Abstract : A study was conducted to investigate the nexus of cognitive and psychomotor tests as might be used for personnel selection and assessment. These domains are frequently seen as independent. A multiple aptitude cognitive test battery and a psychomotor test battery were administered to 354 United States Air Force recuits. The average multiple correlation of the cognitive tests and each psychomotor score as a criterion was 0.34, corrected for range restriction. Confirmatory factor analyses disclosed general cognitive and general psychomotor factors, three lower-order psychomotors, and two lower-order cognitive factors. The general cognitive factor accounted for 39% of the variance and the general psychomotor factor accounted for 29% of the variance. Residualized, the lower-order factors accounted for between 10% and 3% of the variance. The average g saturations (loadings) of the cognitive and psychomotor tests were 0.82 and 0.34, respectively. An implication for personnel selection is that the incremental validity of psychomotor tracking tests beyond the validity of cognitive tests will be small due to the commonality of measurement. A further implication of findings is the need to study the validity of the general and specific psychomotor factors.
