The Gorilla Foundation is a non-profit organization founded in 1976 by Francine Patterson and Ronald Cohn [1] [2] with Barbara F. Hiller. [3]
It was created in order to purchase a female western lowland gorilla named Koko from the San Francisco Zoo. Patterson had been attempting to teach Koko American Sign Language since 1972, under custody of the zoo. In 1974, Patterson moved the project from a trailer at the zoo to a new compound at Stanford University, yet there was a possibility that Koko would need to be returned to the zoo, so Patterson raised money to buy and keep her. After the purchase, the foundation continued to support Patterson's research as she worked with Koko, in order to research language acquisition by non-human animals.
Besides Koko, the foundation also kept two male gorillas: Michael from 1976 until his death in 2000, and Ndume from 1991 until his return to the Cincinnati Zoo in 2019. Koko died in 2018, and after her death followed by the transfer of Ndume, the foundation no longer had any gorillas on which to conduct research.
Patterson had worked with Koko since 1972, [4] when she began teaching the then 1-year-old gorilla American Sign Language (ASL). Patterson planned to continue her scientific experiment designed to determine whether, if it were raised using sign language, a gorilla would learn to use language.
Patterson fed and cared for Koko as she would her own child, and the pair formed a mother/child emotional bond. [5] [ better source needed ] Koko was first moved from the San Francisco Children's Zoo to a private trailer on the zoo in 1973, and then moved to a campus at Stanford University in 1974. After purchasing Koko, the foundation moved her into a trailer near Patterson's home in Woodside, California. [6] In 1976, The Gorilla Foundation acquired Michael, a gorilla born in Cameroon who was allegedly orphaned after his parents were killed for meat, as a potential language-using mate for Koko. [7]
Patterson and her assistants used simultaneous spoken English and ASL when speaking with the gorillas. Patterson has published several papers claiming that Koko has developed a vocabulary of 1000 to 2000 words. The claims that Koko has invented compound words, and uttered meaningful sentences have been widely rejected and face significant methodological criticisms. [8] Under Patterson's criterion for acquisition of a language term, which must be "recorded by two independent observers and be used spontaneously and appropriately on at least half the days of a given month", Koko had learned 264 signs in the first five and a half years of training.
Beginning in the 1990s, the Foundation tried to raise money to move their operation from its sole location in Woodside, California, to a new ape preserve in Maui. [9] They hoped that Koko would successfully mate with her partner, Ndume, who had arrived in 1991, and spontaneously teach their offspring to use sign language. [4] [10] Land was leased in Maui in 1993, but in 2010 The Gorilla Foundation decided that the lease was not secure enough to start work, and decided to focus on the Woodside site instead. [11]
In 2018 Koko died, activating a section of Ndume's loan agreement with the Cincinnati Zoo, which said that Ndume would be placed in an "Association of Zoos and Aquariums" institution after Koko's death. [12] Patterson tried to prevent the move, citing concerns about Ndume's health, which led to a lawsuit resulting in Ndume's removal in June 2019. [13] [14]
According to the Foundation's website, Patterson and other employees have partnered with conservation organizations including International Fund for Animal Welfare and Pan African Conservation Education. The Gorilla Foundation has attempted education projects to decrease the consumption of bushmeat. [15]
During a question-and-answer period, in response to a question as to whether her findings would ever be scientifically proven by duplicating them in an independent experiment, Patterson stated that she believes it would not be ethical to do it again because she believes that it is not right to keep such animals in such unnatural circumstances. [16]
Patterson was accused of sexual discrimination in 2005 by reportedly expecting female volunteers to show their breasts to Koko. This led to a lawsuit, during which said volunteers were fired. [17]
The notion the gorillas actually learned language is widely rejected by linguists and other experts. [18] [19] [20] A common criticism is that most of the signs they used were used chaotically in order to meet a goal, without regard for sentence structure, making them not true language. However, the differences between sign languages and spoken languages have been used to help understand the gorillas' language acquisition, and Koko has erroneously been described as using language in advanced ways, such as symbolic descriptions, lying, and making jokes. [21]
