Stanford-Binet “Indicators” of Mechanical Ability

tistical evaluation of the items in the Stanford Binet and, incidentally, of certain performance tests that might indicate the presence of mechanical ability. The theory that general intelligence and mechanical ability are distinct traits is consistently confirmed by the low correlations found between tests of intelligence and mechanical ability. Almost all of these studies are based on the total score or verbal "pencil and paper" type of intelligence test. Because of the variety of tests in the Stanford Binet, which presumably taps many functions, some might be sufficiently prognostic of the presence of mechanical ability
