Mental age is a concept that was initially used to compare the intellectual performance of a child to the average performance of children at different ages. However, it becomes less applicable as an individual reaches adulthood because intellectual development and acquisition of knowledge tend to plateau, making it difficult to compare adults' intellectual capabilities in the same way as children's. This limitation has led to the development of other measures of intelligence that can be applied more broadly across all age groups.
