AN EXAMINATION OF AGE AND COGNITIVE TEST-PERFORMANCE ACROSS JOB COMPLEXITY AND OCCUPATIONAL TYPES

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 a 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.
