Mental Age is defined as the measure of intellectual performance corresponding to the average cognitive ability at a given chronological age.

Mental Age is defined as the measure of intellectual performance corresponding to the average cognitive ability at a given chronological age.

• A. IQ (Intelligence Quotient)
• B. Mental Age
• C. Stanford-Binet Intelligence Scale
• D. Wechsler Scales

Answer: (B)

Mental age is the level of cognitive development that corresponds to the average performance of people at a given chronological age. In other words, it expresses your thinking and problem-solving abilities as an age equivalent. The description given matches this idea exactly: it’s the amount of intellectual performance that aligns with the average for a specific age. For example, if someone behaves cognitively like an typical eight-year-old but is actually ten, their mental age is eight. IQ is a separate score derived from mental age and chronological age, usually calculated as (mental age / chronological age) × 100. The Stanford-Binet Intelligence Scale is a test that can produce a mental-age estimate (and IQ), while the Wechsler scales are another set of tests that report scores in terms of deviation IQ rather than a direct mental-age figure. Thus, the concept described is mental age.
