Variations in cognitive, perceptual, and psychomotor abilities across the working life span: Examining the effects of race, sex, experience, education, and occupational type

Cognitive, perceptual, and psychomotor abilities were examined across the working life span for different racial groups, taking into consideration sex, job experience, education, and occupational type. Data included scores on all subtests of the General Aptitude Test Battery for White, Black, and Hispanic employees. Age and sex generally accounted for a relatively small percentage of the variance in ability test scores when experience, education, and occupational type were controlled. Race accounted for a substantial amount of variance in test performance, even after controlling for education, experience, occupational type, and age. Findings are discussed in terms of the potential for specific experiences and continuing education to affect the maintenance of abilities at later points in the life span for all racial groups.
