The Answer is The French government asked Alfred Binet to develop a test that would assist with identifying school children who may need extra help.Binet thought that intelligence allows a person to think,understand,reason,and adapt to overcome obstacles.He also thought that it was the result of a complex interaction of processes including memory,attention,and comprehension.Binet and his colleague,Theodore Simon,developed thirty tasks of increasing difficulty that,when completed,would demonstrate the child's current abilities.The researchers gave the tests to children of different ages thus creating a "standard score" for each age.When the test was administered to a child,the score was compared to Binet's standards to determine the child's "mental age." The mental age was divided by the child's actual age to create an "intelligence quotient" (IQ).The notion of dividing a test score by a standard score was carried over to the United States in the form of the Stanford-Binet intelligence test.However,administrators of this test claimed it measured innate intelligence instead of current abilities (which was the premise of Binet's tests).
