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.”

Maybe you are an average student. You probably think you will never be a top student. This is not necessary so, however. Anyone can become a better student if he or she wants to. Here is how.　　

1). Plan your time carefully. When you plan your week, you should make a list of things that you can have to do. After making the list, you should make a schedule of your time. First time for eating, sleeping, dressing, etc. Then decide a good, regular time for studying. Don’t forget to set aside enough time fro entertainment. A weekly schedule may not solve all your problems, but it will force you to realize what is happening to your time.　　

2). Find a good place to study. Look around the house for a good study area. Keep this space, which may be a desk or simply a corner of your room. Free from everything but study materials. No games, radios, or television. When you sit down to study, concentrate on the subject. 　　

3). Make good use of your time in class. Take advantage of class time to listen to everything the teachers say. Really listening in class means less work later. Taking notes will help you remember what your teachers say.　　

4). Study regularly. When you get home from school, go over your notes. Review the important points that your teachers mentioned in class. If you want to know what your teacher is going to discuss the next day, read the material in advance. This will help you understand the next class. If you do these things regularly, the material will become more meaningful, and you will remember it longer.　　

5). Develop a good attitude about tests. The purpose of a test is to show what you have learned about a subject. They help you remember your new knowledge. The world won’t end if you don’t pass a test, so don’t be overly worried.　

There are other methods that might help you with your studying. You will probably discover many others after you have tried these.
