Historical Overview of the Study of Animal Cognition
Early Pioneers
Charles Darwin (1871) - the first person to suggest the possible continuity of cognitive processes
among different species. ( See Darwin, C. (1871), The descent of man and selection in relation to
sex. London: Murray.
According to Darwin, “The difference in mind between man and the higher animals; great as it is,
certainly is one of degree and not of kind” (Darwin, 1871, p.128).
The mechanisms responsible for evolution shaped not only a species’ anatomical characteristics
but also its psychological traits, called “mental faculties” by Darwin. He referred to “faculties” as
curiosity, imitation, attention, memory, and reasoning. (Vauclair, 1996, p.2).
Even though Darwin accepted the existence of “beliefs” in animal species equivalent to those found
in humans, he remained cautious about attributing language and consciousness to any higher-order
nonhuman species. (Vauclair, 1996, p.2.)
Nevertheless, he considered that some elements of language were already present in animal
communication (bird songs and primate vocalizations) and that those elements, when combined
with novel mental abilities, would inevitably lead to human language. (Vauclair, 1996, p.2).
Because Rene Descartes believed animals to be machines, Darwin’s emphasis on continuity
among all species brought some “humanity” back to the animals.
More important, his ideas have made the study of animal behavior an essential tool for understanding
human behavior.
According to Vauclair (1996): “In effect, if one accepts that the human species is the product of
some ancestral nonhuman forms, then the study of animals’ mental functions becomes indispensable
for understanding the biological precursors of the human mind. (P.2).
George Romanes
He placed animal mental functions within the context of learning abilities.
According to Romanes, an organism can make novel adjustments or change old adaptations as a
result of its experience.
He was the first to investigate systematically the comparative psychology of intelligence using an
anecdotal method.
This interest in learning capacities was further developed by other comparative psychologists,
including Morgan (1894), Loeb (1900), Washburn (1908), Jennings (1906), Thorndike (1911),
and Yerkes (1911).
C.L. Morgan
Wrote a book on: The animal mind.
Warned against the danger of interpreting an action by reference to a higher mental faculty when it might
be explained by a lower-order schema.
Wrote about observations made on his dog when his dog learned to lift the latch of the garden gate
and let himself out. Attempted to outline the process or steps leading to an “intelligent” behavior.
Ivan Pavlov
Discovered the conditioned response. We use the term “Classical Conditioning.”
Also winner of the 1904 Nobel Laureate in Medicine in recognition of his work on the physiology of
digestion, “through which knowledge on vital aspects of the subject has been transformed and enlarged.”
(1849-1936). Born in Ryazan Russia. Studied medicine at St. Petersburg (Russia). Affiliated with the
Institute of Experimental Medicine and the Military Medical Academy (St. Petersburg).
Worked on the physiology of circulation and digestion. Definitive work and lectures on conditioned reflexes.
Edward L. Thorndike
Conducted the first empirical and theoretical analyses of animal learning.
Pioneered the use of “puzzle boxes” and “mazes” to study species such as rabbits, cats, and rats.
He was a psychologist, born in Williamsburg, MA. Studied at Wesleyan University and Harvard.
Taught at Teachers College at Columbia University, where he worked on educational psychology
and the psychology of animal learning.
As a result of studying animal intelligence, he formulated his famous “law of effect,” which states
that a given behavior is learned by trial- and- error, and is more likely to occur if its consequences
are satisfying.
His works include Psychology of learning (1914) and The measurement of intelligence (1926).
Robert Mearns Yerkes
1876-1956. American psychobiologist, noted for his studies of the anthropoid apes. He was an
authority on experimental primate psychology.
Born in Pennsylvania and educated at Ursinus College and Harvard University.
Taught at Harvard (1902-1917) and the University of Minnesota (1917-1919). Yale University (1924-1944).
Was in charge of psychological testing for the armed forces during WWI.
Was chairman of the research information service of the National Research Council until 1924.
In 1929, Yerkes organized the Yerkes Laboratories of Primate Biology, Inc., at Orange Park, Florida.
He wrote : The mental life of monkeys and apes (1916); The mind of a Gorilla (1927); and Chimpanzees:
A laboratory colony (1943).
Wolfgang Kohler
Developed first cognitive analysis of learning in animals.
A psychologist trained at the University of Berlin. Was working at a primate research facility maintained
by the Prussian Academy of Sciences on Tenerife in the Canary Islands when the WWI broke out.
Marooned there, he had at his disposal a large outdoor pen and nine chimpanzees of various ages.
The pen, described by Kohler as a playground, was provided with a variety of objects, including boxes,
poles, and sticks, with which the primates could experiment.
Kohler set the chimps a variety of problems, each of which involved obtaining food that was not
directly accessible.
Kohler discovered that chimpanzees readily find indirect routes to goals when necessary.
