(2018) : Self-integrating Organic Control Systems: from Crayfish to Smart Homes In: ARCS: ARCS Workshop 2018; 31th International Conference on Architecture of Computing Systems: Berlin, Germany: Axel Springer SE, S. 1-8. Online verfügbar unter ARCS Workshop 2018; 31th International Conference on Architecture of Computing Systems
Abstract: Survival in complex environments, for both natural and artificial systems, requires behavioural adaptation to common changes and behavioural innovation to face the unexpected. The challenge here is to produce a vast variety of behaviours, each adapted to current circumstances, while relying on a limited amount of resources (e.g. sensors, controllers and actuators), within a 'suitable' time-frame. Drawing inspiration from neural and behavioural studies on crayfish, this position paper brings to the fore several key design features that enable organisms to address this challenge. It then proposes a similar design for artificial controllers, based on: i) an extensible set of reusable control units; and, ii) a goal-driven, context-sensitive (self-)integration process for assembling control units into a wide variety of integrated system controllers. Pre-integrated sub-controllers can also be merged, to improve efficiency while avoiding conflicts. The proposal is illustrated via a proof-of-concept implementation for the smart home, where users can add and remove goals and devices at runtime and the controller is adapted accordingly. This study brings us closer to our long-term objective of defining reusable methodologies and platforms for the development of self-* systems running in complex unpredictable environments, notably including smart homes, cities, vehicular networks and electrical grids, merged via the Internet of Things, and of People.

(2017): An Evolutionary Transfer Reinforcement Learning Framework for Multiagent Systems. In: IEEE Transactions on Evolutionary Computation 21 (4), S. 601-615. DOI: 10.1109/TEVC.2017.2664665
Abstract: In this paper, we present an evolutionary transfer reinforcement learning framework (eTL) for developing intelligent agents capable of adapting to the dynamic environment of multiagent systems (MASs). Specifically, we take inspiration from Darwin's theory of natural selection and Universal Darwinism as the principal driving forces that govern the evolutionary knowledge transfer process. The essential backbone of our proposed eTL comprises several meme-inspired evolutionary mechanisms, namely meme representation, meme expression, meme assimilation, meme internal evolution, and meme external evolution. Our proposed approach constructs social selection mechanisms that are modeled after the principles of human learning to identify appropriate interacting partners. eTL also models the intrinsic parallelism of natural evolution and errors that are introduced due to the physiological limits of the agents' ability to perceive differences, so as to generate "growth" and "variation" of knowledge that agents have of the world, thus exhibiting higher adaptivity capabilities on solving complex problems. To verify the efficacy of the proposed paradigm, comprehensive investigations of the proposed eTL against existing state-of-the-art TL methods in MAS, are conducted on the "minefield navigation tasks" platform and the "Unreal Tournament 2004" first person shooter computer game, in which homogeneous and heterogeneous learning machines are considered.

(2017): THE IMPORTANCE OF FACILITATION IN SUCCESSFUL ADAPTATION. In: Science and Education 23 (7), S. 142-146. DOI: 10.24195/2414-4665-2017-7-23
Abstract: This paper presents the data concerning the connectedness of the facilitative potential components, its manifestation in different fields of vital activity, basic senses of helping behaviour and socio-psychological adaptability. Based on the results of multiple regressive analysis, there has been established the importance of all facilitation aspects in order to predict personality adaptability. It has been proved that persons with developed facilitation have a higher degree of adaptability (on the sample of socionomic professions). The study of the peculiarities of adaptation directly in a complex life situation which is the process of accommodation to a foreign environment that can be combined with the beginning of family relations and is a rather tense and difficult period in subjects' lives has shown the importance of the facilitative ability in the success of its course. The obtained data provide valuable information on possible ways to increase the individual adaptivity through the development, formation of their facilitative potential, as well as the facilitative qualities of the social environment.

