520    "In this research we have covered the data of four years of testing in the Vocational Bureau of Cincinnati. The results of two of these years are included in the Woolley and Fischer monograph, but we have limited ourselves in a number of ways. In the first place, our problem is more specific. We are interested in only one phase of the whole experiment, namely, the correlations between purely mental measurements, and their variations from year to year. In the second place, we have selected the records of boys only, and of those boys whose records were complete and continuous through the four years of testing. Thirdly, we have restricted ourselves to those tests which are called 'mental, ' paying no attention to such tests as seem to depend more on physical ability. Finally, we have paid little attention to tests which have not been carried on from year to year in much the same form. In other words, our emphasis was not on the variety of tests and a study of individual tests, but rather on the change in the various capacities measured by certain tests from year to year as indicated by their correlations"--Introduction.
