Psychological test performance of steel industry production supervisors

Abstract

The job success of 33 production supervisors in a large steel-manufacturing concern was independently rated by the plant superintendent and two assistants using a paired-comparison rating technique. The 10 supervisors rated highest and the 10 rated lowest were given a 7-hour battery of 10 tests of intelligence, mechanical ability, personality, and interest. Differences in test scores between the "high" and "low" groups of supervisors were studied. It was found that the California Short Form Test of Mental Maturity , the Survey of Space Relations , and the Adaptability Test differentiated between the "high" and "low" supervisors at the 1% level. The Mechanical Comprehension Test , 2 scales on the Bernreuter Personality Inventory , and 2 scales on the Strong Vocational Interest Blank distinguished between the 2 groups of supervisors at the 5% level.
