Abstract:
Objective:To establish a foundation for the psychological selection of air combat personnel by studying the cognitive ability measurement methods for air combat personnel.Methods:The tests were done for 390 subjects including 142 radar operators, 117 radar academy students, 45 air combat personnel, and 86 radar trainees. Based on job analysis, 5 cognitive test tasks were developed, including graphic discrimination, working memory test, target tracking, voice anti-jamming, and comprehensive management. The discrimination was evaluated by the distribution graphs and coefficients of variation of the test results. The criterion-related validity was examined by correlating the cognitive test scores with the participants' work performance or academic grades, which served as the criteria. Content validity was determined by a 9-level scoring (1-9) of task necessity that collected from 30 air combat personnel and by the assessments of necessity of tested abilities that came from 30 experts. The parallel forms reliability, test-retest reliability and split-half reliability were tested respectively according to the results of each test.Results:The original scores of each test showed approximate normal distribution. The selected indicators' coefficients of variation were 14.4%-111.0%, reliabilities were 0.764-0.827, and criterion-related validities were 0.186-0.445, all of which were statistically significant (all P<0.05). In 30 air combat personnel, 53.3%-83.3% scored 7-9 to the necessity of test items, and 93.3% of 30 experts gave the required or basically required evaluations to the test items. Conclusions:The series tests show good content validity, and discrimination, reliability and the criterion-related validity meet the requirements of psychometrics. Especially the tests of graphic discrimination, working memory and target tracking expressed higher degree of discrimination, and can be used as cognitive ability assessment tool for the selection of air combat personnel.
