Discovering the etiology of problems arising in children which make them behave abnormally, or which obstruct the learning process offers greater difficulty than diagnosing some rare medical disorder. The problems may arise from varied sources. The difficulty may be due to some physical defect, to superior or defective intelligence, to a psychoneurosis, or to poor management. To arrive at a diagnosis necessitates careful inquiry from all angles. This book presents an outline of the methods to be used in studying problem children. While it would be impossible to adhere rigidly to the methods presented on all occasions, the book will make a satisfactory guide. It will be found useful to physicians, psychologists and social workers.
