An intelligence quotient (IQ) is a total score derived from a set of standardized tests or subtests designed to assess human intelligence. [1] Originally, IQ was a score obtained by dividing a person's mental age score, obtained by administering an intelligence test, by the person's chronological age, both expressed in terms of years and months.
David Wechsler, developer of the Wechsler–Bellevue Scale of 1939 (which was later developed into the Wechsler Adult Intelligence Scale) popularized the use of "deviation IQs" as standard scores of IQ tests rather than the "quotient IQs" ("mental age" divided by "chronological age") then used for the Stanford–Binet test. [67]
One hindrance to widespread understanding of the test is its use of a variety of different measures. In an effort to simplify the information gained from the Binet–Simon test into a more comprehensible and easier to understand form, German psychologist William Stern created the well known Intelligence Quotient (IQ).
Intelligence quotient (IQ) tests include the Stanford-Binet, Raven's Progressive Matrices, the Wechsler Adult Intelligence Scale and the Kaufman Assessment Battery for Children. There are also psychometric tests that are not intended to measure intelligence itself but some closely related construct such as scholastic aptitude.
The non-verbal performance scale was also a critical difference from the Binet scale. The earlier Binet scale had been persistently and consistently criticized for its emphasis on language and verbal skills. [6] Wechsler designed an entire scale that allowed the measurement of non-verbal intelligence. This became known as a performance scale.
The g factor [a] is a construct developed in psychometric investigations of cognitive abilities and human intelligence.It is a variable that summarizes positive correlations among different cognitive tasks, reflecting the assertion that an individual's performance on one type of cognitive task tends to be comparable to that person's performance on other kinds of cognitive tasks.
The test is used to determine not only the individuals intelligence quotient, but also the strengths and weaknesses of the individual. The test consists of questions ranging from "English, reading, math, and logic problems" [ 14 ] The Wonderlic test is notoriously used by NFL teams to help gain a better understanding of college prospects during ...
It generates a Full Scale IQ (formerly known as an intelligence quotient or IQ score) that represents a child's general intellectual ability. It also provides five primary index scores, namely Verbal Comprehension Index, Visual Spatial Index, Fluid Reasoning Index, Working Memory Index, and Processing Speed Index.
