问题    (1) It has long been believed that the smartphones in our pockets are actually making us dumber: but now there is evidence for it.
   (2) The constant presence of a mobile phone has a "brain drain" effect that significantly reduces people’s intelligence and attention spans, a study has found.
   (3) Researchers at the University of Texas discovered that people are worse at conducting tasks and remembering information if they have a smartphone within eye shot. In two experiments they found phones sitting on a desk or even in a pocket or handbag would distract users and lead to worse test scores even when it was set up not to disturb test subjects.
   (4) The effect was measurable even when the phones were switched off, and was worse for those who were deemed (认为) more dependent on their mobiles.
   (5) " Although these devices have immense potential to improve welfare, their persistent presence may come at a cognitive (认知的) cost," said Dr Adrian Ward, the lead author of the study. "Even when people are successful at maintaining sustained attention—as when avoiding the temptation to check their phones—the mere presence of these devices reduces available cognitive capability. "
   (6) The researchers tested 520 university students on their memory and intelligence when in the presence of a smartphone to see how it affected them.
   (7) Participants were told to complete tests in mathematics, memory and reasoning with their smartphones either on their desk, in their bag or pockets, or in another room, and with alerts turned off so as not to distract students.
   (8) Those who had their phones on the desk recorded a 10 percent lower score than those who left them in a different room on operational span tasks, which measures working memory and focus. Those who kept their phones further out of sight in their pockets or their bags scored only slightly better than when phones were placed on desks.
   (9) The researchers found that the negative effect of having a phone within eyeshot was significantly greater among those who said they were dependent on their smartphones. Participants who had expressed sympathy with phrases such as "I would have trouble getting through a normal day without my cellphone" and "using my cellphone makes me feel happy" performed as well as others when their phone was in a different room, but worse when it was placed on their desk.
   (10) The study also found reaction speeds to be affected, with students who had their phone on the desk responding more sluggishly in high-pace tests.
   (11) It even found that phones can even distract users even when they are turned off and placed face down. Those with phones outside of the room " slightly outperformed" those with switched off devices.
   (12) The researchers said the effect arises because part of a smartphone users’ mind is dedicated to trying to not think about distractions such as whether they have any messages when the handset (手机) is in their line of sight.
   (13) "We see a linear trend that suggests that as the smartphone becomes more noticeable, participants’ available cognitive capacity decreases," said Ward. "Your conscious mind isn’t thinking about your smartphone, but that process—the process of requiring yourself not to think about something—uses up some of your limited cognitive resources. It’s a brain drain. "
   (14) Similar research has previously showed smartphones can have a "butterfly brain effect" on users that can cause mental blunders. [br] Which of the following findings of the research is INCORRECT?
选项 A、Users addictive to smartphones were more adversely affected by visible phones.
B、The smartphone addicts with phones outside the room underperformed others.
C、Participants with their phones on the desk reacted more slowly.
D、Subjects’ attention is still diverted by the powered-off face-down phones.
答案 B
解析 推断题。原文第九段第一句提到，研究人员发现位于视野内的手机对那些自称依赖智能手机的人产生的负面影响明显更大，紧接着第二句对这一结论进行了具体的解释，该句指出曾对“没有手机我一天也熬不过去”和“玩手机让我感到很开心”等话语表示深有同感的测试对象，在其手机位于另一个房间时表现得和其他人一样好，但是当手机放在桌上时，则表现得比其他人差，由此可知，当手机在房间外面时，智能手机的依赖者们表现得和其他人一样好，而不是较差，B与原文表述不符，故为答案，同时排除A，A在原文直接提及。第十段提到研究还发现反应速度也受到手机影响，把手机放在桌上的学生在高节奏测试中的反应更为迟缓，C与原文表述相符，故排除；第十一段第一句指出研究甚至发现，即使手机已关机并且屏幕朝下放着，它们也能让使用者分心，由此可知，测试者们的注意力仍然会被已关机并且屏幕朝下放着的手机转移，故排除D。
