Evolution of Communicative Flexibility

This chapter uses a self-organizing map approach to simulate learning of the human vocal system through babbling, and deals with the constraints and mechanisms at work in the development and evolution of phonetic repertoires to establish a stable system of discrete speech sounds that can form the basis of a flexile communicative system. It shows that the principle of mutually constraining topographic maps provides possible explanations of phenomena in areas as diverse as speech processing, word learning, categorization, and language evolution. The chapter suggests that the mirror neurons are one piece of evidence of the correlation-based integration of neural populations across domains.

Keywords:   vocal system, babbling, speech sounds, flexile communicative system, topographic maps, speech processing, word learning, categorization, language evolution, mirror neurons
