsing immediately. When a new intruder is introduced, activity is transiently displaced but returns to its prior position along the trough. This is a structural analogue of persistence under perturbation.
3.5 Leaky Integration Is Not Thermodynamic Dissipation. Nair et al. describe the VMHvl attractor as “leaky”—activity decays over tens of seconds rather than persisting indefinitely. The attractor framework uses “dissipative” in a thermodynamic sense: a dissipative system exports entropy to its environment and is maintained by continuous energy flow. These are distinct concepts. A conservative (non‑dissipative) system could, in principle, exhibit finite decay times under certain conditions. The framework’s “dissipative attractor” and the neurobiological “leaky integrator” share a structural property—finite persistence—but they are not identical in their underlying mechanisms. This distinction should be kept in view to avoid terminological conflation.
4. Rotational Dynamics as a Contrasting Geometry
Nair et al. also analyzed MPOA, a different hypothalamic nucleus controlling mating. They found no line attractor. Instead, MPOA exhibited rotational dynamics—fast, sequential activity time‑locked to specific behavioral actions. This contrast demonstrates that not all neural circuits exhibit line attractor geometry.
The framework can accommodate this contrast as an instance of a broader principle: circuits encoding scalable, persistent states (such as the intensity of aggressive motivation) are predicted to exhibit line or point attractor geometries, while circuits encoding sequential action programs (such as the progression from sniffing to mounting to intromission) are predicted to exhibit rotational or heteroclinic dynamics. The VMHvl/MPOA contrast is consistent with this generalization. However, the generalization itself is post‑hoc in this case, and the framework does not yet make a non‑obvious, advance prediction about which geometry should appear in which specific nucleus. The contrast is therefore a productive organizing principle for future neural circuit taxonomy, not a confirmed prediction.
5. Limitations
This mapping is post‑hoc. The parallels identified here are structural analogies, not independent evidence for the framework. The shared dynamical‑systems vocabulary renders some degree of parallel expected rather than surprising.
The framework’s κ remains qualitatively defined. A formal derivation from the framework’s axioms—specifying the state variables, the basin geometry, and the perturbation response function—is required before the κ ~ 1/τ mapping can be evaluated as more than a dimensional and functional suggestion. Within the framework, κ is proposed as an attractor‑level property: it characterizes the stability of the system’s basin, not the strength of individual perturbations or the activity of specific components. It is derived from the persistence of a configuration under perturbation, measured as the rate of return to the attractor after displacement. A full formal derivation remains a task for future work.
The attractor framework is self‑published and has not undergone independent peer review. The foundational paper (Galida, 2026a) was published on fantasyattractor.com in May 2026 and is not archived with a DOI, which limits the independent verifiability of the framework’s claims and the timeline of its development.
6. Falsifiability Conditions
The following observations would weaken or invalidate the parallels drawn here:
- Disconfirming observation 1: If the VMHvl integration dimension’s time constant were shown to be uncorrelated with behavioral persistence or recovery from perturbation after controlling for circuit excitability, the κ analogy would lose its empirical anchor.
- Disconfirming observation 2: If line attractor dynamics in VMHvl were shown to be entirely input‑driven with no intrinsic persistence, the basin analogy would fail.
- Disconfirming observation 3: If alternative models of aggressiveness (e.g., androgen‑mediated circuit excitability without attractor dynamics) were shown to explain the data with equal or greater parsimony, the attractor interpretation would be weakened.
Affirmative prediction: If κ ~ 1/τ is more than a dimensional coincidence, then pharmacological or optogenetic manipulations that prolong the integration time constant should produce corresponding increases in aggressive persistence—the tendency to maintain an escalated aggressive state after the stimulus is removed—without necessarily lowering the threshold for aggressive initiation. Conversely, manipulations that shorten the time constant should produce corresponding decreases in aggressive persistence. This dissociation between persistence and initiation is specifically predicted by the framework’s claim that κ governs recovery from perturbation, not the threshold for entering the state, and distinguishes the attractor interpretation from alternative models in which circuit excitability uniformly modulates both initiation and persistence. Aggressive persistence should be operationalized as the latency to cease aggressive posturing or the duration of elevated VMHvl activity following intruder removal, rather than as the overall fraction of time spent attacking, which confounds initiation and persistence. It should be noted that experimentally dissociating these phases in the VMHvl circuit may be technically challenging, as the neurons involved are active during both ramp‑up and post‑attack periods. A manipulation protocol capable of selectively targeting the post‑stimulus interval is required; without this, a null result would be uninterpretable.
