There are certain phases of clinical psychology that are particularly concerned with medical problems; for example, those associated with intelligence and special abilities, behavior problems in children, and psychologic problems connected with various organic disabilities, such as speech, blindness, crippling and hearing. The author of this volume has had clinical experience in the University of Indiana at Bloomington and at the James Whitcomb Riley Hospital for Children in Indianapolis. His book reflects that experience as well as wide knowledge of the available literature in his field. By means of well selected case reports he reflects adequately the type of work that confronts the clinical psychologist today. Some of his records in the field of juvenile delinquency are particularly illuminating. The book is an excellent reference work in its field and should be helpful to all who are especially interested in the problems that it concerns.
