LEC meeting 26th February: talk by Kenny Smith
By Kenny | February 25, 2013
I will be talking about some recent modelling work I’ve been doing that suggests that “Linguistic structure is an evolutionary trade-off between simplicity and expressivity”. Tuesday 26th, 11am, DSB 1.17.
“Linguistic structure is an evolutionary trade-off between simplicity and expressivity”
Language exhibits structure: a species-unique system for expressing complex meanings using complex forms. We present a review of modelling and experimental literature on the evolution of structure which suggests that structure is a cultural adaptation in response to pressure for expressivity (arising during communication) and compressibility (arising during learning), and test this hypothesis using a new Bayesian iterated learning model. We conclude that linguistic structure can and should be explained as a consequence of cultural evolution in response to these two pressures.