7. Conclusion
The VMHvl line attractor discovered by Nair et al. (2023) exhibits structural parallels with the attractor framework’s description of a graded, persistent basin. These parallels are consistency checks, not independent corroboration, given the shared dynamical‑systems vocabulary. A dimensional and functional mapping κ ~ 1/τ is proposed, grounded in the perturbation‑recovery events observable in Nair et al.’s data. The MPOA contrast is consistent with a framework‑based generalization about attractor geometry and behavioral function. The paper specifies both disconfirming and affirmative testable predictions. The framework remains a self‑published, preliminary research program. This mapping is a contribution to its ongoing development.

Structural Analogies Between Psychodynamic Attractor States and the Attractor Framework
Robert Galida
Independent Researcher
June 2026
fantasyattractor.com
Abstract
The attractor framework proposes that persistence under perturbation is a fundamental marker of reality, using corrective permeability (κ) to distinguish reality‑aligned from fantasy attractors. A recent clinical article by James Tobin (2026) describes psychological suffering as organized around recurring “attractor states”—stable patterns of emotional organization that resist insight, are embodied, and function as attempts at stability. This paper offers a post‑hoc mapping between Tobin’s observations and the attractor framework. The parallels are structural analogies, not independent clinical corroboration. Both perspectives draw on a shared dynamical‑systems vocabulary, and the mapping is offered as evidence of cross‑disciplinary convergence rather than validation. The paper explicitly addresses the limitations of a self‑published framework based on N=1 self‑engineering, and specifies conditions under which the mapping would be disconfirmed.
1. Introduction: A Shared Vocabulary, Not Confirmation
The attractor framework (Galida, 2026a) is a naturalistic ontology developed independently through philosophical inquiry, systems theory, and N=1 self‑engineering experiments. Its central diagnostic concepts are corrective permeability (κ) and the distinction between reality‑aligned and fantasy attractors. The framework is self‑published and has not undergone independent peer review.
In May 2026, clinical psychologist James Tobin published “The Psychology of ‘Attractor States'” on his professional website. Tobin draws on psychodynamic theory, attachment research, affective neuroscience, and dynamical systems theory to describe how emotional suffering becomes organized around recurring states that resist change. His article does not cite the attractor framework.
This paper identifies structural parallels between Tobin’s account and the framework. It does not claim that Tobin’s clinical observations independently corroborate the framework. Both Tobin and the framework explicitly draw on dynamical systems theory, and the shared vocabulary of “attractors,” “basins,” and “perturbation” reflects this common intellectual lineage. The mapping is a post‑hoc exercise in identifying convergent themes across disciplines.
2. Tobin’s Psychodynamic Attractor States
Tobin’s article describes several features of emotional suffering that will be familiar to readers of dynamical systems literature:
2.1 Attractor States as Recurring Configurations. Tobin describes an attractor not as a single behavior or belief but as a recurring configuration toward which the emotional system gravitates—an entire organization of feeling, bodily expectation, attention, memory, and relational anticipation that emerges repeatedly under similar conditions.
2.2 Persistence Despite Insight. A central clinical puzzle for Tobin is that patients often understand their patterns intellectually, sometimes with considerable sophistication, yet the old emotional organization returns with force when certain emotional conditions arise. Insight alone rarely dislodges these deeply embedded patterns.
2.3 Embodiment and Automaticity. Tobin emphasizes that these patterns are not merely cognitive. They become woven into bodily readiness, autonomic regulation, procedural memory, emotional timing, and unconscious relational expectation—the body learns what to anticipate long before conscious reflection arrives.
2.4 Symptoms as Emotional Solutions. Tobin argues that many symptoms are not random pathology but tragic attempts at psychological stability. They persist, despite their cost, because they have served to preserve some continuity of self under conditions that once felt emotionally overwhelming.
2.5 Destabilization and the Fear of Change. When old attractors begin to loosen, patients experience a vulnerable intermediate state. They are no longer fully stabilized by the older organization, yet have not developed sufficient trust in newer ways of experiencing themselves. The temptation to retreat to the familiar attractor is strong.
2.6 The Goal of Therapy: Expanded Flexibility. Tobin’s vision of psychological health is not the elimination of suffering but the gradual expansion of flexibility and reflective space within the personality—the capacity to move among emotional states without being trapped by any one of them.
3. Structural Parallels with the Attractor Framework
3.1 Attractor States as Basins. Tobin’s recurring emotional configuration toward which the system gravitates is structurally identical to the framework’s concept of a basin. Both describe a stable state the system returns to automatically.
