what psychologist developed the concept of mental age
Mental age was first defined by the French psychologist Alfred Binet, who introduced the intelligence test in 1905, with the assistance of Theodore Simon. Binet's experiments on French schoolchildren laid the framework for future experiments into the mind throughout the Twentieth Century.owever mental age varies according to what kind of intelligence is measured. A child's intellectual age can be average for his physical age but the same child's emotional intelligence can be immature for his physical age. In this psychologists often remark girls are more emotionally mature than boys in the tween years.
