Intelligence and its Measurements

 

Intelligence has been looked at, discussed and studied for centuries. Intelligence, its measurements, types and much more are of great interest to me. This topic appealed to me because it is so different from what other TDP students researched. The book, Aha! The Most Interesting Book You'll Ever Read About Intelligence encouraged my interest in this topic, and I wanted to incorporate it into my project. Therefore, up popped intelligence. My original topic was intelligence measurements but I could do so much more. That was when my work on intelligence began.

I wanted to learn everything about intelligence. Sadly, my project got too big and I had to eliminate animal and artificial intelligence from my research. I could not cover all parts of the topic, so I decided to focus on those of greatest interest to me. I learned a lot more than I expected to learn but this didn't come from a stack of research paper. This came from my mind giving me a different view on disabilities and how one can be intelligent. This project really gave me a different view on the world.

During the course of my research, I used a lot of sources. I used many different sources of research including books, journal and encyclopedia articles, and websites. Some of the books I read were quite complicated, but others were easier to understand, such as my favorite source, Aha! There are entire websites devoted to intelligence. In addition to learning a lot about intelligence, I learned a lot about how to do research.

To talk about intelligence, there needs to be talk about the brain. An adult human brain weighs about three pounds but when we came into our world, our brain weighed about one pound. We gain two pounds of brain because of neuron connections. Our brain is divided into lobes, each one doing a different kind of work. Our brain is also divided into halves. The left part is supposed to do the logical, sequential, rational, analytical and objective thinking. It also looks at parts to get the whole idea. The right hemisphere does the random, intuitive, holistic, synthesizing and subjective work. It looks at the whole idea first, no details.

How do we think? The human brain has a lot of neurons. The approximate number is one hundred billion. An example is while one is reading a report, the eyes send what is seen on neuron connections. It goes to the language part of the brain. Then, the language part of the brain decodes what is seen. It would take about three thousand, one hundred seventy-one years to count, non-stop, at a rate of one per second, all of the neurons in the brain. Then, consider leap years and the time needed to state those huge numbers. Even though the brain is sensitive and fragile, there are no pain receptors. The brain needs 20% of the body's oxygen supply and the same amount of the energy supply. The brain is a very important part of intelligence.

Intelligence quotient tests have developed quite a bit over the years. Scores used to rely on a person's CA (chronological age) and MA (mental age). An IQ was calculated by dividing the CA by the MA. For example, if a ten-year-old had the knowledge of a thirteen-year-old, the equation would be: 1.3 multiplied by 100=130. In 1916, Binet and Simon, two French psychologists, looked at the accuracy of the tests and altered them somewhat. The reason they are called Stanford Binet and not Simon Binet is because they were brought to the U.S.A. by a psychologist at Stanford University. They are now called Revised Stanford Binet Tests.

IQ tests were originally used as a way to identify children struggling in school. They were used as a measure of general intelligence. There are many types of these tests. They can focus on verbal ability, spatial skills, analytical skills and more. IQ scores have been rising steadily during the last decades. This increase in scores is referred to as "The Flynn Effect" for James Flynn, the first person to report on this. Scientists think there are many reasons why scores have gone up. Some possible reasons are better standards of living, better schools, new IQ tests that do not have as much cultural bias, and nutrition. It may also be affected by more stimulating environments such as zoos. Children today also have had more experiences with testing and technological developments.

IQ tests are not fair for all people. If there are people who have been taught in a difference place or way, their answers would be different. This is called cultural bias. Bias means one is favoring one side too much. Another problem is people might think in different ways when answering reasoning questions. What would one choose to carry food with? A lunchbox or a large bowl-shaped stone? This can depend on what you are used to carrying food with.

The average person has an IQ of 100 points. The number 100 was chosen just for simplicity. The highest score someone can achieve on an IQ test is 200. Scientists argue about how many points one has to score to be considered a genius, but generally agree that 135-145 or higher is about right. Remember, however, IQ tests are not always accurate.

Boys may not like it, but there are a lot of factors against them when considering intelligence. Women's brains are smaller but have more area because they have folds. These folds allow more neurons and synaptic connections to pack into the brain. Little girls speak earlier than little boys. Since many early areas of study use language, girls often outscore boys. On average, girls outperform boys on the key tests at ages seven, eleven, fourteen, sixteen, and eighteen. The only things I could find that indicated that boys were smarter than girls was that, on average, girls have greater verbal skills while boys have greater mathematical and spatial skills. These differences may indicate the need for separate IQ tests for boys and girls.

When one is not the best in spelling, does that mean lack of intelligence? There are difference types of intelligence. According to Howard Gardener, these are the seven types:

*Verbal/Linguistic - the ability to use words and language
*Logical/Mathematical - the capacity for inductive and deductive thinking as well as the use of numbers and recognition of abstract patterns.
*Visual/Spatial - the ability to visualize objects and spatial dimensions and to create internal visions and pictures.
*Body/Kinesthetic - the wisdom of the body and controlling physical motion
*Musical/Rhythmic - the ability to recognize tonal patterns and sounds as well as sensitivity to rhythms
*Interpersonal - the capacity for person to person communications and relationships
*Intrapersonal - the spiritual inner states of self-reflection and awareness

If someone is great at dancing, that person has body/kinesthetic intelligence. A great pianist would have musical/rhythmic intelligence. Everybody is intelligent in their own way.

