Access to arts education is one of the civil rights issues of our time. I’d like to use brain science to explain why. Our brains operate using two types of behavior: automated and mediated. Automated behavior puts a premium on reliability and efficiency. The brain achieves this by pruning: It streamlines the neural circuitry required to complete a task. Automated behavior can be innate, like breathing, or learned, like recognizing the alphabet. Automated behavior is almost always unconscious. Throughout our lives, we develop and greatly rely on a host of automated skills. That’s why we don’t like backseat drivers – they force us to think about actions we’d prefer to remain unconscious.
We share the ability for automated mental behavior with all other animals. But as neuroscientist David Eagleman explains in his new book, Incognito, the human brain also has an advanced capacity for mediated behavior. The goal of mediated behavior is flexibility and innovation. Mediated behavior depends on multiple brain circuits working on the same problem – what Eagleman terms “the team of rivals.” Instead of dedicating a limited neural network to a task, the brain tolerates redundancy and promotes networking. It’s what we mean by “keeping an open mind.” Mediated behavior can also involve conscious awareness: We overhear and participate in the internal conversation of our thoughts. The vigorousness of our mediated behavior is unique in the animal kingdom. It is what defines us as human beings.
