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.”..

Excerpt from a summary of the report at Pew Internet (February 29, 2012)
Teens and young adults brought up from childhood with a continuous connection to each other and to information will be nimble, quick-acting multitaskers who count on the Internet as their external brain and who approach problems in a different way from their elders, according to a new survey of technology experts.
Many of the experts surveyed by Elon University’s Imagining the Internet Center and the Pew Internet Project said the effects of hyperconnectivity and the always-on lifestyles of young people will be mostly positive between now and 2020. But the experts in this survey also predicted this generation will exhibit a thirst for instant gratification and quick fixes, a loss of patience, and a lack of deep-thinking ability due to what one referred to as “fast-twitch wiring.”….

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.” ….

What are Job Candidates Really Like? Interview Techniques by an Industrial/Organizational Psychologist
Little things can be revealing in an interview, and a skilled interviewer can look beneath the surface to discover the real candidateBy Clif Boutelle, SIOP Public RelationsSelecting the right people to lead and build effective executive teams is critical to developing successful organizations, and the interviewing process can be the most important step.Hiring ineffective leaders can lead to a variety of negative outcomes for an organization, including diminished morale and business performance. That’s why companies will often turn to executive selection experts like Dean Stamoulis, who heads the Global Executive Assessment Practice for New York City-based Russell Reynolds Associates.He has conducted hundreds of interviews for top-level positions during the past 18 years. Employing his background in industrial-organizational psychology, he has the ability to delve beneath the superficial surface to determine the real substance and skills of candidates.“What you see is not always what you get, and that’s why it is important to be able to provide a full assessment of a candidate including traits and characteristics not readily apparent in an interview or with provided background information,” said Stamoulis, who is author of Senior Executive Assessment: A Key to Responsible Corporate Governance.He noted that too often interviewers become enamored with a charismatic candidate who makes a good first impression, instead of looking at relevant past performance and other indicators of leadership. It can work the other way as well. Some of the best executives do not make great first impressions. Looking deeper than the initial perception of a candidate can reveal skills needed for the position as well as leadership talents.“Many interviewers truly do not focus on the key elements needed for the position,” Stamoulis explained. “It’s not that hard, but a lot of people don’t do it.”One reason is that job descriptions are often too broad, he said. I-O psychologists can help organizations conduct a job assessment outlining the kind of skills needed for the position. They also possess the knowledge that can identify genuine leadership and personality traits of effective leaders and make valid predictions of likely success.What are some of the traits Stamoulis looks for in candidates? There are many, he says, but certainly breadth of knowledge and attention are important. A full and rich conversation covering different facets of the business, including both the historical and sociological elements, shows breadth about the business.

People in different cultures make different assumptions about the people around them, according to an upcoming study published inPsychological Science, a journal of the Association for Psychological Science. The researchers studied the brain waves of people with Caucasian and Asian backgrounds and found that cultural differences in how we think about other people are embedded deep in our minds. Cultural differences are evident very deep in the brain, challenging a commonsense notion that culture is skin deep.
Genes linked to the immune system can affect healthy people’s personality traits as well as the risk of developing mental illness and suicidal behaviour, reveals a thesis from the University of Gothenburg, Sweden.
Inflammation is part of the immune system and is responsible for defending humans against infection as well as fascilitating the healing of injuries, and is therefore vital for our survival. Research has demonstrated that inflammatory processes also have other roles to play as inflammatory substances produced by the body influence mechanisms in the brain involving learning and memory.
Inflammatory substances produced in moderate quantities in the brain can be beneficial during the formation of new brain cells, for example. However, an increase in the levels of these substances as is the case during illness, can result in damage to the brain.
“Previous studies have shown that individuals suffering from various mental illnesses have an increased peripheral inflammation, but the reason behind this increase is not known,” says Petra Suchankova Karlsson, who wrote the thesis. “It has been suggested that the stress that goes with mental illness activates the body’s immune system, but it is also possible that inflammation in the body affects the brain, which in turn results in mental illness.”
Previous studies have focused on how environmental and psychological factors affect the immune system’s impact on the brain. Suchankova’s thesis presents, for the first time, results that suggest that several different genes linked to the immune system are associated with healthy people’s personality traits. It also demonstrates that some of these genes are associated with an increased risk of developing schizophrenia or suicidal behaviour….

- Four out of the five principle personality “factors” as typically characterized by psychologists — conscientiousness, extraversion, neuroticism, agreeableness and openness/intellect — were associated with differences in regional brain mass
- Participants who described themselves as extroverted had a significantly larger medial orbitofrontol cortex — a part of the brain active in considering rewards. Perhaps not surprisingly, those self-described as conscientious had a bigger lateral prefrontal cortex
- Personality is not an immutable force, given that the brain grows and changes in reaction to experience
- Openness and intellect didn’t correspond to any particular brain structure
