"This book contains the results of my studies in the intelligence of Apes at the Anthropoid Station in Tenerife from the years 1913-1917. The original, which appeared in 1917, has been out of print for some time. I have taken this opportunity of making a few changes in the critical and explanatory sections, and have added as an Appendix some general considerations on the Psychology of Chimpanzees. With various recent books and essays on the subject I shall have an opportunity of dealing in a further contribution to the subject not yet completed"--Preface.

Wolfgang Koehler demonstrated that chimpanzees could solve problems by applying insight. His research showed that the intellectual gap between humans and chimpanzees was much narrower than previously thought. The work was revolutionary when originally published in 1917 in German, but it was largely ignored for decades because it violated the conventional wisdom that animal behavior is simply the result of instinct or conditioning. However, Koehler's research showed this was not the case. He used four chimps in his experiments, Chica, Grande, Konsul, and Sultan. The experiments consisted of placing chimpanzees in an enclosed area and presenting them with a desired object that was out of reach. In one experiment, Koehler placed bananas outside Sultan's cage and two bamboo sticks inside his cage which needed to be put together to reach the bananas. Koehler demonstrated the solution to Sultan by putting his fingers into the end of one of the sticks. After some contemplation, Sultan put the two sticks together and was able to reach the bananas. As Jaan Valsiner shows in his introduction to this classic work, Koehler's analysis of the intelligence of apes marked a turning point in the psychology of thinking and the continuing struggle between behaviorism and cognitive psychology. Koehler achieved his two-fold aim: to determine the relationship between the intellectual capacity of higher primates and man, and to gain insight into the nature of intelligent acts.

A fascinating collection of writing by some of the finest minds the world has ever known. A must read fro anybody with an interest in the history of psychology, with writings by the Aristotle, Galileo, Descartes, Newton, Von Helmholtz, Thorndike and much more. Many of the earliest books, particularly those dating back to the 1900s and before, are now extremely scarce and increasingly expensive. We are republishing these classic works in affordable, high quality, modern editions, using the original text and artwork.

Annotation As Jane Goodall never fails to mention, "bush meat is the greatest conservation crisis in my lifetime." This book documents in text and photographs how wild animals in the Congo Basin, particularly the Great Apes but also chimpanzees, bonobos, and gorillas, are slaughtered and used for human consumption.

Current primate research has yielded stunning results that not only threaten our underlying assumptions about the cognitive and communicative abilities of nonhuman primates, but also bring into question what it means to be human. At the forefront of this research, Sue Savage-Rumbaugh recently has achieved a scientific breakthrough of impressive proportions. Her work with Kanzi, a laboratory-reared bonobo, has led to Kanzi's acquisition of linguistic and cognitive skills similar to those of a two and a half year-old human child. Apes, Language, and the Human Mind skillfully combines a fascinating narrative of the Kanzi research with incisive critical analysis of the research's broader linguistic, psychological, and anthropological implications. The first part of the book provides a detailed, personal account of Kanzi's infancy, youth, and upbringing, while the second part addresses the theoretical, conceptual, and methodological issues raised by the Kanzi research. The authors discuss the challenge to the foundations of modern cognitive science presented by the Kanzi research; the methods by which we represent and evaluate the abilities of both primates and humans; and the implications which ape language research has for the study of the evolution of human language. Sure to be controversial, this exciting new volume offers a radical revision of the sciences of language and mind, and will be important reading for all those working in the fields of primatology, anthropology, linguistics, philosophy of mind, and cognitive and developmental psychology.

This edition presents the first complete English translation of N.N. Ladygina-Kohts' journal chronicling her pioneering work with the chimpanzee, Joni. The journal entries describe and compare the instincts, emotions, play, and habits of her son Rudy and Joni as each develops. First published in Moscow in 1935 as a memoir in the Darwin Museum Series, this edition has 120 photographs, 46 drawings and an introduction by Allen and Beatrix Gardner of the Center for Advanced Study at the University of Nevada, as well as a Foreword and an Afterword by Lisa A. Parr, Signe Preuschoft, and Frans B. M. de Waal of the Living Links Center at Emory University.
