FIELD STUDIESStudies of Pidgins and Creoles, Nicaraguan sign language, Home-sign-languages
Language games with artificial agentsCOMPUTER SIMULATIONS
BUT… WE DON’T HAVE EXPERIMENTAL CONTROL…
BUT… HUMANS ARE MUCH MORE COMPLEX THAN ARTIFICIAL AGENTS…
Combining the two options: field simulationsPut two (or more) humans into a virtual environment that requires
them to coordinate their individual actions and… neutralize the use of pre-established communication systems (e.g., speech, writing, body language…)
Field simulations: a new option for studying the emergence of human
communication systems

Studying communication systems in the laboratoryHow field simulations can help
When studying a complex system, we can never know in advance what is going to relate to what
