For language impairment in a child with Down syndrome, why is mental age used as a performance criterion?

• A. Using chronological age would overidentify language disorders
• B. Using chronological age would underidentify language disorders
• C. Mental age correlates with verbal performance
• D. Language performance is expected to exceed mental age

Answer: (A)

In children with Down syndrome, mental age is often utilized as a performance criterion for language impairment because it provides a more accurate and representative measure of their abilities in relation to their developmental level. This approach helps to mitigate the risk of overidentifying language disorders when using chronological age. Chronological age refers to a child’s actual age based on their date of birth, which may not accurately reflect their language abilities due to developmental delays commonly associated with Down syndrome. Utilizing chronological age could lead to a misinterpretation of a child's language skills, resulting in labeling children as having a language disorder when, in fact, their language development may be consistent with their mental age. Determining language impairment based on mental age allows for a more nuanced understanding of a child's language capabilities by aligning assessments with their cognitive development. This ensures that any identified difficulties are more likely to represent true language impairments rather than just a mismatch between their chronological age and developmental abilities.
