Which area did Lewis Terman contribute to in psychology?

Lewis Terman was a significant figure in the field of psychology, particularly known for his contributions to intelligence testing. He is best recognized for his work in adapting and standardizing the Stanford-Binet Intelligence Scales, which became one of the most widely used intelligence tests in the world. Terman's research expanded the understanding of intelligence, including its measurement and implications for educational and psychological assessments.

His focus on intelligence testing also involved the study of giftedness, as he was among the first psychologists to explore the characteristics and needs of individuals with high IQs. By defining and classifying different levels of intelligence, Terman's work laid the groundwork for future research in the area of intelligence and its impact on learning and development.

This emphasis on empirical measurement and the desire to understand cognitive abilities distinguishes Terman's contributions from other psychological areas such as behaviorism, developmental psychology, or cognitive therapy, which focus on different aspects of human behavior and mental processes. Thus, Terman's primary legacy is firmly rooted in the field of intelligence testing.