There is one more important kind of intelligence called emotional intelligence. This is the ability to understand and control emotions. Jennifer Brice, researcher, says that higher emotional intelligence in children makes them less likely to get into fights, less likely to take alcohol, drugs and the like, and are more social. Psychologist David B. Caruso has developed an IQ test which assesses emotional intelligence. Emotional intelligence is just as important as the other seven types.

Mental disabilities are a function or problem with one's brain. Although some mentally disabled people suffer from a lack of intelligence, many have skills in highly specific areas. There is a very interesting group of people with Savant Syndrome. These individuals may have low general intelligence, but they can have amazing talents. Math and music are some of the most popular. Savant Syndrome is one of the most interesting things you can read about on the topic of intelligence.

Kim Peek is the man who inspired "Rain Man," a famous movie. Kim was born on November 11, 1951. His head is 30% larger than he average human head. A brain scan revealed that one lobe literally exploded. Kim has read about 7,600 books and has probably memorized all of them, even phone books. Kim may not be able to dress himself , but he is one of the most interesting people that can be read about.

"I don't think anybody could spend five minutes with Kim and not come away with a slightly altered view of themselves, the world, and our potential as human beings," says Barry Morrow, the man who wrote the screenplay for "Rain Man." Kim Peek is one of the most intricate people alive today. His life demonstrates that a low IQ does not prevent a person from accomplishing amazing things.

Education is another important part of intelligence. Many kids say they "hate" school but a report done in 1997 stated that 81% of kids think it is "cool" to be smart. The report also noted that 67% of kids look forward to school compared with 63% in 1996. 71% of kids aged thirteen through seventeen plan to go to college compared with 55% in 1996. Absence from school can cause a drop in IQ scores. School is highly important to intelligence.

Food may also have an impact on intelligence. Scientists once did an experiment in which they removed artificial flavor, color, and dye from a school's menu. At the time, 120000 students were performing two or more grades below average. After the change, the number dropped to 50000. Coffee, fish, and blueberries are also supposed to be small brain boosters. Food may not be the most important part of intelligence but it does have an impact.

There is another interesting condition called Williams Syndrome. This is a very rare congenital condition. Although afflicted people struggle with writing, math and reading, they are extremely skilled with spoken language and are often very sociable. Williams Syndrome is caused by the loss of a tiny piece of chromosome. Williams Syndrome is another interesting mental state.

One of the people who first comes to mind when we think of genius is Albert Einstein. He won the Nobel Prize, convinced others that time is the fourth dimension, developed the equation E=MC2 and much more. He was born in Ulm, Germany, on March 14, 1879. Albert was very quiet in school until he learned about magnetism, which started him asking many questions. When he was in high school, his family moved, leaving him. Considered a slow student who asked to many questions, Albert was dismissed from school. He then went with his family to Switzerland and went to college. After graduation, he got a job with the Patent Office. He then married Mileva Maric and in 1905 published his famous theory of relativity. In 1909, he became a professor. In 1914, he accepted a teaching post in Berlin, Germany, leaving his wife behind. He divorced and was remarried to a woman named Elsa. Although he won the Nobel Prize, Adolph Hitler issued a death warrant for Einstein. He and Elsa fled Germany and settled in Princeton, New Jersey. Einstein lived there until his death in 1955. His brain was studied and was discovered to be 15% wider in one lobe. The brain also had a strange set of grooves. Einstein is one of the major figures of the twentieth century. His scientific genius continues to serve us.

There are many fun and interesting facts about intelligence. It does not always matter how high the IQ score is but how one's intelligence is used that is most important. Six-year-old children who take singing or piano lessons score an average of seven points higher on IQ tests. Gifted children usually have several of these qualities:

*Never stopped asking questions
*Talked and walked early
*Never needed much sleep
*Wide vocabulary
*Read early
*Takes the main part while playing
*Has a great imagination
*Strong physical and mental energy
*Always is reading
*Pays attention to details
*Loses interest when doing the same thing over and over
*Lively mind
*Grasps a new idea quickly
*Has a lot of concentration when interested

The saying that we use only 10% of our brain is NOT TRUE. We use 100% of our brains. A organization called MENSA is a society for smart people! There was also a theory called the Mozart effect. This was when people thought Mozart music could make you smarter. This is no longer believed.

There are a lot of occupations related to intelligence. One occupation related to my topic is that of neuroscientist. If one wants to enter that profession, he or she have to get several educational degrees including college and graduate school. People who teach this subject have doctoral degrees in neuroscience. People who diagnose medical conditions or perform brain surgery must go to medical school and specialize in neuroscience. Another job is that of psychologist. A psychologist must also attend college and graduate school, and he or she must get a doctorate in psychology. A psychologist can either teach academic courses or counsel patients with questions regarding mental and/or social health. There are many other jobs that have to do with intelligence since intelligence plays a key role in our lives.

Intelligence may have been looked at, discussed and examined for centuries, but I had much less time. I read what felt like everything possible about intelligence. If I had more time, my report would be much longer. I thought this report was very interesting and highly educational. Time whizzed by. I feel like I started it only three days ago, and now I'm at the end. The report was fun to do and I can not wait for the one I will do next year.
