Reading comprehension.

     In meditation (冥想), people sit quietly and focus their attention on their breath. As they breathe in and

out, they attend to their feelings. As thoughts go through their minds, they let them go. Breathe. Let go.

Breathe. Let go.

     According to a recent study at the Insight Meditation Society in Barre, Massachusetts, three months of

training in this kind of meditation causes a marked change in how the brain allocates attention. It appears

that the ability to let go thoughts that come into mind frees the brain to attend to more rapidly changing things

and events in the outside world. Expert mediators are better than other people at catching such fast-changing

stimuli, like facial expressions.

     The study provides evidence for changes in the workings of the brain with mental training. People can

learn and improve abilities of all sorts with practice, everything from driving to playing the piano. The study

has shown that meditation is good for the brain. It appears to reduce pressure and promote a sense of well-

being.

     In an experiment, 17 volunteers with no meditation experience in the experimental group spent three

months meditating 10 to 12 hours a day. A control group also with no meditation experience meditated for

20 minutes a day over the same period. Both groups were then given the tests with two numbers in a group

of letters. As both groups looked for the numbers, their brain activity was recorded.

     Everyone could catch the first number. But the brain recordings showed that the less experienced

mediators tended to grasp the first number and hang onto it, so they missed the second number. Those with

more experience gave less attention to the first number, as if letting it go, which led to an increased ability to

grasp the second number. This shows that attention can change with practice.

     Just ask Daniel Levision, who meditated for three months as part of the study. "I am a much better

listener," he said. "I do not get lost in my own personal reaction to what people are saying."
