How Geniuses Work
Without a doubt, Einstein was a genius. So was Isaac Newton, who invented
Physics. He also played a big role in the development of Calculus (微积分学), which
some people have trouble comprehending even after extensive classroom study.
Another genius, Wolfgang Amadeus Mozart, started composing music when he was 5
years old. Mozart wrote hundreds of pieces before his death in 1760 at age
35. The understanding of genius According to
conventional wisdom, geniuses are different from everyone else. They can think
faster and better than other people. In addition, many people think that all
that extra brainpower leads to strange behavior. And although geniuses are
fairly easy to spot, defining exactly what makes one person a genius is a little
trickier. Figuring out how that person became a genius is harder
still. There are two big things that make it difficult to study
genius. First, the genius label is subjective. Some people insist that anyone
with an intelligence quotient (IQ) higher than a certain value be a genius.
Others feel that IQ tests measure only a limited part of a person’s total
intelligence. Some believe high test scores have little to do with real genius.
Second, genius is a big picture concept. Most scientific and medical inquiries,
on the other hand, examine details. A concept as subjective as genius isn’t easy
to quantify, analyze or study. So, when exploring how geniuses
work, it’s a good idea to start by defining precisely what a genius is. A genius
isn’t simply someone with an exceptionally high IQ. Instead, a genius is an
extraordinarily intelligent person who breaks new ground with discoveries,
inventions or works of art. Usually, a genius’ work changes the way people view
the world or the field in which the work took place. In other words, a genius
must be both intelligent and able to use that intelligence in a productive or
impressive way. Genius and the brain The cerebral
cortex (大脑皮层), the outermost part of your brain, is where thought and reasoning
happen. These are your brain’s higher functions, which relate to basic survival,
take place deeper in the brain. Your cerebral cortex is the largest part of your
brain, and it’s full of wrinkles and folds. If you removed and stretched out an
adult human’s cerebral cortex, it would be about as large as a few pages of a
newspaper. It’s divided into several lobes (圆形的突起), and different regions within
these lobes handle specific tasks related to how you think.
Researchers have so far only figured out a few things about how the brain
affects intelligence. A 2004 study at the University of California found that
the volume of gray matter in parts of the cerebral cortex had a greater impact
on intelligence than the brain’s total volume. The findings suggest that the
physical attributes of many parts of the brain determine how smart a person
is. A 2006 paper in the journal Nature theorized that the way
the brain develops is more important than the size of the brain itself. A
person’s cerebral cortex gets thicker during childhood and thinner during youth,
According to the study, the brains of children with higher IQs thickened faster
than those of other children. Studies also suggest that, to some extent,
children inherit intelligence from their parents. Some researchers theorize that
this is because the physical structure of the brain can be an inherited trait.
In addition, the process of becoming really good at something both requires and
encourages your brain to wire itself to handle that particular task
better. Genius and intelligence Like genius,
intelligence can be difficult to quantify. Psychologists study intelligence
extensively. An entire field of study, known as psychometrics (心理测验学), is
devoted to studying and measuring intelligence. But even within that field,
experts don’t always agree on exactly what it is or how best to analyze it. And
while intelligence is central to genius, not all geniuses score well on
intelligence tests or perform well in school. Intelligence
testing has existed for thousands of years. The best known IQ tests started near
the end of the 19th century. Today, IQ tests generally measure a person’s
memory, language and mathematical abilities. IQ tests are also standardized so
that most people score between 90 and 110. A common perception is that anyone
scoring above a certain number—often 140—is automatically a genius. But in spite
of the existence of high IQ organizations, many scientists caution that there is
no such thing as a genius level IQ. Many educators and
researchers feel that, in general, standardized IQ tests do a good job of
predicting how well a child will perform in school. Schools often use these
tests to determine which children to place in gifted or special education
classes. Most colleges and universities and some employers also use standardized
tests as part of their application processes. However, in spite
of their prevalence, these tests are not safe enough. In general, some
minorities and people with lower income levels tend to score lower than people
from other racial and economic groups. Critics contend that this makes IQ tests
invalid. In addition, some researchers argue that the concept of IQ is too
limiting and doesn’t really give a full view of a person’s intelligence. They
feel that intelligence is a combination of many factors. Genius and
creativity There’s a big difference between being really
smart and being a genius. While geniuses tend to be exceptionally intelligent,
they also use imagination and creativity to invent, discover or create something
new within their field of interest. They break new ground rather than simply
remembering existing information. Geniuses do not usually
operate in isolation, either. Nearly all of them analyze the work of other great
minds and use that information to make new discoveries. Self taught geniuses, on
the other hand, often explore information in unexpected ways, due in part to
their lack of formal training. In either case, the ability to imagine new
possibilities is as important as general intelligence. Like
intelligence, creativity and imagination can be difficult to isolate, quantify
or explain. Some researchers believe that creative people have less potential
inhibition than other people. Potential inhibition is the unconscious ability to
ignore unimportant stimuli. Researchers think that creative people either
receive more stimuli from the world around them or ignore less of it. This may
also explain why creative people seem to be more prone to mental
illness. The creativity of geniuses also relates to productivity
and hard work. Sometimes, the most dramatic examples of genius involve people
who produce their best work at a very young age. However, not every genius
produces exceptional work early in life the way Einstein and Mozart did. Some,
like Ludwig yon Beethoven, do their best work later in life. We
may never know precisely where creativity comes from, why some people use their
creativity more than others or why some people are most creative during specific
times in their lives. We may not learn how one person ends up with the right
balance of brainpower, intelligence and creativity to become a genius. But it’s
clear that geniuses are central to advancements in science, technology and
understanding. Without geniuses, our understanding of mathematics, literature
and music would be completely different. Concepts that we now take for granted,
like gravity, planetary orbits and black holes, might still he
undiscovered. The study at the University of California in 2004 made a discovery that ______ .
