mental age
Definition
Noun: - A measure of intellectual development: Mental age represents an individual's level of intellectual ability or cognitive development, expressed in terms of the average age at which that level is typically attained. It is derived from performance on standardized intelligence tests.
Usage
Mental age is a concept used primarily in psychology and educational assessment. It is calculated by comparing an individual's test score on an intelligence test to the average scores of individuals in various chronological age groups. For example, a child with a chronological age of 8 who performs on the test at the level of an average 10-year-old would have a mental age of 10.
Examples
- The psychologist reported that the child's mental age was significantly higher than her chronological age.
- An intelligence quotient (IQ) was historically calculated by dividing mental age by chronological age and multiplying by 100.
- The concept of mental age is less frequently used in modern IQ testing, which now more commonly uses deviation scores.
Advanced Usage
- Discrepancy with Chronological Age: A key use is in identifying developmental delays or giftedness by highlighting a significant difference between mental age and chronological age.
- Historical Context: The term is closely associated with early intelligence testing pioneers like Alfred Binet and Lewis Terman.
Variants and Related Words
- Chronological Age (n): A person's actual age in years from birth.
- Intelligence Quotient (IQ) (n): A score derived from standardized tests designed to assess human intelligence. Historically, it was a ratio of mental age to chronological age.
Synonyms
- Cognitive age
- Intellectual age
Notes
- Important Distinction: Mental age is a or based on test performance, not a description of emotional or social maturity.
- Criticism: The concept has been criticized for potentially oversimplifying the multifaceted nature of intelligence and for its normative comparisons.
Noun
-
the level of intellectual development as measured by an intelligence test
