This book brings together work on the emergence of communication language drawing on diverse disciplines, including linguistics, psychology, neuroscience, anthropology and computer science. Computational simulations of the emergence of phenomena associated with communication and language play a key role in illuminating some of the most significant issues, and the renewed scientific interest in language emergence has benefited greatly from research in Artificial Intelligence and Cognitive Science. Starting with a road map chapter pointing to the ways in which disparate disciplines can inform stimulate each other, this book examines the role of simulations as a novel way to express theories in science, and their contribution to the development of a new approach to the study of the emergence of communication and language. Worldwide contributors report on the results at the forefront of this interdisciplinary field and deliver state-of-the-art research and essential reading for researchers and graduates.
