Compositional syntax emerges from iterated observational learning, not just innate language acquisition devices. Sparse language exposure drives the evolution of structured communication systems.

Area of Science:

  • Evolutionary Linguistics
  • Computational Linguistics
  • Cognitive Science

Background:

  • Syntactic structure evolution is observed in genetically identical agents.
  • Traditional explanations rely on innate language acquisition devices (LAD) and genetic coding.
  • The 'poverty of the stimulus' highlights the gap between complex language and sparse input.

Purpose of the Study:

  • To investigate the emergence of compositional syntax through cultural evolution.
  • To explore how sparse language exposure influences syntactic structure development.
  • To challenge the sole reliance on innate mechanisms for explaining language structure.

Main Methods:

  • Development of a mathematical model to simulate language evolution.
  • Analysis of iterated observational learning dynamics.

  • Mapping parameter spaces leading to compositional syntax.

    • Main Results:

    • The 'poverty of the stimulus' creates pressure for compositional language structure.
    • Compositional syntax emerges as a property of learning dynamics, not solely innate factors.
    • Iterated observational learning drives the evolution of structured communication.

    Conclusions:

    • Compositional syntax is an emergent property arising from sparse language exposure and learning dynamics.
    • Cultural evolution, through observational learning, plays a crucial role in shaping language structure.
    • Explanations for language structure must consider both innate predispositions and environmental influences.
