014 - III Acceptance of Methods by the War Department and early Modifications Resulting From Official use

When the United States entered World War I on April 6, 1917, a pioneering group of experimental psychologists came together to explore the potential of psychological services in the military. As their plans evolved, so too did the scope and responsibilities of their work. This report details the methods and outcomes of psychological examining within the U.S. Army. Divided into three parts, Part I presents the official history of the services development and operations during the war, complete with reproductions of original materials used. Part II offers a thorough overview of the preparation of methods, their distinctive features, and evaluations of their practical applications. Finally, Part III summarizes the results of the psychological examinations conducted. - Summary by Robert M. Yerkes
