This book is a themed, mutually referenced collection of articles based on the workshop on “Current developments in non-human primate gesture research”, which was held in July 2010 at the European University Viadrina, Frankfurt (Oder), Germany. The motivation for this book – following on from the motivation for the workshop series – was to present the state of the art in non-human primate gesture research with a special emphasis on its history, interdisciplinary perspectives, developments and future directions. This book provides, for the first time in a single volume, the most recent work on comparative gestural signaling by many of the major scholars in the field, such as W.D. Hopkins, D. Leavens, T. Racine, J. van Hooff, and S. Wilcox (in alphabetical order).
