Final answer:
Alfred Binet was a French psychologist who developed the first intelligence test, which later became the basis for modern IQ testing.
Step-by-step explanation:
Alfred Binet was a French psychologist who made significant contributions to the field of intelligence testing. In the early 1900s, he was asked by the French government to develop an intelligence test to identify children who might have difficulty in school. Binet's test included verbally based tasks and was later modified by Louis Terman to create the Stanford-Binet Intelligence Scale. This standardized test became the basis for modern IQ testing and has had a lasting impact on the field of clinical psychology.
