The Genetic Studies of Genius, later known as the Terman Study of the Gifted, is the oldest and longest-running longitudinal study in the field of psychology. It was begun by Lewis Terman at Stanford University in 1921 to examine the development and characteristics of gifted children into adulthood.
The results from the study have been published in five books, a monograph, and dozens of articles. A related retrospective study of eminent men in history by Catharine Cox, though not part of the longitudinal study, was published as part of the Genetic Studies of Genius. It further inspired the ongoing Study of Mathematically Precocious Youth longitudinal study.
Terman had previously performed studies in intelligence, including his doctoral dissertation. In 1916, he adapted Alfred Binet's intelligence test for the United States and expanded its range. The result was the Stanford–Binet Intelligence Scales, which are still in use tod
