What contribution did Lewis Terman make to intelligence testing?

Lewis Terman is best known for creating the Stanford-Binet test, an adaptation and revision of the original Binet-Simon intelligence test. His work significantly advanced the field of intelligence testing by providing a more reliable and standardized method of assessing cognitive abilities in individuals, particularly children. The Stanford-Binet test incorporated a range of cognitive tasks designed to measure various aspects of intelligence, such as reasoning, problem-solving, and memory, allowing for a comprehensive evaluation of an individual's intellectual capabilities.

This test became one of the most widely used intelligence assessments and formed the basis for many subsequent intelligence tests. Terman's contributions were foundational in formalizing the study of intelligence, particularly in how it is quantified and understood in educational settings, making his work integral to the evolution of psychological testing.
