One-Page Summary
Robert Yerkes’s study of the mental life of monkeys and apes examines animal intelligence through behavior, learning, perception, problem-solving, and social interaction. Yerkes was a major early figure in comparative psychology, and the book reflects the period’s attempt to study animal minds systematically rather than relying entirely on anecdote. Experiments and observations are used to ask difficult questions: Can animals learn by experience? Do they solve problems through insight? How much of behavior is instinct, and how much is flexible adaptation? Modern comparative psychology has developed far beyond Yerkes’s methods and conclusions, but the historical importance remains.
The book records an early scientific effort to understand cognition across species and therefore to reconsider what makes human intelligence distinctive.
