The primary aim was to explore whether Movement Energy Analysis (MEA) combined with Cross-Recurrence Quantification Analysis (CRQA) can provide clinically meaningful insight into therapist-client interaction dynamics and potentially inform clinical supervision. We investigated synchronized bodily movement in two therapeutic relationships involving the same client: one with a key worker and one with a process supporter, whose roles imply distinct therapeutic behaviors. We examined whether nonverbal synchrony emerged over time, differed between the two therapeutic relationships, and showed leading-following patterns. Greater synchrony was expected in the process supporter-client relationship and more leading behavior in the key worker-client relationship. A single-case design was used. The client engaged in separate care-as-usual therapeutic sessions with each therapist. Bodily movement was extracted from video recordings using MEA, and CRQA assessed nonverbal synchrony and temporal coordination. Surrogate analyses indicated that the observed synchrony exceeded levels expected from chance temporal associations. Synchrony was also greater in the process supporter-client relationship than in the key worker-client relationship. No consistent leading or following behavior was observed. These findings illustrate the potential of nonlinear methods to capture dynamic relational processes in naturalistic therapeutic interactions and suggest that movement-based measures may provide clinically relevant information to complement clinical observation and support supervision. Future research should examine how movement patterns relate to therapeutic processes and outcomes, and whether movement-based feedback can improve clinical practice.","PeriodicalId":46218,"journal":{"name":"Nonlinear Dynamics Psychology and Life Sciences","volume":"30 4","pages":"459-483"},"PeriodicalIF":1.1,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149168256","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the field of Economics, which has long been tied to the concept of rational agent, these models offer the possibility of disciplining behavioral analysis, given their immense capacity to process data quickly and efficiently, thus producing coherent, well-founded, and statistically robust behavioral rules. In this context, one may expect economic theory to undergo a major transformation in the near future, as the concept of Homo-Economicus begins to be challenged by a new idea, namely that of Homo-Silicus (i.e., the generative economic agent forged with the support of LLM algorithms). The latter will not be a single or homogeneous being like the former; on the contrary, it will be a much more complex, multifaceted, and diverse entity. To illustrate the potential of the new paradigm, this article uses an LLM to assist in assembling a classification of economic agents based on the definition of different personality traits. The exercise allows for the characterization of thirty-two distinct agent types, with their economic behavior diverging according to three dimensions: economic conservatism, social orientation, and propensity for risk and innovation. A simple macroeconomic model capable of accommodating the different behavioral profiles is outlined, revealing that long-term aggregate outcomes depend on which personality types are dominant in the economy. The interaction among heterogeneous agents gives rise to complex macro patterns of behavior, with aggregate variables potentially evolving along irregular and unpredictable pathways.","PeriodicalId":46218,"journal":{"name":"Nonlinear Dynamics Psychology and Life Sciences","volume":"30 4","pages":"485-511"},"PeriodicalIF":1.1,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149171409","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The predator populations migrate between two areas. The model incorporates a Crowley-Martin response and a time delay. This study reveals several novel dynamical behaviors of populations, with and without time delay. The existence of extinction and coexistence equilibrium points is investigated using a linearization approach and the Routh-Hurwitz criteria to determine the stability. This study explores the impact of time delay by identifying the delay margin at which the time delay destabilizes the equilibrium point. Under appropriate parameter values, a stable interior equilibrium point occurs when there is no time delay. When a time delay is incorporated, certain conditions indicate that the time delay does not affect the stability of the equilibrium point. Under different parameters, the presence of a delay margin can induce harmonic oscillations and trigger a Hopf bifurcation. The results demonstrate that time delay may either preserve or alter the stability of the equilibrium point. In some cases, the presence of the time delay may even lead to population extinction over a prolonged period. Numerical simulations are provided to illustrate the population dynamics under scenarios with and without time delay.","PeriodicalId":46218,"journal":{"name":"Nonlinear Dynamics Psychology and Life Sciences","volume":"30 4","pages":"409-433"},"PeriodicalIF":1.1,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149167978","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Participants encounter four Markov-chain markets, each of which moves among three states. Across forty rounds, before investing in one market, they may purchase, at a fixed cost, a forecast of any market's next state. The markets share the same stationary distribution but differ in conditional entropy, making temporal predictability â how much today's state reveals about tomorrow's â measurable, priceable, allocable, and disruptable. The design integrates five literatures: Shannon information theory, Maxwell's demon and the thermodynamics of information, rational inattention, ergodic economics, and nonlinear-dynamical approaches to structural change. Its contribution lies in operationalising these perspectives within a single experimental task. At the midpoint, a hidden shock rotates all transition structures, reversing their entropy ranking. The task is implemented under additive and multiplicative payoff regimes, which differ in ergodic properties. Monte Carlo simulations benchmark four agent types, while an exploratory pilot indicates theoretically coherent behavioural variation.