E.C. Tolman
1886-1959. Was the first researcher to prove that rats can plan novel behavior. Tolman was
the first to discover that rats had the ability to form a “cognitive map” of a maze.
Konrad Lorenz
Was Austria’s most famous scientist, held doctorates in medicine, zoology and psychology.
Played a key role in the development of the ethological study of animal behavior. Conducted studies
on the organization of individual and group behavior patterns.
Discovered “imprinting” a rapid and nearly irreversible learning process occurring early in life.
He found that young animals become strongly attached to their biological mothers, but that the process
30 hours will usually not imprint.
Imprinting is primarily triggered by visual cues and auditory stimuli. It is cue specific and relies on a
hierarchy of remembered stimuli.
Winner of the 1973 Nobel Prize for his pioneering studies of human and animal behavior, along with
Karl von Frisch and Nikolaas Tinbergen.
Dr. Lorenz turned to research in animal behavior shortly after obtaining his medical degree.
He had become an animal lover as a child, collecting a variety of animals at his expansive boyhood
home outside Vienna. The collection included fish, dogs, monkeys, insects and especially ducks and geese.
His first studies was on the social life of birds.
One of his most controversial publications was the 1966 study, “On Aggression,” in which he
asserted that aggressive impulses are to some degree innate, drawing on analogies between
human and animal behavior.
Later best-selling books included: The Eight Deadly Sins of Civilized Humanity, a plea
against overpopulation and environmental destruction; and, The Decay of the Humane, a gloomy look
at humankind’s future which sold 390,000 copies.
Taught at Immanuel Kant University in Koenigsberg and at the University of Vienna.
Died in April 1989 at 85 years.
Karl von Frisch
1886-1982. Austrian zoologist. Lived in Germany. Worked at the Zoology Institute at the University
of Munich.
Known for his pioneering work in comparative behavioral psychology, particularly his studies of the
complex communication between insects.
He shared the 1973 Nobel Prize in medicine with Lorenz and Tinbergen.
An important implication of his work is that behavioral continuity exists between animal communication
and human language. He switched to working on honey bees early in the century.
Nikolaas Tinbergen
Dutch/British zoologist noted for his studies of animal behavior. He was born in the Netherlands (Hague).
He shared the Nobel prize with Lorenz and von Frisch for his work in reviving and developing the science
of animal behavior.
Began his studies of animal behavior as a child. Was educated and taught at the Leiden University and
then joined the faculty at the University of Oxford, England.
Published a book The Herring Gull’s World (1960) in which he describes his studies with gulls for which
he is best known, including an examination of food-begging techniques.
His studies of the display behavior of certain species revealed that such displays result from a state
of conflict between opposing motivations (fight or flee). He also clarified the evolutionary origins of
many social signals and their subsequent ritualization.
Beatrix Gardner studied under Tinbergen.
W. H. Furness
Reported to the American Philosophical Society in 1916 that he had taught an orangutan, the
Asian great ape, to say the words “pap” and “cup.” His orangutan died from a high fever while
saying “papa cup” over and over.
J.B. Watson
Watson firmly condemned the studies of early comparative psychologists and their attempts to
describe the life of animals in its totality, including animal consciousness.
Proposed a descriptive approach. Believed that the study of animal behavior should be limited
to relations between environmental stimulations and reactions of organisms to those stimulations.
B.F. Skinner
Originated important ideas about behaviorism and operant conditioning.
A major figure in the field of behaviorism and is considered to be the father of operant conditioning.
With pigeons, he developed the ideas of “operant conditioning, “shaping behavior,” and “reinforcement.”
Operant conditioning is a term Skinner applied to a process in which learning or behavioral change
takes place as a result of reinforcing (rewarding) the desired behavior and withholding the reward or
actively punishing undesired behaviors.
Examples are teaching a dog new tricks, and rewarding behavior change in mental patients.
Current Pioneers
Jane Goodall
Jane has spent more than 35 years studying the ways of chimpanzees in the wild.
She was born in London on April 3, 1934 and grew up on the southern coast of England.
She began studying chimpanzees in the wild in Gombe, Tanzania in 1960.
She received her doctorate in ethology at Cambridge University.
She founded the Gombe Stream Research Center for the study of chimpanzees and baboons.
In 1975 she established the Jane Goodall Institute for Wildlife Research, Education, and conservation
to promote animal research throughout the world.
She has written many books and articles on her work, including In the Shadow of Man and Reason
for Hope: A Spiritual Journey.
Dr. Goodall was named Commander of the British Empire by Queen Elizabeth II. She also received
the prestigious Kyoto Prize in Basic Science and the National Geographical Society’s Hubbard Award
for distinction in research, exploration and discovery.
Dian Fossey
1932-1985. An American zoologist who became the world’s leading authority on the mountain
gorilla. Completed her doctoral work at University of Cambridge in England.
Persuaded by Louis Leakey to study the Gorilla, she established the Karisoke Research Center in 1967
and began a hermit like existence in Rwanda’s Virunga Mountains, which was one of the last bastions of
the endangered mountain gorilla.
