"A work, the merits of which are likely to be underestimated because of its brevity, is 'An Outline of Educational Psychology,' by the late Rudolf Pitner of Columbia Teachers College; John J. Ryan, associate professor of education at Hunter College; Paul V. West, professor emeritus of education at New York University; and three other authors. Now in its fifth edition - a sign of its popularity-this book, pared down to bone-dry essentials, can serve a more useful purpose than do some works which are afflicted with expansiveness and verbosity. Its main sections deal with the history of educational psychology, the learning Process, tests and measurements, mental hygiene and character psychology, and the psychology of elementary and high-school subjects.”
