‘Personality Genes’ May Help Account for Longevity

From the 24 May 2012 article at Science News Daily

It’s in their genes” is a common refrain from scientists when asked about factors that allow centenarians to reach age 100 and beyond. Up until now, research has focused on genetic variations that offer a physiological advantage such as high levels of HDL (“good”) cholesterol. But researchers at Albert Einstein College of Medicine and Ferkauf Graduate School of Psychology of Yeshiva University have found that personality traits like being outgoing, optimistic, easygoing, and enjoying laughter as well as staying engaged in activities may also be part of the longevity genes mix….

“When I started working with centenarians, I thought we’d find that they survived so long in part because they were mean and ornery,” said Nir Barzilai, M.D., the Ingeborg and Ira Leon Rennert Chair of Aging Research, director of Einstein’s Institute for Aging Research and co-corresponding author of the study. “But when we assessed the personalities of these 243 centenarians, we found qualities that clearly reflect a positive attitude towards life. Most were outgoing, optimistic and easygoing. They considered laughter an important part of life and had a large social network. They expressed emotions openly rather than bottling them up.” In addition, the centenarians had lower scores for displaying neurotic personality and higher scores for being conscientious compared with a representative sample of the U.S. population.

“Some evidence indicates that personality can change between the ages of 70 and 100, so we don’t know whether our centenarians have maintained their personality traits across their entire lifespans,” continued Dr. Barzilai. “Nevertheless, our findings suggest that centenarians share particular personality traits and that genetically-based aspects of personality may play an important role in achieving both good health and exceptional longevity.”..

How You Envision Others Says A Lot About You In Real Life

How You Envision Others Says A Lot About You In Real Life

From the 14 January 2012 Medical News Today item

Quick, come up with an imaginary co-worker.

Did you imagine someone who is positive, confident, and resourceful? Who rises to the occasion in times of trouble? If so, then chances are that you also display those traits in your own life, a new study finds.

University of Nebraska-Lincoln researchers have found that study participants who conjured positive imaginary co-workers contributed more in the actual workplace, both in job performance and going above and beyond their job descriptions to help others.

The results showed that your perceptions of others – even ones that are made up – says a lot about what kind of person you really are, said Peter Harms, UNL assistant professor of management and the study’s lead author. Imagining coworkers instead of reporting on how you perceive your actual coworkers produces more accurate ratings of having a positive worldview, he said, because it strips away the unique relational baggage that one may have with the people they know.

“When you make up imaginary peers, they are completely a product of how you see the world,” Harms said. “Because of that we can gain better insight into your perceptual biases. That tells us a lot about how you see the world, how you interpret events and what your expectations of others are.” ….
