Towards a Model of the Interplay of Mentalizing and Mirroring in Embodied Communication

Abstract The social brain contains distinct networks for mentalizing as well as for mirroring-based action observation. We present work towards a model of how these two systems may interact during embodied communication. The model connects a mentalizing system for attributing and inferring different orders of belief about own and other's mental states, with a hierarchical predictive model for online action perception and production. We discuss interactions between both systems and describe simulation experiments in which two agents equipped with this model engage in embodied communication. Results demonstrate how mentalizing affords higher robustness of communication by enabling interactive grounding processes

A Predictive Processing Model of Perception and Action for Self-Other Distinction

Kahl S, Kopp S. A Predictive Processing Model of Perception and Action for Self-Other Distinction. Frontiers in Psychology. 2018;9: 2421.During interaction with others, we perceive and produce social actions in close temporal distance or even simultaneously. It has been argued that the motor system is involved in perception and action, playing a fundamental role in the handling of actions produced by oneself and by others. But how does it distinguish in this processing between self and other, thus contributing to self-other distinction? In this paper we propose a hierarchical model of sensorimotor coordination based on principles of perception-action coupling and predictive processing in which self-other distinction arises during action and perception. For this we draw on mechanisms assumed for the integration of cues for a sense of agency, i.e., the sense that an action is self-generated. We report results from simulations of different scenarios, showing that the model is not only able to minimize free energy during perception and action, but also showing that the model can correctly attribute sense of agency to own actions

How is information distributed across speech and gesture? A cognitive modeling approach

Bergmann K, Kahl S, Kopp S. How is information distributed across speech and gesture? A cognitive modeling approach. Cognitive Processing. 2014;15(1: Special Issue: Proceedings of KogWis 2014):S84-S87.In naturally occurring speech and gesture, meaning occurs organized and distributed across the modalities in different ways. The underlying cognitive processes are largely unexplored. We propose a model based on activation spreading within dynamically shaped multimodal memories, in which coordination arises from the interplay of visuo-spatial and linguistically shaped representations under given cognitive resources. A sketch of this model is presented together with simulation results

Self-sufficient sensor for oxygen detection in packaging via radio-frequency identification

A new disposable radio-frequency identification (RFID) sensor for detecting oxygen in packages with a protective atmosphere is presented. For safety reasons and system costs in consumer packages, no battery or energy harvesting devices can be used. Each part of a package, especially in food packaging, must be completely safe even if it is swallowed. Several materials have been investigated that safely react with oxygen and thus change electrical parameters without the need of an additional energy supply. In particular linseed oil was tested, because it is known to react in oxygen-containing atmosphere from liquid to solid. Linseed oil is used not only as food but also as a key part in ecological paint coatings. A significant relative change of capacity was observed during linseed oil drying, which results in −20% after 5 h and −38% after 30 h at an oxygen concentration of 20.5 and 50% relative humidity, respectively. Pure unsaturated fatty acids were also tested in an oxygen-containing atmosphere and showed similar behaviour. The reaction speed is partially dependent on the level of unsaturation of fatty acids. The oxygen sensor is coupled with an RFID front end with an internal charge time measurement unit for capacity determination. The combination of sensor element, sensitive material and RFID allows for biocompatible and save systems that indicate the presence of oxygen within a package