3.2 Insight Failure as Low Corrective Permeability. The framework defines a fantasy attractor as a system with low κ that resists updating. Tobin’s observation—that insight alone rarely dislodges deeply embodied patterns—maps onto this. The cognitive insight is a perturbation that fails to land because the attractor is embedded in non‑cognitive systems.
A note on circularity. If κ is measured by flexibility outcomes, and flexibility is what κ is claimed to predict, the mapping is circular. An operationally independent measure of κ—for example, response latency to belief‑updating tasks, physiological perturbation recovery rates, or other proxies not identical with therapeutic outcome—would be required to break this circularity. No such measure has yet been validated. The current mapping relies on functional analogy, not independent measurement.
3.3 Symptoms as Stability Attempts: A Conceptual Distinction. Tobin claims symptoms persist because they function to maintain stability (a teleofunctional claim). The framework claims persistence under perturbation is the mark of the real (an ontological criterion). The two claims overlap—both describe systems that resist perturbation—but they are not identical. A symptom could persist for functional reasons without that persistence carrying ontological significance. The mapping here is of practical convergence, not logical identity. Whether the framework’s ontological claim can be grounded in or distinguished from teleofunctional accounts of persistence is a question for future theoretical work.
3.4 Destabilization as Basin Transition. The vulnerable intermediate state between old and new attractors is a phase transition between basins—a prediction the framework makes about any dissipative system under perturbation.
3.5 Therapeutic Flexibility as High Corrective Permeability. Tobin’s vision of health—flexibility, the capacity to experience states without being organized by them—is high κ. A reality‑aligned attractor absorbs perturbation and updates rather than sealing.
4. Independence, Shared Lineage, and the Limits of Convergence
Tobin and the framework draw on overlapping intellectual traditions. Tobin cites Lewis (2000) and Thelen & Smith (1994) from dynamical systems psychology; the framework draws on Ruelle, Prigogine, and the neuroscience of reward. The shared vocabulary (“attractor,” “basin”) reflects this common upstream source, not independent discovery.
The convergence is therefore weaker than it would be between genuinely independent methods. Both parties applied dynamical systems concepts to their respective domains. The fact that they arrived at similar structural descriptions is interesting but expected: the vocabulary constrains the output. This paper does not overinterpret that convergence.
5. Addressing the N=1 Foundation
The attractor framework was developed partly through N=1 self‑engineering experiments. This methodology introduces specific risks: motivated reasoning, experimenter‑subject confound, and non‑transferability. A single‑subject design cannot distinguish between genuinely generalizable dynamics and idiosyncratic personal response.
Disclosure of these risks is not mitigation. The framework’s claims remain untested by independent, blinded, or large‑N studies. The clinical parallels described here are suggestive but cannot substitute for such testing. Readers should weigh the framework’s claims accordingly.
6. Falsifiability: What Would Disconfirm This Mapping?
A framework that diagnoses sealed attractors must specify its own disconfirmation conditions. For the present mapping, the following observations would weaken or invalidate the analogies drawn:
- Disconfirming clinical observation: A well‑controlled study showing that therapeutic flexibility (the capacity to move among emotional states) is uncorrelated with measures of belief‑updating or perturbation recovery would break the link between Tobin’s flexibility and κ. Currently, no standardized instruments exist to perform this test. The condition is stated in principle; its operationalization requires measurement development beyond the scope of this paper.
- Disconfirming dynamical finding: Evidence that the attractor‑like patterns Tobin describes are not truly self‑reinforcing but are maintained entirely by external environmental contingencies, with no internal basin structure, would undermine the “basin” analogy. Distinguishing internal basin dynamics from environmental maintenance is a hard empirical problem in dynamical systems psychology, and the tools to resolve it are not yet standardized.
- Superior alternative framework: If a competing model explains Tobin’s clinical observations equally well without requiring the attractor framework’s ontological commitments, parsimony favors the simpler account. Acceptance and Commitment Therapy’s psychological flexibility model, for instance, predicts that cognitive fusion and experiential avoidance produce the rigidity Tobin describes—without appealing to attractor dynamics. Predictive processing accounts of emotional rigidity similarly provide alternative mechanisms. The present paper does not adjudicate between these rival frameworks; it offers the attractor framework as one candidate account among several.
These conditions are not met by the current paper, which offers only preliminary analogies.
