Document Summary
Henry goddard: administered intelligence tests to arriving immigrants and concluded certain races were feebleminded , resulting in the sterilization of mental defectives . Alfred binet and theodrore simon: developed the first intelligence test to identify children who needed remedial education by measuring their aptitude for learning independent of the child"s prior educational achievement. William stern suggested that this mental level produced by the intelligence test could be understood as a child"s mental age. Lewis terman formalized this with the development of the intelligence quotient/ratio iq, which is iq= (mental age/chronological age)x100. Due to anomalies with the intelligence quotient, psychologists devised the deviation iq= (person"s test core/average test core of people in the same age group)x100. This was then plotted on a normal curve. Two commonly used tests are the stanford-binet (updated many times from the original, most notably by lewis terman) and the wais (the wechsler adult intelligence scale).
