(33)Researchers report that doing two or more things at once may decrease efficiency and actually take extra time switching from one task to another. In the most severe cases, it can even mean the difference between life and death.
In the study, four groups of young adults carried out a series of tasks and switched between different tasks, some complicated, such as solving math problems, and some more familiar, such as identifying geometric shapes. (34)The researchers found that time was lost in just switching from one task to another, and that time costs increased with the complexity of the tasks. “For each aspect of human performance—perceiving, thinking and acting people have specific mental resources whose effective use requires supervision through executive mental control,” said the lead author, David Meyer in materials provided with the report.
So-called“ multitasking” is becoming increasingly common because of cell phones and computers. the researchers point out, but it may just be adding wasted time and inefficiency to our days. A mere half second of time lost to task switching can mean the difference between life and death for a driver using a cell phone, Meyer said. (35)The authors say the research should make employers and employees think twice before implementing multitasking.
选项
A、They switched between different tasks with case.
B、They tended to get tired when they tried to multitask.
C、They got faster when they switched to familiar tasks.
D、They ultimately created more work for themselves.
答案
C
解析
推理判断题。根据问题.选项中They指的是“这项研究的受试者”。文章中间部分提到,研究人员发现变换工作浪费了许多时间,而且任务越复杂。转换浪费的时间越多。据此推测,如果参加实验者做自己较为熟悉的任务,所用的时间要少得多。因此答案为C)。