7. Conclusion
James Tobin’s 2026 clinical article on psychodynamic attractor states and the attractor framework exhibit expected structural parallels, given their shared dynamical‑systems heritage. Both describe recurrent, embodied patterns that resist perturbation and that therapeutic or corrective processes can gradually loosen. These parallels are analogical, not evidentiary. The framework remains a self‑published, N=1‑grounded research program awaiting independent empirical testing. This mapping is a contribution to its ongoing development.

Abstract
This paper presents a relational view of time based on the attractor framework.
We argue that two very different kinds of attractors work together to create what we call time:
- Conservative attractors (electrons, neutrinos, protons) act as metronomes. They provide a steady, repeatable rhythm – a ruler for measuring duration.
- Dissipative attractors (living cells, minds, societies) act as memory. They accumulate irreversible changes, giving time its direction.
Time is not a mysterious substance. It is the coupling between these three fundamental metronomes and the irreversible flow of memory. What binds all dissipative systems – from a bacterium to a brain to a galaxy – is the continuous recycling of the same three eternal metronomes.
This view offers a conceptual account of how clocks work, why time has an arrow, and how aging, entropy, and history fit together.
The dance of time has three metronomes and a memory.
1. Two Classes of Persistence, Two Roles for Time
In the attractor framework, everything that persists does so by resisting disturbance. We identify two distinct types of persistent structures, each giving rise to a different aspect of time.
1.1 Conservative Attractors – The Metronome
Conservative attractors are protected by physical conservation laws (charge, baryon number, energy). They are:
- Eternal – they do not age or decay (or are effectively stable on all observable timescales).
- Time‑symmetric at the level of intrinsic persistence – their existence as attractors is symmetric under time reversal, though some interactions (weak force) violate CP and thus T.
- Type‑identical – every electron has the same Compton frequency; every neutrino mass eigenstate has an invariant (though not yet precisely measured) frequency.
Because of these properties, conservative attractors serve as reference standards for duration – metronomes. The international definition of the second is literally a fixed number of such ticks.
1.2 Dissipative Attractors – Memory
Dissipative attractors (cells, minds, ecosystems, societies) are different:
- They require a continuous flow of energy and must export entropy.
- Their dynamics are irreversible – you cannot return to a past microstate without enormous cost.
- This irreversibility creates a directional arrow: before and after, past and future.
- They accumulate memory – irreversible state changes that persist and affect future behaviour.
Memory = irreversible accumulated state change (inscription). Examples: synaptic plasticity, scars, fossil records, cultural archives, radioactive decay (the daughter nucleus retains a record of the parent’s disintegration).
2. The Three Metronomes: Our Most Fundamental Clocks
The Standard Model contains many particles, but only three classes are absolutely or effectively stable and serve as fundamental metronomes. The photon is not a metronome – it has zero rest mass, hence no rest‑frame Compton frequency. It is a mode of propagation, not a standalone persistent entity.
| Class / Particle | Symbol | Key Property | Role as Metronome |
|---|---|---|---|
| Electron | e⁻ | lightest charged lepton | Compton frequency ~1.24 × 10²⁰ Hz |
| Neutrino mass eigenstates (collectively) | ν₁, ν₂, ν₃ | neutral, tiny masses | Compton frequencies (mass‑dependent); effectively stable |
| Proton | p | lightest baryon | Compton frequency ~2.27 × 10²³ Hz; no observed decay |
These three classes form what the framework calls the eternal skeleton – the collection of conservative structures that persist without decay and provide the stable background against which dissipative change occurs.
Stability notes
- Proton decay has never been observed; lower limit on half‑life > 10³⁴ years – effectively eternal. The proton is composite, but its stability derives from baryon number conservation, not merely nuclear binding energy.
- Neutrinos oscillate between flavours, but the underlying mass eigenstates are stable on cosmological timescales. Their exact Compton frequencies are not yet known to metrological precision – only mass‑squared differences have been measured – but they are theoretically invariant.
These three metronomes do not need energy input to persist. Their frequencies are invariant (known for electron and proton; theoretically invariant for neutrinos). Any clock based on one agrees with any other after accounting for relativity, as confirmed by atomic clock comparisons.
3. Time as the Coupling Between Metronomes and Memory
Time is not a primitive substance. It is the relationship between the metronome ensemble and dissipative memory.
- The three metronomes provide a metric – an invariant ruler for “how much” duration has passed.
- Memory provides direction – which events are past, which are future.
- Without metronomes, change would be unmeasurable – no ruler.
- Without memory, change would be reversible and directionless – no before/after.
Both are necessary for what we operationally call time.
