The personnel experiment with records of American Psychologists has proved remarkably successful from the standpoints of making studies of the present status of the science of psychology and of readily furnishing useful information in accordance with the policy of the Research Information Service. The practicability of the mechanism having been definitely established and its serviceability having been demonstrated to a limited clientele, it remains to extend the Service to those who are in a position to utilize the opportunity. By means of the Findex punch-card system, the records of American psychologists have been arranged to provide available information about different subjects of psychological inquiry. From the indexed personnel records it has been a simple task to determine the frequency of professional activity or interest in a given specialty. Similarly it has required only a few minutes' work to obtain evidence of the changes in activity at different periods. For various purposes the Findex method has proved both versatile and expeditious.

This method of exhibiting the trends of psychology contrasts in certain respects with efforts to measure degree of specialization and activity through classification of the literature for certain periods or through surveys of departmental and laboratory organization in academic institutions. An analysis of the activities of the individuals behind any movement probably offers the most promising method of evaluating its course and status. By this method preponderance of interest at present in practical phases of psychology is readily demonstrable. Change from speculative to experimental interest also is revealed. Demonstration of the frequency with which interests in psychology are combined with related fields of inquiry is another illustration of the use of the Findex file.

The use of terminology to designate specialties, even by the membership of the American Psychological Association, is in many instances quite inconsistent. There is indication of confusion in the designation of subdivisions of the field of psychology which have been roughly classified as branches, methods, and points of view. Terminology representing each of these classifications appears in the Year Book of the American Psychological Association as “subjects of research." As a result of this lack of precision in reporting subjects of research, the scatter of activities represented by American psychologists evidently appears greater than it should.
