These in Vestigations were carried out under the kind advices of the late Dr. Koreshige Masuda.
Subjects were fifty eight Soldiers. some of them were already recognized as the well-fitted reporters according to the selected method applied up to this time, and the others were selected at ramdom by fives and sevens from each company.
In the first investigation, seven tests were employed. They were as follows:
Test 1. A test of the direct memory of tones. Test 2. A test of the direct memory of figures. Test 3. A test of the the writing speed. Test 4. A test of the direct memory of simple forms. Test 5. A test of the repeating of commands. Test 6. A displacement test. Test 7. An addition test.
The total sum of full marks of these seven tests is 105. According to the results of tests, the best subject got marks of 80.3, and the worst one marks of 6.8.
Seven months later the second investigation was carried out. In this investigation, the test of the direct memory of forms and the addition test were omitted from the list of tests employed in the first investigation. In this case, therefore, the number of tests is five and the total sum of full marks of five tests is 100.
Now, if we examine the results according to the coefficients of correlation between the work of communication and the result of tests, we may enumerate the following discoveries :
(1)A coefficient of the total sum of marks is+0.4872 and ±0.0917,and that of test 5 is+0.4872 and±0.0917,of test 6,+0.4464 and ±0.0959,of test 7,+0.4261 and ±0.0979,oftest 1,+0.3748 and ±0.1024,of test 3,+0.2714 and ±0.1097, of test4,+0.1360 and ±0.1157, and of test2,+0.942 and±0.1167. Consequently, the test of repeating the commands, the displacement test and the addition test have more relation with the selection of the reporters than the test of direct memory of the figures and forms.
(2) The order of arrangement of the coeflicients with the results of reporting work is the sound morus (+0.6180),±0.1165), the flag morus (+0.5881, ±0.0794), the light morus (+0.4771,±0.1161), the composition of communication (+0.3748, ±0.1024), the flag signal (+0.3542, ±0.1166), the school knowledge (+0.2195, ±0.1125) and the telephone (+0.1465, ±0.1154). Namely, the correlation of the reporting work is higher .with the morus signs of either sound or flag and the like than with knowledge or technique.
(3) In either case, the reporter with more sensibility in the auditory sensation than in the visual shows more satisfactory result. Accordingly, man had better choose the auditory type.
(4) The coefficient of total sum of marks is +0.7217, ±0.0590. And the test 3 (+0.6428, ±0.0709) comes first. Next the test 1 (+0.5794, ±0.0846), the test 6 (+0.4669, ±0.0938), the test 5 (+0.3748, ±0.1024) and the test 4 (+0.3439, ±0.1048) follow. In this case, too, the correlation is high in the test of the writing speed, the direct memory of tones and the displacement, and low in the test of the direct memory of figures in which the visual sensation plays a principal role.
(5) The coefficients of the communicating work with each test are arranged in order as follows : the flag morus sign (+0.6873, ±0.0648), the Sound morus sign (+0.6478, ±0.0709), the light morus sign (+0.5075,±0.0893) and the flag signal (+0.5075,±0.0893). We can see here the high correlation with the employment of the morus signs again.
(6) The coefficients of correlation between the result of the first investigation and that of the second are +0.7943and ±0.0460; these numbers, of course, swill be different according to the kinds tests.
