Want to make your brain smarter? Then slow down

Want to make your brain smarter?

Slow down and dig deeper, advises Dr. Sandra Bond Chapman, a neuroscientist who has spent nearly 30 years studying this question.

It's not an easy prescription in a multitasking age, where the pinging of messages distracts your train of thought and schools reward rote memory. But Chapman's research shows that the brain's true growth occurs only when we focus, analyze and get those trains back on track.

Chapman, founder and chief director of the Center for BrainHealth of the University of Texas at Dallas, discusses her findings in her new book, "Make Your Brain Smarter: Increase Your Brain's Creativity, Energy and Focus" (Free Press, $26), written with Shelly Kirkland.

We talked to her about why frontal lobes are front and center in her research and what it means to be smart.

Q Is technology good or bad for our brains?

A There is some good to staying connected. The problem is that we're letting technology manage us more than we manage it. The more we keep ourselves in shallow, busy levels, the more our thinking gets fragmented, the more we are building a distracted brain that can't focus. We're building an ADD [attention-deficit disorder] brain. The frontal lobes require deeper-level thinking.

A Our frontal lobes pull together all the information from all the sources we have and help us figure out what to do with it. The frontal lobes have the most complex and vast connections across brain regions and are the last part of the brain to fully develop, usually in our 20s. But they are also the first to decline because, in our 40s, we tend to go on automatic pilot in our thinking.

Q Are you saying the frontal lobes don't have to decline?

A That's right. Our brains have neuroplasticity, which means that they are the most changeable part of our body. If I go on automatic pilot, I lose brainpower. But if I work the organ, it can get better every single year.

A lot of people have this idea that IQ is fixed and you're born smart or you're not. IQ was designed to see if kids had learning problems, to see their strengths and weaknesses. It was never meant to define the potential of the human mind or to say how far you're going to reach.

Q Does that mean that the frontal lobes don't automatically reach their potential?

If they're doing rote learning instead of using these deeper thinking skills, they may not build what they are supposed to build, which means that they may not end up with the discernment to make good judgments in other areas, as well.

Q What makes us smart?

A We tend to think that the smart person is the one who knows the most and retrieves the facts the quickest, but that's rote and rigid learning. You can create a robot that can do the same thing and in fact will surpass us. What really makes us smart is our ability to synthesize, abstract and process information.

Q What are the first steps we can take right now to build a smarter brain?

A Do one thing at a time and hyperfocus, instead of multitask. Try to think of two important things you do that have been on automatic pilot and repeated in the same way far too long and brainstorm ways to shake them up.
