Answer :
A five-year-old child with an IQ of 120 on the Stanford-Binet test has a mental age equivalent to that of a six-year-old. The correct option is B).
Benjy, the five-year-old with an IQ of 120 on the original Stanford-Binet test, has a mental age of 6. This means that his intellectual abilities and performance on the test are equivalent to that of an average six-year-old. The concept of mental age was introduced by Alfred Binet, the creator of the Stanford-Binet test, to assess a person's cognitive development in relation to their chronological age.
In Benjy's case, his mental age being 6 indicates that he performs intellectually at a level typically expected of a child who is six years old. This suggests that he has above-average cognitive abilities for his age. It's important to note that an IQ score of 100 is considered average, so Benjy's IQ of 120 places him above the average range, further emphasizing his advanced cognitive development compared to other children his age.
In summary, Benjy's mental age of 6 reflects his advanced intellectual capabilities, as assessed by the Stanford-Binet IQ test.
Therefore, the correct option is B).
