Who developed the first intelligence test?

Question

Accepted Answer

Alfred Binet and Théodore Simon developed the first practical intelligence test, known as the Binet-Simon Scale, in 1905. This test was specifically designed to identify students who needed special assistance in school. The test focused on assessing cognitive abilities such as attention, memory, problem-solving, and reasoning skills, which are considered key components of intelligence. The Binet-Simon Scale laid the foundation for modern intelligence testing and the concept of IQ.

Here's why the other options are incorrect:

1.  **Lavator:** Johann Kaspar Lavater was a Swiss pastor and physiognomist, known for his work on physiognomy, which attempted to assess a person's character based on their facial features. He did not develop any intelligence tests.

2.  **Sanguin:** This option is likely a misspelling or a reference to the term "sanguine," which is one of the four temperaments in ancient and medieval medicine. It is not associated with the development of intelligence tests.

3.  **Francis Galton:** While Francis Galton was a pioneer in the study of intelligence and heredity, and he developed statistical methods like correlation, he primarily focused on measuring physical and sensory abilities, believing they were related to intelligence. He did not create a comprehensive intelligence test like the Binet-Simon Scale that directly assessed cognitive abilities. His work, while influential, was different in its approach and methodology from Binet and Simon's.
