Study: IQ is related to focus (which is related to meditation)

A new study suggests that intelligence is more about what the brain chooses to ignore than simply its ability to process information rapidly, Time reports.

 

The research, which was published in the journal Current Biology, suggests new ways of testing intelligence that measure thought processes in ways that are less culturally biased than IQ tests and that can factor in those who process information differently.

 

Scientists led by Duje Tadin, assistant professor of brain and cognitive sciences at the University of Rochester, studied 67 people in two similar experiments that involved tracking the subtle movements of small and large objects on a computer screen. Intelligence correlated with their ability to tell which direction the balls moved and whether participants were better at tracking large or small balls. Those who tracked small balls did better on intelligence tests.

“For intelligence, you need to be able process relevant information fast, but you also need to focus on the most relevant information and filter out what’s irrelevant,” Tadin says.

Numerous other research studies have shown that meditation is a way to develop focus, to drop extraneous stimuli that may cause anxiety or stress. Can it also make you more intelligent? That study is down the road, I suppose.

But in the meantime ... a daily meditation practice won't hurt. Sit comfortably and quietly, focus on your breath. When you notice that your focus has moved to something else -- planning, remembering, evaluating, note that and return to your breath. Do that for a set amount of time.

Practice daily for weeks or months, and see if you feel smarter. Let me know.

More reason to teach mindfulness in schools

A study in the journal Psychological Science says that students who

had mindfulness training did better on the English portion of the GRE (graduate school entance exams) than those who didn't have it.

Forty-eight undergraduates were randomly assigned to either a mindfulness class or a nutrition class. Both classes met for 45 minutes, four times a week, for two weeks. During the mindfulness class, participants sat on cushions in a circle; they were asked to pay focused attention to some aspect of sensory experience, like the sounds of their own breathing. They practiced distinguishing between the simple thoughts that naturally arise in our minds (I have a test tomorrow) and the thoughts that become “elaborated” with emotion (I’m really worried that I won’t do well, and if I fail it, I’ll have to take the class over, and then I won’t graduate on time). The undergrads enrolled in the mindfulness class were taught how to reframe these more emotional concerns as mere “mental projections,” and how to allow their minds to rest naturally, rather than trying to suppress or get rid of their thoughts.

The results were clear: Participants who received mindfulness training showed improved accuracy on the GRE and higher working memory capacity, compared to those who received instruction in nutrition. Analyses indicated that the improvement could be explained, at least in part, by reduced mind wandering during the task.
The researchers estimated that mindfulness training resulted in the equivalent of a 16 percentile-point boost on the GRE, on average.

Study author Jonathan Schooler of the University of California theorizes that mindfulness may work by "dampening activation of the “default network,” a collection of regions in the brain that tend to become more active when our minds are at rest than when we’re focused on a mentally challenging task. Previous studies have found reduced activation on brain scans of meditators.

Schooler says this could have broad implications for learning: A number of recent studies have indicated that IQ can be increased through targeted interventions like this one, he says.

“The present demonstration that mindfulness training improves cognitive function and minimizes mind wandering suggests that enhanced attentional focus may be key to unlocking skills that were, until recently, viewed as immutable.”
