Abstract

Language change is considered as a transition of population among languages. The language dynamics equation represents such a transition of population. Our purpose in this paper is to develop a new formalism of language dynamics for a real situation of language contact. We assume a situation that memoryless learners are exposed to a number of languages. We show experimental results, in which contact with other language speakers during acquisition period deteriorates the learning accuracy and prevents the emergence of a dominant language. If we suppose a communicative language, when learners are frequently exposed to a variety of languages, the language earns relatively higher rate of population. We discuss the communicative language from the viewpoint of the language bioprogram hypothesis.
