A study undertaken at Berlin’s Max Planck Institute for Human Development compared the consistency of workplace performance and reliability of older workers aged 65 to 80 years old with younger workers aged 20 – 31 years old.
The testing took place over 100 consecutive days and 12 repeated tasks measured perception, episodic memory (remembering things from the past) and working memory (short term memory).
The results showed that the older age group demonstrated levels of productivity and reliability that were higher than the younger age group. This was attributed to them having learned strategies to solve tasks and balance their routines, while maintaining consistent motivation and a stable mood.
This is a significant finding which supports the need for companies to develop policies that support the retention of older workers.
