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]
The Wechsler Adult Intelligence Scale (WAIS) is an Intelligence Quotient (IQ) test designed to measure intelligence and cognitive ability in adults and older adolescents. [1] For children between the ages of 6 and 16, Wechsler Intelligence Scale for Children (WISC) is commonly used.
Instead, Stern proposed dividing an individual's mental age by their chronological age to obtain a single ratio. This formula was later improved by Lewis Terman, who multiplied the intelligence quotient by 100 to obtain a whole number. [7] Stern, however, cautioned against the use of this formula as the sole way to categorize intelligence.
During much of the 19th century, theories of intelligence focused on measuring the size of human skulls. [3] Anthropologists well known for their attempts to correlate cranial size and capacity with intellectual potential were Samuel Morton and Paul Broca. [3] The modern theories of intelligence began to emerge along with experimental psychology.
Terman and Merrill attempted to calculate IQs with a uniform standard deviation while still maintaining the use of the mental age scale by including a formula in the manual to convert the ratio IQs with means varying between age ranges and nonuniform standard deviations to IQs with a mean of 100 and a uniform standard deviation of 16.
The number this calculation produced was the widely known intelligence quotient or IQ. For many people, both testers and tested, this number became a person's precise built-in intelligence. [ 3 ] Théodore Simon criticized this revision of the Binet-Simon test, arguing it to be a betrayal of the test's objective.
Human intelligence is the intellectual capability of humans, which is marked by complex cognitive feats and high levels of motivation and self-awareness.Using their intelligence, humans are able to learn, form concepts, understand, and apply logic and reason.
