Animal Intelligence: Experimental Studies replaces anecdote with controlled trials, charting how cats, chicks, dogs, and fish escape puzzle boxes and mazes. Using timed learning curves, Thorndike formulates the law of effect and law of exercise, arguing for trial-and-error stamping-in over insight or imitation. Its spare, tabular prose helped found comparative psychology, tempering Romanes's anthropomorphism and anticipating behaviorist method. Trained with William James and awarded his doctorate under J. McKeen Cattell at Columbia, Thorndike brought an educator's passion for measurement to animal study. Frustrated by anecdotal natural history and seeking general laws usable in classrooms, he devised cue-minimizing puzzle boxes and insisted on samples, controls, and objective records—an early expression of his connectionism, in which stimulus–response bonds strengthen or weaken with consequences. This classic remains methodologically bracing and conceptually fertile for readers in psychology, neuroscience, philosophy, and education. As both historical touchstone and primer in experimental design, Animal Intelligence rewards anyone curious how robust laws emerge from simple apparatus and careful records. Highly recommended to scholars of learning and practitioners of evidence-based training.
