Who introduces 'Mental Age' word very first ?

Question

Accepted Answer

Alfred Binet was the first to introduce the concept of "Mental Age." He was a French psychologist who, along with his colleague Théodore Simon, developed the Binet-Simon scale in the early 20th century. This scale was designed to measure the intellectual development of children. The concept of "Mental Age" was a crucial part of this scale, as it represented the age level at which a child was performing intellectually, as opposed to their chronological age. This idea was groundbreaking at the time and laid the foundation for modern intelligence testing.

Now, let's explain why the other options are incorrect:

2. Thurston: Louis Leon Thurstone was an American psychologist known for his work in psychometrics and factor analysis. He is best known for his theory of primary mental abilities, which challenged the idea of a single general intelligence factor. However, he did not introduce the concept of "Mental Age."

3. Thorndike: Edward Thorndike was an American psychologist who is best known for his work in educational psychology and the theory of connectionism. He focused on animal behavior and the learning process, particularly through his famous puzzle box experiments. He did not introduce the concept of "Mental Age."

4. Guilford: J.P. Guilford was an American psychologist known for his theory of multiple intelligences and his work on the structure of intellect model. While he made significant contributions to the understanding of human intelligence, he did not introduce the concept of "Mental Age."

In summary, Alfred Binet is correctly identified as the person who introduced the concept of "Mental Age," making Option 1 the correct answer. The other options, while they represent influential psychologists, did not contribute to the introduction of this specific concept.
