How do we measure it: extremes of intelligence. Intelligence tests: history and present: intellectual disability, genius/giftedness, other ways of defining intelligence, fluid vs. crystallized intelligence, emotional and social intelligence, biological and environmental influences. Intelligence: the ability to understand complex ideas, adapt effectively to the environment, learn from experience, engage in reasoning and overcome obstacles (textbook) Iq = 5/4 x 100 = 125: revised binet"s test, brought intelligence testing to the u. s, developed the stanford-binet intelligence tests. Intelligence quotient (iq): a measure of individual intelligence relative to a statistical normal curve. Intellectual disability: a condition diagnosed in individuals with iq scores below. You should know this: only about 2% of people have an iq score less than 70 (more than 2 sd below mean) Identified at birth or early in infancy: many require significant assistance and supervision, language skills frequently affected, 10 - 40% experience emotional or behavioral problems.
