Animal Intelligence

Leading research workers have contributed to this volume of papers of broad interest, which reflects the recent convergence of different approaches to the subject, using newly developed techniques. Research on sign language in chimpanzees has raised many fundamental and controversial issues on the nature of language and thought in animals, while ethologists and experimental psychologists have also made observations about animal communication and cognitive skills. Some of these developments have also appeared independently, in the context of dissociable capacities from studies of brain function in man, and the nature of brain development in evolution and animal intelligence is one of continuing enquiry. This book brings together the various approaches from both field and laboratory, and highlights some still controversial issues.