(2016): The 'Conversation Partner' Phenomenon in the Dialogical I-Other Relationship. In: SSRN Electronic Journal. DOI: 10.2139/ssrn.2884743
DOI: https://doi.org/10.2139/ssrn.2884743 Abstract: Authors develop a new approach to the study of one's relationships with others, which focuses on the conditions and the effects of the dialogical nature of a person. Theoretical modeling, hermeneutics, qualitative and quantitative methods have been applied. The solution for identifying prerequisites of self-development and social positioning of a person that are rooted in dialogical I-Other relationships has been suggested. The originality of the paper is associated with describing the relation to the other as a reflexive I-Other relationship; with an elaborated model that highlights the variety of dimensions of I-Other relationships (between I and Other, I-in-Other, Other-in-Me, I-in-Myself) results in a truly dialogical mode of being; with revealing the potentials of a Conversation Partner in dialogical I-Other relationships (subjective interrelations and significance of Conversation Partners, their activity, fullness of the reflection of significant Conversation Partners); with a description of different hypostases of Conversation Partners (Real, Ideal, Secret, I as Myself) by the means of hermeneutics. The method called "My Conversation Partner" should also be mentioned, as well as the empirical study of existential and social resources of Conversation Partners. Theoretical background of the study was formed by the works of M.M. Bakhtin, M. Buber, M. Heidegger, J.-P. Sartre. E. Levinas, as well as by the works of modern psychologists such as G.M. Kuchinsky, A.V. Rossokhin, E.B. Starovoytenko, C.T. Brown & P.W. Keller, Hubert Hermans, F. Rivetti Barbo, etc. Results of the current research have shown that the potential of social adaptivity, affiliation, dominance, positive solitude, joy of solitude, freedom, self-transcendence, existential fulfillment is associated with the richness of one's Conversation Partners.

(2016): A context-aware approach in realization of socially intelligent industrial robots. In: Robotics and Computer-Integrated Manufacturing 37, S. 79-89. DOI: 10.1016/j.rcim.2015.07.002
Abstract: Contemporary industrial environments are usually constrained or limited in order to fit a fast, cheap and non-error prone production. Human-like system capabilities are not generally desirable there. But, recent trends in industrial robotics demand robust, flexible and efficient robots with a certain level of autonomy. Therefore, new and different approaches and perspectives in designing of industrial facilities are required. This paper reveals how a context-based reasoning can be used to achieve an intelligent robot group behavior. In order to achieve adaptivity, self-recovery or scalability of the system, a COgnitive MOdel for the Robot group control (COMOR) is developed. COMOR can be understood as an interpreter used to transform high-level context to low-level data, allowing machines to make context-based decisions. COMOR has three main parts and relies on a simulated Social Capital phenomenon as a feature of people. The first part is used to collect significant information from the environment. The second part is used to provide a set of possible solutions respecting the semantic domain description. The last part of COMOR is used to provide a behavioral component ensuring an optimal solution to given environmental conditions.

(2014): Tracking managerial conflict adaptivity. Introducing a dynamic measure of adaptive conflict management in organizations. In: Journal of Organizational Behavior 35 (7), S. 945-968. DOI: 10.1002/job.1935
Abstract: Since Darwin, adaptation to change has been associated with survival and fit. Yet, despite this, leaders and managers often get stuck in dominating approaches to conflict, and few scholars have examined the role of adaptation in managing conflicts effectively over time and across changing situations. The goal of this paper is threefold. First, we develop a new measure for assessing conflict adaptivity of managers [the Managerial Conflict Adaptivity Assessment (MCAA)], based on a situated model of conflict in social relations. We define conflict adaptivity as the capacity to respond to different conflict situations in accordance with the demands specified by the situation. The measure consists of 15 distinct work-conflict scenarios and provides five behavioral response options, which represent five primary strategies employed in conflict. Individuals who tend to respond to the conflicts in a manner consistent with the situations provided are considered to be more adaptive. Second, we test and find that managerial conflict adaptivity is related to higher levels of satisfaction with conflict processes at work as well as higher levels of well-being at work. Third, we test the MCAA's construct validity and provide evidence that the MCAA is positively related to behavioral flexibility and self-efficacy.

(2014): Perspective-taking in dialogue as self-organization under social constraints. In: New Ideas in Psychology 32, S. 131-146. DOI: 10.1016/j.newideapsych.2013.03.004
Abstract: We present a dynamical systems account of how simple social information influences perspective-taking. Our account is motivated by the notion that perspective-taking may obey common dynamic principles with perceptuomotor coupling. We turn to the prominent HKB dynamical model of motor coordination, drawing from basic principles of self-organization to describe how conversational perspective-taking unfolds in a low-dimensional attractor landscape. We begin by simulating experimental data taken from a simple instruction-following task, in which participants have different expectations about their interaction partner. By treating belief states as different values of a control parameter, we show that data generated by a basic dynamical process fits overall egocentric and other-centric response distributions, the time required for participants to enact a response on a trial-by-trial basis, and the action dynamics exhibited in individual trials. We end by discussing the theoretical significance of dynamics in dialog, arguing that high-level coordination such as perspective-taking may obey similar dynamics as perceptuomotor coordination, pointing to common principles of adaptivity and flexibility during dialog

