This study investigated age differences in the performance of a computer data entry task and the extent to which these differences were maintained with task experience. The study also identified abilities important to task performance. One hundred and ten participants from 3 age groups, younger (20-39 years), middle-aged (40-59 years), and older (60-75 years), performed the task for 3 days. Performance measures included a measure of quantity of work and measures of errors. The results indicated that the older people completed significantly less work than the middle-aged and younger people across all 3 days of the task. However, when controlling for differences in quantity of work, there were no age differences in errors. The data also indicated that visuomotor skills and memory were significant predictors of quantity and quality of work.
