Answer :
The average seven-year-old child with an IQ of 100 has a mental age of 7.
Mental age is a concept in psychology used to describe an individual's level of cognitive functioning relative to their chronological age. It is often used in intelligence testing, where an individual's performance on cognitive tasks is compared to the performance of others in the same age group. An IQ score of 100 is considered average, indicating that the individual's performance on intelligence tests is typical for their age. Therefore, for a seven-year-old child with an IQ of 100, their mental age is 7 years old, which aligns with their chronological age.
Understanding mental age is crucial in assessing intellectual development and identifying potential strengths and weaknesses in cognitive abilities. In this case, the mental age of 7 indicates that the child's cognitive abilities are typical for their age group. It's important to note that mental age is just one aspect of intelligence assessment and should be interpreted alongside other factors such as social and emotional development.
