学习时不要玩手机
Studying? Don't answer that text
学习中？别理那条短信
Cell phone use and texting are increasingly common, especially among teens. And that could be a problem. Texting affects learning and performing on tests, a new study finds. On average, students who responded to texts while working got lower scores. This trend held even for teens who felt they could multitask effectively.
手机的使用以及发短信变得日益普遍，尤其是在青少年中。这是一个严重的问题。新研究发现收发短信会影响学习及考试时正常水平的发挥，通常学生在学习时收发短信会导致低分。这一定义也适用于年轻人认为他们能有效率的兼顾多项工作这一情况。
Many students think that multitasking has no effect on how they perform in school, says Colter Norick, 17. (Multitasking is when a person tries to do more than one thing at the same time.) So the Montana teen and his 16-year-old brother Colin decided to test that notion.
许多学生认为多重任务不会影响他们在学校的表现，17岁的Colter Norick表示。（多重工作指的是一个人同时兼做多项事情）。因此蒙大拿州这一青年和他16岁的弟弟Colin打算对这一定义进行验证。
They recruited 47 classmates to take part in a two-phase experiment. The goal was to gauge how well these students understood written material. Each participant had to read a paragraph or two about a certain topic, then answer a question about it.
他们召集了47名同学来进行两个阶段的测试。目标是测评这些学生对书面材料理解程度。每个参与者都将针对一个特定的话题阅读一到两篇文章，然后根据文章回答问题。
In the first phase, the teen participants had 15 minutes to digest and then answer questions about six readings. Throughout this testing, the volunteers encountered no distractions.
在第一阶段，参与者用15分钟去理解并回答六篇阅读，整个测试过程中参与者无一分心。
A little later, Colter and Colin had their recruits tackle a new set of readings. This time, the brothers used a computer program to send texts to the volunteers' cell phones every 90 seconds. In each text, a fictional character named "Bob" asked questions that required a reply. One example: What's your favorite type of music?
然后Colter和Colin让他们的参与者开始进行下一轮的阅读测试，这次，两兄弟使用电脑程序给参与者的手机每隔90秒发一条信息，在该信息中，一个叫"Bob"的虚拟人物对参与者提出问题并要求回答，比如说他会问：你最喜欢什么类型的音乐？
Results were telling, the Norick brothers found. In theory, volunteers should have scored better, not worse, on the second test because it was slightly easier. In fact, the recruits scored 9 percent worse overall when distracted by incoming texts asking for some response. Only a few students scored as well when replying to texts as they did when undistracted. But importantly, Colter and Colin say, nobody performed better during the texting phase.
Colter和Colin的结果显示从理论上来讲，参与者本应该在第二次相对来说较容易的测试中取得更好而不是更糟的成绩，而事实上，当测试者收到要求回复的短信并被分散注意力时，他们的成绩整体下降了9%，只有几个人的成绩没有下滑，而他们也收到了短信，并没有分心。Colter和Colin表示最关键的是在短信测试过程中没有一个人的表现是更好的。
