"The present work is the direct outcome of a series of lectures and demonstrations of neurological and mental examination methods which the author gave in a course to the interns of the Government Hospital for the Insane, first in 1910 and which has been repeated in subsequent years. It is also partly due to repeated suggestions that the scheme of examination published in the first edition of White's "Outlines of Psychiatry" (Chapter 7) be elaborated. The book is intended to place in the hands of psychiatrists, neurologists and students methods of examination which have been successfully used in psychological practice, to the end that the mental examination of patients may be conducted in a more systematic and scientific manner. An endeavor has been made to select methods which not only serve to show certain phases of mental processes, but which at the same time are easy to perform and are sufficiently accurate for certain kinds of research as well as for routine clinical purposes. All the methods which are described have been successfully used by the author from time to time, but it must not be assumed that each and every test may or must be applied to each and every patient who is to be examined. Alternative methods are often given because the author has found that one method can not be used with advantage with all kinds of patients"--Preface.
