To what extent is conceptualization based on linguistic representation? And to what extent is it variable across cultures, communities or even individuals? Of crucial importance in the attempt to develop a comprehensive theory of human cognition, these remain amongst the most difficult of questions in the cognitive sciences. This volume brings together ten new contributions from leading scholars working in a wide cross-section of disciplines, including linguistics, anthropology, psychology and philosophy, with an introduction by the editors which surveys current work in the field. It is one of the first attempts to tackle explicitly the issue of the relationship between linguistic and conceptual representation from a truly interdisciplinary perspective.