Through patient effort, Fossey was able to observe the animals and accustom them to her presence, and
the data she gathered greatly enlarged contemporary knowledge of the gorilla’s habits, communication,
and social structure.
In 1980, she returned to the U.S. to accept a visiting professorship at Cornell University. While teaching,
she completed her book, Gorillas in the Mist (1983).
She was actively involved in stopping poachers from harming the wild animals. On December 16, 1985,
her slain body was found near her campsite. It is assumed she was killed by poachers against whom she
had struggled for so long.
First she adopted the strategy of sneakingup silently on the gorillas and quietly observing. Later, though,
she changed her approach by announcing her presence and by imitating their sounds. After six months
she was able to approach some of the groups as close as thirty feet.
The life of mountain gorillas was recorded in detain by Fossey. The group is usually a tightly-knit
family consisting of an adult male leader, his adult brother, or nephew, and a few adult females and
their children. They move and feed together, rarely separated by more than a hundred feet. The children
are treated very tenderly by even the largest of males. The adult males are often referred to as
“silverbacks” because the fur on their backs turn gray as they age.
Keith and Catherine Hayes
In the late 1940s psychologist Keith Hayes and his wife, Catherine, home raised a newborn chimpanzee
named Viki. After six years of intensive and creative vocal training, Viki could whisper four words:
“mama,” “papa,” “cup,” and “up.”
These were all made with a heavy and largely voiceless chimpanzee accent.
Allen and Beatrix Gardner
Conducted pioneering work and study on the linguistic capabilities of apes.
Used the technique of cross-fostering; that is, raising apes in a natural environment as if they were children.
Best known for the innovation of teaching sign language to cross-fostered chimps which began with
Project Washoe in 1966. Washoe was taught a form of American Sign Language.
The Gardners replicated and extended Project Washoe with four other chimpanzees, Moja, Pili, Tatu
and Dar who lived like human children from birth.
Beatrix died suddenly on June 5, 1995, in Padua, Italy while on a European lecture tour.
So far the Gardners have only reported main outlines of the extensive records of their 5 subjects.
They have created more than 35,000 pages of handwritten notes and many hours of film and videotape.
The University of Nevado, Reno has established the UNR Primate Research Fund in her memory.
Write to UNR Foundation, Beatrix Gardner Memorial Fund, Mailstop 162, Reno, NV 89557.
Roger and Debbie Fouts
Currently at Central Washington University’s Chimpanzee and Human Communication Institute (CHCI).
Roger Fouts is CO-director of the Institute and Professor of Psychology and a Distinguished
Research Professor at CWU. His background is in experimental psychology and comparative
psychology with a specialty in animal behavior (ethology). He specializes in primate behavior,
particularly chimpanzee behavior. He has published more than 70 scientific articles and books.
His famous book on his work over 30 years is Next of Kin, about his work with Washoe. Fouts also
houses and works with Loulis, Dar, Moja, and Tatu, all originally cross-fostered by Allen and Beatrix Gardner.
Roger and Debbie Founts founded Friends of Washoe, a non-profit organization dedicated to the welfare
of chimpanzees and other fellow animals. In 1992, they founded the Chimpanzee and Human
Communication Institute (CHCI) at CWU.
Recent research at the CHCI has focused on the private signing of the chimpanzees, imaginary play
and signing, chimpanzee to chimpanzee conversations, conversation repair, representational drawing,
and the symbolic representation of spatial relations with ASL signs.
The Foutses are beginning a new research direction and will be studying four different free-living
communities of chimpanzees in Africa to record and analyze their behavior for gestural dialects.
John C. Lilly
Is a physician and psychoanalyst specializing in biophysics, neurophysiology, electronics, computer
theory, and neuroanatomy.
He is inventor of the isolation tank method of exploring consciousness. This work led him to
interspecies communication research projects between man and dolphin.
Did early controversial work on dolphin’s ability to talk. Go to his web page to listen to the dolphin
Lilly has spent 23 years working with dolphins. He founded the Human/Dolphin Foundation. His lab is
in the Virgin Islands.
Ken Marten
Project Delphis is a conservation effort to save wild dolphins, as well as a dolphin behavior and
cognition research project.
Their purpose is to save the dolphins in the ocean from the holocaust they are currently experiencing
by learning everything about their intelligence and sharing these finds with the global public in an effort
to raise their understanding and awareness.
The are located at Sea Life Park in Honolulu, Hawaii where they have an underwater viewing laboratory
and conduct research on perception and self-consciousness.
Ken Marten is the principal investigator at Project Delphis. He is an experienced animal cognition
researcher and former observer on purse-seine tuna boats.
Louis Herman
Founded the Kewalo Basin Marine Mammal Laboratory (KBMML) in Honolulu, Hawaii in 1969. It
was conceived as a research and educational facility dedicated to the laboratory and field study of
dolphin and whale behavior, including species resident in Hawaiian waters.
