The only correct response is "Bicycle." The most common error is _horse_ (or _donkey_), accounting for 48 out of 71 tabulated failures. Vehicles, like _wagon_, _buggy_, _automobile_, or _street car_, were mentioned in 14 out of 71 failures. Bizarre replies are: "A cripple in a wheel chair"; "A person riding on some one's back," etc. REMARKS. The experiment is a form of the completion test. Elements of a situation are given, out of which the entire situation is to be constructed. This phase of intelligence has already been discussed.[74] [74] See IX, 5, and XII, 4. While it is generally admitted that the underlying idea of this test is good, some have criticized Binet's selection of problems. Meumann thinks the lawyer element of the second is so unfamiliar to children as to render that part of the test unfair. Several "armchair" critics have mentioned the danger of nervous shock from the first problem. Bobertag throws out the test entirely and substitutes a completion test modeled after that of Ebbinghaus. Our own results are altogether favorable to the test. If it is used in year XIV, Meumann's objection hardly holds, for American children of that age do ordinarily know something about making wills. As for the danger of shock from the first problem, we have never once found the slightest evidence of this much-feared result. The subject always understands that the situation depicted is hypothetical, and so answers either in a matter-of-fact manner or with a laugh. The bicycle problem is our own invention. Binet used the other two and required both to be answered correctly. The test was located in year XII of the 1908 scale, and in year XV of the 1911 revision. Goddard and Kuhlmann retain it in the original location. The Stanford results of 1911, 1912, 1914, and 1915 agree in showing the test too difficult for year XII, even when only two out of three correct responses are required. If the original form of the experiment is used, it is exceedingly difficult for year XV. As here given it fits well at year XIV. XIV, 5. ARITHMETICAL REASONING PROCEDURE. The following problems, printed in clear type, are shown one at a time to the subject, who reads each problem aloud and (with the printed problem still before him) finds the answer without the use of pencil or paper. (a) _If a man's salary is $20 a week and he spends $14 a week, how long will it take him to save $300?_ (b) _If 2 pencils cost 5 cents, how many pencils can you buy for 50 cents?_ (c) _At 15 cents a yard, how much will 7 feet of cloth cost?_
