Modelling social structures and hierarchies in language evolution

Abstract

Language evolution might have preferred certain prior social configurations over others. Experiments conducted with models of different social structures (varying subgroup interactions and the presence of a dominant interlocutor) suggest that having isolated agent groups rather than an interconnected agent is more advantageous for the emergence of a social communication system. Accordingly, distinctive groups that are closely connected by communication yield systems less like natural language than fully isolated groups inhabiting the same world, while the addition of a dominant male who is asymmetrically favoured as a hearer, and equally likely to be a speaker has no positive influence on the quality of the emergent communal language. © 2011 Springer-Verlag London Limited.