It is the only facility of its kind devoted entirely to the study of dolphin cognition, communication,
and intelligence.
The Dolphin Institute was founded in 1993 by Louis Herman and Adam Pack and several friends of the
25 year old Kewalo Basin Marine Mammal lab. It is an evolution of KBMML. TDI is relocating to a new
site because the Hawaiian government has asked the KBMML to relocate its facilities to another area
to make room for an expansion of Kewalo Basin Park.
Dr. Herman is a pioneer in studies of dolphin perception, intelligence, concept formation, and
language competencies. He also pioneered KBMML’s studies of the social organization and
behavior, migratory habits, mating strategies, and communication systems of North Pacific humpback
whales, in Hawaii and southeast Alaska.
Dr. Herman is a tenured professor at the University of Hawaii with appointments in Psychology
and Oceanography. He oversees all operations of the laboratory.
H. Lyn Miles
A biocultural anthropologist interested in the evolution of human symbol systems, how cultural processes
interact with language and evolution, and what orangutans can tell us about language and intelligence.
She cross-fostered Chantek and began her work with him at 9 months of age in a trailer on the campus
of the University of Tennessee at Chattanooga. She taught him the human culture and American Sign
Language. Chantek had a pet squirrel and cat; asked to go for car rides to the lake, park and fast food
restaurants, and even went to the circus.
Chantek has a vocabulary of over 150 signs after several years and comprehends the spoken English
language.
Founded the Chantek Foundation to support cultural research with Chantek, an orangutan that Lyn has
been working with for more than 20 years.
The foundation seeks support to understand the nature of orangutan communicative ability and intelligence,
to foster the development of orangutan and other great ape persons in a primate cultural center and to
promote orangutan conservation through awareness.
In 1986, Project Chantek moved to the Division of Behavioral Biology at the Yerkes Regional Primate
Research Center, and in 1997, Project Chantek moved to Zoo Atlanta where Dr. Miles’ research with
Chantek continues.
Lyn Miles received her PH.D. in Anthropology from the University of Connecticut. Also did course work
at Yale University and the University of Oklahoma. She is currently professor of Anthropology at the
University of Tennessee at Chattanooga and Senior Research Fellow at Zoo Atlanta. She lives in
Atlanta since 1993.
She is coeditor of The Mentality of Gorillas and Orangutans. She is currently working on a book,
Chantek: The Enculturated Orangutan.
She teaches courses in physical anthropology, primate behavior, ape language, and cognitive and linguistic anthropology.
Sally Boysen
Has been studying primate cognition at Ohio State University for more than 20 years. She received her
Ph.D. in 1984 from Ohio State.
Her current research interests are animal cognition, with particular interest in the acquisition of counting
abilities and numerical competence in nonhuman primates, cognitive development in great apes,
including attribution, self-recognition, and intentional behavior, and social behavior and tool use in
captive lowland gorillas.
She has conducted collaborative research with Gary Berntson on the application of noninvasive psycho
physiological measures to attention and cognition in primates, and cardiac indices of visual and auditory
recognition in the great apes.
She is currently raising money to build a new primate research facility on the Ohio State campus.
Her chimpanzees live in elaborate furnished facilities with chairs and the furnishings of a home or apartment.

Francine G. “Penny” Patterson
For 25 years, Francine Patterson has been communicating with Koko, a gorilla. She began to study
communication with Koko by means of sign language in 1972.
She received her doctorate in developmental psychology from Stanford University in 1979.
She founded and is President of the Gorilla Foundation which serves as a trust on behalf of Koko
and the other gorillas she works with. Founded in 1976, the Gorilla Foundation promotes study and
preservation of gorillas and other endangered primates. “Project Koko,” is a primary focus of the
foundation and focuses on gaining insights into the mind of another species through language.
There were originally three gorillas at the Foundation, Koko, Michael and Ndume. Michael recently
died in April. Koko is still mourning Michael’s death.
Koko’s and Michael’s art is world renowned.
The Gorilla Foundation will soon be moving its home to Maui, Hawaii, where ground breaking ceremonies
will take place on October 12, 2000 for the Allan G. Sanford Sanctuary, a unique refuge for these primates.
The sanctuary will be part of the Koko Preserve, which will also encompass the high-tech Koko visitor
center and will allow for live virtual interactions with Koko and observation of her family via virtual viewing
of the sanctuary.
Irene M. Pepperberg
Works with the parrot, Alex. Interested in avian communication.
Since 1977, Dr. Pepperberg’s studies in Ethology and animal-human communications have provided
insight into the capabilities of parrots to talk and to understand. Interested in interspecies communication
and conceptual behavior.
She currently works with 3 Congo African Grey Parrots. Alex, the oldest, can count, identify objects,
shapes, colors and materials. Alex also knows the concepts of same and different. They have now
begun to work with phonics and there is evidence to believe that one day Alex may be able to read.
