C. elegans is a commonly studied model organism based on ease of maintenance and simple neurological structure. In contrast to traditional microscopic techniques, which require constraining motion to a 2D microscope slide, dynamic diffraction allows the observation of locomotion in 3D as a time series of the intensity at a single point in the diffraction pattern. The electric field at any point in the far-field diffraction pattern is the result of a superposition of the electric fields bending around the worm. As a result, key features of the motion can be recovered by analyzing the intensity time series. One can now apply modern nonlinear techniques; embedding and recurrence plots, providing valuable insight for visualizing and comparing data sets. We found significant markers of low-dimensional chaos. Next, we implemented a minimal biomimetic simulation of the central pattern generator of C. elegans with FitzHugh-Nagumo neurons, which exhibits undulatory oscillations similar to those of the real C. elegans. Finally, we briefly describe the construction of a biomimetic version of the Izquierdo and Beer robotic worm using Keener's implementation of the Nagumo et al. circuit.","PeriodicalId":46218,"journal":{"name":"Nonlinear Dynamics Psychology and Life Sciences","volume":"26 1","pages":"21-43"},"PeriodicalIF":0.9,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39865990","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":"Relational Fractal Dimension: From the Complexity of Psychological Interview to the Emergence of the Therapeutic Relationship.","authors":"Jacopo Biraschi","doi":"","DOIUrl":"","url":null,"abstract":"The psychological interview is a complex system which emerges from the interaction of its components, i.e., the patient and the psychologist; therefore, it is presumed to display a fractal structure whose dimension defines its level of complexity. This paper presents a pilot study for a new evaluative methodology of the fractal dimension in the psychological interview: the analysis of 4 psychological interviews led to the determination of their fractal dimension, defined by the amount of verbal content produced. The conversational turn-taking naturally established in the patient-psychologist dyad divides the verbatim transcripts of the sessions into Relational Verbal Units (RVU), whose sizes are determined by the number of words which composes them. It was observed that the distribution of the RVUs in a size/frequency graph follows a power law distribution, from which it was possible to assess the Relational Fractal Dimension (RFD) of the interviews. The values obtained range from a minimum of 1.39 to a maximum of 1.50, an indicative range of self-organized criticality. Recursion is the simple process behind complexity, and it defines fractal patterns; the fractal dimension of a system characterizes its level of complexity, and its application in psychotherapy describes the therapeutic relationship as a nonlinear dynamic system endowed with self-organization and self-similarity.","PeriodicalId":46218,"journal":{"name":"Nonlinear Dynamics Psychology and Life Sciences","volume":"26 1","pages":"81-104"},"PeriodicalIF":0.9,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39865992","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 chaotic structure among the analyzed variables was characterized by Lyapunov exponents that explore the chaotic dynamics of the series. Following, the effects of inflation, unemployment, economic growth and terror on party votes were analyzed by Fourier regression model. Then, the causality among the macroeconomic variables, terror and party groups was analyzed by the Granger causality method. According to our results, there is unidirectional causality from terror to all four party groups. In the context of macroeconomic variables, there is the evidence of bidirectional causality between conservative parties and inflation; unidirectional causality from inflation to center-right and center-left parties. There is no causality between nationalist parties and inflation. Furthermore, center-right and center-left parties have the evidence of no causality with unemployment while there is unidirectional causality from unemployment to conservative and nationalist parties. There is unidirectional causality from economic growth to conservative parties and bidirectional causality between center-right parties and economic growth. However, the center-left and nationalist parties are not the sources of Granger causality of economic growth, and there is no inverse Granger causality relationship between these variables. Therefore, it can be concluded that between the periods 03.1986-01.2020, there was no concern for economic growth in left-wing and nationalist-based parties in Turkey.","PeriodicalId":46218,"journal":{"name":"Nonlinear Dynamics Psychology and Life Sciences","volume":"26 1","pages":"105-121"},"PeriodicalIF":0.9,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39776696","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":"Complexity Regulation Competencies: A Naturalistic Framework.","authors":"Michael Kimmel","doi":"","DOIUrl":"","url":null,"abstract":"This article presents a framework to describe how professional experts regulate complex adaptive systems (CAS), a skill found across bio-psychological, ecological, technical, and social contexts. The regulation aim is to facilitate and constrain the self-organization of a CAS; regulators engage in dynamic decision making while the system evolves. While many naive regulators are overtaxed when they encounter nonlinear and multi-causal dynamics, less is known about how experts perform. I argue that a rich set of competencies can make expert performance distinctive. The basic sensitivities for CAS that shape the general philosophy of practice and a role identity as process facilitators provide some foundation. Turning this into an applied skill set, however, additionally requires (a) the creation of mediating interfaces with a 'target' CAS, (b) interaction skills for exploring and stimulating the CAS, (c) the use of domain knowledge about the system's nature and structure for conceptualizing its state as well as dynamics, (d) the use of analogical reasoning, categories, heuristics, and models to make 'if-then' inferences from systemic problem constellations to holistic strategies, and (e) synoptic and meta-regulative capabilities that allow supervising the mix of deployed resources relative to the demands of ongoing task. These CAS regulation tools mesh in variable ways and can mutually amplify each other, i.e. synergize. Illustrations for the framework come from two somatic therapies (aka bodywork), the Shiatsu and Feldenkrais methods, in which therapists use manual techniques as a regulatory means to help their clients.","PeriodicalId":46218,"journal":{"name":"Nonlinear Dynamics Psychology and Life Sciences","volume":"26 1","pages":"45-79"},"PeriodicalIF":0.9,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39865991","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":"Individual Rationality and Market Efficiency.","authors":"Steven Gjerstad, Jason Shachat","doi":"","DOIUrl":"","url":null,"abstract":"Smith's (1962) demonstration that prices and allocations quickly converge to the competitive equilibrium in the continuous double auction (CDA) remains one of the most important results in experimental economics. Market experiments and exchange models have added considerably to our knowledge of how markets reach equilibrium, and how they respond to disruptions. Perhaps the best-known model of exchange in CDA market experiments is the random behavior 'zero-intelligence' (ZI) model by Gode and Sunder (1993). They argue that the CDA generates efficient allocations and 'convergence of transaction prices to the proximity of the theoretical equilibrium price,' provided only that agents meet their budget constraints. We demonstrate that prices do not converge in their simulations. Their budget constraint requires that a buyer's currency never exceeds her commodity value, which is an unnatural restriction. Their conclusion that market efficiency results from the structure of the CDA independent of traders' profit seeking behavior rests on their claim that the constraints that they impose are a part of the market institution. We show that actually they impose individual rationality. Misinterpretation of this behavioral constraint has led to unproductive debate on market adjustment processes.","PeriodicalId":46218,"journal":{"name":"Nonlinear Dynamics Psychology and Life Sciences","volume":"25 4","pages":"395-406"},"PeriodicalIF":0.9,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39413304","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}
