The Cultural Evolution of Human Communication Systems in Different Sized Populations: Usability Trumps Learnability

Fay, Nicolas; Ellison, Timothy

Description

This study examines the intergenerational transfer of human communication systems. It tests if human communication systems evolve to be easy to learn or easy to use (or both), and how population size affects learnability and usability. Using an experimental-semiotic task, we find that human communication systems evolve to be easier to use (production efficiency and reproduction fidelity), but harder to learn (identification accuracy) for a second generation of naïve participants. Thus,...[Show more]
