Document Summary
History of intelligence: francis galton: english scientist, cousin of charles darwin, one of the rst people to look at intelligence scienti cally. In uenced by ideas of evolution, wrote a book called hereditary genius: belief: people do differ in intellect and intelligence is inherited. Alfred binet: french scientist, was given job of determining whether or not children needed. Came up with concept of mental age, children could be given a relative score: mental age = chronological age, advanced: mental age > chronological age, special ed: mental age < chronological age. Lewis terman: psychologist at stanford, created the stanford-binet test, added items and created standardized tests. 2. intelligence quotient (iq) a) (mental age/chronological age) * 100 (1) ex: if mental age is 6 but real age is 4, then have iq of 150. Therefore, smarter people (higher iq) get to have children, but not less intelligent people: some pioneers of iq testing were also believes in eugenics.
