This book contains a simple and clear explanation of the basic psychological concepts and of some important psychological generalizations which undergraduate medical students, without previous psychological training, need to know for orientation in psychiatry and in clinical psychology. This is truly an introduction for it limits itself to the presentation of the fundamental ideas without going into details. On the contrary it gives a good bird's-eye-view of the interrelationship between individual and community, of intelligence and personality tests, of emotions and instincts, of psychoanalytic concepts, of the interdependence between constitution and personality, and of several psychological methods. The author took, out of psychology textbooks, concepts which the psychiatric student encounters in his studies. Adequate bibliographies follow each chapter. There are only a few lines about the psychology of the sick but it was not the author's purpose to discuss this subject. The book fulfills its own purpose very well.
