Abstract
The present study examined the predictive and incremental validity of three psychomotor ability measures (manual dexterity, finger dexterity, and motor coordination) in Canadian Forces personnel (n = 209) being trained in technical and mechanical occupations. For both types of occupations combined, manual dexterity predicted training performance (r =.18), as it did for the Technical (r = .22) and Mechanical (r = .17) families, separately. Finger Dexterity (r = .02) and Motor Coordination (r = .05) did not predict training performance for either the combined group or for each family by itself. The addition of the three psychomotor measures increased validity beyond what …
