Measurement of intelligence : The History

Описание: In the quirky world of intelligence testing, Sir Francis Galton's wild idea to measure smarts via skull size fizzled out . But his legacy lived on through Raymond Cattell, who coined the term "mental test" and stressed on standardization.

Cut to 1905: Alfred Binet & Theodore Simon cracked the code with the Binet-Simon Intelligence Scale. Lewis Terman tweaked it in 1916, creating the Stanford Binet Test. Meanwhile, war broke out, and Robert Yerks whipped up Army Alpha & Beta tests to size up soldiers.

Fast forward to 1939: David Wechsler shook things up with the Wechsler-Bellevue Scale. By 1955, WAIS was born, getting a major revamp in 2008 with WAIS-IV. The evolution of IQ testing was a wild ride.