Dr. Pepperberg believes that her work has far reaching implications:
Studies of avian versus mammalian brain function: Given that the avian brain can process
information in similar ways, Dr. Pepperberg’s procedures may assist clinicians who are
devising programs for brain-damaged humans.
Programs for teaching language to dysfunctional children: Dr. Pepperberg’s training techniques
are being used for developmentally delayed children.
Targeting parrots for wildlife conservation initiatives: If parrots are as intelligent as chimpanzees
and dolphins, shouldn’t we make the same attempts to save them and their habitat as we are
making for these other species?
Dr. Pepperberg is currently associate professor in the department of ecology and evolutionary biology at
the University of Arizona at Tucson, with a joint appointment in Department of Psychology and an affiliate
in the program in neuroscience.
Frans B. M. De Waal
Was trained as an ethologist in the European tradition. He received his Ph.D. from the University of Utrecht
in 1977.
After a six-year study of the chimpanzee colony at the Arnhem Zoo, he moved to the U.S. in 1981 to work
on other primate species, including bonobos.
He is a research professor at the Yerkes Regional Primate Research Center, Candler Professor of
Primate Behavior, Professor of Psychology, and Director of the Living Links Center at Emory University
in Atlanta.
He is a world-renowned primatologist. He has authored several books, including Chimpanzee Politics
(1982); Good Natured: The Origins of Right and Wrong in Humans and Other Animals (1996); and
Bonobo: The Forgotten Ape (1997).
He has also published on the sexual habits of Bonobos and their sense of self-esteem.
Matsuzawa Tetsuro
Works at the Primate Research Institute at Kyoto University in Japan.
Works with the chimpanzee, Ai.
Uses lexigrams to study language abilities in chimpanzees. Ai has learned to write the alphabets.
Rob Shumaker
Coordinates the Orang utan Language Project (OLP) at the National Zoo’s think tank.
Orangs cross overhead between the Great Ape House and the Think Tank building via tall towers and
long vinyl-covered cables.
Shumaker is teaching the orangs a language composed of abstract symbols. He also focuses on how
their knowledge of this language will be transferred and possibly taught to other orangs not instructed
by trainers.
The language is a computer based form designed by Shumaker and centered on abstract symbols that
each represents a word.
Words are broken down into seven categories: food, activities (verbs), adjectives, non-food objects,
human names, orang names, and numbers. Each category has a distinct exterior shape. For example,
food items are characterized by rectangles. Verb activities are defined by diamond shapes.
Marc Hauser
Professor of Psychology at Harvard University in the Department of Psychology. Conducts primate research.
He and his colleagues have found that monkeys such as the cotton-top tamarin can distinguish between
two languages, an ability once thought to be exclusively human.
Hauser believes that humans inherited the ability to process speech from ancestors that they have in
common with monkeys and apes.
He says that monkeys can tell the difference between Dutch and Japanese as easily as human infants.
Sue Savage-Rumbaugh
Sue Savage-Rumbaugh says that the overarching goal of the research undertaken by her Center was
to develop technologies and teaching strategies designed to facilitate the learning of language by
persons with mental retardation.
She has worked with a number of chimpanzees and is now working with the Bonobo ape-Kanzi and family.
Kanzi is a lab reared Bonobo and his training has led to his acquisition of linguistic and cognitive
abilities similar to a 2 year old.
Sue Savage-Rumbaugh does her work out of Georgia State University, Language Research Center.
She is professor of biology and psychology.
Animal Communication and Human Language
Key Concepts Used to Describe Communication
Representation is defined as the phenomenon by which an organism structures its knowledge with regard to its environment. Knowledge implies a support or a substitute in the knower's mind for the object in the external world. Two types of substitute can be distinguished: internal substitutes (such as indices or images) and external substitutes (such as symbols, signals, or words).
Communication consists of exchanges of information between a sender and a receiver using a code of specific signals that usually serve to meet common challenges (reproduction, feeding, protection) and, in group living species, to promote cohesiveness of the group.
Language is a system that is both communicatory and representational. It is grounded in a social convention that attributes to certain substitutes (the words) the power to designate the content (objects) of the communication.
Piaget's Conception of Language
Piaget's conception of language is in agreement with the theory of continuity. For him, language is not a specific entity but a particular aspect of the general capacity for representation: "Language is only one aspect of the symbolic (or semiotic) function. This function is the ability to represent something by a sign or symbol or another object. In addition to language the semiotic function includes gestures...deferred imitation...drawing, painting, modeling." (Piaget, 1970, p.45)
Other Scientists' Conception of Language
Rumbaugh describes language as "an infinitely open system of communication" (1977).
According to Patterson and Linden (1981), some people say that anything an ape can do is not language; of course, if these are the same people who say that language defines us as humans, and an ape can learn sign language, then they are saying that deaf people who use sign language are not human (p.119-120).
