Which category of disability most directly involves limitations in intellectual functioning and adaptive behavior?

• A. Physical disability
• B. Intellectual disability
• C. Visual impairment
• D. Speech disorder

Answer: (B)

The main idea here is understanding how intellectual disability is defined. This category is identified when there are deficits in intellectual functioning—things like reasoning, problem solving, learning, and planning—and in adaptive behavior, which covers daily life skills such as communication, social participation, and practical tasks. Importantly, these limitations are present during the developmental period, typically before age 18, and they affect performance across multiple environments (home, school, community). That combination of cognitive limits plus practical, everyday-life limitations is what makes this category distinct from the others listed. A physical disability centers on bodily or motor functioning, a visual impairment on sight, and a speech disorder on communication abilities. While those may co-occur with cognitive challenges, they do not inherently require deficits in both intellectual functioning and adaptive behavior.
