IQ

1. = Intelligence Quotient

IQ is the abbreviation of intelligence quotient, which means intelligence quotient for short. It is an index to measure the level of individual intelligence development. It was first put forward by German psychologist L．W．Stern, and American psychologist Tuimeng quoted IQ in the Stanford-Binet Scale and improved it. IQ is the quotient obtained by dividing the intellectual age (mental age) by the actual age and multiplying it by 1, that is, the ratio IQ. Its calculation formula is:

calculation method: IQ = Ma (intellectual age) /CA (actual age) ×1

It is based on the assumption that intellectual age increases with actual age. In fact, intelligence does not increase linearly with age, and it basically stops developing after the age of 16. Obviously, the ratio IQ has great limitations. When wexler, a famous American medical psychologist, compiled the children's intelligence scale, the test results adopted the calculation method of stray IQ. It is calculated according to the mean () and standard deviation SD in statistics, that is, the individual score with standard deviation deviates from the average score of his age group, so it is not affected by the age of the examinee. This calculation method not only overcomes that psychological age can only be compared horizontally between the same age groups, but also overcomes that ratio IQ can only be compared between different age groups. Nowadays, the IQ calculation method of deviation IQ is often used.

Psychologists use intelligence test as a tool to measure people's intelligence level, and use IQ to show the quality of intelligence. In ancient times, there were also many intelligence tests. For example, in the Northern Qi Dynasty in China, Liu Zhou used the test of "making the left hand draw a square and the right hand draw a circle, making it all work at one time" to measure people's intelligence. None of these tests had certain indicators. Nowadays, the widely used IQ scoring method originates from Binet.Alfred's concept of intellectual age.

intellectual age, also known as mental age, refers to a certain age level of intelligence, which is a measure of a person's intelligence. The original Simon-Binet.Alfred intelligence test used the age scale to express the test scores. Here's the age scale, that is, in the scale, each age group has six questions, and each question represents two months' intellectual age. Add up the intellectual ages of the sub-scales of each age group correctly, and it is the intellectual age of the child.

Later, it was found that the age of intelligence is 1 years old, which has different meanings for children aged 8, 1 and 15. Therefore, in 1916, the concept of IQ was adopted in the revised Si-Bi Scale. IQ is the quotient of intellectual age and actual age mentioned above. When you divide two ages, you get more decimals. In order to conform to people's habits, psychologists round up this quotient, that is, multiply it by 1:

IQ = Ma (age of wisdom) /CA (age of maturity) ×1

If intellectual age represents the level of psychological development and is an absolute quantity, then IQ represents the rate of psychological development and is a relative quantity. Obviously, IQ is more scientific than intellectual age.

We can see from the above formula that IQ is greater than 1. But is 117 a "genius" score?

Some people have made statistics on the proportion of each IQ score segment in the population:

Only 1% of people in the population have an IQ above 14; 11% IQ is between 12 and 139; 18% belongs to 11 ~ 119 points; 46% belong to 9 ~ 19 points; 15% belongs to 8 ~ 89 points; 6% belongs to 7 ~ 79 points; In addition, 3% of people have an IQ of less than 7 points, which means they are mentally retarded.

What is EQ?

it is the abbreviation of emotion quota. Chinese means "emotional intelligence" or "emotional intelligence", which is abbreviated as emotional intelligence.

it represents a person's ability of EmotionalIntelligence. Simply put, EQ is an index of one's ability to manage one's own emotions and others' emotions.

the birth of p>EQ

As early as 192, E.L.Thorndike, a professor at Columbia University in the United States, first put forward the concept of SocialIntelligence, arguing that people with high social intelligence "have the ability to understand and manage others and can take wise actions in interpersonal relationships.

in 1926, the first social intelligence test was launched. The topics of the questionnaire included identifying the emotional state of the characters in the pictures and judging the problems in interpersonal relationships.

However, in the next few decades, the efforts of psychologists in this field stopped, mainly because everyone was busy developing and studying IQ tests. At that time, it was thought that IQ (that is, a person's ability in mathematics, logic, Chinese and space) would determine everyone's ability to learn and be taught, thus affecting future work development and performance.

Until 1983, American psychologist Professor Gana put forward the theory of "Multiple Intelligences", which had a great influence on the current education system. He believes that the traditional definition of "intelligence" (that is, IQ), which only focuses on mathematical language ability, needs to be greatly revised, because a person's IQ has a high positive correlation with school academic performance (the higher IQ, the better homework), and has little to do with other aspects, such as work performance, feelings and life satisfaction.

Professor Gana added several intelligences to his theory of multiple intelligences, including music, physical education and the ability to know oneself and others. These latter two items make the concept of "social intelligence" once again attached importance to by the educational and psychological circles.

The first person to use the term "EQ" was the psychologist ReuvenBar-on. In 1988, he compiled a special questionnaire (EQ-i) to test EQ. According to his definition, EQ includes those emotions and social skills that can affect our adaptation to the environment. There are five items: (1) self-eq, (2) interpersonal eq, (3) adaptability, (4) stress management ability and (5) general emotional state (optimism and happiness).

