How Lewis Terman Influenced the Field of Psychology

Close

Lewis Terman was an influentialpsychologistwho is known for his version of the Stanford-Binet intelligence test and for his longitudinal study of giftedness. Hisresearchis the longest-lasting longitudinal study ever conducted. His work contributed to the understanding of how intelligence influences life success, health, and outcomes.

Lewis Terman’s Influence on Psychology

Terman is best known for:

Early Life

Lewis Madison Terman was the 12th of 14 children born on January 15, 1877 to a farming family in Indiana. While few of his peers studied past the 8th-grade, Terman was both bookish and ambitious. His early experiences were perhaps what fueled his later passion for studying intelligence and giftedness.

Career and Research

Terman’s Ph.D. thesis centered on mental tests that could be used to distinguish gifted students from those that were cognitively impaired. He developed tests that measured complex cognitive abilities that included measures of creativity, mathematical ability,memory, motor skills, logic, and language mastery.

After graduating, he initially worked as a school principal in California and two years later became a professor at Los Angeles State Normal School. In 1910, he became a professor at Stanford University, where he would remain until his death in 1956.

The first wide-scale use of Terman’s test occurred during the First World War, where the test was adapted and combined with other assessments to form the Army alpha (text-based) and Alpha-beta (picture-based) tests. Millions of soldiers were given these assessments, and those who received an “A” or “B” score were promoted to officer training while those who received a “D” or “E” were not.

Terman was also a noted eugenicist, once citing Francis Galton as a prime influence. At one point, he administered English tests to native Spanish-speakers as well as unschooled Black students and concluded that the ensuing low scores were the result of inheritance and had a racial basis. Terman was also a member of the Human Betterment Foundation, a group that advocated, among other things, forced sterilization of those who were deemed mentally unfit.

Terman’s Genius Study

In 1921, Terman began his “Genetic Studies of Genius,” alongitudinal studythat set out to investigate whetherhigh IQ students were more successful in life. What he found was that his high IQ subjects (which he referred to as “Termites”) tended to be healthier, taller, and more socially adapted than other kids.

Based on his results, Terman suggested that gifted children should be identified early, offered tailored instruction, and have access to specially-trained teachers. Terman found that while many of his high IQ subjects were very successful, not all fared well and most actually turned out no better than the average. He found that those who ended up being the most successful tended to rate higher on self-confidence, perseverance, and goal-orientation as children.

Terman published a number of books and articles that detailed the research he conducted looking at intelligence and IQ testing. Some of these include:

Contributions to Psychology

Lewis Terman played an important role in the early development of educational psychology, with his intelligence test becoming one of the most widely used psychological assessments in the world. He advocated for support and guidance for kids identified as gifted in order to nurture their talents and abilities.

Wrestling with Terman’s difficult legacy involves weighing his many contributions to the field and the influence his IQ test had on the world against the racist attitudes that motivated so much of his work.

“One one hand, his work inspired almost all the innovations we use today to challenge bright kids and enrich their education,” wrote Mitchell Leslie forStanford Magazine. “On the other hand, as biographer Minton points out, the very qualities that made Terman a groundbreaking scientist - his zeal, his confidence - also made him dogmatic, unwilling to accept criticism or to scrutinize his hereditarian views.”

In one study ranking the most influential psychologists of the 20th century, Terman was tied withG. Stanley Hallat number 72.

Terman died on December 21, 1956.
