This study introduces a new model for vocabulary evolution using evolutionary game dynamics. It highlights active, peer-to-peer learning for cultural vocabulary acquisition.

Area of Science:

  • Computational Linguistics
  • Evolutionary Game Theory
  • Cultural Evolution

Background:

  • Evolutionary game dynamics offer a mathematical framework for understanding cultural evolution, particularly vocabulary development.
  • Previous models often focused on passive learning or vertical transmission, limiting their scope.
  • A need exists for models that capture active, peer-to-peer cultural learning mechanisms.

Purpose of the Study:

  • To present a novel model for vocabulary evolution based on active, peer-to-peer social learning.
  • To contrast this model with previously suggested, mutually exclusive frameworks.
  • To formalize the cultural transmission mechanism using learning theory and evolutionary dynamics.

Main Methods:

  • Abstracting the 'naming game' concept from learning theory to define a cultural transmission mechanism.

  • Expressing the transmission system using the established selection-mutation model from evolutionary dynamics.
  • Focusing on horizontal and oblique transmission structures, with potential for vertical extensions.
  • Main Results:

    • The model demonstrates how active participation and peer-to-peer communication drive vocabulary acquisition.
    • An explicit analogy is established between social learning processes and evolutionary dynamics at the meaning-word association level.
    • Simplified experiments illustrate the model's reasoning and applicability.

    Conclusions:

    • The proposed model offers a distinct perspective on vocabulary evolution, emphasizing active and horizontal cultural transmission.
    • This framework provides a robust mathematical approach to understanding the dynamics of word-meaning associations.
    • The model is adaptable for incorporating vertical transmission structures in future research.
