How many of a random string of numbers—say 1593657292759381380473—do you think you will be able to immediately remember? Some scientists say that you should be able to remember about seven of them. 【R1】__________
For the random numbers, you could for example remember it as one, five, nine, three. In this case, each individual number counts as a unit. 【R2】__________ So, when scientists say that you can keep a certain number of things in working memory, these individual things can be of varying size, complexity, and importance. Either way, working memory is small but really important.
What is working memory? Working memory is your brain’s dashboard. It’s the place you can temporarily put information while your brain decides whether or not it is worth the effort to put it somewhere more permanent, like your long-term memory.
As it turns out, different senses have different dashboard capacity. 【R3】__________Because of this, it is important to look at different types of working memory separately.
To make matters even more complicated, each and every person has a different ability to keep things in working memory. 【R4】__________
But, why are some people able to keep more in their working memory than others? New research by a team of scientists at Simon Eraser University has shed light on why some people may be able to keep more things on their brain dashboards than others. The research team, led by psychology professor John McDonald and doctoral student John Gaspar, learned about differences in visual memory by recording people’s brain waves and tracking how they paid attention.
Attention and memory are inextricably linked. By paying attention to an object, you increase its representation in the brain and make it easier to remember. But making something easier to remember is only one aspect of attention. Paying attention also means ignoring all of the distracting information in our world. 【R5】__________ According to John Gaspar, "This indicates that it might not be about how much relevant information you can remember but instead it might be about how good are you at ignoring irrelevant information."
This fit well with the scientists’ previous research, which had already demonstrated that the human brain has distinct processes for locking attention onto relevant information and for suppressing irrelevant information.
[A] However, these differences are not just about how much information people cram into their heads at once, but they’re also about how much people can keep out.
[B] These individual differences in working memory capacity are important because they have been shown to strongly predict things like intelligence; more working memory capacity generally equals more intelligence.
[C] More precisely, since a paper from the 1950s, called "The magical number seven, plus or minus two", some have suggested that the capacity of our working memory is typically somewhere between five and nine things—units or chunks of information.
[D] This means that how much you can remember seems to depend on whether, for example, someone says something to you or shows something to you.
[E] There are three separate stages of memory—sensory memory, short-term memory, and long-term memory—and the stage model of memory is often used to explain the basic structure and function of memory.
[F] However, you will be able to remember more of the number if you parse it differently; fifteen, ninety-three, sixty-five, seventy-two. Both of these count as four units, the information is just combined differently.
[G] And this is where people differ significantly. In the study, people who had low working memory capacities were unable to suppress important, distracting information.

C
解析
第一段开头提出一个问题:一串无规律的数字你能记住多少个?空格前指出某些科学家的答案,他们认为应该可以记住7个数字。空格后是第二段。该段前半部分仍就这串数字的例子展开讨论。因此,推测空格处的内容应该仍与记住这串数字相关。C引述了一篇名为“魔法数字7±2”的研究论文,指出大脑的工作记忆容量在5到9项信息之间,与空格前提到的科学家的观点构成顺承关系;此外,数字seven也起到了很好的提示作用。因此本题选C。
