"The last individual experiment was an association test. I called six words, like 'book,' 'house,' 'rain,' and had them speak the first word which came to their minds. The time was measured in fifths of a second only, with an ordinary stop-watch, as subtler experiments, for which hundredths of a second would have to be considered, were not needed.

Results of Experiments

"In studying the results, so far as the memory experiments were concerned, we found that it would be useless to consider the figures with more than ten digits. We took the results only of those with eight, nine and ten digits. There were fifty-four possibilities of mistakes. The smallest number of actual mistakes was two, the largest twenty-nine. In the experiment on attention made with the crossing-out of letters, we found that the smallest number of correctly marked letters was 107, the largest number in the six minutes, 272; the smallest number of overlooked letters was two, the largest 135; but this last case of abnormal carelessness stood quite isolated. On the whole, the number of overlooked letters fluctuated between five and sixty. If both results, those of the crossed-out and those of the overlooked letters, are brought into relations, we find that the best results were a case of 236 letters marked, with only two overlooked, and one of 257 marked, with four overlooked. The very interesting details as to the various types of attention which we see in the distribution of mistakes over the six minutes were not taken into our final table. The word experiments by which we tested the intelligence showed that no one was able to reproduce more than twenty-two of the twenty-four words. The smallest number of words remembered was seven.

"The mistakes in the perception of distances fluctuated between one and fourteen millimeters; the time for the sorting of the forty-eight cards, between thirty-five and fifty-eight seconds; the association-time for the six associated words taken together was between nine and twenty-one seconds. The pointing experiments could not be made use of in this first series, as it was found that quite a number of participants were unable to perform the act with the rapidity demanded.

"Several ways were open to make mathematical use of these results. I preferred the simplest way. I calculated the grade of the girls for each of these achievements. The same candidate who stood in the seventh place in the memory experiment was in the fifteenth place with reference to the number of letters marked, in the third place with reference to the letters overlooked, in the twenty-first place with reference to the number of word pairs which she had grasped, in the eleventh place with reference to the exactitude of space-perception, in the sixteenth place with reference to the association-time, and in the sixth place with reference to the time of sorting. As soon as we had all these independent grades, we calculated the average and in this way ultimately gained a common order of grading. * * *
