IQ
IQ is the number of intelligence businesses. Intelligence is usually called intelligence. It is the ability of people to understand objective things and use knowledge to solve practical problems. Intelligence involves multiple aspects, such as observation, memory, imagination, analysis and inference, thinking, and adaptability. The intelligence level is usually expressed by the number of intelligence businesses, which is used to indicate the level of intelligence development.
In 1905, French psychologists developed the first bi Nai-Simon intelligence scale, which was introduced to China in 1922. In 1982, it was revised by Mr. Wu tianmin from Beijing, with 51 questions in total, it is mainly suitable for the intelligence of primary school students and junior high school students. In 1916, wppsz was developed by wppsz for adults (WAIS), wisc, and 4-6.5 children (wppsz ), wei's scale was introduced into China in the middle and late 1980s s and has been revised and published in Chinese, so it is widely used.
There are two types of IQ: Ratio IQ, and intelligence age = actual age of intelligence quotient. Assume that a person's mental age is equal to his actual age. His IQ is 100, indicating that he or she has medium intelligence. The other is the deviation IQ, which uses the ratio of a person's score to the average intelligence of normal people in the same age group as the IQ. Today, most mental testing attempts to use IQ deviation.
① In order to accurately express an intelligence level, the Intelligence literacy experts put forward the concept of a poor IQ, that is, using a person in his peer age, this is measured by calculating the number of standard deviations from the average value of the subject, which is known as the IQ ).
② For example, for two adults of different ages, a person's mental score is higher than the average score of the same age group, and a score is lower than the average value of the same age group, then we come to the conclusion: the IQ of the former is higher than that of the latter.
③ At present, most of the intelligence literacy values use IQ to indicate a person's intelligence level.
④ Intelligence quotient distribution of the population.
In a typical smart Intelligence Test in modern times, if the average IQ of the population is set to 100, the IQ of half of the population is between and based on a certain statistical principle, among them, 90-25% and-people each account. IQ accounts for 14.5% of 7%, IQ accounts for 3% of 0.5%, and 130-140 accounts for 140, and the remaining 25% accounts for more than 100, and IQ of accounts for less.
⑤ Extraordinary intelligence and low intelligence
After the advent of intelligence testing, it is easier to differentiate the differences in intelligence. People found that people with extremely high IQ (more than 130 IQ points) and people with extremely low IQ (less than 70 IQ points) are minority, moderate or close to moderate intelligence (IQ points) people account for about 80% of all people. People with more intelligence than normal are referred to as super intelligence. Those with lower intelligence than normal are referred to as low intelligence.
We use the mental Intelligence Scale compiled by American psychologist Wexler, which was revised by Yao xianxian, Hunan Medical University, China and formulated the Chinese norm. We are now able to look up children aged 6-16 and adults over 16 years old. Through psychological attention, you can understand your intelligence level and potential, identify the damage caused by traffic accidents, and provide scientific evidence to give full play to your own advantages, scientifically fill in the college entrance examination volunteers, and offer superior health and education.
The IQ test contains eleven projects, including common sense, understanding, arithmetic, similarity, memory, words, images, blocks, arrangement, puzzles, and symbol verification, it takes about one hour to complete the verification. It takes about one hour to summarize and analyze and write the verification report.
