Which term refers to a significant cognitive lapse between ages 3 and 9 that cannot be explained by another identified disability?

• A. Developmental delay
• B. Emotional disturbance
• C. Autism
• D. Deaf-blindness

Answer: (A)

Developmental delay describes a substantial lag in cognitive development between ages 3 and 9 that cannot be explained by another identified disability. This label is used in early childhood and school settings to flag that a child’s cognitive skills are behind age expectations and may need special education services or early intervention while counselors and teachers gather more information to understand the underlying needs. It does not specify a particular disorder, but it signals that a comprehensive evaluation is warranted to determine appropriate supports and monitoring. The other terms don’t fit because they refer to specific conditions or impairments: emotional disturbance centers on persistent emotional or behavioral problems affecting functioning; autism is a distinct neurodevelopmental disorder with social-communication challenges and restricted interests; deaf-blindness describes the combination of hearing and vision loss. None of these describe a broad, unexplained cognitive lag used to trigger early interventions or services in the 3–9 age range.
