intelligence test

Francis Galton - created the first intelligence test

eugenics movement—a movement bent on improving the human gene pool.

Alfred Binet - created the first Iq test

mental age - essentially, the average performance of people at a certain age.

Louis Leon Thurstone - With his new psychometric approach, he used factor analysis to reduce intelligence to seven primary factors: word fluency, verbal comprehension, spatial ability (positioning and direction), perceptual speed (the speed at which one can perceive and understand information), numerical ability, inductive reasoning (ability to identify patterns and make inferences), and memory.

Lewis Terman - looked for genetic explanation of Spearman’s general factor of intelligence.

Stanford-Binet intelligence quotient (IQ) test - This was a test that analyzed one’s mental age, divided it by their chronological age, and then multiplied by 100.

the Flynn Effect- which asserts that once states are stable, provide education, and are also affluent enough to afford ample nutrition to children, teens, and adults for proper brain development, one’s genetic potential for intelligence may be realized.

David Wechsler - developed the Wechsler Adult Intelligence Scale

aptitude tests--tests that predict a person’s future performance and capacity to learn.

percentile —a relative ranking out of 100 according to the values of a particular variable.

tests must accomplish three distinct goals— they must be standardized, reliable, and valid.

predictive validity – the diminishing ability of tests to measure future learning.

intellectual disability—formerly known as mental retardation—may affect intelligence scores and present those affected with difficulty in adapting to normal demands of independent living.

cognitively gifted - those born with high IQs and/or general intelligence
