In this volume, the Gardners and their co-workers explore the continuity between human behavior and the rest of animal behavior and find no barriers to be broken, no chasms to be bridged, only unknown territory to be charted and fresh discoveries to be made. With the beginning of Project Washoe in 1966, sign language studies of chimpanzees opened up a new field of scientific inquiry by providing a new tool for looking at the nature of language and intelligence and the relation between human and nonhuman intelligence. Here, the pioneers in this field review the unique procedures that they developed and the extensive body of evidence accumulated over the years. This close look at what the chimpanzees have actually done and said under rigorous laboratory conditions is the best answer to the heated controversies that have been generated by this line of research among ethologists, psychologists, anthropologists, linguists, and philosophers.

In the 1970s, the behavioral psychologist Herbert S. Terrace led a remarkable experiment to see if a chimpanzee could be taught to use language. A young ape, named “Nim Chimpsky” in a nod to the linguist whose theories Terrace challenged, was raised by a family in New York and instructed in American Sign Language. Initially, Terrace thought that Nim could create sentences but later discovered that Nim’s teachers inadvertently cued his signing. Terrace concluded that Project Nim failed—not because Nim couldn’t create sentences but because he couldn’t even learn words. Language is a uniquely human quality, and attempting to find it in animals is wishful thinking at best. The failure of Project Nim meant we were no closer to understanding where language comes from. In this book, Terrace revisits Project Nim to offer a novel view of the origins of human language. In contrast to both Noam Chomsky and his critics, Terrace contends that words, as much as grammar, are the cornerstones of language. Retracing human evolution and developmental psychology, he shows that nonverbal interaction is the foundation of infant language acquisition, leading up to a child’s first words. By placing words and conversation before grammar, we can, for the first time, account for the evolutionary basis of language. Terrace argues that this theory explains Nim’s inability to acquire words and, more broadly, the differences between human and animal communication. Why Chimpanzees Can’t Learn Language and Only Humans Can is a masterful statement of the nature of language and what it means to be human.

NEW YORK TIMES BESTSELLER Now Elizabeth Hess’s unforgettable biography is the inspiration for Project Nim, a riveting new documentary directed by James Marsh and produced by Simon Chinn, the Oscar-winning team known for Man on Wire. Hess, a consultant on the film, says, “Getting a call from James Marsh and Simon Chinn is an author’s dream. Project Nim is nothing short of amazing.” Could an adorable chimpanzee raised from infancy by a human family bridge the gap between species—and change the way we think about the boundaries between the animal and human worlds? Here is the strange and moving account of an experiment intended to answer just those questions, and the astonishing biography of the chimp who was chosen to see it through. Dubbed Project Nim, the experiment was the brainchild of Herbert S. Terrace, a psychologist at Columbia University. His goal was to teach a chimpanzee American Sign Language in order to refute Noam Chomsky’s assertion that language is an exclusively human trait. Nim Chimpsky, the baby chimp at the center of this ambitious, potentially groundbreaking study, was “adopted” by one of Dr. Terrace’s graduate students and brought home to live with her and her large family in their elegant brownstone on the Upper West Side of Manhattan. At first Nim’s progress in learning ASL and adapting to his new environment exceeded all expectations. His charm, mischievous sense of humor, and keen, sometimes shrewdly manipulative understanding of human nature endeared him to everyone he met, and even led to guest appearances on Sesame Street, where he was meant to model good behavior for toddlers. But no one had thought through the long-term consequences of raising a chimp in the human world, and when funding for the study ran out, Nim’s problems began. Over the next two decades, exiled from the people he loved, Nim was rotated in and out of various facilities. It would be a long time before this chimp who had been brought up to identify with his human caretakers had another opportunity to blow out the candles on a cake celebrating his birthday. No matter where he was sent, however, Nim’s hard-earned ability to converse with humans would prove to be his salvation, protecting him from the fate of many of his peers. Drawing on interviews with the people who lived with Nim, diapered him, dressed him, taught him, and loved him, Elizabeth Hess weaves an unforgettable tale of an extraordinary and charismatic creature. His story will move and entertain at the same time that it challenges us to ask what it means to be human, and what we owe to the animals who so enrich our lives.

Language Learning by a Chimpanzee: The Lana Project brings together several disciplinary endeavors, such as primatology, experimental psychology, cognitive psychology, computer and information sciences, and neurosciences. This book is composed of two sets of data—one relates to language learning in the chimpanzee, while the other deals with language construction by Homo sapiens. The fundamental issue of mind-brain dualism and difference between man and beast are also covered. This text mainly describes the LANA project that aims to develop a computer-based language training system for investigation into the possibility that chimpanzees may have the capacity to acquire human-type language. This publication is recommended for biologists, specialists, and researchers conducting work on language learning in nonhuman primates.
