“For the purpose of this test, we define Mental Age as a measure of a person’s psychological abilities in comparison to the number of years it takes for an average child to reach the same level.
“For example, if your mental age is 10, regardless of your actual chronological age, you are mentally similar to a 10-year-old.”
There are also a number of other tests you can take on the website.
Is mental age a real term?
French psychologist Alfred Binet was the first person to define the term mental age.
He introduced the intelligence test in 1905, with the assistance of Theodore Simon.
Binet’s used it to test schoolchildren in France in the early 20th century.
It was latter revised to become an intelligence test called the Stanford–Binet Intelligence Scales
Henry Herbert Goddard was the first psychologist to bring Binet's test to the United States. He believed that intelligence was a fixed quantity. At that time many peope in the US believed it was hereditary.
However measures such as mental age and IQ have limitations.
