Errors in the performance of repetitive or “boring” tasks—often attributed to a momentary lapse in concentration—can be serious in such activities as flying a passenger aircraft. Is there any method that would provide warning of such lapses—for example by monitoring brain activity? Researchers scanned the brains of volunteers performing a repetitive task. When the tasks were being performed correctly, the volunteers' brains showed activity in cognitive-processing regions. However, these regions became less active several seconds before some errors were made, and another brain region, region X, became active. The researchers concluded that the monitoring of region X could provide warning of an impending error.
Which of the following, if true, most supports the researchers' conclusion?
A. The cognitive effort required in performing a repetitive task diminishes significantly with increases in the number of repetitions of the task performance.
B. Once a mistake was made and detected, brain activity in regions associated with cognitive effort sometimes increased.
C. Other research found that whenever significant activity occurs in region X, it is generally with repetitive tasks, soon before an error occurs.
D. The diminution of brain activity in cognitive processing regions and the increase of activity in region X began at least 5 seconds before the errors occurred.
E. Reduced activity in brain regions associated with cognitive effort was accompanied by increased activity in regions that become active during sleep.
在执行重复性或“无聊”的任务时出现的错误——通常是由于一时的注意力不集中——在驾驶客机等活动中可能是很严重的。有什么方法可以为这些失误提供预警——例如通过监测大脑活动?研究人员扫描了从事重复性任务的志愿者的大脑。当任务被正确执行时,志愿者的大脑显示出认知处理区域的活动。然而,这些区域在出错前几秒钟变得不那么活跃,另一个大脑区域,X区域,变得活跃。研究人员得出结论,对X区域的监测可以为即将发生的错误提供预警。 下列哪项,如果是正确的,最能支持研究人员的结论? A.执行重复性任务所需的认知努力随着任务重复次数的增加而显著减少。 B一旦发现错误,大脑中与认知努力相关的区域的活动有时会增强。 C.其他研究发现,每当X区域发生重大活动时,通常是重复的任务,然后很快就会出现错误。 D.在错误发生前至少5秒,大脑认知处理区域的活动开始减少,X区域的活动开始增加。 E.与认知努力相关的大脑区域活动减少,同时睡眠时活跃的区域活动增加。
有没有大神说一下解题思路