Former employees of The Gorilla Foundation criticized the methods used to care for Koko and her male companion Ndume. In 2012, nine staff members including caregivers and researchers out of "roughly a dozen" resigned, and several submitted a letter to the board to explain their concerns. Former caregiver John Safkow stated that all members of the board left after the walkout, except for Betty White. A pseudonymous source, "Sarah," told Slate that Koko's diet included an excess of processed meat and candy, and that Koko was given a traditional Thanksgiving dinner yearly. The source stated that the official diet they were told to give Koko was appropriate, but that Patterson would visit and feed her "chocolates and meats." Koko's weight of 270 pounds (122 kg) was higher than would be normal for a female gorilla in the wild, approximately 150–200 pounds (70–90 kg); the foundation stated that Koko "is, like her mother, a larger frame Gorilla." [22] Multiple employees corroborated the claim that both Koko and Ndume were given "massive" numbers of supplements on the recommendation of a naturopath; Safkow recalled that the number was between 70 and 100 pills per day, and "Sarah" claimed that various inappropriate foods like smoked turkey, pea soup, non-alcoholic beer, and candy were used as treats to coax Koko to take the pills. The Gorilla Foundation stated that Koko took "between 5 to 15 types of nutritional supplements" and acknowledged their use of homeopathic remedies. [22]
Several former caregivers at The Gorilla Foundation also raised concerns that Koko's companion Ndume was being neglected. In 2012, a group of former employees reached out to a blogger who focused on the ape caregiver community, who in turn asked the USDA Animal and Plant Health Inspection Service (APHIS) to follow up on the claims. After an investigation, APHIS reported that Ndume had been neglected in some aspects; for instance, he had not been Tuberculosis tested in 20 years, despite the recommendation being to test gorillas for Tuberculosis yearly. [22]
Gorillas are herbivorous, predominantly ground-dwelling great apes that inhabit the tropical forests of equatorial Africa. The genus Gorilla is divided into two species: the eastern gorilla and the western gorilla, and either four or five subspecies. The DNA of gorillas is highly similar to that of humans, from 95 to 99% depending on what is included, and they are the next closest living relatives to humans after chimpanzees.
Hanabiko, nicknamed "Koko" was a female western lowland gorilla. Koko was born in San Francisco Zoo, and lived most of her life at The Gorilla Foundation's preserve in the Santa Cruz Mountains. Koko came to prominence as a result of news stories mirroring claims of her handler, Francine Patterson, that Koko had demonstrated significant linguistic abilities. Despite continued popular perception of Koko’s abilities with sign language, these claims are widely rejected by the scientific community and Patterson’s work has faced substantial methodological and ethical criticism.
Neam "Nim" Chimpsky was a chimpanzee used in a study to determine whether chimps could learn a human language, American Sign Language (ASL). The project was led by Herbert S. Terrace of Columbia University with linguistic analysis by psycholinguist Thomas Bever. Chimpsky was named as a pun on linguist Noam Chomsky, who posited that humans are "wired" to develop language.
Washoe was a female common chimpanzee who was the first non-human to learn to communicate using some American Sign Language (ASL) as part of an animal research experiment on animal language acquisition.
Kanzi, also known by the lexigram , is a male bonobo who has been the subject of several studies on great ape language. According to Sue Savage-Rumbaugh, a primatologist who has studied the bonobo throughout her life, Kanzi has exhibited advanced linguistic aptitude.
Francine "Penny" Patterson is an American animal psychologist. From 1972 onwards, she taught a modified form of American Sign Language, which she called "Gorilla Sign Language" (GSL) to a gorilla named Koko. The scientific validity of Patterson's claims about the extent of Koko's language mastery has been widely rejected in linguistic and other specialist circles.
Ronald Herbert Cohn was an American zoologist who was a long-time research collaborator of psychologist Francine Patterson in her work in training Koko the gorilla in the use of American sign language. He documented much of Koko's life on film and on camera, and is credited as the illustrator for the children's books Koko's Kitten, Koko-Love!: Conversations With a Signing Gorilla, and Koko's Story. One of his photos of Koko was featured on the cover of National Geographic in 1978 and 1985.
Research into nonhuman great ape language historically involved attempts to teach chimpanzees, bonobos, gorillas and orangutans to communicate using imitative human speech, sign language, physical tokens and computerized lexigrams. These studies were controversial, with debate focused on the definition of language, the welfare of test subjects, and the anthropocentric nature of this line of inquiry.
Chantek, born at the Yerkes National Primate Research Center in Atlanta, Georgia, was a male hybrid Sumatran/Bornean orangutan who acquired the use of a number of intellectual skills, including some modified American Sign Language (ASL), taught by American anthropologists Lyn Miles and Ann Southcombe. In Malay and Indonesian, cantik means "lovely" or "beautiful".
