Dr. Roland Mühlenbernd ist wissenschaftlicher Mitarbeiter im DFG-Projekt A05 Die Modellierung von semantischen Registerunterschieden im Rahmen des SFB 1412 Register: Language-Users’ Knowledge of Situational-Functional Variation / Forschungsbereich 4 ‚Semantik & Pragmatik‘.

Er interessiert sich vor allem für die Frage, wie sich individuelles Verhalten auf soziale Konventionen und Normen auswirkt. In Bezug auf menschliche Sprache möchte er diesbezüglich Erkenntnisse darüber erlangen, warum Sprecher und Hörer bestimmte Entscheidungen in Sprachproduktion und Perzeption treffen, und wie sich diese Entscheidungen langfristig auf das Sprachsystem auswirken. Zu diesem Zweck entwickelt er (insbesondere spieltheoretische) Kommunikationsmodelle und untersucht diese (i) anhand von Lösungskonzepten der (evolutionären) Spieltheorie, (ii) durch computergestützte Ansätze, und (iii) durch Experimente mit künstlichen Kommunikationssystemen. Er interessiert sich insbesondere für Fragestellungen innerhalb der linguistischen Forschungsbereiche Sprachwandel/Sprachevolution und Semantik/Pragmatik.

    We study an extended version of a sender–receiver signaling game—a context-signaling (CS) game that involves external contextual cues that provide information about a sender’s private information state. A formal evolutionary analysis of the investigated CS game shows that ambiguous signaling strategies can achieve perfect information transfer and are evolutionarily stable. Moreover, a computational analysis of the CS game shows that such perfect ambiguous systems have the same emergence probability as non-ambiguous perfect signaling systems in multi-agent simulations under standard evolutionary dynamics. We contrast these results with an experimental study where pairs of participants play the CS game for multiple rounds with each other in the lab to develop a communication system. This comparison shows that unlike virtual agents, human agents clearly prefer perfect signaling systems over perfect ambiguous systems.
  • Mühlenbernd, Roland; Solt, Stephanie  (2022) Modeling (im)precision in context  In: Linguistics Vanguard [DOI] [PDF] [ViVo]
    Abstract Speakers’ choice between linguistic alternatives often depends on the situation, a prime example involving level of precision at which numerical information is communicated. We report on a production study in which participants report the time of an event in two different situations, and demonstrate that the results can be reproduced by a probabilistic game-theoretical model in which the speaker’s choice reflects a tradeoff between informativity, accuracy and hearer-oriented simplification. These findings shed light on the pragmatics of (im)precision, and the dynamics of situationally driven pragmatic variation more generally.
  • Mühlenbernd, Roland; Wacewicz, Slawomir; Zywiczyński, Przemyslaw  (2021) Politeness and reputation in cultural evolution  In: Linguistics and Philosophy [DOI] [PDF] [ViVo]
    Politeness in conversation is a fascinating aspect of human interaction that directly interfaces language use and human social behavior more generally. We show how game theory, as a higher-order theory of behavior, can provide the tools to understand and model polite behavior. The recently proposed responsibility exchange theory (Chaudhry and Loewenstein in Psychol Rev 126(3):313–344, 2019) describes how the polite communications of thanking and apologizing impact two different types of an agent’s social image: (perceived) warmth and (perceived) competence. Here, we extend this approach in several ways, most importantly by adding a cultural-evolutionary dynamics that makes it possible to investigate the evolutionary stability of politeness strategies. Our analysis shows that in a society of agents who value status-related traits (such as competence) over reciprocity-related traits (such as warmth), both the less and the more polite strategies are maintained in cycles of cultural-evolutionary change.
