      都說眼睛是心靈的窗戶,或許,眼睛也是大腦的窗戶。一項(xiàng)研究表明,瞳孔大小或與智商水平高低有關(guān)。

      It has been said that “the eyes are the window to the soul”, but new research suggests that they may be a window to the brain as well.

      Our pupils (瞳孔) respond to more than just the light. They indicate arousal, interest or mental exhaustion. Pupil dilation (擴(kuò)張) is even used by the FBI to detect cheat. Now work conducted in our laboratory at the Georgia Institute of Technology suggests that baseline pupil size is closely related to individual differences in intelligence.

      The larger the pupils, the higher the intelligence, as measured by tests of reasoning, attention and memory. In fact, across three studies, we found that the difference in baseline pupil size between people who scored the highest on the cognitive tests and those who scored the lowest was large enough to be detected by the unaided eye.

      We conducted several largescale studies in which we recruited more than 500 people aged 18 to 35 from the Atlanta community. We measured participants pupil size using an eye tracker, a device that captures the reflection of light about the pupil and cornea (角膜) using a highpowered camera and computer.

      We measured participants pupils at rest while they stared at a blank computer screen for up to four minutes. All the while, the eye tracker was recording. Using the tracker, we then calculated each participants average pupil size.

      In the next part of the experiment, participants completed a series of cognitive tests designed to measure “fluid intelligence”, the capacity to reason through new problems, “working memory capacity”, the ability to remember information over a period of time, and “attention control”, the ability to focus attention amid distractions and interference.

      We found that a larger baseline pupil size was correlated with greater fluid intelligence, attention control and, to a lesser degree, working memory capacity—indicating a fascinating relationship between the brain and eyes.

      Interestingly, pupil size was negatively correlated with age: older participants tended to have smaller, more constricted pupils. Once standardized for age, however, the relationship between pupil size and cognitive ability remained.

      1. Why is the FBI mentioned in paragraph 2?

      A. The FBI responds to cheating quickly.

      B. Pupil dilation proves one is interesting.

      C. The FBI is good at finding people who cheat.

      D. Pupils change may give one person away.

      2. What can we infer from the three studies?

      A. Baseline pupil size hardly changes.

      B. An intelligent person has larger pupils.

      C. Those who scored the lowest were the old ones.

      D. Relationship between the brain and eyes is a puzzle.

      3. How were the largescale studies carried out?

      A. By inviting participants to have a long rest.

      B. By asking participants to finish a series of tests.

      C. By informing participants of their reaction to intelligence.

      D. By monitoring the participants brain activity while they were watching a computer.

      4. What does the last paragraph mainly talk about?

      A. Age affects pupil size.

      B. One becomes smarter when older.

      C. Older participants are cleverer.

      D. Pupil size becomes larger at an older

      age.
