About the Author

Dorothy Leavitt Cheney was born in Boston, Massachusetts on August 24, 1950. She received a bachelor's degree in political science from Wellesley College in 1972 and a Ph.D. in zoology from Cambridge University in 1977. She taught at Rockefeller University, the University of California, Los mostrar mais Angeles, and the University of Pennsylvania. She and her husband and research partner Robert M. Seyfarth studied gorillas, baboons, and vervet monkeys in Africa. They wrote several books including How Monkeys See the World: Inside the Mind of Another Species and Baboon Metaphysics: The Evolution of a Social Mind. She died from breast cancer on November 9, 2018 at the age of 68. (Bowker Author Biography) mostrar menos

An examination of primate cognition based on findings from the authors' decade-long field project studying vervet monkeys in Kenya, as well as the work of other primatologists both in lab experiments and other field studies.

The book systematically develops its ideas, first examining monkeys' social knowledge and communication, then delving into other areas such as deception, attribution of mental states to others, and nonsocial intelligence. The authors describe how vervet monkeys have quite well-developed social abilities, including a detailed understanding of the social relationships among members of their group and the ability to refer to external objects (such as dangerous predator species) through different types of vocalization. However, they present other evidence that suggests that monkeys may lack the ability to reflect on their own knowledge, attribute mental states to others, or apply social intelligence to other domains.

The authors' work combined field observation with ingenious audio playback experiments to investigate monkeys' knowledge and understanding of the world through their behavior in a natural setting. In addition the book cites the work of numerous other researchers to augment the authors' own findings and compare the abilities of different primate species. This gives the ideas in the book a strong scientific basis.

The book's writing is lucid but quite dense, so it may be challenging for those who are unused to reading scientific literature. However, for readers interested in primate cognition, this book provides a fascinating examination of the topic.

Cheney and Seyfarth started research on vervet monkeys as post doctoral fellows of Rockefeller University, an interest that was to lead to 13 years (1977-1990) of field work in the Amboseli National Park of Kenya and eventually this book.
The question is "How do monkeys see the world?" and the interesting answer of Cheney and Seyforth is that monkeys see and learn that A leads to B but don't know why. As they say,"An individual who cannot reflect upon his own knowledge to form hypotheses about what he knows, will almost by definition be unable to extend knowledge from one context to another".

This basic fact accounts for the lack of teaching of young monkeys. They have to learn by observation that A leads to B. The adult doesn't know that it knows anything so it is not surprising that it doesn't do any teaching. Monkeys live in a world of action and reaction without an understanding of what is happening.

Cheney and Seyfarth note that at least 70% of the deaths of vervet monkeys in Amboseli are from predation and that frequent predators are leopards and pythons.
Consequently reactions to different alarm calls are tailored to meet the threat (leopard- run for a tree, python- stand on back legs and look around), but secondary signals indicating leopards or pythons that are clear to humans are lost to the vervets. They can't make a mental picture of the behavior of leopards or pythons and consequently fail to see the danger of a recent leopard kill (leopards nearby) or a fresh python track leading into a bush. They were observed on occasion to walk straight into the bush despite a very clear and fresh track indicating that the snake was there.
Their conclusion is mirrored in human development, where it is only at the relatively late age of 4-6 years that children can imagine another persons point of view (i.e. think in the abstract). This is shown in the important experiment by Wimmer and Penner (page 207) and seems to indicate that this is the developmental stage where monkeys and humans part company.

In my opinion this is a very valuable book, especially as the work was done over such along period and in the animals natural environment.
