In 2011, researchers from the University of Wisconsin demonstrated that daily meditation-like thought could shift frontal brain activity toward a pattern that is associated with what cognitive scientists call positive, approach-oriented emotional states — states that make us more likely to engage the world rather than to withdraw from it.
Participants were instructed to relax with their eyes closed, focus on their breathing, and acknowledge and release any random thoughts that might arise. Then they had the option of receiving nine 30-minute meditation training sessions over the next five weeks. When they were tested a second time, their neural activation patterns had undergone a striking leftward shift in frontal asymmetry — even when their practice and training averaged only 5 to 16 minutes a day.
She also touches upon the myth of multitasking.
But mindfulness goes beyond improving emotion regulation. An exercise in mindfulness can also help with that plague of modern existence: multitasking. Of course, we would like to believe that our attention is infinite, but it isn’t. Multitasking is a persistent myth. What we really do is shift our attention rapidly from task to task. Two bad things happen as a result. We don’t devote as much attention to any one thing, and we sacrifice the quality of our attention. When we are mindful, some of that attentional flightiness disappears as if of its own accord.
