Can a parrot understand complex concepts and mean what it says? Since the early 1900s, most studies on animal-human communication have focused on great apes and a few cetacean species. Birds were rarely used in similar studies on the grounds that they were merely talented mimics--that they were, after all, "birdbrains." Experiments performed primarily on pigeons in Skinner boxes demonstrated capacities inferior to those of mammals; these results were thought to reflect the capacities of all birds, despite evidence suggesting that species such as jays, crows, and parrots might be capable of more impressive cognitive feats.
Twenty years ago Irene Pepperberg set out to discover whether the results of the pigeon studies necessarily meant that other birds--particularly the large-brained, highly social parrots--were incapable of mastering complex cognitive concepts and the rudiments of referential speech. Her investigation and the bird at its center--a male Grey parrot named Alex--have since become almost as well known as their primate equivalents and no less a subject of fierce debate in the field of animal cognition. This book represents the long-awaited synthesis of the studies constituting one of the landmark experiments in modern comparative psychology.
Animal Cognition presents a clear, concise, and comprehensive overview of what we know about cognitive processes in animals. Focusing mainly on what has been learned from experimental research, Vauclair presents a wide-ranging review of studies of many kinds of animals--bees and wasps, cats and dogs, dolphins and sea otters, pigeons and titmice, baboons, chimpanzees, vervet monkeys, and Japanese macaques. He also offers a novel discussion of the ways Piaget's theory of cognitive development and Piagetian concepts may be used to develop models for the study of animal cognition.
Individual chapters review the current state of our knowledge about specific kinds of cognition in animals: tool use and spatial and temporal representations; social cognition--how animals manage their relational life and the cognitive organization that sustains social behaviors; representation, communication, and language; and imitation, self-recognition, and the theory of mind--what animals know about themselves. The book closes with Vauclair's "agenda for comparative cognition." Here he examines the relationship of the experimental approach to other fields and methods of inquiry, such as cognitive ethology and the ecological approach to species comparisons. It is here, too, that Vauclair addresses the key issue of continuity, or its absence, between animal and human cognition.
Given our still limited knowledge of cognitive systems in animals, Vauclair argues, researchers should be less concerned with the "why" question--the evolutionary or ecological explanations for differences in cognition between the species--and more concerned with the "what"--the careful work that is needed to increase our understanding of similarities and differences in cognitive processes. This thoughtful and lively book will be of great value to students of animal behavior and to anyone who desires a better understanding of humankind's relations to other living creatures.
Merging evolutionary ecology and cognitive science, cognitive ecology investigates how animal interactions with natural habitats shape cognitive systems, and how constraints on nervous systems limit or bias animal behavior. Research in cognitive ecology has expanded rapidly in the past decade, and this second volume builds on the foundations laid out in the first, published in 1998.
Cognitive Ecology II integrates numerous scientific disciplines to analyze the ecology and evolution of animal cognition. The contributors cover the mechanisms, ecology, and evolution of learning and memory, including detailed analyses of bee neurobiology, bird song, and spatial learning. They also explore decision making, with mechanistic analyses of reproductive behavior in voles, escape hatching by frog embryos, and predation in the auditory domain of bats and eared insects. Finally, they consider social cognition, focusing on alarm calls and the factors determining social learning strategies of corvids, fish, and mammals.
With cognitive ecology ascending to its rightful place in behavioral and evolutionary research, this volume captures the promise that has been realized in the past decade and looks forward to new research prospects.
Understanding the chimpanzee mind is akin to opening a window onto human consciousness. Many of our complex cognitive processes have origins that can be seen in the way that chimpanzees think, learn, and behave. The Mind of the Chimpanzee brings together scores of prominent scientists from around the world to share the most recent research into what goes on inside the mind of our closest living relative.
Intertwining a range of topics—including imitation, tool use, face recognition, culture, cooperation, and reconciliation—with critical commentaries on conservation and welfare, the collection aims to understand how chimpanzees learn, think, and feel, so that researchers can not only gain insight into the origins of human cognition, but also crystallize collective efforts to protect wild chimpanzee populations and ensure appropriate care in captive settings. With a breadth of material on cognition and culture from the lab and the field, The Mind of the Chimpanzee is a first-rate synthesis of contemporary studies of these fascinating mammals that will appeal to all those interested in animal minds and what we can learn from them.
