A majority of the world's significant schools of psychology are thus represented. The series constitutes a unique and significant cross-section of the theoretical bases of contemporary psychology. Here are the norms with which later the Psychologies Of 1935 or the Psychologies Of 1950 can be directly compared. This book is highly suitable for use as a text-book in advanced courses in general or theoretical psychology. The volume contains a full-page half-tone of each author in the series, each one being inserted at the proper place in the volume. Approximately five hundred pages of solid ten-point type, 4 by 6.5.
