Cognitive Processes of Nonhuman Primates covers the proceedings of the Sixth Annual Symposium on Cognition, held at Carnegie-Mellon University on March 26 and 27, 1970. The symposium focuses on the status of research dealing with complex behavioral processes of monkeys and apes, providing insights into complex behavior of human and nonhuman primates. Composed of nine chapters, this book covers short-term memory in the monkey and how this relates to human short-term memory. A chapter compares memory deficits that accompany brain dysfunction in animals and man. The following chapters discuss the analysis of the development of language in a young female chimpanzee and the cogent analysis of interaction between habits and concepts in the monkey. The effects of early deprived and enriched environment on later complex behavioral processes of monkeys are also explained. Moreover, this book goes on examining the nonhuman brain capacities and the continuities with human behavior. It also discusses important research comparing delayed-response performance of several species of monkeys, age groups of children, and adults. The book will be of great help to scientists, researchers, teachers, and students who are interested in cognition processes and memory of nonhuman primates and humans.
