Mentally challenging jobs may keep your mind sharp long after retirement

25.03.2014

A mentally demanding job may stress you out today but can provide important benefits after you retire, according to a new study.

"Based on data spanning 18 years, our study suggests that certain kinds of challenging jobs have the potential to enhance and protect workers' mental functioning in later life," said Gwenith Fisher, a faculty associate at the University of Michigan Institute for Social Research and assistant professor of psychology at Colorado State University.

The research analyzed data on 4,182 participants in the U-M Health and Retirement Study, which surveys a representative sample of more than 20,000 older Americans every two years.

Participants were interviewed about eight times between 1992 and 2010, starting when they were between the ages of 51 and 61. They worked in a wide variety of jobs and had been doing the same type of work for more than 25 years, on average, before they retired.

Fisher and colleagues examined the mental requirements of each job that participants reported having during that period. These requirements included analyzing data, developing objectives and strategies, making decisions, solving problems, evaluating information and thinking creatively.

They also assessed participants' mental functioning, using standard tests of episodic memory and mental status. The tests included recalling a list of 10 nouns immediately after seeing it and also after a time delay, and counting backwards from 100 by sevens.

In addition, the researchers controlled for participants' health, symptoms of depression, economic status and demographic characteristics, including years of education.

They found that people who had worked in jobs with greater mental demands were more likely to have better memories before they retired and more likely to have slower declines in memory after retiring than people who had worked in jobs with fewer mental demands.

The differences at the time of retirement were not large, but they grew over time.

"These results suggest that working in an occupation that requires a variety of mental processes may be beneficial to employees," said Jessica Faul, an ISR assistant research scientist.

"It's likely that being exposed to new experiences or more mentally complex job duties may benefit not only newer workers but more seasoned employees as well," she said. "Employers should strive to increase mental engagement at work and, if possible, outside of work as well, by emphasizing life-long learning activities."

The study did not establish causal relations between mental work demands and cognitive change after retirement, the researchers said, so it could be the case that people with higher levels of mental functioning picked jobs with more mental demands. But the study did control for formal education and income.

"What people do outside of work could also be a factor," Fisher said. "Some people may be very active in hobbies and other activities that are mentally stimulating and demanding, while others are not."

Fisher's research is published this month in the Journal of Occupational Health Psychology. The U-M Health and Retirement Study is primarily funded by the National Institute on Aging with additional funding provided by the Social Security Administration.

Im Focus: AchemAsia 2019 will take place in Shanghai

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...

Im Focus: Water is not the same as water

Water molecules exist in two different forms with almost identical physical properties. For the first time, researchers have succeeded in separating the two forms to show that they can exhibit different chemical reactivities. These results were reported by researchers from the University of Basel and their colleagues in Hamburg in the scientific journal Nature Communications.

From a chemical perspective, water is a molecule in which a single oxygen atom is linked to two hydrogen atoms. It is less well known that water exists in two...
