Binet's concept of mental age refers to the level of intellectual ability that a child displays relative to average intellectual ability at a particular age. If 6-year-olds can complete the puzzle in five minutes, then this is the average level of performance expected for children of that age. Bailey, who takes almost eight minutes to complete the puzzle, is displaying a level of intellectual ability that is below what is expected for a 6-year-old; therefore, Bailey's mental age is lower than six.
