PSYCHOLOGICAL TESTS he must come down upon the clutch and foot brake. After each movement or response he is told always to come back to his original position, but in doing so he must not come down hard upon the accelerator. If he does this a mistake is registered. The apparatus is so devised that the signal lights are flashed automatically and remain lighted for a definite short interval of time. In order to be credited with a correct response, the subject must react with the appropriate movements within that given interval of time. If he makes incorrect movements or reacts too slowly, this response is not registered. On the other hand, if he is not careful and in his excitement strikes the accelerator, his mistake is registered automatically on an electric counter. The number of correct responses gives an index of his alertness and speed of reaction; the number of errors, a measure of his care- lessness. Throughout the test the subject’s responses and reac- tions are automatically recorded on electric counters which total each type of response separately. All that is necessary at the end of a test is to read off the figures from the several electric counters. The duration of this test is r 5 minutes (214, pp. 25-26). When tried on the drivers for a cab company in Pittsburgh, this test gave the following results. These figures refer to the €Iror score, a measure of carelessness (214). Those who passed the test (made fewer than 5 errors) aver- aged 1.3 accidents per man. Those who failed in the test (made 5 or more errors) aver- aged 3.0 accidents per man, Of those making no errors in the test, 53.0% had accidents. Of those making from 1 to 3 errors in the test, 81.2% had accidents. Of those making 4 or more errors in the test, 87.5% had accidents. Of those making no errors in the test, 54.6% were rated high- est in carefulness by superintendents. Of those making from 1 to 3 errors in the test, 31.25% were rated highest in carefulness. Of those making 4 or more errors in the test, none were rated highest in carefulness, Figures 7 and 8 are reproduced with the kind permission of Popular Science Monthly.
