Iq
IQ is intelligence quotient. Intelligence is usually called wisdom, also called intelligence. Is the ability of people to understand objective things and use knowledge to solve practical problems. Intelligence contains many aspects, such as observation, memory, imagination, analytical inference ability, thinking ability, adaptability and so on. The intelligence quotient is often used to indicate the level of intellectual development.
In 1905, French psychologists developed the first measured intelligence scale-the Binet-Simon Intelligence Scale, which was introduced to China in 1922 and revised by Mr. Wu Tianmin of Beijing in 1982, with a total of 51 items, mainly suitable for measuring the intelligence of pupils and junior high school students. 1916 the United States Wechsler compiled Wechsler Adult Intelligence Scale (WAIS), Children's intelligence Scale (WISC), applicable 4-6.5 children's Merriam-Webster's Intelligence Scale (WPPSZ), the Merriam-Webster scale was introduced in late 80 and later in China after the revised publication of the Chinese version, thus the application of a wider.
There are two kinds of IQ, one is the ratio IQ, the intellectual Age ÷ chronological age = Intelligence quotient. Assuming that someone is lodged equal to his age, his IQ is 100, indicating his intelligence is moderate. There is also a difference in IQ, the ratio of a person's test score to the average age group of normal intelligence as an IQ. Most intelligence tests today use a deviation IQ.
① in order to accurately express an intelligence level, intelligence measurement experts put forward the concept of a deviation IQ, that is, a person in his own age in a position, that is, by calculating how many deviation from the average number of standard deviation, this is the deviation IQ, also known as IQ (IQ).
② For example, two adults of different ages, a person's intelligence measured score is higher than the average age group scores, and a test score is lower than the average age group, then we make this conclusion: The former IQ is higher than the latter.
③ for now, most of the intelligence is measured by a deviation IQ (IQ) to indicate a person's intellectual level.
Intelligence quotient distribution of the ④ crowd.
In the modern typical intelligence test, set the average IQ of the main population is 100, then according to a certain statistical principle, half of the population IQ, between 90-110, among them IQ in 90-100 and 100-110 of the people accounted for 25%. IQ accounted for 14 of the 110-120. 5%, the IQ in 120-130 of the people accounted for 7%, 130-140 of the people accounted for 3%, the remaining 0. 5% people have an IQ of 140 or more, and another 25% IQ is below 100 points.
⑤ Intellectual paranormal and intellectual inferiority
After the advent of intelligence testing, the difference in intelligence becomes easy. People find that IQ is extremely high (IQ is above 130) and people with very low IQ (IQ under 70 points) are few, intelligence medium or close to Medium (IQ in 80-120 points) between about 80% of all population, intelligence more than normal, we call it intelligence extraordinary, those intelligence is lower than the normal person, We call it low intelligence.
We use the intelligence scale compiled by American psychologist Wechsler, which was revised by China's Hunan medical giant Gong Yaoxian, and formulated the Chinese norm. We are now able to measure children aged 6-16 and adults over 16 years of age. Through psychological measurement can understand their intelligence level, potential, identification of traffic accidents lead to intellectual damage, in order to play their own advantages, scientific completion of the college Entrance Examination volunteer, prenatal and other scientific basis to provide.
IQ test consists of 11 items, common sense, understanding, arithmetic, similarity, memory, words, images, building blocks, permutations, puzzles, symbols to test, complete the entire test is about an hour, summary analysis, write test report about one hours.
