Culture Influences Brain Function

Been out for the holidays among other things but of interest on my return is a news release indicating that cultural bias can influence physiological brain function.  ScienceDaily, in this post, states that people from different cultures use their brains differently to solve the same visual perception tasks.  Using the binary cultural differentiation broadly characteristic of Eastern and Western cultures (emphasis upon the individual as opposed to emphasis upon the group), the study found that –

. . . the two groups showed different patterns of brain activation when performing these tasks. Americans, when making relative judgments that are typically harder for them, activated brain regions involved in attention-demanding mental tasks. They showed much less activation of these regions when making the more culturally familiar absolute judgments. East Asians showed the opposite tendency, engaging the brain’s attention system more for absolute judgments than for relative judgments. 

Making judgments outside of one’s cultural comfort zone involves more brain processing activity.  As one of the study authors suggests –

“Everyone uses the same attention machinery for more difficult cognitive tasks, but they are trained to use it in different ways, and it’s the culture that does the training,” Gabrieli says. “It’s fascinating that the way in which the brain responds to these simple drawings reflects, in a predictable way, how the individual thinks about independent or interdependent social relationships.”

Of related interest is the impact of culture on the brain’s mirror neuron system, the system that operates both when we do something as well as when we merely observe someone doing something.  It is this observation aspect that is significant as neuroscientists presently think that this “mirroring” is the neural mechanism by which people are able to empathize with others.

 A recent study indicates that mirror neuron activation increases when one is observing someone from one’s own cultural background as opposed to someone from a different cultural background, even when both are making the same culturally understood gestures.  “All in all, our research suggests that with mirror neurons our brain mirrors people, not simply actions,” this study’s author states. 

And that has interesting implications for empathy, group dynamics, communication, and other issues.

This idea that culture not only trains and influences how we behave, but actually impacts the physiological ways in which we use our brains is an interesting springboard for further exploring how we relate to one another, and more importantly, how we can develop better communication and coaching tools for the building of community.
