Catch yourself daydreaming while washing the dishes again? If this happens often you probably have a pretty capable working memory and a sharper brain, new research suggests.

This mind wandering, it seems, actually gives your working memory a workout. Working memory is the mental work space that allows the brain to juggle multiple thoughts at the same time. The more working memory a person has, the more daydreaming they can do without forgetting the task at hand.

Researchers studied groups of people from the University of Wisconsin－Madison community, ranging in age from 18 to 65. The volunteers were asked to perform simple tasks, like pressing a button every time they took a breath or clicking in response to a letter popping up on a computer screen; these tasks were so easy that their minds were likely to wander, the researchers figured.

The researchers checked in periodically, asking the participants if their minds were on task or wandering. When the task was over, they measured each participant's working memory capacity by having them remember letters while doing math questions. Though all participants performed well on the task, the researchers noticed that the individuals who indicated their minds had wandered more than others also scored higher on the working memory test.

“What this study seems to suggest is that, when circumstances for the task aren't very difficult, people who have additional working memory resources allocate them to think about things other than what they're doing，” said Jonathan Smallwood, a study researcher of the Max Planck Institute for Human Cognitve and Brain Science.

When our minds run out of working memory, these off－topic thoughts can take the main stage without us consciously meaning them to; for instance, arriving at home with no memory of the actual trip, or suddenly realizing that they've turned several pages in a book without understanding any of the words.

“It's almost like your attention was so absorbed in the mind wandering that there wasn't any left over to remember your goal to read，” study researcher Daniel Levinson, said in a statement.

People with overall higher working memory were better able to stay focused when the task at hand required it. Those who had low working memory often had their thoughts drift away from the task, and did less well at it.

The findings add to past research suggesting these mind drifts can be positive moments. For instance, daydreaming has often been associated with creativity—researchers think that our most creative and inventive moments come when daydreaming. It's likely that the most intelligent among us also have high levels of working memory, Levinson noted.

As the new term starts, freshmen around the world are asking the same question: how can I make the best of four years at college? The New York Times received suggestions recently from PhD students and seniors at some of the top universities . Here is their advice.

“Many young people today are raised in a protective cocoon(茧)”, wrote Tim Novikoff, a PhD student at Comell. “College is a time to explore the world beyond and a chance to learn new things about yourself. Take classes in different subjects. Try lots of different clubs and activities.”

Remember also to take some time away from campus, suggested Willie Lin, a student at Washington University. “If you spend all of your time in school, then it becomes too easy to let criticism from an unkind professor or a conflict with a roommate take up large proportions.”

Try to find work assisting a researcher or a professor---this is the advice from Aman Singh Gill, a PhD student at Stony Brook University. And he also said, “With a window into the world of research, you will find yourself thinking more critically, accepting fewer states at face value and perhaps developing a brave sense of what you can accomplish.”

Many young people can’t imagine even a single day without devices such as computers and cell phones. But try to keep yourself off them, cautioned Christine Smallwood, a PhD student at Columbia University.

Start by scheduling a few Internet-free hours each day, with your phone turned off. It’s the only way you’ll be able to read anything serious. “This will also have the benefit of making you harder to reach, and thus more mysterious and fascinating to new friends and acquaintances(熟人),” she suggested.

1.The underlined sentence in Paragraph 3 means we should _________.

A．spend more time at school                B．take some time out of school

C．listen to criticism more                   D．not argue with roommates

2.Who thinks it is important to consider something critically?

A．Aman Singh Gill                         B．Christine Smallwood

C．Tim Novikoff                           D．Willlie Lin

3.As for modern information devices, the last two paragraphs mean to tell us ________.

A．to keep ourselves off them forever not to use them

B．to turn them off

C．to make a schedule to use them

D．not to use them

4.This passage is mainly about _________.

A．tips from some students for college life

B．ways to read something serious regularly

C．days without cell-phones and computers

D．chances to go to university you really like
