This term was later used in by Alfred Binet and Theodore Simon, who published the first modern intelligence test, the Binet-Simon intelligence scale. Because it was easy to administer, the Binet-Simon scale was adopted for use in many other countries. These practices eventually made their way to the United States, where psychologist Lewis Terman of Stanford University adapted them for American use.
So if a five year-old child achieved at the same level as an average eight year-old, he or she would have a mental age of eight. Thus, a five year-old child who achieved at the same level as his five year-old peers would score a The score of became the average score, and is still used today.
The Wechsler scales contained separate subscores for verbal IQ and performance IQ, and were thus less dependent on overall verbal ability than early versions of the Stanford-Binet scale. The Wechsler scales were the first intelligence scales to base scores on a standardized bell curve a type of graph in which there are an equal number of scores on either side of the average, where most scores are around the average and very few scores are far away from the average.
Modern IQ tests now measure a very specific mathematical score based on a bell curve, with a majority of people scoring the average and correspondingly smaller amounts of people at points higher or lower than the average.
However, the relationship between IQ score and mental ability is not linear: a person with a score of 50 does not have half the mental ability of a person with a score of Charles Spearman was the pioneer of the theory that underlying disparate cognitive tasks is a single general intelligence factor or which he called g. As a result, the two terms are often used interchangeably. In order to develop an IQ test that separated environmental from genetic factors, Raymond B.
Cattell created the Culture-Fair Intelligence Test. Cattell argued that general intelligence g exists and that it consists of two parts: fluid intelligence the capacity to think logically and solve problems in novel situations and crystallized intelligence the ability to use skills, knowledge, and experience. He further argued that g should be free of cultural bias such as differences in language and education type.
This idea, however, is still controversial. Raven in This test is a nonverbal group test typically used in educational settings, designed to measure the reasoning ability associated with g. During the early years of research, the average score on IQ tests rose throughout the world. IQ tests are used to measure human intelligence quotient as measured against an age-based average intelligence score. IQ tests attempt to measure and provide an intelligence quotient, which is a score derived from a standardized test designed to access human intelligence.
There are now several variations of these tests that have built upon and expanded the original test, which was designed to identify children in need of remedial education. Currently, IQ tests are used to study distributions in scores among specific populations. Over time, these scores have come to be associated with differences in other variables such as behavior, performance, and well-being; these vary based on cultural norms. After decades of revision, modern IQ tests produce a mathematical score based on standard deviation, or difference from the average score.
Scores on IQ tests tend to form a bell curve with a normal distribution. IQ Bell Curve : In a normally distributed bell curve, half the scores are above the mean and half are below. The farther from the mean, the less frequent a given score is. Normal distributions are special, because their data follows a specific, reliable pattern.
Standard deviation is a term for measuring how far a given score is from the mean; in any normal distribution, you can tell what percentage of a population will fall within a certain score range by looking at standard deviations.
The scores of an IQ test are normally distributed so that one standard deviation is equal to 15 points; that is to say, when you go one standard deviation above the mean of , you get a score of