Charles Hockett (1960) identifies 13 design features of human language that may in theory be present in any other communicatory system. These are:
vocal auditory channel;
Broadcast transmission and directional reception;
rapid fading (transitoriness);
interchangeability: a speaker can reproduce any linguistic message he can understand;
total feedback: the speaker of a language hears everything of linguistic relevance in what he himself says;
specialization: sound waves of speech serve only as signals;
semanticity;
arbitrariness;
discreteness;
displacement;
productivity;
traditional transmission;and
duality of patterning.
According to Hockett, features 1 to 5 (vocal auditory channel, broadcast transmission and directional reception, rapid fading, interchangeability and total feedback) are shared by many animal species, among them several birds and most of the mammals; specialization, semanticity, and arbitrariness (features 6-8) can be found in primates only, whereas discreteness and traditional transmission are specific to hominoids.
Hockett believes that the features of displacement, productivity, and duality of patterning appear with human speech only. Displacement describes the ability to evoke things that are remote in space and time. Productivity concerns the ability to say things that have never been said before and yet to be understood by other speakers of the language. Duality of patterning related to the two-level organization of language: words as meaningful or "morphemes" (level 2) are made of meaningless sounds or "phonemes" (level 1).

The Emotional Lives of Animals
Excerpts from When elephants weep: The emotional lives of animals, by Jeffrey Moussaieff Masson & Susan McCarthy, New York: Delta, 1995)
Animals cry. At least, they vocalize pain or distress, and in many cases seem to call for help. Most people believe, therefore, that animals can be unhappy and also that they have such primal feelings as happiness, anger, and fear. The ordinary layperson readily believes their dog, cat, parrot, or horse, feels. They not only believe it but have constant evidence of it before their eyes. (Masson & McCarthy, 1995, p. xii).
In his book, The expression of the emotions in man and animals, Charles Darwin dared to imagine a dog's conscious life: "But can we feel sure that an old dog with an excellent memory and some power of imagination, as shown by his dreams never reflects on his past pleasures in the chase? And this would be a form of self-consciousness." Even more evocatively, he asked: "Who can say what cows feel, when they surround and stare intently on a dying or dead companion?" He was unafraid to speculate about areas that seemed to require further investigation. (Masson & McCarthy, 1995, p.xvii)
Masson and McCarthy: "A pivotal book in my thinking about animal emotions was Donald Griffin's The question of animal awareness. Attacked in many quarters upon its publication in 1976, it discussed the possible intellectual lives of animals and asked whether science was examining issues of their cognition and consciousness fairly. While Griffin did not explore emotion, he pointed to it as an area that needed investigation. Convincing and intellectually exciting, it made me want to read a comparable work on animal emotions, but I learned that there was almost no investigation of the emotional lives of animals in the modern scientific literature. (p.xvii)
Why should this be so? One reason is that scientists, animal behaviorists, zoologists, and ethologists are fearful of being accused of anthropomorphism, a form of scientific blasphemy. Not only are the emotions of animals not a respectable field of study, the words associated with emotions are not supposed to be applied to them. Why is it controversial to discuss the inner lives of animals, their emotional capacities, their feelings of joy, disappointment, nostalgia, and sadness? Jane Goodall has recently written of her work with chimpanzees: "When, in the early 1960s,
I brazenly used such words as 'childhood,' 'adolescence', 'motivation,' 'excitement,' and 'mood,' I was much criticized. Even worse was my crime of suggesting that chimpanzees had personalities. I was ascribing human characteristics to nonhuman animals and was thus guilty of that worse of ethological sins-anthropomorphism.
Knowing what we feel is one way to judge whether an animal feels something similar, but may not be the only, or even the best way. Are animals' similarities or differences from humans the only, or even the most important, issue? Surely we can train ourselves to an empathic imaginative sympathy for another species. Taught what to look for in facial features, gestures, postures, behavior, we could learn to be more open and more sensitive. We need to exercise our imaginative faculties, stretch them beyond where they have already taken us, and observe things we have never been able to see before. (p.xxi)
Field studies show what most lay people have always believed: that animals love and suffer, cry and laugh; their hearts rise up in anticipation and fall in despair. They are lonely, in love, disappointed, or curious; they look back with nostalgia and anticipate future happiness. They feel. (p.xxii)
We will have seen that animals feel anger, fear, love, joy, shame, compassion, and loneliness to a degree that you will not find outside the pages of fiction or fable. Perhaps this will affect not only the way you think about animals, but how you treat them. The clearer it became to me that animals have deep feelings, the more outraged I grew at the thought of any kind of animal experimentation. Can we justify these experiments when we know what animals feel as they undergo these tortures? Is it possible to go on eating animals when we know how they suffer? We are horrified when we read, even in fiction, of people who kill other people in order to sell parts of their bodies. But every day elephants are slaughtered for their tusks, rhinos for their horns, gorillas for their hands. My hope is that as it begins to dawn on people what feeling creatures these animals are, it will be increasingly difficult to justify these cruel acts. (p.xxiii)
Anthropomorphism
The greatest obstacle in science to investigating the emotions of other animals has been an inordinate desire to avoid anthropomorphism. Anthropomorphism means the ascription of human characteristics-thought, feeling consciousness, and motivation --to the nonhuman.