As a working placeholder, let the rate of memory inscription be dM/dt=f(M,ν), where ν is a characteristic metronome frequency and M is the current accumulated memory state. Two limiting cases anchor the idea:
- As ν→0 – no metronome – duration becomes undefined. Change occurs but cannot be quantified as a metric interval. This is the “no ruler” condition.
- As dissipation →0 – no memory – M remains constant. Change leaves no trace, so there is no before/after. This is the “no arrow” condition.
What binds all dissipative systems – a bacterial cell, a human brain, a galaxy, a social institution – is the continuous recycling of the same three eternal metronomes. Every dissipative system operates by exchanging electrons, protons, and neutrinos with its environment. The metronomes are the invariant substrate; the memory is the transient pattern. The coupling is the recycling.
Thus, time is not merely a coordinate; it is the ongoing, irreversible reconfiguration of eternal components into transient, memory‑bearing structures.
The three metronomes are time‑symmetric at the level of intrinsic persistence. The arrow of time comes from dissipative systems that accumulate history. Time is the coupling between these two regimes.
4. Thermodynamic Information Theory and Persistence
The persistence functional P(x) measures how deep an attractor basin is – formally, the depth of the basin in the system’s phase space (the energy or Lyapunov function value required to escape the basin). Higher P means a more stable attractor.
- In a dissipative attractor, maintaining memory requires continuous energy export to counteract thermal noise.
- Landauer’s principle: erasing one bit costs at least kBTln2 of free energy. Retaining memory against thermal fluctuations requires energy input.
We interpret P(x) as a measure of information retention: systems with higher P preserve mutual information between past and present for longer. The decay rate −P˙/P relates to entropy production, connecting the attractor framework to non‑equilibrium thermodynamics.
5. Consequences and Applications
- Clocks – Atomic clocks derive stability from electron transitions. The three metronomes guarantee cross‑calibration.
- Aging – Biological aging is the accumulation of irreversible memory, measured against metronomes like circadian rhythms.
- Critical slowing down – As a system approaches a bifurcation, −P˙/P decreases, providing early‑warning signals (rising autocorrelation, variance) in physiology, ecology, and social systems.
- Hysteresis in beliefs – Fantasy attractors exhibit hysteresis – the path of belief change differs when accumulating vs. removing evidence. The hysteresis loop area quantifies memory.¹
- Cosmological time – The cosmic microwave background is a memory of the early universe (here “memory” is metaphorical). Atomic clocks measure the duration since those imprints were formed.
¹ Fantasy attractor: in the attractor framework, a dissipative structure (typically a belief system) with abnormally low corrective permeability, resistant to updating despite counter‑evidence.
6. Relation to the Broader Attractor Framework
The metronome‑memory distinction is a special case of the conservative vs. dissipative attractor dichotomy. It sharpens the “eternal skeleton / transient dance” metaphor.
The three metronomes are the most fundamental layer of the eternal skeleton – the collection of conservative structures that persist without decay and provide the stable background against which dissipative change occurs.
The framework does not claim that time is “made of” attractors. It claims that the measurement and experience of time rely on the interaction of these two persistence regimes. Because every dissipative system continuously recycles the same eternal metronomes, all such systems are materially unified across space and time. That unity is what makes a universal, relational time possible.
7. Open Questions and Refinements
- Formalising P(x)P(x) – Rigorous derivation for deterministic (Lyapunov), stochastic (escape time), and information‑theoretic (surprisal) cases.
- Coupling equations – Specify dM/dt=f(M,ν). Can it be tested empirically?
- Category clarity – Conservative attractors span strict symmetry‑protected invariants (elementary particles) and emergent approximate invariants (clocks). Future work should stratify these.
- Falsifiability – Concrete falsifiers: a persistent system without dissipation, or a social attractor that never updates despite counter‑evidence.
- Relation to other relational accounts – Converges with Barbour (1999) and Rovelli (1996). The difference: the present framework identifies the two required poles (conservative metronomes providing metric invariance; dissipative memory providing direction) and grounds both in attractor dynamics.
8. Conclusion
Time is not a primitive. It is the relational coupling between:
- the three fundamental conservative attractor classes – electron, neutrino mass eigenstates (collectively), and proton – which provide invariant metric structure (the metronome), and
- dissipative systems that accumulate irreversible state inscription (memory).
What binds all dissipative systems – from a bacterium to a brain to a galaxy – is the continuous recycling of the same three eternal metronomes. The metronomes are the invariant substrate; memory is the transient pattern; time is the coupling.
This account respects how physics measures time, explains the arrow via entropy and information persistence, and offers transferable concepts across neuroscience, ecology, sociology, and AI.
The dance has three metronomes and a memory.
