Abstract

Creole is a new born language emerging in most cases where language contact takes place. Simulating behaviors that creole communities are formed in some environments, we could contribute to actual proof of some linguistic theories concerning language acquisition. Thus far, a simulation study of the emergence of creoles has been reported in the mathematical framework. In this paper we introduce a spatial structure to the framework. We show that local creole communities are organized, and creolization may occur when language learners learn often from non-parental language speakers, in contrast to the non-spatial model. The quantitative analysis of the result tells us that emergence of local colonies at the early stage tends to induce the full creolization.