(2013): Creating a model of the dynamics of socio-technical groups. In: User Modeling and User-Adapted Interaction 23 (4), S. 345-379. DOI: 10.1007/s11257-012-9122-3
Abstract: Individuals participating in technologically mediated forms of organization often have difficulty recognizing when groups emerge, and how the groups they take part in evolve. This paper contributes an analytical framework that improves awareness of these virtual group dynamics through analysis of electronic trace data from tasks and interactions carried out by individuals in systems not explicitly designed for context adaptivity, user modeling or user personalization. We discuss two distinct cases to which we have applied our analytical framework. These two cases provide a useful contrast of two prevalent ways for analyzing social relations starting from electronic trace data: either artifact-mediated or direct person-to-person interactions. Our case study integrates electronic trace data analysis with analysis of other, triangulating data specific to each application. We show how our techniques fit in a general model of group informatics, which can serve to construct group context, and be leveraged by future tool development aimed at augmenting context adaptivity with group context and a social dimension. We describe our methods, data management strategies and technical architecture to support the analysis of individual user task context, increased awareness of group membership, and an integrated view of social, information and coordination contexts.

(2012): Getting Down to Basics. A Situated Model of Conflict in Social Relations. In: Negotiation Journal 28 (1), S. 7-43. DOI: 10.1111/j.1571-9979.2011.00324.x
Abstract: The field of conflict resolution is fractured. Despite many decades of fine research, we still lack a basic unifying framework that integrates the many theories of conflict dynamics. Thus, the findings from research on conflict are often piecemeal, decontextualized, contradictory, or focused on negative outcomes, which contributes to a persistent research-practice gap. In this article, we describe a situated model for the study of conflict that combines separate strands of scholarship into a coherent framework for conceptualizing conflict in dyadic social relations. The model considers conflict interactions in the context of social relations and employs prior research on the fundamental dimensions of social relations to create a basic framework for investigating conflict dynamics. The resulting model is heuristic and generative. We discuss the theoretical context and main propositions of this model as well as its implications for conflict resolution practitioners.

(2012): Language as Social Coordination. An evolutionary perspective. In: Interaction Studies 13 (1), S. 103-124. DOI: 10.1075/is.13.1.07fus
Abstract: Human social coordination is often mediated by language. Through verbal dialogue, people direct each other's attention to properties of their shared environment, they discuss how to jointly solve problems, share their introspections, and distribute roles and assignments. In this article, we propose a dynamical framework for the study of the coordinative role of language. Based on a review of a number of recent experimental studies, we argue that shared symbolic patterns emerge and stabilize through a process of local reciprocal linguistic alignment. Such patterns in turn come to facilitate and refine social coordination by enabling the alignment, joint construction and navigation of conceptual models and actions. Implications of the framework are illustrated and discussed in relation to a case study where dyads of interlocutors interact verbally to reach joint decisions in a perceptual discrimination task.

(2012): Entwicklung und Validierung eines Fragebogens zur Erfassung von „Adaptive Performance“. In: Zeitschrift für Arbeits- und Organisationspsychologie A&O 56 (2), S. 55-69. DOI: 10.1026/0932-4089/a000069
Abstract: The article deals with the development and validation of a questionnaire measuring adaptive performance (AP). AP is defined as behavior in reaction to changed work situations that promote the functioning of the organization. Consistent with our hypothesis the data reveal a two-dimensional structure for supervisor appraisals as well as for self-assessments, thereby distinguishing between a task oriented and a social focus of adaptivity. Two studies provide empirical evidence that AP is separable from in-role performance and explains specific variance in global performance appraisals of supervisors. Further validations reveal positive correlations of AP and the two traits flexibility and interpersonal skills, whereas, as anticipated, flexibility is higher correlated with task oriented AP, and interpersonal skills higher with social AP.

(2008): On the design of neuro-controllers for individual and social learning behaviour in autonomous robots. An evolutionary approach. In: Connection Science 20 (2-3), S. 211-230. DOI: 10.1080/09540090802092014
Abstract: In biology/psychology, the capability of natural organisms to learn from the observation/interaction with conspecifics is referred to as social learning. Roboticists have recently developed an interest in social learning, since it might represent an effective strategy to enhance the adaptivity of a team of autonomous robots. In this study, we show that a methodological approach based on artifcial neural networks shaped by evolutionary computation techniques can be successfully employed to synthesise the individual and social learning mechanisms for robots required to learn a desired action (i.e. phototaxis or antiphototaxis).