{"title":"A Matrix Formalism for Competing Affiliations.","authors":"Thomas Wieder","doi":"","DOIUrl":"","url":null,"abstract":"We develop a compact matrix formalism for competition between two social affiliations for adherents in a well-mixed population. The share dynamics is represented by a one-dimensional replicator equation driven by a two-by-two interaction matrix, whose qualitative regimeâdominance of either affiliation, stable coexistence, or bistabilityâis fully characterized by two scalar parameters derived from the matrix entries. The central contribution is an explicit regime-switch analysis of a rank-one matrix alteration step. We show that this alteration acts on the regime parameters solely through a single control quantity determined by the desired minus current fitness difference and the current population state. Threshold conditions identify which fitness targets induce a qualitative change of the replicator flow, and a recovery condition quantifies the minimal alteration required to drive an otherwise losing affiliation to full dominance. A persistent hard core of loyal adherents plays a dual role. First, it prevents complete extinction of the disadvantaged affiliation. Second, in the reduced fluid-population model introduced here, it lowers the intervention required for recovery under matrix alteration. The interplay between hard-core size and alteration strength is made explicit: A larger hard core reduces the intervention required for recovery, and vice versa. The framework is illustrated in three stages of increasing complexity and connects to sociophysical models of opinion dynamics, language competition, and religious affiliation.","PeriodicalId":46218,"journal":{"name":"Nonlinear Dynamics Psychology and Life Sciences","volume":"30 3","pages":"353-369"},"PeriodicalIF":1.1,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148498237","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To resolve this limitation, a generative nonlinear dynamical systems framework is developed wherein desire is formalized as a vector field defined by two macroscopic order parameters: motivational intensity and semantic orientation. A coupled system of stochastic differential equations models how religious practices manipulate control parameters, specifically systemic gain and landscape curvature. Numerical simulations utilizing Euler-Maruyama integration reveal that these parameter adjustments induce critical bifurcations between two distinct topological regimes. The first, characteristic of monotheistic strategies, generates a stable fixed point exhibiting cusp-like hysteresis, which protects belief systems against environmental noise. The second, characteristic of Daoist strategies, generates a metastable regime of flexible wandering, maximizing cognitive adaptability. These findings suggest that religious traditions function as dynamic control mechanisms for managing the stability-plasticity dilemma. Ultimately, the model bridges abstract phenomenology with empirical psychology, providing testable blueprints based on the cusp catastrophe model to evaluate sudden phase transitions and cognitive hysteresis in motivational regulation.","PeriodicalId":46218,"journal":{"name":"Nonlinear Dynamics Psychology and Life Sciences","volume":"30 3","pages":"327-351"},"PeriodicalIF":1.1,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148498266","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using daily cumulative case counts from all 50 states and the District of Columbia, we fit quintic polynomials and swallowtail catastrophe models to ln-transformed data. The swallowtail model captures abrupt transitions, wave phenomena, and healthcare workload effects often missed by conventional SIR and SEIR approaches. Polynomial fits were excellent overall, with significantly better performance in Republican states, suggesting deeper differences in epidemic regularity or reporting. The swallowtail model maintained high accuracy across most states' cumulative case trajectories, indicating strong generalizability across heterogeneous epidemic wave shapes and reporting practices. Additionally, by correlating nurse shortages and physician rates with model coefficients, we found that workforce sufficiency substantially shapes key nonlinear epidemic features, highlighting healthcare capacity as a critical control variable in pandemic response strategies. Overall, this research demonstrates the adaptability of catastrophe modeling for epidemic time series and emphasizes the value of integrating nonlinear dynamics methods with detailed, interdisciplinary data sources to better describe and interpret pandemic evolution across U.S. states.","PeriodicalId":46218,"journal":{"name":"Nonlinear Dynamics Psychology and Life Sciences","volume":"30 3","pages":"299-326"},"PeriodicalIF":1.1,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148498264","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"State Space Theory as a Unifying Framework for Consciousness.","authors":"Vikas N O'Reilly-Shah","doi":"","DOIUrl":"","url":null,"abstract":"Consciousness science has generated diverse theoretical frameworks, each offering insights into different aspects of conscious experience. However, this diversity has created a fractured landscape: theories operate at different explanatory levels, and a principled account of how conscious phenomena arise from specific neural computations remains largely absent. This work argues that State Space Theory (SST) can serve as a unifying mechanistic framework for consciousness science. SST proposes that consciousness arises from hierarchical delay coordinate embedding (DCE) - the reconstruction of dynamical system structure from time-delayed signals - implemented through recurrent cortical circuits ('DCE engines'), with gain modulation determining which reconstructions achieve system-wide influence. SST identifies these dynamics with consciousness itself, not merely as correlates. We draw on recent empirical and theoretical work to demonstrate the feasibility of this proposal, including empirical demonstrations that recurrent networks learn via embedding and mathematical results linking recurrent dynamics to embedding theory. We identify how major cognitive theories map onto this architecture mechanistically: parallel DCE engines correspond to Dennett's competing \"drafts,\" global broadcasting reflects gain-amplified propagation, recurrent processing enables the temporal integration DCE requires, and the attention schema emerges as a higher-order reconstruction of gain modulation dynamics. SST's fundamentally process-based character provides immunity to the unfolding argument and resolves the temporal paradox facing causal structure theories. The framework generates a number of falsifiable predictions related to topological structure of perceptual dynamics, temporal vulnerability windows, and selective disruption of recurrent timing. SST thus offers a computational foundation for consciousness research that grounds existing theories mechanistically while generating empirical commitments.","PeriodicalId":46218,"journal":{"name":"Nonlinear Dynamics Psychology and Life Sciences","volume":"30 2","pages":"185-226"},"PeriodicalIF":0.7,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147582781","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
