People with bigger brains ftend to score higher on standardized tests of intelligence, according to new study findings.
However, the study author Dr Michael A.McDaniel of the Virginia Commonwealth University in Richmond emphasized that these findings represent a general trend, and people with small heads should not automatically believe they are less intelligent. For instance, Albert Einstein’s brain was “not particularly large”, McDaniel noted. “There’s some relationship between brain size and intelligence on the average, but there’s plenty of room for exceptions,” he said.
Interest in the relationship between brain size and intelligence grew in the1830s, when German anatomist(解剖学家) Frederich Tiedmann wrote that he believed there was “an unquestionable connection between the size of the brain and the mental energy displayed by the individual man”. Since that statement, scientists have conducted numerous studies to determine if Tiedmann’s assertion was, in fact, correct. Most studies have looked into the link between head size and intelligence. More recently, however, researchers have published additional studies on brain size and intelligence, measured using MRI scan(核磁共振成像扫描).
For his study, McDaniel analyzed more than 20 studies that looked into the relationship between brain size and intelligence in a total of 1,530 people. The studies showed that on the average, people with larger brain volume tended to be more intelligent. The relationship between brain volume and intelligence was stronger in women than men, and in adults than in children. McDaniel notes in the journal Intelligence.
McDaniel is not sure why the relationship was stronger for adults and women. “Other research has shown that women, on the average, tend to have smaller brains than men, but score just as well—if not higher—in tests of intelligence,” he said.
McDaniel insisted that the relationship between brain size and intelligence is not a “perfect” one. “One can certainly find lots of examples of smaller-sized people who are highly intelligent,” he said, “But, on the average, the relationship holds.”

请阅读下面一篇文章,并按照要求匹配信息。
Many people think of guys as being carefree when it comes to their appearance. But in fact, a lot of guys spend plenty of time in front of the mirror. 1 .
Body image is a person’s opinions and feelings about his or her own body and physical appearance. 2 . You appreciate your body for its capabilities and accept its imperfections.
So, what can you do to develop a positive body image? Here are some ideas:
Recognize your strengths. Different body types are good for different things. What does your body do well? Maybe your speed, strength, or coordination makes you better than others at a certain sport. That may be basketball, table tennis, mountain biking, dancing, or even running. Or perhaps you have non-sports skills, like drawing, painting, singing, playing a musical instrument, writing, or acting. 3 .
Exercise regularly. Exercise can help you look good and feel good about yourself. Good physiques (体形) don’t just happen. 4 . A healthy habit can be as simple as exercising 20 minutes to one hour three days a week. Working out can also lift your spirits.
Respect your body! Practicing good habits --- regular showering; taking care of your teeth, hair, and skin; wearing clean clothes, and so on --- can help you build a positive body image.
5 . Your body is just one part of who you are. Your talent for comedy, a quick wit (智慧), and all the other things make you unique. So try not to let small imperfections take over.
A.Use this as an opportunity to discover what you’re good at. |
B.Be yourself. |
C.They care just as much as girls do about their body image. |
D.Just explore talents that you feel good about. |
E. They take hard work, regular workouts, and a healthy diet.
F. The good news is that self-image and body image can be changed.
G. Having a positive body image means feeling satisfied with the way you look.