Science considers anthropomorphism toward animals a grave mistake, even a sin. It is common in science to
speak of "committing" anthropomorphism. The term originally was religious, referring to the assigning of human form or characteristics to God--the hierarchical error of acting as though the merely human could be divine--hence the connotation of sin. (p.31)
From the belief that anthropomorphism is a desperate error, a sin or a disease, flow further research taboos, including rules that dictate use of language. A monkey cannot be angry; it exhibits aggression. A crane does not feel affection; it displays courtship or parental behavior. A cheetah is not frightened by a lion; it shows flight behavior. In keeping with this, de Waal's use of the word "reconciliation" in reference to chimpanzees who come together after a fight has been criticized: Wouldn't it be more objective to say first post-conflict contact"? In the struggle to be objective, this kind of language employs distance and the refusal to identify with another creature's pain. (p.34)
Against this scientific orthodoxy, the biologist Julian Huxley has argued that to imagine oneself into the life of another animal is both scientifically justifiable and productive of knowledge. (p.34)
Anthropocentrism
The real problem underlying many of the criticisms of anthropomorphism is actually anthropocentrism. Placing humans at the center of all interpretation, observation, and concern, and dominant men at the center of that, has led to some of the worst errors in science, whether in astronomy, psychology, or animal behavior. (p.42)
Anthropocentrism [note: the term is equivalent to ethnocentrism] treats animals as inferior forms of people and denies what they really are. It reflects a passionate wish to differentiate ourselves from animals, to make animals other, presumably in order to maintain humans at the top of the evolutionary hierarchy and the food chain. The notion that animals are wholly other from humans, despite our common ancestry, is more irrational than the notion that they are like us. (p.34)
Play
Joy often expresses itself in play, which many animals indulge in all their lives. Play seems to be both a sign and a source of joy.
Play is important to animals; and, although it carries risks, since animals can be injured or killed while playing, a variety of evolutionary functions for it have been proposed. Perhaps it is a form of practice, of learning to perform tasks, or exercises developing social, neurological or physical capacities....Animals can play in complete solitude or in social situations. Animals also play with objects. Object play can quickly become social play....Teasing is a form of play....some animals tease conspecifics; they may also tease members of other species....Young animals and sometimes adults commonly wrestle, mockfight, and chase one another. Animals sometimes find playmates across the barrier of species. Interspecies play is also found in the wild. (PP 124-132)
What Does the Future Hold for the Study of Animal Cognition? Some Thoughts from the Pioneers and My Concluding Comments
Jacques Vauclair (Animal Cognition, 1996)
Both generalist (Rumbaugh and Pae, 1984) and ecologically oriented investigators (Kamil, 1984) of animal cognition agree that animals in their environment can be described as problem solvers and decision makers. Their common ground is the cognitive dimension of behaviors, which is expressed through the intervention of internalized representations of the environment by a given organism. In effect, the animal has to solve problems in almost all of its daily activities, from negotiating social exchanges to manipulating inanimate objects. The decisional aspect of animal cognition is thus similarly present during foraging as well as during social activities, as when an animal must quickly evaluate different elements in order to act appropriately (for example, flight or fight). In laboratory settings, these decisions are particularly evident in deceptive behaviors and in other forms of dissimulation. (p.168)
It appears that these global functions are performed by the animal in ways that are basically similar to human performance, that is, through the construction and use of representations of various degrees of schematization and abstraction. (p.169)
The interpretation of language as a uniquely human trait may be revised if the impetus is put not on apes' abilities to produce equivalents of words, but rather on their competence to comprehend language. (p.169)
For example, the language comprehension skills of the pygmy chimpanzee Kanzi (at age 8), has been systematically compared to those of a 2 year old child. Both subjects have been exposed to spoken English and to lexigrams from infancy. The two subjects are presented with the same sets of 660 novel sentences. Examples of sentences presented in English are "Put the milk in the water" or " Go get the raisins out of the refrigerator." It emerges from this comparison that the subjects can understand these novel requests with comparable accuracy. Their respective comprehension of English shows that they have mastered word recursion as well as the ability to reverse word order. From these data the authors infer that the potential for language comprehension probably preceded the appearance of speech in human evolution.
