Ii6 REPORT OF THE PSYCHOLOGY COMMITTEE 



haustlve series of tests for a considerable variety of naval 

 tasks based on an analysis of the tasks. This plan would 

 probably have been carried out to some degree at least, if 

 the armistice had not cut short our naval 'career.' 



"The connection between the subcommittee on vision and 

 the Listeners' School is not altogether clear even to myself. 

 But we were not fastidious in the selection of tasks provided 

 they would help win the war. 



"One of the minor but necessary tasks of the Training 

 Section of the Bureau of Navigation was to find properly 

 equipped men for the new Listeners' School without robbing 

 other training schools of their regular quotas. It was a rela- 

 tively simple problem in the economy of human material and 

 personnel, but one for which no data were available. At the 

 request of Captain Bennett, U. S. N., Chief of the Training 

 Section, I analyzed the requirements of the Listeners' School. 



"On the basis of that analysis, I elaborated a series of 

 tests for candidates for the Listeners' School and was sent to 

 various training stations to pick students from the enlisted 

 personnel. After correcting the tests from the school ex- 

 perience with the first few quotas, I was able to make a de- 

 tailed recommendation for the examination of candidates. 

 With the cordial assistance of Naval medical officers in the 

 several Districts, these tests afforded the Listeners' School a 

 selected student personnel from which 80 per cent, to 95 per 

 cent, of each class passed the course, all without seriously 

 affecting the supply of suitable men for other naval schools. 



"Without divulging anything that might be regarded as 

 a military secret, the general plan of the tests is indicated in 

 the following statement which has already been published by 

 authority of the Bureau of Navigation. 



I. Candidates for the Listeners' School were selected by the 

 following processes: 



{a) Their Navy record in the Training Station. 



{b) Their education (or other indication of intelligence). 



(c) A special medical examination. 



{d) A group elimination examination. 



(<f) An individual stethoscope test. 



(/) A final compensator test.