The western lowland gorilla is one of two Critically Endangered subspecies of the western gorilla that lives in montane, primary and secondary forest and lowland swampland in central Africa in Angola, Cameroon, Central African Republic, Republic of the Congo, Democratic Republic of the Congo, Equatorial Guinea and Gabon. It is the nominate subspecies of the western gorilla, and the smallest of the four gorilla subspecies.
Cecil Holden Patterson (1912–2006) was an American psychologist and writer. He was an emeritus professor of psychology at the University of Illinois at Urbana-Champaign in the United States. He worked directly with Carl Rogers and practiced person-centered (Rogerian) therapy throughout his career.
Michael was a male gorilla involved in experiments to teach apes sign language. He is alleged to have had a working vocabulary of over 600 signs in American Sign Language, taught to him by Koko, a female gorilla; Francine Patterson; and other staff of Stanford University. Michael, an orphan, spent most of his life in Woodside, California, where he became known for painting. Both Michael and Koko’s linguistic abilities are widely rejected by specialists, despite popular perception to the contrary.
Interspecies communication is communication between different species of animals, plants, or microorganisms. Although researchers have explored the topic for many years, only recently has interspecies communication been recognized as an established field of inquiry.
Koko: A Talking Gorilla is a 1978 French documentary film directed by Barbet Schroeder that focuses on Francine Patterson and her work with Koko, the gorilla. Patterson claims to have taught Koko to communicate with humans using symbols taken from American Sign Language. The film was screened in the Un Certain Regard section at the 1978 Cannes Film Festival.
Harambe was a western lowland gorilla who lived at the Cincinnati Zoo. On May 28, 2016, a three-year-old boy visiting the zoo climbed under a fence into an outdoor gorilla enclosure where he was violently grabbed and dragged by Harambe. Fearing for the boy's life, a zoo worker shot and killed Harambe. The incident was recorded on video and received broad international coverage and commentary, including controversy over the choice to use lethal force. A number of primatologists and conservationists wrote later that the zoo had no other choice under the circumstances, and that it highlighted the danger of zoo animals near humans and the need for better standards of care.
Charles the Gorilla is a wild-born western lowland gorilla from Gabon, West Africa. Although the date of his birth is unknown his approximate date of birth is September 23, 1972; it is, however, celebrated on January 19 each year. At a time when humans were less vigilant about their treatment of threatened and endangered species, Charles was sought after by a group of poachers interested in acquiring gorillas for international trade. He is thought to have been found lying next to the corpse of his dead mother.
A talking animal or speaking animal is any non-human animal that can produce sounds or gestures resembling those of a human language. Several species or groups of animals have developed forms of communication which superficially resemble verbal language, however, these usually are not considered a language because they lack one or more of the defining characteristics, e.g. grammar, syntax, recursion, and displacement. Researchers have been successful in teaching some animals to make gestures similar to sign language, although whether this should be considered a language has been disputed.
Ronald Theodore Reuther (1929–2007) was a committed naturalist who spent decades managing and improving several major zoos, and was an aviation enthusiast. Armed with a Bachelor of Science in wildlife conservation, Reuther held curator and director positions for the Micke Grove Zoo, the Cleveland Zoo, the Indianapolis Zoo, the San Francisco Zoo, and the Philadelphia Zoo. As director of the San Francisco Zoo, Reuther was instrumental in the creation of a project to teach the gorilla Koko sign language. As a member of the Association of Zoos and Aquariums, Reuther helped to advance the transformation of zoos into research centers, and to promote the conservation and care of wildlife. As an aviation enthusiast, Reuther founded the Western Aerospace Museum and pursued the study of his personal interest in the disappearance of pilot Amelia Earhart.
Ndume is a male western lowland gorilla known for having learned a limited amount of a modified version of American Sign Language (ASL) and for being at the center of lawsuit over his custody between the Cincinnati Zoo and the Gorilla Foundation. Ndume has lived most of his life at the Gorilla Foundation's sanctuary at Woodside, California, but has also lived at the Cincinnati Zoo and the Brookfield Zoo. Following a lawsuit, which raged on for months, Ndume was transferred back to the Cincinnati Zoo from the Gorilla Foundation on June 14, 2019.
