Ageing, computer-based task performance, and stress: issues and challenges.

An emerging problem that encompasses both traditional ergonomic as well as macroergonomic concerns involves assessing the potential implications of computer-based tasks for older workers. An increasing older workforce and the influx of computer technology into a wide variety of work settings has motivated both a re-examination of the literature concerning ageing and work performance and research that more directly addresses the computer-interactive task domain. In this paper, we overview this literature and raise a number of crucial issues concerning potential age differences in performance and stress associated with computer-based tasks. Underlying our discussion throughout is the intention of identifying the challenges that await interested practitioners and researchers.

Age differences in the performance of computer-based work.

This study investigated the extent to which age had an impact on the performance of computer-based work. Three simulated real-world computer-interactive tasks that varied in complexity and pacing requirements were evaluated. Ss included 65 women, ranging in age from 25 years to 70 years. The methodology encompassed physiological, subjective, and objective performance measures. The data indicated that previous computer experience and age had a significant impact on the performance of the 3 tasks. Increased age was associated with longer response times and a greater number of errors for all 3 tasks. Age also influenced perceptions of fatigue and task difficulty. The findings are discussed in terms of the implications for training and job design.
