Who coined the term 'Mental age'?

Question

Accepted Answer

The term 'Mental age' was coined by Alfred Binet, which is why Option 1 is the correct answer. Alfred Binet was a French psychologist who, along with his colleague Théodore Simon, developed the first practical intelligence test, known as the Binet-Simon scale. This scale was designed to identify children who needed special educational assistance. In this context, Binet introduced the concept of 'mental age' to describe the level of intellectual development relative to the average intellectual performance of individuals at a specific chronological age. The idea was to compare a child's performance on the test to the average performance of children in different age groups, thus determining the child's mental age.

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

2. Stern: William Stern was a German psychologist who is known for introducing the concept of the Intelligence Quotient (IQ). He proposed the idea of dividing the mental age by the chronological age and multiplying by 100 to get the IQ score. While Stern's work is related to intelligence testing, he did not coin the term 'mental age.'

3. Terman: Lewis Terman was an American psychologist who is best known for revising the Binet-Simon scale into what became known as the Stanford-Binet Intelligence Scales. While Terman played a significant role in popularizing intelligence testing in the United States, he did not coin the term 'mental age.'

4. Wechsler: David Wechsler was an American psychologist who developed several widely used intelligence tests, including the Wechsler Adult Intelligence Scale (WAIS) and the Wechsler Intelligence Scale for Children (WISC). Although Wechsler made significant contributions to the field of intelligence testing, he did not coin the term 'mental age.'

In summary, Alfred Binet is credited with coining the term 'mental age,' which is why Option 1 is the correct answer. The other individuals mentioned made important contributions to the field of psychology and intelligence testing but did not introduce this specific concept.
