Your Social Brain

Your Social Brain: Your Way to a Bigger, Better Brain

What happens to your brain if you are not actively involved with other people and lead an isolated lifestyle? Sorry – not a good lifestyle choice for your brain. Your brain needs interaction with other people. There are so many different areas of your brain that are involved in interaction with other people, it gets a real workout. Is this revelation about brain function and socialization just an anecdotal supposition or is it the real deal?

Studies on Socialization

There have been studies on the effect of socialization and the brain. The University of Michigan published a study in February of 2008 that demonstrated that talking with another person for just 10 minutes every day could improve memory and mental performance. The study was large with over 3600 participants ranging in ages 24-96 years old. All age groups received a variety of baseline tests and then interacted with others throughout the study period. The findings revealed that the higher the level of social interactions, the better their cognitive functioning was. These findings applied to all age groups.

There was a second experiment performed at the University of Michigan. This study looked at social versus intellectual activities. The participants were college students. What the researchers found was that short-term social interaction for 10 minutes boosted the participant’s intellectual performance as much as engaging in intellectual activities for the same amount of time. This study demonstrated the causal evidence that showed social interaction directly affects memory and mental performance in a positive way.

Laura Carstensen, professor and the founding director of the Stanford Center on Longevity said that the social arena “influences not only our happiness in everyday life but the ways in which our brains process information, the levels of hormones circulating in our bodies and our psychological response to stress”. That is a lot of action for just interacting with other people.

And finally, the MacArthur Study of Successful Aging found that people who are socially connected may live up to 20% longer than those who live a more isolated lifestyle. More social interaction is associated with lower blood levels of cortisol (stress hormone) and better cognitive health (Rowe & Kahn, 1998).

One more socialization study looked at three groups of people assigned different tasks for ten weeks. Prior to the study, all participants were given cognitive testing to determine their cognitive baselines. The study required the participants to come to the testing location three times a week for an hour each day. The participants were separated into three groups: group one was not given any specific instructions – other than to show up. Group two were assigned to do online brain games for the ten weeks. Group three was told to interact with the other people in their group. They were supposed to learn all about each other over the ten-week span. At the end of the study all participants were again given cognitive testing to determine any changes. As it turns out – group three – the socialization group – scored the highest results – even over the online game-training (mental stimulation) group. When you interact with other people you develop better cognitive skills. Throughout the ten-week period, this group was developing brain resilience – making their brains stronger.

We are hardwired to connect

Socialization is critical to brain health. There are certain groups of people that are more vulnerable to isolation issues that can prove to be a risk to brain health. Seniors who are aging in place in their homes often live by themselves. Unless they have connections to outside community activities, events and people, they are at a high risk of developing depression and dementia. The brain really needs other people. Retirees are vulnerable to social isolation. The workplace is a novel and challenging environment with coworkers around with which to interact. After retirement, unless there is a plan to replace that network with a similar social experience, there is a risk of developing depression. Finally, there are employees who work at home. This is convenient but can be socially isolating. In order to keep at-home workers engaged and motivated it is important for group events and onsite meetings to take place so that the employee can still feel connected.

We have the advantage of technology to help us stay connected. It seems that talking over the phone is good but using Skype or FaceTime to have a conversation is even better. Our brain uses many areas and functions when we see the person we are talking to. This whole brain workout from seeing the person you are talking to is valuable. Although there may be many of us who haven’t used our video capabilities while talking, it is important not to be intimidated by the technology. It is not difficult if you understand how it works. So call one of your kids or grandkids and let them set it up for you and then teach you how it all works. If you don’t have family nearby, the phone stores are all capable of teaching you how to use your options on your phone or other mobile devices

Blue Zones

In his best seller book, Blue Zones (2008), Dan Buettner and his researchers described groups of people around the world where the people are living longer and better lives. The Blue Zones are enriched environments that supported healthy eating and exercise, cognitive and social stimulation, and purposeful life. Following are a list of practices that contribute to an enriched social environment:

• Committing and connecting daily with family and friends.

• Engaging actively in group activities.

• Re-careering.

• Seeking intergenerational connections.

• Developing a sense of purpose and living it out.

• Pushing yourself to try new relationships and to learn new skills.

• Going back to school.

• Building social capital.

• Rotating your crops!

(Buettner, 2008)

For a fuller, happy life that does wonders for your brain, get out and be with other people. Your brain will light up with the stimulation.
