Industrial psychology now embraces a number of specialties. Realizing that no one psychologist has the depth of knowledge of each area of specialization to write a well-balanced text, we have here combined the resources of many. We have assembled the contributions of experimental, social, and clinical psychology, together with certain phases of business organization procedures, into a unified description of how modern psychology fits into the industrial complex.
The principal author invited fifteen specialists to work with him in preparing a completely up-to-date text based on a review of some fifteen thousand publications in the several areas. The contributors have from the beginning been keenly aware that a text written by several people would lack uniformity of style and organization unless one person took the responsibility of putting the entire manuscript into a single style. To achieve this the senior author has worked closely with each contributor in the writing and rewriting of the chapters. The final product is a uniform presentation.
Each contributor to this textbook was chosen for his knowledge of and involvement in a particular field. Some of the authors work full time in industry; most are college professors experienced in industrial consulting. Each contributor's name appears on the chapter he prepared. Eight chapters were written by the principal author; seven were written by other Carnegie professors; and six by other professional colleagues.
A comment on each author is in order. The chapter dealing with the development of industrial psychology was written by L. W. Ferguson of . . .
