Binet in cooperation with Theodore Simon, has modified the original test, changing it into a useful children and adolescents test. Is known as the Binet- Simon scale. Moreover, in 1916 the scale was revised by Luis Terman of Stanford University, called the Stanford- Binet intelligence scale. Terman developed the concept for comparing child’s mental age with their chronological age by calculating the intelligence quotient( IQ). Secondly, theory of intelligent launched in England by Charles Spearman( 1863- 1945), who said that there is a general intellectual factor “g” , which is present in all...
