Not all failures in this test are equally significant. A bright child of 5 years sometimes fails, but usually not without many trial combinations which he rejects one after another as unsatisfactory. A dull child of the same age often stops after he has brought the pieces into any sort of juxtaposition, however absurd, and may be quite satisfied with his foolish effort. His mind is not fruitful and he lacks the power of auto-criticism. It would be well worth while to work out a new and somewhat more difficult "test of patience," but with special care to avoid the puzzling features of the usual games of anagrams. The one given us by Binet is rather easy for year V, though plainly somewhat too difficult for year IV. V, 6. THREE COMMISSIONS PROCEDURE. After getting up from the chair and moving with the child to the center of the room, say: "_Now, I want you to do something for me. Here's a key. I want you to put it on that chair over there; then I want you to shut (or open) that door, and then bring me the box which you see over there_ (pointing in turn to the objects designated). _Do you understand? Be sure to get it right. First, put the key on the chair, then shut_ (open) _the door, then bring me the box_ (again pointing). _Go ahead._" Stress the words _first_ and _then_ so as to emphasize the order in which the commissions are to be executed. Give the commissions always in the above order. Do not repeat the instructions again or give any further aid whatever, even by the direction of the gaze. If the child stops or hesitates it is never permissible to say: "_What next?_" Have the self-control to leave the child alone with his task. SCORING. _All three commissions must be executed and in the proper order._ Failure may result, therefore, either from leaving out one or more of the commands or from changing the order. The former is more often the case. REMARKS. Success depends first on the ability to comprehend the commands, and secondly, on the ability to hold them in mind. It is therefore a test of memory, though of a somewhat different kind from that involved in repeating digits or sentences. It is an excellent test, for it throws light on a kind of intelligence which is demanded in all occupations and in everyday life. A more difficult test of the same type ought to be worked out for a higher age level. Binet originally located this test in year VI, but in 1911 changed it to year VII. This is unfortunate, for the three Stanford investigations, as well as the statistics of all other investigators, show conclusively that it is easy enough for year V. V. ALTERNATIVE TEST: GIVING AGE PROCEDURE. The formula is simply, "_How old are you?_" The child of this age is, of course, not expected to know the date of his birthday, but merely how many years old he is.