Then there are psychologists Salovey& Meyer (Salovey &; ; Mayor) put forward the definition of emotional intelligence in 199. They believe that emotional intelligence should be distinguished from optimism and other personality traits, so their definition of EQ emphasizes the understanding and application of emotions.

At present, another EQ test (MSCEIT) widely used in various countries is their latest research achievement. Among them, there are several major problems: (1) the ability to perceive and express emotions; (2) the ability to imagine emotional states in the brain; (3) the ability to understand emotions; and (4) the ability to control emotions.

the development of EQ

The psychologist who really made the word "eq" go out of the academic circle of psychology and become a catchy everyday language for everyone is Professor DanielGoleman of Harvard University. His book EQ (EmotionalIntelligence), published in 1995, reached the best-seller list of all countries in the world and set off an EQ craze all over the world.

Goldman found that a person's EQ has a very important influence on his performance in the workplace. For example, a survey of employees in the top 5 enterprises in the United States found that, regardless of industry, the contribution ratio of IQ and EQ to a person's success at work is IQ: EQ = 1: 2, that is to say, the influence of EQ on job achievement is twice that of IQ, and the higher the position, the greater the influence of EQ on job performance. In addition, for some job categories, such as marketing, business and customer service, the influence of EQ is more obvious.

Therefore, according to the performance in the workplace, Goldman put forward his work EQ architecture. After continuous testing and revision, at present, there are 4 major items and 18 minor items in Goldman's work EQ.

There are 18 items in so many contents, which are really eighteen martial arts, and everything is not simple. And to have all kinds of martial arts, wouldn't it be difficult to ascend to heaven?

Please don't worry. In fact, as long as a person has five or six EQ abilities among the eighteen EQ abilities, and they are evenly distributed among the four abilities, his performance in the workplace will be very bright.

To measure job EQ, the currently widely used scale is Emotional Competency Inventory (ECI), which has 11 questions in total. In particular, ECI uses a 36-degree all-round data collection method, which not only asks the client, but also understands the client's job EQ from his boss, subordinates and colleagues, and the results obtained are of course more objective and accurate.

So, as long as you master the work EQ, you can achieve your work achievement.

eq's development in growth

EQ is formed in infancy, shaped in children and adolescents, and it is mainly cultivated in acquired interpersonal interaction. Adolescence is a golden age for a person, because it is a transitional period for a person to become an adult. In this period, its learning and development tasks are very important. However, middle school students are faced with dramatic changes in physiology and psychology, as well as great academic pressure, which will cause psychological imbalance and complex psychological contradictions among modern middle school students, and even produce various adverse consequences. According to a survey report in 22 cities, in fact, 15%-2% of middle school students in China have various psychological problems, which are manifested in parent-child conflicts, tense partnership, weariness and learning difficulties, and exam anxiety. Most of these problems are related to students' self-control ability, and most of them stem from all kinds of irrational emotions that often gush out of their hearts. The quickest and most effective way to improve eq level is psychological training.

It is the goal of quality education to develop personality and ability, but all this comes from the improvement of psychological quality. To this end, we set up a training class for teenagers' psychological quality. Through psychological education and psychological training, we focus on developing students' non-intellectual factors, improving their self-psychological awareness and cognitive level, learning to control their own emotions, improving their inappropriate emotional behavior, improving their emotional intelligence level, and letting children learn to "be the masters of their own emotions", so that students can establish good values and a rational outlook on life, enhance their psychological adaptability, improve their learning ability, and respond to various pressures and challenges with a positive attitude.

It is every parent's wish to look forward to their children's success and success. As a parent who cares about their children's growth, do you only focus on their academic achievements and special abilities? For their healthy growth, please first pay attention to the cultivation of their psychological quality and improve their eq. Let the children find the lost laughter, study and live healthily and happily, and actively obtain excellent academic achievements and skills.

what is the most indispensable effect for making music? I believe most friends will answer: EQ! Yes, it is with this so-called "balanced" effector that our music will not be overloaded and the timbre of the instrument will be so rich. However, knowing that 1 plus 1 equals 2 is even more important to know why 1 plus 1 equals 2. Today, I stripped the effector naked and analyzed its working principle fundamentally.

"the principle of eq? Sound waves are made up of different harmonics! The so-called equalization process is to change the amplitude of these harmonics. " This statement is also right and wrong. Say it's right because the original intention of the equalizer is this. It's wrong because with today's mathematical algorithms, it is still impossible to deduce certain questions from answers. For example, the answer to a question is 1, and my question can be 2+8, 1+3+6, or even 5.5+4.4+.1, etc ... Waveforms are the same, and the same composite waveform can have countless harmonic combinations. Therefore, the effector can't distinguish the number and amplitude types of these harmonics at all. However, the inventor of equalization was very clever. He did not let EQ deal with unpredictable harmonics to change the timbre, but indirectly changed the timbre through a clever method.

From the chapter "Vibration and Wave" in the physics book of senior high school, we know that the frequency is equal to the reciprocal of the period. The so-called cycle refers to the time it takes for an object to complete a certain movement and return to its initial state.
