?Intelligence of Apes and Other Rational Beings is the best single source where one can find out what apes and monkeys know and how we know it. It is also an entertaining, highly informative candid history of studies of anthropoid learning and cognition, which points the way toward future discoveries.??Russ Tuttle, Professor of Anthropology and Evolutionary Biology, The University of Chicago

?In this remarkable book, Duane Rumbaugh and David Washburn illuminate the questions of primate intelligence with style, with savvy, and with compassion. This is an intensely provocative?and readable?journey through an important subject.??Deborah Blum, author of Love at Goon Park: Harry Harlow and the Science of Affection

?An important contribution to our understanding of the evolution and development of intelligence and cognition.??Gary Greenberg, Wichita State University

"An important, original book that presents a body of primate learning and a perspective that has heretofore not received the attention that it deserves.??James King, University of Arizona

"This book summarizes decades of research on ape behavior, and it?s a mindblower."?National Geographic Adventure

"Earnestly written in a clear style, [this] book will most likely appeal to academics and students of animal behavior. . . . For those with an interest in primate intelligence and some scientific background, this passionately argued and well-substantiated summation judiciously renders the complexities of the animal mind."?Publishers Weekly

?The book is worth the attention of anyone interested in animal learning and behavior. Its interdisciplinary nature links studies in ethology, neurophysiology, behavior, and cognition through the overarching principle of rational behaviorism. . . . Rumbaugh and Washburn?s theory increases the sophistication of our understanding of complex behaviors and affords animals a more esteemed position in our world. Intelligence of Apes and Other Rational Beings provides a window into the ways that animals are creative.??Francine Dolins, Science

?This is a noteworthy, admirable attempt to synthesize the literature on primate intelligence. In doing so, it succeeds all the more in detailing the impressive career of one of the most important ape cognition researchers of the past 40 years.??Craig Stanford, The Quarterly Review of Biology

?Intelligence, creativity and complex learning in non-human animals have concerned psychologists and others throughout the history of psychology and the evolutionary sciences. . . . Rumbaugh and Washburn have addressed these issues by amassing data from animal research and developing concepts that can be useful in understanding intelligent behavior in both non-human animals and human beings.??H. Carl Haywood, American Psychological Society
