Which of the following is not typically classified as an intellectual disability?

• A. Color blindness
• B. Fragile X Syndrome
• C. Down Syndrome
• D. Prader-Willi Syndrome

Answer: (A)

Intellectual disability involves significant limitations in intellectual functioning and adaptive behavior that begin before adulthood. Color blindness is a visual perceptual difference, not a measure of intelligence, and it does not affect IQ or everyday adaptive skills. So it is not classified as an intellectual disability.

The other conditions listed—Fragile X Syndrome, Down Syndrome, and Prader-Willi Syndrome—are genetic disorders that commonly include cognitive challenges and impacts on adaptive functioning, fitting the typical scope of intellectual disabilities.
