As a simple, logical, authoritative, and fair minded introduction to psychology, this book could hardly be bettered. The author, who has studied and taught psychology in Europe, the United States, and New Zealand, approaches the study of human behavior from the starting point of our most primitive responses, the reflexes, which he explains simply in neurological terms. Illustrating his statements with concrete examples and with many instances from the most recent study of animal behavior, he goes on to discuss our basic drives and needs such as hunger, thirst, and the need for air, sleep, and security.
