As we age, the brain‘s processing speed begins to slow, and memory may sometimes slip. But there are other ways that our mental powers grow as we get older. In the current issue of the journal Psychological Science, researchers report that older people (over 65) showed less variability in their cognitive performance across 100 days of testing than did younger people aged 20 to 31.
The older adults’ greater consistency “is due to learned strategies to solve the task, a constantly high motivation level, as well as a balanced daily routine and stable mood,” notes one of the scientists, Florian Schmiedek of the Max Planck Institute for Human Development in Germany. A colleague of Schmiedek’s, Axel Börsch-Supan, adds that his research shows that older workers are more productive and reliable, and less likely to make serious errors, than are their younger colleagues.
