Abstract
The test requires S to draw successive lines connecting serial numbers randomly arranged on a sheet of paper. A 50-number version of the test was given individually to 375 Chinese air cadets. Their time scores are practically normal in distribution, though somewhat positively skewed. Among those tested, 139 (37.07%) failed to graduate from the flying academy. When the cadets are classified into 8 groups according to a 1-min. class interval, the percentage of “wash-out” increases directly with their time scores. Since the test is of the paper-and-pencil type and can be used as an individual or a self-scoring group test, it is definitely more economical than the SAM Complex Coordinator or other elaborate, time-consuming individual apparatus tests currently employed in the selection of pilots.
