Age differences in perception of workload for a computer task

Research concerned with age and work activities is an important area of investigation since the workforce is aging and there are concerns regarding economic dependency as well as labor shortages for certain occupations. Previous work by the research team indicated age differences in the performance and perceptions of task difficulty and fatigue for three simulated real-world computer tasks. This study is an extension of that research and is investigating the extent to which age differences in performance and perceptions of workload are moderated by experience and task practice. One hundred and twenty subjects aged 25 yrs. to 75 yrs. performed a real-world data entry task. Data will be presented regarding age differences in the perception of workload, stress, discomfort, and attitudes towards computers. The implications of these results for design interventions will be discussed.
