Principles of Training provides insight into the different variables presented by training tasks. It presents a wide sample of experimental data to reveal to the intending practitioner of training—whether in industry, in sport, in the defense services or other fields—that awareness of experimental findings must be paralleled by competence in analyzing tasks in order to determine how and where any particular principles may reasonably be applied. The book begins with an introductory chapter on the evaluation of training, experiments on training, limitations of training, and training problems. This is followed by separate chapters that discuss how trainers can influence the course of learning by manipulating knowledge of results; methods for minimizing errors in early learning; visual training methods; the use of words and actions in training; and the importance of practice in learning. Subsequent chapters cover the transfer of training; automatic teaching, or ""programmed instruction""; and recommendations for trainers.
