An examination of age and cognitive test performance across job complexity and occupational types
Article Abstract:
In this study, job complexity and occupational type were examined as potential moderators of the relationship between age and cognitive ability. Data included general, verbal, and numerical ability scores for 21,646 individuals in the General Aptitude Test Battery (GATB) data base. These individuals comprised 102 unique samples and 10 major occupational groups. Differences in the relationship between age and cognitive ability test scores were observed across occupational types but not for different levels of job complexity. Findings were discussed in terms of need for research that examines specific life and work experiences and how such experiences may influence an individual's cognitive abilities across the life span.

Homogeneity of test validity
Article Abstract:
In this present investigation we examined the extent to which the validity of three cognitive ability tests varied across test score range with respect to predicting job performance. This study was a partial replication and extension of Lee and Foley (1986). The 24,219 participants in the current study were obtained from the General Aptitude Test Battery (GATB) data base. Measures included in the analyses were general cognitive ability, numerical ability, and verbal ability. Results did not confirm Lee and Foley's findings. Specifically, the validity of tests used in this study did not appreciably vary at different points along the test score range. (Reprinted by permission of the publisher.)

A meta-analysis of age differences in job performance
Article Abstract:
An analysis of 40 samples is made to determine correlation between age and job performance. The samples were split into three groups, based upon how they were evaluated: supervisory ratings, peer ratings and individual productivity. On productivity ratings, performance improved with age, yet supervisory ratings declined slightly with age. There were other unexplained variances among the evaluation methods. The study also found correlations between professional and nonprofessional jobs. Performance ratings were most positive for professionals.
