Project Gutenberg 2004-01-01 Public domain in the USA. 169 Yerkes, Robert Mearns 1876 1956 The Mental Life of Monkeys and Apes: A Study of Ideational Behavior Produced by Michael Oltz and PG Distributed Proofreaders "The Mental Life of Monkeys and Apes: A Study of Ideational Behavior" by Robert M. Yerkes is a scientific publication written in the early 20th century. The work focuses on the cognitive and behavioral processes of monkeys and apes, specifically investigating their ideational behavior—that is, the awareness and understanding they demonstrate in problem-solving scenarios. At the start of the publication, Yerkes outlines his aims of studying the adaptive behaviors of primates in a controlled environment in California. He discusses the facilities available to him, the animals he intends to study, and the methodology he plans to use, primarily revolving around a specially designed multiple-choice apparatus. These initial sections set the stage for a detailed exploration of primate intelligence, behavior, and emotional responses, suggesting that the text will not only present experimental results but also delve into the implications of these findings regarding animal cognition and the understanding of non-human intelligence.