Several benefits can be expected from giving full membership to animal cognition in the cognitive sciences (which already includes neuroscience, cognitive psychology, philosophy, artificial intelligence, robotics, and linguistics). The main reason for including the study of animal cognition is that "to reach an integrated view of cognition, both developmental and evolutionary aspects are essential." Animal cognition contributes to the former, and is indeed crucial for the latter. (p.171)
Moreover, by studying cognitive processes in an ethological perspective, research on animals may shed light on the coupling between a cognitive system and its environment, thus introducing into cognitive science an ecological component that is still lacking. (p.171)
It is possible that the available data from comparative psychology may serve as a bedrock for a possible model of the human past....Further study of animal cognition should continue to help us to understand our own intelligence and its evolution. (p. 172)
Sue Savage-Rumbaugh (Apes, Language and the Human Mind, 1998)
Rumbaugh believes we need to get over feeling that we are superior.
Language is a funny thing. We do not think of it as behavior, yet at heart, that is all it really is--another form of behavior; a form that we use to characterize other parts of behavior, but a form that cannot be divorced from the rest of behavior.
There is nothing special about language, other than what it makes of itself. Language is a funny thing. It permits us to think that we know things that indeed we do not know. It permits us to talk about things rather than to do them and to think we have actually done something by talking rather than by acting. It permits us to think that by talking in unison, we can come to act in unison--forgetting that the more feeble the link between word and deed the less likely words are to alter deeds. Should we wish to act in unison, it is far better that we sing than that we speak.
Language is a funny thing. It permits us to thinks that other species are not able to communicate the purposes or intentions of their actions to one another, not to coordinate their behaviors, not to plan their actions. It permits us to think this because it permits us to avoid hearing the kind of talking that other species are doing.
Language is a funny thing. It enables man to put himself above the beasts simply by the act of saying to himself, "God gave man dominion over all the creatures that walk the land and all the fish that swim in the sea." What if we never said that to ourselves? (Pages 225-227)
Roger Fouts (Next of Kin, 1997)
Roger Fouts believes that animals do have souls based on his many conversations with Washoe over the years. He also believes that in this society there is a cultural mind set of "insiders" and "outsiders." [Note: Washoe died in 2009.]
Four decades ago, when we began locking chimpanzees away, we didn't know any better, but today we do. We know that chimpanzees are not mindless beasts but highly intelligent and inventive beings who have been transmitting complex cultures for millions of years. They are our evolutionary brothers and sisters. What are the moral implications of this scientific revelation?
It is a recurring fact of human history that we draw moral universes to include those who are like us and to exclude those who are unlike us. We grant certain rights and liberties to those inside our moral sphere, and we feel free to exploit those who stand outside. How do we determine who is an "insider" and who is an "outsider?" Historically, these distinctions have been based on bigotry, superstition, religious doctrine, cultural habit, legal precedent, or scientific "evidence"--and sometimes all of the above.
We like to think of science as the noble pursuit of objective knowledge, always marching forward in service to truth. But scientists embody the prejudices of their time. And scientists are far more dangerous than the average bigots because they can pass off ignorance as knowledge, and their "facts" can be used to erect and support moral boundaries. Unfortunately, as history has shown, when ignorance is married to arrogance the results are usually deadly for those outside a culture's moral universe.
In short, we are living by a moral code that is based on an arbitrary distinction between insiders and outsiders--in this case, two different species. This fact should trouble any person who believes that moral principles should be applied rationally and universally.
For example, we could expand our moral universe to encompass anyone capable of a certain kind of intelligence, self-awareness, family relations, and the capacity to suffer mental anguish. The fair application of these principles would immediately recognize all the great apes--chimpanzees, gorillas and orangutans--as belonging in our moral community because they have demonstrated all of these traits.
Charles Darwin understood this. He believed that our moral sense springs from our "social instinct" to care about others--an instinct we share with other animal species. At first we care only about those closest to us. But with time, we show concern for more and more of our fellow creatures. Our moral progress will not be complete, Darwin said, until we extend our compassion to people of all races, then to the "imbecile, the maimed, and other useless members of society;" and finally, to the members of all species. It is not surprising that the two practices of his time that Darwin detested more than all others were the enslavement of African Americans and cruelty to animals.
When Charles Darwin told us that we are related to apes we all woke up to a terrible nightmare: They are us. And in the hundred years since, we have wiped out millions of chimpanzees in a fury born of denial, arrogance, and self-interest. This fratricide is almost complete. And if we do not halt it now, then we will wake up one day soon only to discover that we've destroyed the living link to our own evolutionary past.
Washoe has been a constant reminder to me that humans do not travel upon this earth alone. For the past six million years, we have been accompanied on our journey by the biological and spiritual kin we call chimpanzees. (Pages. 368-385)
Epilogue
Many would say that all of this gibberish about animal abilities and much of the work poses a utopian model. As evidenced from the information, pioneers, research and evidence presented in this course, I would say that perhaps it may seem like a utopian model, but it really is not.
People with greater insights, who could probably be considered to be before their time (or at least more advanced thinkers than the masses of humankind), have been talking about this for at least a century and a half. We just have to bring people along.
