Abstract. The naming game is a formal mechanism that describes the development of a lexicon in a society of culturally interacting agents. We will here use a cellular automaton version of this game to study the influence of an extra­linguistic structure over the evolution of the lexicon, but also the influence of language over this a priori structure. This extra­linguistic structure will be coded by first giving a location in a 2­D world to agents, and then by allowing them to move in relation to the outcome of the naming games. The results we will present show strong self­organization phenomena, such as the appearance of language and geographical clusters, in addition to the basic properties of the game (high communication success).
1 Introduction Language as a complex dynamical system has been increasingly studied in the last decade. Formal models have been built to investigate the question of the emergence of language through self­organisation in a society of culturally inter­ acting agents. This work is practically done both in simulations and by using robotic agents ([3]). One of the questions raised is : how can a lexicon shared by many agents emerge ? How can initially random form­meaning associations self­ organize through cultural evolution ? The naming game is a formal mechanism that has thus been introduced to tackle this question ([7]), and will be described in section 2. Many results have already been worked out, in particular by cou­ pling it with other language games ([5]). Yet, most of them concentrated on the language itself and did not consider the possibility of having a priori extra­ linguistic structure in the agent society. The first step was done in [4] where the idea of ...
